#9. Robots & Mixed Reality in Education?

2011-02-09T15:01:00.001-05:00

"Robots are all about people" (Cynthia Breazeal, TEDWomen, December 2010). In her TED talk, Breazeal focuses on the humanistic side of robotic technology and how such technologies affect the way people interact with robots. It seems we tend to develop affective bonds (however loose they may be) to robots. If robots are all about people, I believe robot-human interactions have the potential to greatly enhance learning - particularly in conjunction with the mixed reality technology that Breazeal shows us near the end of her TED talk.

Education research has shown that learning in a social context is more effective than learning in isolation, and that affective involvement/investment (on the part of the learners) in such learning further enhances learning. If robots have a way of tugging at our heart strings, this could very well be an effective way to pull learners into all sorts of learning! How could this work in a classroom situation? What would it look like? More on this later as I continue to think about this while working on my class presentation about Conversation Analysis...

#8: Distributing Situated Cognition to Mimic Generalizable Knowledge

2010-12-20T15:37:00.007-05:00

Update on Project Natal
In my October 21, 2010 blog post on situated learning spaces, I mentioned Project Natal's virtual boy named Milo (there's also a virtual girl named Kate), and posted a 2009 demo launch of Milo. Peter Molyneux, head of Microsoft's European games division, has since appeared on TEDGlobal to talk about Project Natal (July 2010), where he showed the real Milo technology on TED's stage:

We see the demonstrator interacting with Milo using body gestures, facial gestures, and voice - all of which needs to be "taught" to Milo.

Milo's Mind as Metaphor of Knowledge Building
What really interests me about Milo is what Molyneux says in his TED presentation about Milo's mind: "Milo's mind is in a cloud". In other words, the more people who use Milo, the more objects he'll learn and recognize. Fascinating! To me, this implies that Milo's artificial intelligence is distributed, and Milo's mind is the synthesis of training combinations contributed by a community of Milo users. Milo's mind is a wonderful metaphor for collaborative knowledge construction, where Milo's mind represents a knowledge community's World 3 Rise Above knowledge artifact, and the community of Milo users is the knowledge community.

Situating Milo's Distributed Mind
In my October 21, 2010 blog post, I had hypothesized that "the more the situated learning context approximates a realistic context of the domain of study, the deeper and more meaningful the learning will be", implying that Milo could contribute to deeper situatedness in wider contexts.

Since then, I have re-read Carl Bereiter's 1997 book chapter, Situated Cognition and How to Overcome It. He mentions what he and Scardamalia (1989) have termed intentional learning, which has 3 goal levels:

Task completion goals - to be completed immediately (e.g., assignment due date tomorrow); World 1; highly situated
Instructional goals - to be completed summatively in the near future (e.g., end of the course); world 2; less situated; somewhat transferrable
Knowledge building goals - may extend indefinitely into the far future and past; World 3; weakly situated (i.e. immediately situation); highly transferrable

In my December 7, 2010 blog post, I mentioned Bereiter's reasoning behind why it would be prudent to overcome situated cognition - situated learning is inversely proportional to generalizability of that knowledge. Thus, an individual's knowledge would be high transferrable if that knowledge was learned with an intentional orientation toward knowledge building goals.

Continuing on this train of thought, when I consider the "learning" that Milo "does" as he is being used by multiple members of the Milo user community, I would say that almost all of these learnings are for task completion goals. Thus Milo's artificial intelligence should be highly situated and therefore highly ungeneralizable. If we assume that Milo will have a large and active globally-distributed user community, this alone would exponentially increase Milo's potential learning situations/contexts. If Milo is taught by this large globally-distributed user community to recognize an object - a chair for example - in multiple and varied situations, then he should be able to recognize chairs of all types and across all situations. In other words, the object "chair" mimics generalizability. Have I found a way to achieve a mimicry World 3 with a low-level goal of task completion - by exponentially increasing learning situations contributed by a large knowledge community?

This brings to mind the authors of Wikinomics (2008) and Macrowikinomics (2010) Don Tapscott and Anthony Williams' idea of Murmuration Macrowikinomics. Here's a narrated video metaphor of it:

Tapscott is careful to note that "...this is not a collective intelligence or collective consciousness of course, because individual birds are not intelligent or conscious...". He describes the thousands of starlings moving as one mass, as a "...loosely conjoined network of relationships and impulses" - much like a globally-distributed Milo user community?

Tapscott asks: "Will we come to consider networking as the neural roots that connect human beings in a way that creates something fundamentally new?" I do not hesitate to say "YES - but.....!" Much like Milo's "mind" (i.e. artificial intelligence) cloud, that grows as his distributed user community "teaches" him more, Milo's knowledge base will only ever mimic World 3, and appear to be generalizable. What allows Milo's mind to mimic generalizable knowledge is the numerous situations in which he has learned the same thing. If millions of users around the world "teach" Milo to recognize the object known as "chair", presumably, they're all using different kinds of chairs available in their homes. These chairs could vary greatly in age, design, style, size, etc. Hence, Milo acquires the ability to recognize any chairs that match any one of the millions of chairs his distributed user community has inputed into his memory stores - giving the appearance that Milo has generalized recognition of the object called "chair". Milo's seeming intelligence is indeed artificial.

