This past school year I started posting a weekly Quote of the Week to accompany a Video of the Week. The goal being to start each week with some thought provoking material for students to ponder. Ideas which had very little to do with content and very much to do with self discovery. Most weeks I matched the quote with the content of the video, but sometimes mixed up topics for extra connections/conversation.
If this sounds interesting, I made a “40 Week Deep Thinking” document. Currently, all videos work but they are mostly YouTube links and have broken in the past.
