Re: [Phys-L] more prepping

No, not a pandemic.

It’s only a measure of vaccine industry desperation.

Hi Folks --

Your institution needs to make plans for what to do if students
are kept out of the classroom for an extended time.

Even if you're not the dean or even the department chairman, you
know who is, and you ought to be asking questions, and contributing
suggestions if you can.

Even at the personal level, you might want to think about pivoting
to /online/ teaching. You can prepare for that in various ways.
For starters, figure out how to do screencasting. Pick a suitable
screencasting package
and figure out how to use it.

Before you buy any software, read the fine print on what hardware
it supports. For example, if you have a ten-year-old laptop, the
graphics card is probably not suitable. Screencasting is a rather
graphics-intensive task.

If you have a desktop, you can buy an upgraded graphics card for
a modest price, if necessary.

Also you will need a good-quality microphone. Something that
clips onto your lapel is OK. One that attaches to your head
or ear is usually better. Wired is fine. Bluetooth is fine.
Virtually all laptops support bluetooth nowadays, and if your
desktop doesn't you can fix that with a cheap USB dongle.

Ask around. There is probably somebody near you who knows
how to do this and can help you get started.

Look at Khan Academy videos to see what a proven-successful
style looks like. In particular, you do NOT need to capture
your face. Screencasting -- which just captures the diagrams
and words -- works fine.

A typical LMS such as moodle does /not/ do screencasting, but
deals with many other parts of the problem, e.g. distributing
and collecting assignments.

It's better to figure this out /before/ any additional manure
hits the ventilator.

The number of covid-19 cases outside of China is growing faster
than exponentially. Previously it was doubling every four days,
but now it is doubling every three days. Exponential growth is
absolutely horrifying, but this is worse.

If this ain't a pandemic I don't know what is.
