I've been asked to teach the local junior high and high school shop teachers....
Two things I thought to focus on for starters is to get them set up with an easy to use sharpening jig—which leads me to the Wolverine. And I'm thinking for bowls, to show them the Ellsworth grind.
Going over safety and watching the teachers turn also seems worthy of a fair bit of time.
I appreciate any advice!

You have a good framework laid out within to teach. Since your students are teachers who have a different focus than just learning how to turn a bowl it may be an advantage to work on sharpening first.
When I teach beginning bowl turning. I teach the Ellsworth ground gouge and I sharpen all tools for the first couple of class projects. I don't have them use a bowl gouge on the first project.
3 hours
The first project I do is a carving mallet from 4x4x8 or a 3x3x8 using a spindle roughing gouge, parting tool and a spindle gouge. The roughing gouge is an easy tool to start people on and using it to turn a cylinder gets over any inititial trepidation. I teach them beads and coves on the end of the blank where the handle will be. Do a row of beads, turn them off with the roughing gouge. Turn a row of coves, turn them off with the roughing gouge. Use the spindle gouge to shape and refine the mallet.
They can use this forever to drive in spur centers.
3 hours
The second project is a bowl from a 3.5x9" disc mounted on a screw in the Chuck.
They learn the scraping cut, bevel riding push cut. They turn the tenon with a spindle gouge.
Shape the outside of the bowl then mount and hollow it with a thick wall for drying. I have them use a round nose scraper on the inside bottom. This is the first tool I have them sharpen,
3 hours
Third class is a bowl from a half log initially mounted between centers..
Elllsworth gouge to rough to round in a crude bowl shape. Turn the rim. Turn the foot and tenon,
Connect the foot to the rim with a pleasing curve. On this bowl I introduce the pull cut. Mount in the Chuck and hollow for drying. In this class I teach them sharpen the bowl gouge with the Ellsworth jig.
I show them all a demos of sharpening then while they are roughing the bowl I take each one to the grinder have them go through the sharpening motion with the grinder off. I bring the grinder up to speed turn it off and have them sharpen one side as the wheel slows down. Then bring it up to speed turn it off and have them shape the other side. Then turn it on and have then sharpen the tool with the grinder running. I satay on the grinder not running until the have the basic moves. The stay in the grinder running turned off stage until they are doing well. Then they are ready for grinding under power. Then they have to have me watch them sharpen the next time. After that they have a license to sharpen as needed.
3 hrs Dry bowl class - I like to have them microwave one of the bowls above.
In this class if I make a judgement call on which if any students to teach the flute up shear cut.
In class of 8 this would usually be 2-3
3 hrs Natural edge bowl
3 hrs - turning beads on bowls and
