Wow, SApaul, kudos to you for doing this!
I am kind of hesitant to say there are big differences in how women learn vs. how men learn. I've done all my MC learning in either a mixed or all-guys-except-me group. Each individual will have different issues, regardless of gender, although gender & culture may result in different ways of expressing it.
LionLady & Blues are better equipped to address this, I know, but it sounds like this group lacks formal instruction & coaching more than anything. Giving them specific & individual feedback in each exercise should be the most helpful.
slow to let out clutch = either "I don't want to either stall or pop a wheelie" or mistaking slow for smooth. The whole clutch/throttle/friction zone thing needs practic
eyes up = that isn't gender-specific, that's common
leaning = don't really understand the mechanics of pressing on the handlebar to lean the bike. Tend to try to use the body, in the case of women, more likely to use hips
If you don't have the first three, the lines & cornering are bound to be erratic. Hardest for me is to slow entry speed in advance of the turn, then apply smooth throttle to get out. Don't bother with the specifics of suspension/etc until they've got a feel for it beginning to work for them, then you can maybe explain why it works. It helps to emphasize that only experience & practice will make this better--this is very much a progressive skill, one to work on for a lifetime.
Overcoming survival reactions: only practice of new reactions, to supplant the old ones, is effective. So, they must teach themselves slowly & methodically to do this. You can give them the new tools, but they have to want it enough to go out and practice them on their own, repeatedly. Here's the kicker: practice doesn't make perfect. Perfect practice makes perfect. Whatever they practice is what they will do. Therefore, they should expect to continue to need coaching, and also to learn to analyze for themselves what they are doing & how to fix it, checking back with other proficient riders on how their abilities are progressing. That's what a biking community is for.
Civility and democracy both require effort.