Back to Tapscott's question. I think that networking neural roots connecting people would create something fundamentally new, but not necessarily better. Like Milo's mind cloud, this new thing would only mimic World 3 due to the exorbitant number of task-completion-oriented contributions to its knowledge base from its massive and globally-distributed user community. Highly transferrable World 3 knowledge can only be created with an orientation toward knowledge building goals, and must consider the far past and continue into the far future (Bereiter, 1997).

#7: Knowledge, Mind, and Assessment

2010-12-07T16:07:00.010-05:00

What is Knowledge?
Knowledge is socially negotiated, situated, and distributed. It is what Sir Karl Popper would term a "World 3" artifact, it's own entity, taking on a form of its own (what Scardamalia and Bereiter would call a "conceptual artifact") within a knowledge community.

Knowledge is situated in the sense that concepts are situated within the context of the surrounding environment, and these concepts are progressively developed. It is a product of the activity, context and culture in which it is learned and used. Conceptual knowledge as a tool is only fully understood through its use. Furthermore, its use changes the user's world view, causing the user to adopt the belief system of the culture in which the conceptual knowledge tool is used (Brown, Collins, and Duguid; 1989). Brown, et al. (1989) propose a "cognitive apprenticeship" model of education, which promotes learning through activity, tool, and culture. Cognitive apprenticeship is supported by collaborative social interaction and social construction of knowledge. It honours the situated nature of knowledge, embeds learning in activity, and makes deliberate use of the social and physical context.

Bereiter (1997) argues for the value of overcoming situatedness of cognition by creating World 3 knowledge objects that are transferrable across different situations. He points out that the problem with situatedness of cognition is that as one learns more about a phenomenon, one knows increasingly more about the phenomenon as framed within that situation, making this knowledge less likely to be generalizable to other situational contexts. Furthermore, treating all knowledge as situated would make knowledge objects invisible. Bereiter (1997) calls us to treat ideas as "objects of inquiry" (p. 18), requiring "Disciplined movement back and forth between (Popper's) World 1 (the physical world) and World 3 (immaterial world of knowledge and abstract objects)" (p. 18), yielding the "hypothetico-deductive method" and endless possibility for theory development, problem solving, and design. Incidentally, Sir Karl Popper's philosophy of knowledge is based on his proposition of 3 worlds:

World 1 - the physical world
World 2 - the world of the mind (mental states, ideas, perceptions)
World 3 - the immaterial world that is the product of the human mind (e.g. the concepts and ideas represented or expressed by books, papers, paintings, symphonies; but not physical books, papers, or paintings themselves)

What is Mind? Where Does Knowledge Reside?
Sebastian Seung of MIT discusses his theory of mind: "I Am My Connectome" at a TED Talk (July, 2010):

Nueroscientists since the 19th century have hypothesized that one's memories, personality, and/or intellect also reside in the connections between one's neurons. This would imply that knowledge resides in our neural connections. These connections form what Seung calls one's "connectome". According to Seung, neural activity encodes our thoughts, feelings, and mental perceptions; but neural activity can also cause our own neural connections to change (hence changing our connectome). Conversely, our experiences can change our connectome. Thinking can change one's connectome. Neural activity constantly changes in our brain, but it is the brain's neural connections (which make up the brain's neural network) that determine the pathways along which this neural activity flows. These neural pathways as a whole is the connectome. The Seung Lab at MIT seeks to read memories from connectomes, and Seung is leading the new field of connectomics to test these hypotheses.

As I consider both Bereiter and Seung's theories of mind, I see the one commonality is that they both see knowledge as residing in connections and composed of networks of connections. In Seung's case, these connections are of a physiological nature residing in the human brain. In Bereiter's case, these connections are conceptual in nature, residing in World 2 and World 3; with collaborative knowledge building as the vehicle by which individual learner's conceptual connections combine and build upon those of other learners in the creation of a World 3 knowledge object.

The Nature of Knowledge: Implications on Assessment
Bereiter (1997) points out that situativity theorists have not advanced any educational ideas due in part to their failure to define the purpose of education and to their confusion between process and product. The collaborative knowledge building that I have witnessed in my experience as a graduate student, classroom teacher, and instructional leader aligns with Bereiter's assertion that "knowledge implicit in the process" (p. 23) should be distinguished from "knowledge that is the product of the process" (p. 23); and yet, this distinction is not recognized in K-12 classroom practice, curriculum policy, or assessment and evaluation policy. Our education system is still misguidedly preoccupied with learning goals and the embodiment of knowledge in the form of reports and presentations, failing to see knowledge taking a form that can be worked with or even packaged and sold (Bereiter, 1997). This is decidedly antiquated thinking, considering our knowledge society's wealth will come from knowledge work - no longer from manufacturing as in the industrial society of old. "What distinguishes knowledge work is not using knowledge by creating or adding value to it" (Bereiter, 1997: p. 23). This is not to say that we should do away with learning goals, merely that the focus should shift from these to learning for deeper understanding and the construction of knowledge through collaborative means supported by technology.

