There is no a specific sub-Forum on iRV2 for home-schooling while living in an RV. But, there are members here that do it and a quick search shows that there are many articles on-line about the topic.
So, why not start a discussion. Maybe use the Lifestyles Forum (maybe in the Full-timer's sub-forum) - use as generic of a title as you wish and see what happens.

iRV2 is so large now that it is often in the top 5 returns on most internet Search Engines when searching for RV related information, so interested persons might find you and join-in.
Best luck and safe travels
