The basic idea behind Interactive Teaching is two fold. The first part is:
- Students read before lecture
- Students go online to answer questions about the reading and to ask questions about the reading
- The instructor reviews answers left on the net looking for areas where most/all of the students get it or where they don't get it
- This data informs how lecture is done
- A question is posed to the class
- All students respond via clickers, whiteboards, or colored index cards marked with letters
- Responses quickly assessed by the instructor.
- If most are correct the answer is confirmed and explained briefly
- If there's a mix of right and wrong answers the students are asked to turn to their neighbors to defend their answers. After which the students are re-polled.
So, I can have them read, or I can record a lecture and have them watch it, and then answer questions before they come back to me. I get to see their responses before class and I can easily tailor my lesson to fill the holes they still have in their understanding. Or, I can use this technique for a very easy pre-assessment before I start a new unit.
Below is a quick screen-capture I did to show you how to do this and how my first such lesson looks like. (note: for ease I tried out the video upload function within Blogger, you can see the results below. Not very acceptable. For a clearer version got to my copy at falconphysics.blip.tv. There you can also download the full resolution screen capture if you want.)