Hutchins and his colleagues developed the distributed cognition approach in the 1980s as a way of understanding collaborative work practices, or "cognitive systems" - complex interactions between multiple people, artifacts to perform an activity, and technological systems (Rogers, 2006). There are two levels of analysis: (1) analysis of 'the propagation of representational state across media' and (2) analysis of human interactions (i.e. the problems, the breakdowns, distributed problem-solving, role of non/verbal behaviour, coordinating mechanisms, communication during collaboration, knowledge sharing/accessibility).

While I can see the value of having a distributed cognition framework with which to study the dynamics of collaborative work, I find that this approach emphasizes the interactions enacted to complete the task, and does little to examine closely how ideas/memes/theories evolve within and among a community. Furthermore, the distributed cognition approach does not seem recognize knowledge as its own entity, as a 'product'. Rather, it acknowledges knowledge as a process but focuses on the knowledge community's development of that process, not on the conceptual evolutionary process of knowledge in its own right.

This is especially problematic when one considers Carl Bereiter's (2002) contentions that that the mind is not a container, knowledge and conceptual artifacts do not reside in learners' minds, and that the mind does not reside in the head of a person, nor does it necessarily reside within one person. For Bereiter, knowledge objects and conceptual artifacts belong to World 3.

If distributed cognition analysis of a knowledge community can be used in such a way as to reveal how the community's mind/cognition is distributed among the community, and hence, trace how the conceptual development of knowledge as a conceptual artifact is gradually constructed within the community; then distributed cognition could be a powerful approach to prove Bereiter's theory of mind, and aid in the classroom assessment of collaborative knowledge building in asynchronous online environments.

In this regard, Activity Theory (Hew & Cheung, 2003), developed by Alexei N. Leont'ev and Sergei Rubinshtien, seems more promising. Based on the premise that tools mediate between subject and object processes, rules mediate between subject and community processes, and roles mediate between community and object processes; one can use this framework to analyze several combinations of any three processes as illustrated by any three edges of the following triangles:

(Hew & Cheung, 2003)

If the basis of our knowledge society's economy is going to be knowledge work, then it stands to reason that schools must teach learners to be proficient knowledge workers. Assessment is vital to this learning process, for teachers and learners alike. Applying Gunawardena et al's (1997) 5 phases of active knowledge construction and Henri's (1992) 5 types of critical thinking (Hew & Cheung, 2003) to assess individual and community knowledge construction would be very useful in this regard. In addition to being good knowledge workers, today's learners will need to become excellent collaborators as well. With this in mind, it would be helpful to apply Rourke et al's (1999) 3 constructs of social presence and affective responses (Hew & Cheung, 2003) to assess social presence, and to apply Kirkley et al's (1998) 7 means of moderator assistance (Hew & Cheung, 2003) to assess facilitation skills - or what I like to call "cognitive leadership" skills. Of course, I do not mean to suggest that we implement the above mentioned frameworks in their pure form, but rather to reform our current assessment and evaluation policies and practices based upon a combination of these frameworks.

#6: Preparing Students for the 21st Century Knowledge Age

2010-11-18T03:07:00.182-05:00

If this is what life is going to be like in 2019, what skills do today's students need to be successful in the Knowledge Society? How can we help them develop these skills?

Readings
Lately, I've been reading about Knowledge Building and Online Communities:

"Chapter 8: Putting learning it is proper place", in Education and Mind in the Knowledge Age (Bereiter, 2002)
Social and Technological Innovations for a Knowledge Society (Scardamalia, 2000)
Technology in Support of Collaborative Learning (Resta & LaFerriere, 2007)
From Practice Fields to Communities of Practice (Barab, & Duffy, 2000)
Issues Barab raises about the notion of community
Collective cognitive responsibility for the advancement of knowledge (Scardamalia, 2002)

One can look up all the various 21st Century Skills projects to see a list of skills, which commonly include creativity, digital literacy, critical thinking, and problem solving:

21st Century Learning Initiative (Canadian Council of Learning)
enGauge 21st Century Skills (Metiri Group)
Partnership for 21st Century Skills
Assessment & Teaching of 21st Century Skills (CISCO, Intel, Microsoft)

Teacher A, B, and C (Scardamalia & Bereiter)

Dr. Marlene Scardamalia and Dr. Carl Bereiter, founders of the Institute for Knowledge Innovation and Technology at OISE / University of Toronto, maintain that schools need to adopt a culture of collaborative knowledge building if they are to prepare our society for the Knowledge Age. Whereas traditional schools adhered to what they call a "Teacher A model" - teaching reduced to tasks and activities; I find that much of our current schooling adheres to what they have termed the "Teacher B model" - a focus on learning objectives/outcomes/expectations with students' responsibility directed at tasks and activities, and the teacher taking on the cognitive responsibility. The education utopia Scardamalia and Bereiter espouse is the "Teacher C model". In this model, strategic cognitive activity is turned over to the students. Whereas Teachers A and B roles resembled that of "Engineer", Teacher C does what Teacher B does - but with the added "objective of turning more of the learning process over to the students" (Bereiter, 2002; Ch. 8, p. 39).

