Online teaching tools

We may use this space for sharing our ideas, experiences, questions, and answers as we get prepared to online teaching.  Please use the comments area for this purpose.

Questions to our administrators (who seem to left us to ourselves):
  1. Which software solutions are available at SIU? Are new purchases considered?
  2. Are there docu-cameras available?  Where?  Would SIU buy some for Math Dept? Should we buy our own for preparation videos at home? 
  3. Same question concerning other software.  How to record and edit videos?  Can they be posted on personal blogs?  Elsewhere? (I run a blog for every class.)   Etc., etc.
  4. Can we get a professional help (training and Q&A session)  that will address our specific math teaching needs?  For instance in Nc 356 for all math instructors, some time at the beginning of the next week.
  5. Is there a chance that the final exams can be taken in May on campus? That would be a great deal! It would solve the major headache-inducing problem.

For now, potential software to consider:

If you want to learn programming Processing
try this fantastic series of youtube lectures by A. Shiff.
He actually follows P2.js,  a sister version of Processing.
They are almost identical.

Start here 
(Youtube lets you speed up the videos).

You might like also this nice short intro to the online version of P5.js.
