Using spreadsheets in the classroom is an idea that I never thought about. I had never encountered there use in my own classes through school and my experience with them has mainly been through labs in my physics courses at the university. For this reason they have appeared, to me at least, to be very boring. Thinking back on my usage of them now I realize that there are some features about them that I could utilize in a classroom. Here is an idea for a lesson plan that I could utilize in a High school physics 20 class.
One of the topics in a physics 20 course is projectile motion. So here is my lesson plan. Prior to the class I would set up a curved ramp, similar in form to a ski long jump ramp, and roll a ball down it. Using a digital camera with a prolonged exposure and a strobe light I would be able capture the motion of the ball at different points of its flight. I could record the data of its motion in a spreadsheet and graph it. In the classroom I could bring the ramp in to demonstrate the motion as well as provide the students with the spreadsheet and graph so that they could see a quantitative analysis of its motion. Along with this information I could provide the students with some questions so that they could apply there developed understanding to other situations.
If time would permit I could also adapt this idea by have the students perform the experiment and analyze the data in Excel so that they could also get experience with this computer tool. This lesson plan would provide a visual demonstration, auditory explanation, and hands on experience, hopefully appealing to all the students learning styles.
Perhaps this way the concept would be better understood.