Collective Cognitive Responsibility (Scardamalia, 2002)

Scardamalia defines Collective Cognitive Responsibility as the condition when learners "take responsibility for knowing what needs to be known and for insuring that others know what needs to be known" (2002, p. 2). She and Bereiter assert that schools actually withhold cognitive responsibility when they operate on a Teacher A and/or Teacher B model. They espouse that engaging a class in collaborative knowledge building, particularly in an online discussion forum such as Knowledge Forum, effectively enculturates students into the collective cognitive responsibility of their community knowledge. Scardamalia goes on to elaborate on her 12 Knowledge Building principles (2002, p. 9-12), the basic building blocks of Knowledge Building (KB) pedagogy:

Real ideas, authentic problems
Improvable ideas
Idea diversity
Rise above
Epistemic agency
Community knowledge, collective responsibility
Democratizing knowledge
Symmetric knowledge advancement
Pervasive knowledge building
Constructive uses of authoritative sources
Knowledge building discourse
Embedded and transformative assessment

The following have been my KB-related learning goals since I first learned about KB 10 years ago at OISE (Master's work):

how to implement KB in a publicly-funded classroom
possible modifications to the pure form of KB for realistic classroom implementation
how to recognize true KB
how to foster true KB in the classroom, given the realities of the publicly-funded classroom

My classmate, Kyungmee, writes: "Moreover, according to Scardamalia (2002)’s paper, knowledge creation processes are basically CHANCY. '… knowledge creation depends on chancy processes of discovery and invention.' Then, how to define knowledge creation processes? Is there any particular steps or conditions? If not, how teacher can try to teach or provide students knowledge building opportunities?"

I have been wrestling with this very question since I first learned of constructivist knowledge building at OISE 10 years ago! I find that the concept of KB is far too open and abstract to be implemented in its pure form - especially if KB is to be implemented in public schools which are mandated to follow provincial curriculum expectations.

I did a pilot project in a few schools at my school board where I tried to add some structure to KB - a compromise between KB and the realities of time and curricular constraints that public school teachers face. Teachers chose a curricular area to address, in which their students would begin the unit using the inquiry process infused with face-to-face (f2f) KB cross talks and virtual KB Knowledge Forum discussion. We used Wiggins & McTighe's Understanding By Design framework to co-design and backward map a curricular unit. To satisfy current provincial assessment and evaluation policy which states that summative evaluation can only be of a product, students were then required to create a final flashy ICT-infused project to demonstrate their learning.

I'm sure Bereiter and Scardamalia would cringe at the way I chose to go about implementing KB in these pilot classrooms, but I had to start with where the teachers were at, while considering the realities of policy and classroom constraints that these teachers face.

Systemic Changes Needed for Knowledge Building in Ontario

I see 2 systemic changes necessary for authentic KB implementation in the classroom and Teacher C-ism:

Provincial Assessment and Evaluation (A & E) policies must recognize that Knowledge Building (KB) and collaboration skills can and should be measured, evaluated, and reported upon. As per Bereiter, A & E policy should recognize that KB is productive work, IS learning, and is a necessary skill for success in the knowledge society.
To avoid Teacher B-ism (a focus on learning goals), is not, in my opinion, a realistic endeavour given our provincially mandated curriculum. To get rid of a mandated curriculum is unrealistic as well, because I do think that a society should have a certain baseline of common knowledge in order to function cohesively. However, might there be some sort of a compromise, where provincially mandated learning expectations exist, but does not drive education? How might a "Teacher B.C" model work?

While it is nice to dream up how we might make systemic and policy changes, I am more interested in how we can make KB work within our existing reality. Anyone have any other suggestions for implementing KB in classrooms?

Assessment of Knowledge Building

Page 31 of the Ministry of Education's 2010 Growing Success document on assessment and evaluation (A & E) has a nice summary table of assessment for/of/as learning.

I would agree that assessment as learning (a.k.a. formative assessment) is key in helping students develop their collaborative knowledge building skills, as well as developing their metacognition of this. It is unfortunate that under current A & E policy, formative assessment is not something that can be quantified and reported upon formally on a student report card. Since Scardamalia and Bereiter emphasize the importance of these skills for success in the knowledge society, I think it is problematic that this is not addressed in the report card.

Page 11 of the Growing Success document defines "learning skills work habits", and are part of the student report card. I think that the Ontario report card should also have a "Collaborative Knowledge Construction" section, much like the Learning Skills section, in which various component skills related to collaborative knowledge building are listed, and teachers may assign qualitative "grades" to each skill.

