Taking the same graphics as in this post, but presenting them differently.
In the previous post, I presented a screen cast explaining, in a very text-booky way, how rainbows form. Today, I am using the same graphics, but I have broken the movie into six individual snippets.
I’m starting out from the schematic that concluded last post’s movie and ask five questions that you could ask yourself to check whether you understand the schematic:
Ideally I want to link the other five of the movies into the one above, but I haven’t figured out how to do that yet, so here you go for the answers:
- Why does light change direction as it enters a different medium?
- What happens at the back of the raindrop?
- Why is the white light spit up into all the colors of the rainbow?
- How do the three processes above play together in a raindrop?
- Why does our eye see the rainbow in an orderly fashion rather than just a jumble of colors?
What do you think of this way of presenting the material? Do you like it better than the textbook-y movie? I’m curious to hear your opinions!
For both this and the other way of displaying the material, I am toying with the idea of adding quizzes throughout the movies, in a programmed learning kind of way. But considering all the pros and cons, I haven’t made a final decision on it yet. What do you think?
