The video is just me working through what is known as an analytic question. This is a question designed to 'test' a students problem solving ability on the Physics 30 Diploma exam (a standardized exam in Alberta). The question requires a student to use at least 2 physics principles to solve the question and is regarding as quite challenging. The one I chose to demonstrate is a common one that tends to come up on the exam. It is projectile motion inside an uniform electric field.
I used a tablet I had at school to write with and used the built-in microphone on my laptop to make the video. The software I used was the SMART Notebook software that many teachers use with their whiteboards. I was going to use Jing but it only allows five minutes of recording.
As mentioned above to create one video of approx. 10 minutes in length took me over an hour, so needless to say very time consuming for a teacher but could be used to have students explain concepts to each other. I think screencasting is a very interesting, new and novel way to present a project topic and share with the class.
Kristian,
ReplyDeleteI think you are right on the money when you suggest this would be a good learning tool for students to do.When a person does these screencasts they have to really know their stuff- and if you were to assign each student to do a problem like this as a screencast ( they could all do different problems) I would think this would really solidify their understanding of these problems. An extra bonus would be if you had a place, like a wiki or blog where you could post everyone's problems and so students could review from each other's work.
Kristian,
ReplyDeleteSo in your class, would you use screencasting to present a topic during the class period? I am wondering if it would really be worth taking the time to create a screencast when you could directly teach it to the students. That is my problem with many of these tools because it is hard to justify the time it takes to create lessons using them. I do like the idea of the students creating a screencast though because it would solidify their understanding as Mary said above.
