A new Twitter chat for AP World History teachers begins next week on Monday, 1/12/15. The hashtag is #whapchat and the topic for the first chat will be about teaching the different essay formats.
The moderator will be Angela Lee who teaches in the Boston, Mass area. You can read her blogpost about the launching of the chat here. Her blog also has links to resources including good Pinterest boards.
The chat will be a slow chat which means that one questions will be posed when the chat opens and remain open for 24 hours. You can reply to the question and conversation any time during the day of the chat. The chat will probably open at 6 am eastern time.