My classmate, Vincent A. asks: "How can educators effectively and authentically assess knowledge building, especially if there is no final tangible product?"

I'm quite sure that Scardamalia and Bereiter would disagree that "there is no final tangible product" in knowledge building. As a member of a knowledge building community, once you put forth an idea, that idea becomes an artifact - its own entity, and belongs to the community collective (not to the person who contributed the idea). In other words, the community collective is made up of tangible ideas. The final tangible product would be the community's Rise Above.

Knowledge Building in Wikis?

I like the idea of a class/group wiki. Though I'm not sure about 2 things:

Is there community knowledge building occurring, and if so, how might we track it? I ask this because a wiki is usually a piece of work that demonstrates a group/community's understandings. It doesn't actually show the discussion around it (unless the students use the discussion forum within the wiki), and hence, we can't see the conjectures, the theorizing, etc. We just see the factual information that the group has come up with via various resources.
How do we assess wiki work? Provincial A & E policy states that we can only evaluate students on an individual basis, not on a group-by-group basis. So how do we evaluate individual students' wiki work? Going back and analyzing various iterations of wiki pages for each student is tedious and unrealistic. Is there a better way? How do you evaluate this?

Another Way for Knowledge Building Communities to Use Wikis

Prof. James Slotta of OISE (my PhD supervisor) has created a framework called Knowledge Community and Inquiry (KCI), in which groups of students work within a science inquiry model and contribute to a community wiki, then are challenged to solve an authentic problem in which they use the wiki as a resource to do so.

#5: Harnessing the Power of YouTube for Distributed Cognition

2010-10-29T17:34:00.011-04:00

I've been learning a lot about knowledge communities - including Reciprocal Teaching - (Ann Brown, Anne Marie Palincsar), collaborative knowledge construction (Marlene Scardamalia, Carl Bereiter), and distributed learning (Yvonne Rogers, Michael Cole & Yrjo Engestrom). However, when I think of "the tubes" (i.e. YouTube, SchoolTube, TeacherTube) and all the learning opportunities they have to offer via traditional transmission instructional strategies - the very strategies we are desperately trying to steer away from - I find myself at a crossroads. The examples of YouTube learning below have absolutely ZERO aspects of community knowledge creation other than YouTube's role as video tutorial repository. Granted, YouTube does allow for the posting of comments for each video, but I have yet to see this feature being used in a way that remotely resembles a community discourse with the goal of deeper understanding. What follows are some examples of the learning power of YouTube.

Khan Academy
Not sure if anyone has heard of the Khan Academy? Salman Khan, who quit his job in finance, runs this non-profit educational organization out of a closet in his home. He regularly creates tutorial videos about an astounding number of science and math topics, and posts them to YouTube. Here's a chemistry video about the atom, proton, neutron, and electron:

Common Craft
Then there's Common Craft, who makes wonderful videos to explain various technologies (e.g. wikis, blogs, augmented reality, etc.). Here's Common Craft's YouTube channel. Their latest video is about augmented reality:

My 8-Year-Old Nephew
Just to illustrate my classmate, Maria's, point about the power and appeal of YouTube, I'd like to use my 8-year-old nephew as an example. Aside from a few ukelele classes he got at his after school program, he has taught himself how to play the ukelele and the guitar by surfing YouTube. YouTube has fed his motivation to learn both these instruments so much, that he now creates his own ukelele songs (sometimes with accompanying lyrics). He also gets his parents to take him to local open mic events at least once a week so that he can perform his music. Furthermore, he gets his mom to video-record his performances so that they can be uploaded to YouTube. Makes me wonder what he'll do at age 10. Here's my nephew's YouTube channel if you're interested. My favourite song is "I Don't Know" - hysterical!!!

YouTube for Knowledge Communities & Distributed Cognition?
Contrary to everything I'm learning in graduate school about learning, YouTube, for the most part delivers knowledge in the most pedagogically traditional way. There is no knowledge community discourse, no distributed cognition, no acknowledgement/accommodation of individual learning styles...it is simply transmission teaching in a digital medium! Yet, it's undeniable that such instructional YouTube videos have learning value. So how might we better use YouTube to enhance learning, promote distributed cognition, and foster knowledge communities?

My first thought is to make better use of the YouTube's commenting functionality, and use this as a community discussion forum. However, I think it is better to establish an online learning environment on some other platform, and refer to specific YouTube video resources as the need arises. This way, the instructor has more tools to work with, in terms of creating an effective online learning environment. Furthermore, the instructor and participants (through their virtual social presence) may have a clearer picture of how the community's cognition is distributed and therefore take reasonable actions in their responses to focus on topics/directions that suit the group's needs.

Case Study Approach
A more concrete strategy to ensure distributed cognition and distributed problem solving within a knowledge community would be to design a specific and authentic problem to be solved by the group as a whole. Some of my classmates have suggested the case-study method to achieve this.

