Comment on Pseudoteaching: MIT Physics by Physics is fun

Physics is fun — Mon, 13 May 2013 07:04:02 +0000

I think some people are just too lazy to learn difficult material. Everyone thinks it’s the teacher’s fault. There’s a personal responsibility.

Comment on Subversive Lab Grouping Game by leticia moran

I added the following group:

Flowers: Rose, Tulip, Violet, Lotus (also car)

I also needed two groups of 5, so I added Krypton (for element, but some students might think planet) and Daisy (for Disney character, which is also a flower)

I found myself going off on this in a rant: http://youtu.be/6mhGQGpFmk4 and then I remembered that you’re where I first learned what pseudoteaching is. I have a huge problem with this when it comes to all of those fun and amazing demos that we chemistry teachers do.

[…] what Ramsey did so nicely was he described his transition away from simply flipping lectures and pseudoteaching and into a more pure and natural and humanizing form of teaching and learning – one designed […]

Comment on Video Analysis of a Bouncing Ball by Rutger Ockhorst

Hi Frank,
I’ve been doing that exact same bouncing ball experiment since I started teaching (four years ago). The results are indeed beautiful. One thing I noticed this year is that some students, when discussing their results, feel very compelled to mention air resistance, even saying that it’s the main source of energy loss. I discovered it’s really quite hard to convince them that air resistance in this case is completely negligible and that it can be seen from their own data. It’s a really great activity that gets you a view inside your students heads.

This year my whole energy program (for 15/16 year old high school students) was focussed around the bouncing ball. We had the kinematics part behind us, so to start up energy I gave them some whiteboard questions. Find the maximum altitude of a ball launched from the ground with 10 m/s (using kinematics). Try to discover an equation that gives the altitude for any speed. When we have this, I take their results and label two colums: one ‘gh’ and the other ’1/2 v^2′. We discover that for the entire ball’s flight, the total of these two quantities is conserved. Now if every thing in the world had the same mass as the ball, we’d be done. But a bowling ball dropped from 1m does do a lot more damage to your toes than a tennis ball. This gets us into the importance of mass. The derivation is not at all rigid, but I found that most of my students grasped the message and the importance of it. What’s more, they have essentially derived it themselves and it really sticks. I really sensed an air amazement and achievement among my students when we did this.

Comment on Khan Academy is an Indictment of Education by Yash

Khan Academy is about reviewing the basic and learning things at your own pace. It is successful helping with the fundamentals. Also it is free.
