## Reflection: Developing a Conceptual Understanding Introducing Gravitational Field Strength - Section 3: Video Notes with Pause Points

We have been learning about the best practices for studying and learning physics for several weeks and have used video notes with pause points earlier in the semester. I decided that it was time to give students another way to interact with video pause points. I thought this would be an easy task since students already knew how to write summaries and the only thing that was different was the particular content we were studying.

I projected the video at the front of room and had the entire class follow along, I noticed that some students were having trouble keeping up with the timing of the class. They kept asking me to go back to previous pause points. Since the time I allotted to this section of the lesson was limited, I decided that I should upload the video to Edmodo and students could listen to the video at their own pace before moving on to the next section of the lesson. This ability to control the pace of the video would allow students to obtain the information they needed and allow students to observe the mathematical reasoning behind the model of the gravitational field strength.
