Hello,
I'm just checking in to continue a conversation we were having last summer when the new Big History was posted. I thought we had reached a place where OER admin was going to consider keeping both classes up and running. I just saw in a thread that the old version will be done away with in a few weeks.
Now, I did see the Google Drive that was shared with all of the materials. But my concern with not making the old version publicly available seems valid, as it's going to make it harder for those pitching it to high school administrators to get it accepted in the curriculum. In my case, I have many people in my district that would like Big History done away with. Deleting the curriculum from it's online space will give them ammo to possibly argue that even OER didn't have faith in the course. This could be devastating! If you want to promote the new version, go for it! But please please please don't do away with something so many people have spent years building.
