How to Reteach and Model in the Online Classroom

Overview
360 degrees of teaching
Think about giving students an experience where you are guiding them at the beginning, the middle and the end. It is a wrapping of teacher touches.
Example
Preview of unit with learning targets - announcements
Support difficult content with pre-teaching videos/resources.
Example-Cont’d
Reteaching: follow up
Other Options
Analyzing your lessons
Look at a class you have previously taught.
Things to consider:
Analysis of Physics B: 4.1
Students tend to struggle with explaining how to charge an aluminum can.
Current announcement supports 4.2 but not 4.1.
Insert video into lesson content to help students “see” how to charge things: Crash Course-Electric Charge
Use common comment to guide back to video if have not watched, and if have watched, schedule chat.
Most commonly used comment to help guide students to retry:
1) There are three different ways to charge an object: friction, conduction, and induction.
2) Charge is always conserved and you will need to show you are upholding that in your explanation. For instance, you can charge the balloon by rubbing it on your hair (friction), but how is the balloon becoming charged from rubbing?
3) If the balloon is charged and brought near the can, the can will polarize. Polarization is temporary. If the balloon is removed from the situation, the can will no longer be polarized and will not be charged.
4) If you charge by conduction, the objects must touch, and charge will transfer from high density of electrons to low density of electrons.
5) If you charge by induction, the polarized object must then be grounded in order it to end up with a charge.
Pushing Further
Do you ever wish that a certain lab, assignment, etc asked students to dig deeper or asked a specific question? Why not put that in the comments?
Electricity can be compared to flowing water in pipes. For resistivity, the water would take longer to reach the other end of the pipe for a few different reasons: if it is clogged or not (good or poor conductor), the length of the pipe (longer wire equals more resistance), and the width of the pipe (wider pipe means easier flow of water just like a larger cross sectional area means less resistivity).
Sweating is quite an interesting process. Your body producing water on your skin, the water absorbs heat from your body which causes the water molecules to gain additional kinetic energy. That increase kinetic energy makes it more easy for the water molecules to evaporate. When water molecules evaporate, there is a large amount of energy that is lost to the remaining water, and the remaining water molecules are also cooler than before evaporation. This makes the sweat colder than your body, so the sweat can absorb more heat from your body and start the process again. This is why after you sweat, you become chilled after a while if you have stopped exercising and not toweled off.