Knowledge Community & Inquiry (KCI)
Another framework that comes to mind is Knowledge Community and Inquiry (KCI). The theoretical tradition of classrooms as knowledge communities (Brown & Campione, 1996; Scardamaila & Bereiter, 1999; Hakkarainen, 2004), engages students with a sense of “collective cognitive responsibility” for continuous community knowledge advancement (Scardamalia, 2002). KCI is a recent effort within this tradition espoused by James D. Slotta and his colleagues (e.g., Slotta & Peters, 2008; Peters & Slotta, 2010). KCI engages the students and teacher as a knowledge community, building a cooperative “knowledge base” that serves as a resource in scaffolded inquiry activities designed to target specific learning goals. I believe KCI can be a powerful approach to focusing a knowledge community's distributed cognition on the collaborative inquiry and problem solving.

#4: Video Games & Augmented Reality As Situated Learning Spaces

2010-10-21T17:32:00.018-04:00

Quest To Learn is a 1-year old public middle school in New York City based on a curriculum of educational video gaming and digital media.

"Games as learning spaces" - learning at Quest to Learn is structured in a game-like way. Students modify and create video games to demonstrate their learning, and assume defined roles during this process. "Systems thinking" is the theoretical framework on which the school's methodology is based.

As I ponder about situated cognition (i.e. learning is inseparable from doing), it seems to me that educational video gaming and creation is the ultimate situatedness for learners - short of immersing them in real domain under study! What I find particularly interesting, is that these students are potentially simultaneously being immersed in 2 cultures - the culture of the subject area content which the video game addresses, and the culture of gamers and gamer creators. Thus achieving "double situatedness" (if these is such a term)!

My classmate, Jillian A. writes: "The theory of legitimate peripheral participation (LPP) states that a newcomer to a community plays an authentic role (or set of roles) on the 'periphery' of community activity, participating 'in the actual practice of an expert, but only to a limited degree and with limited responsibility for the ultimate product as a whole' (Lave & Wenger, 1990; p. 14)". So while these learners may be on the periphery of the subject matter community for which they are creating their video games, their game modification and creation processes place them at the very centre of the gaming community.

Dr. Jennifer Jenson and Dr. Suzanne de Castell have done a lot of research on educational gaming. Recalling a paper I read of theirs last year, I remember their distinction between "as if" and "just like". I believe they were arguing that while simulations gave learners an experience "as if" they were completing an authentic task in a given subject domain, educational video games could give learners an experience "just like" they were doing the real thing. The "just like" experience was deemed a more effective learning experience. I'll have to dig up that paper...

An incredible development in the gaming world - Project Natal's "Milo" - has exciting implications for further and deeper situatedness that promises to blur the line between the virtual and real world:

Pranav Mistry of MIT has created SixthSense technology, using gestures and digital media to further blur the distinction between the physical and the virtual world:

If situatedness closely approximates reality, would this necessarily lead to deeper and more meaningful learning? Why or why not?

I will continue to think about this. My initial thoughts are that the more the situated learning context approximates a realistic context of the domain of study, the deeper and more meaningful the learning will be. This may be due to a heightened sensory experience afforded by the technology contributing to the realism of the learning context.

#3: SMART Board + Science = Situated Cognition Knowledge Community Wiki?

2010-10-16T19:50:00.005-04:00

I recently ran a F2F workshop for elementary preservice science teachers to introduce them to SMART Boards and to get them thinking about how best to use this technology with students to enhance science teaching and learning. As a way to organize activity centres, I created a wiki.

For 1 hour, the preservice teachers, in groups of 4, worked through 4 activity centres: SB1, SB2, SB3, and SB4. Each "SB" wikipage followed the "5E's" science instructional model: engage, explore, explain, extend, and evaluate. This was a deliberate attempt to model how the 5E's could be used to frame a lesson, since they would soon be learning about the 5E's instructional model in their science education class.

I took a Piagetian approach - having students work on their own, then with a partner, and finally within a group of 4 preservice teachers. Thus progressing from invidividual to socialized thought. As the students worked through the tasks outlined on the various SB wikipages, they often had online videos that they could view on their own. They were instructed to complete the "explore" tasks in pairs and also to "extend and evaluate" their new learnings by discussing within their group of 4 to connect these learnings with science teaching strategies. "Homework" consists of adding these connections to the wikipages' "extend and evaluate" sections, and asynchronous discussions about this may take place via the discussion forum accessible by clicking on the "Discussion" tab at the top of every wikipage.

The F2F portion of the class went extremely well. The preservice teachers were immersed in the SMART Board material presented, and as I was dropping in on their conversations, I could tell that they were looking at these resources through the lens of science educators. Did I succeed in situating them in context of teachers considering how best to use a technology for science education? I think so! They have until December 9, 2010 to complete their homework, and I'm looking forward to seeing how this community will take shape online.

