Guidelines for Creating Response Videos

Keep it simple.

Videos should not be more than about 3 minutes long.

Videos should focus primarily on the mathematics. Demonstrations and visual aids are great, but don’t spend a lot of time on skits, music, special effects, or other fancy stuff.

Response videos don't have to use elaborate technology. You can record someone at a chalkboard, or hold the camera so that you can can see someone working on a piece of paper. Of course, you are welcome to use whatever technology best helps you communicate your thinking (presentation software, interactive whiteboards, smartpens that can record what you write).

Explain why.

Don't just give an answer to a challenge. Explain how and why you got your answer. Try to make your reasoning as clear as possible to the viewer. Remember that some viewers may not have solved the problem completely, and some may have solved the problem in a very different way that you did. It may help to practice explaining your results to someone unfamiliar with the problem.

Be nice.

This community is about collaboration and teamwork, not about trying to outdo one another. Avoid condescending, bragging, or ''showing off'' in your videos and comments. If you want to make reference to another response video, please do so respectfully (even if you disagree with their results).

Sound check!

Before posting, be sure that you can see and hear everything in your video. A smartphone can be a great choice for recording a response video, but it may help to make a few test videos first to be sure everything comes out the way you want it to.