#2: Piaget, Vygotsky, Situated Cognition Vs. Mitra's SOLE & Granny Clouds

2010-10-15T21:00:00.024-04:00

I've been reading about social and cultural influences on learning, as well as Situated Learning:

Piaget, Vygotsky, Situated Cognition
Where Piaget asserted that children developed from the individual to the socialized (i.e. nonverbal autistic thought --> egocentric thought & speech --> logical thinking & socialized speech), Vygotsky argued that children developed from the socialized to the individual (i.e. social --> egocentric --> inner speech).

In situated cognition theory, activity and situations are integral to cognition and learning.

Vygotsky's developmental theory and Situated Cognition theory can indeed work in tandem! These theories imply that:

Learners need to be situated within a collaborative learning context so they may co-investigate socially, eventually leading to internalized learning for each individual.
These co-investigation activities must be authentic tasks, situated within the context of the subject domain of study, such that learners see themselves as practitioners of that domain.

Both #1 & #2 can be done face-to-face (F2F) or online, but I always think that a blended model (e.g., F2F + online) works best.

Mitra's SOLE and Granny Clouds
Having read about Piaget and Vygotsky's somewhat opposite theories of child development, it has made me give more thought to Sugata Mitra's TED talk about The Child-Driven Education:

The idea that children will collaboratively learn with digital tools they've never used, heard of, or seen before; inspite of purposeful lack of instruction and scaffolding - is evidence to me that collaborative learning is natural to the human condition. This is incredibly profound! Furthermore, Sugata Mitra's work seems to support Vygotsky's developmental theory, rather than Piaget's; as it seems that the children in his studies developed their skills and knowledge socially before the new knowledge became internalized within each individual child.

In his TED talk, Mitra mentions 2 quotes from Sir Arthur Charles Clarke, that I find very profound:
"A teacher that can be replaced by a machine, should be."
"If children have interest, then education happens."

The second half of this TED talk is particularly intriguing. Sugata Mitra's work on Self Organizing Learning Environments (SOLE) and the Granny Cloud. He informally organized children into small groups and gave each group a set of questions, as well as the freedom to access the internet with 1 laptop, discuss amongst their group, drop in on other groups, and no other scaffolding. He's found that such informal groupings and vague scaffolding sets the stage for children to self-organize as a learning community, producing deep learning. His Granny Cloud work involved 200 volunteer English grandmothers who regularly taught English to children in India via Skype.

Mitra Vs. Situated Cognition
Mitra's SOLE work is in sharp contrast to my classmates' (Scott J.'s KEC note #1286 and Chad L.'s KEC note #1310) and my own thinking (KEC note #1404), that collaboration skills need to be explicitly taught. In Mitra's SOLE work, this is clearly not the case! Is it possible, that by explicitly teaching collaboration, we stifle the degree to which children can collaborate effectively and learn deeply? It also interesting to note the absence of any situatedness in Mitra's SOLE work. In fact, all of the learning tasks that he presented to various populations of children in various countries (India, Italy, England) were intentionally out of context and in some cases, not even in a language that the children knew! Perhaps then, situated cognition is not a necessary component of effective/deep learning, merely an enhancing component?

Mitra's speculation: "Education is a self organising system, where learning is an emergent phenomenon...". He estimates that it will take 5 years and under $1 million to prove this experimentally, and that's what he intends to do. Mitra's theory is a direct contradiction to Brown, Collins, and Duguid's "cognitive apprenticeship" model (1989), where learning is embedded in activity and deliberate use is made of the social and physical context to immerse learners in the culture of the knowledge domain under study. The one idea that Mitra's work and the Cognitive Apprenticeship model have in common is that learning is supported by collaborative social interaction and social construction of knowledge. As previously noted, Mitra's work also contradicts the notion of "situated cognition", in which activity and situations are integral to cognition and learning.

So who's right? There seems to be supporting evidence for all arguments! Perhaps it's a question of efficiency. If we leave learners to collaboratively self-organize, they will learn deeply if given enough time. If we situate (via cognitive apprenticeship) and scaffold learners' collaborative learning, they will learn deeply, perhaps in less time?

Finally, Mitra emphasizes that the future of educational change is "A question of attitude, not technology", and breaks down "The Arithmetic of Change" for us:
1 billion children
100 million mediators
10 million SOLEs
$180 billion
10 years

This indeed is an exciting and optimistic outlook for education! Perhaps there is hope yet of rocketing the education dinosaur into the 21st century...

#1: Let the Learning Begin!

2010-09-23T14:38:00.009-04:00

This learning journal is part of an assignment for my CTL1608 graduate course, "Constructive Learning & Design of Online Environments", with Dr. Clare Brett at OISE/UT. Although I've taken courses about constructivist learning and computer-mediated learning, I have yet to take a course about the design of online environments (presumably for the enhancement of learning).

The course began a week ago, and I'm already 1 week behind due to my mad scramble to compile my Vanier Canada Graduate Scholarship application - a futile exercise, I know (since the odds are so low), but still a worthwhile learning experience in my opinion. Next on my list are the SSHRC and OGS scholarship applications.

I'm intentionally beginning this learning journal before I've done any of the course readings because I'm curious to see how my perspectives will change as I progress through this course for the next 3 months!

What I know...
...about learning...
Constructivist learning is an active and social process by which learners engage with new concepts and with co-learners, to actively construct knowledge and understanding of the topic of study. This is achieved through the active collaboration of learners during tasks and discussions to arrive at a shared understanding of the concept/topic of study. Learners must have access to prior learning as they also engage in a continuous cycle of new knowledge creation and reflection. Reflection not only informs new knowledge creation, but also helps learners to develop awareness of their own metacognition. Learners must be able to personally connect with the material, and I believe that learning is enhanced if the learner also develops an emotional connection with the material, or with the learning process itself in their interactions with their co-learners. Thus the learning must occur in an authentic and relevant context. This aligns with my personal philosophy of learning, in large part because I am heavily influenced by Marlene Scardamalia and Carl Bereiter's work on constructivist knowledge building.

...about the role of the teacher...
As for the role of the teacher in all this? The teacher is seen more as a facilitator than the gatekeeper of knowledge, as in more traditional school settings. My favourite metaphor for this is that the teacher is no longer the "sage on the stage", but rather, the "guide on the side". I wish I knew where this metaphor came from, but it is so widely used in education and training, that it's now been incorporated into the common rhetoric of both fields. Personally, I think that there are still situations in which direct teacher instruction is warranted, but let it be only 50% (preferably much less) of instructional time! As the facilitator of a constructivist learning environment, the teacher guides students gently to keep them from straying too far off their focus, and to prompt/question them when necessary to nudge them towards deeper inquiry and understanding. The teacher is teaching students how to learn, rather than teaching them what to learn (i.e. the content).

...about online learning environments...
From a constructivist standpoint, an online learning environment should have the following functionality:

asynchronous threaded discussion: so that learners may use this forum to exchange, share, analyze, and build upon each other's ideas, and information gleaned form external resources. This also allows learners to access these vital discussions at anytime from anywhere, thus the learning never has to stop.
synchronous chat: so that learners can collaborate in real time to discuss ideas, share/analyze data/information, and perhaps work with each other to plan how they will complete their collaborative learning tasks
permanent record of prior learning: so that learners may revisit their prior learning and reflect upon "where they've been", compare/contrast this with "where they're at", which may inform them about "where they're going"

From my own observations and experiences as an online learner, I think the following should be considered when designing an online learning environment:

simplicity: a simple interface with lots of white/blank space and minimal text is attractive to the eye. Whenever possible, replace text links with icon links.
2 (ok, maybe 3) clicks deep: the learner should never have to click more than 2 or 3 levels deep to access the webpage they're looking for.
multi-media: the social presence of the instructor and students directly correlates with students perception of course effectiveness. Hence, the environment should allow users to easily interact with each other via self-made video- and/or audio-recordings. A bonus would be to allow real-time video and/or audio chat. This also addresses differentiated instruction, in which personal learning preferences/styles are taken into account.
gallery: a webspace where learners can share and celebrate their "final" products/demonstrations of learning. The gallery should also allow for peer review of work, much like how YouTube has a "Comments"section below the posted video.
assessment: Having used Knowledge Forum (KF) with grade 6, 8, and 12 students; I know how much learners appreciate KF's built-in assessment tools which can tell users how many notes students have posted and read, note reading and response interaction patterns among a class, and individual student progress in vocabulary growth. Not only did these tools inform learners of their own progress, but these tools also served as a motivational force! Furthermore, these tools help the teacher form a "big picture" understanding of the online class' dynamics and can quickly inform the teacher about students who may need a little more support and guidance.
virtual world: this is my personal bias. I can't understand why video games and digitally animated films can look so incredibly beautiful and yet, online learning environments do not. No wonder students love to spend time playing video games! Who wouldn't want to stay in such a graphically stimulating environment? It would be wonderful if an online learning environment had the look and feel of a virtual world, without having to move an avatar - I am quick to throw the latter point out there because I've experienced how frustrating this can be (e.g. Second Life).

Here are some online learning sites that I've created for various workshops and tutorials within the Toronto District School Board (TDSB), but they are not what I would consider "constructivist":

TDSB Blogging with Blogger: an online tutorial about how to use Blogger to create a class blog
Podcasting & Vodcasting for Learning: an online tutorial about how to create a class podcast/vodcast using Blogger
Dare 2 Dream: Spirit of Dr. King: created for Black History Month (2008) for use in elementary classrooms for the NE1 family schools in the TDSB. Goal was to highlight leadership and spur students to think about how they might take up a leadership role to work towards improved equity in their community

My favourite classroom blog/podcast is done by a TDSB teacher named Chris Borges, called Mr. Borges & the Blog Squad. Although I have used PBwiki and Wikispaces in the past, I don't have any classroom examples to share.
