Amy, what an incredible breakdown of the challenges faced when teaching synchronously via zoom. Teachers who have mastered their classrooms are clearly up against HUGE challenges and have to learn and master a whole new way of teaching. However, now with the added layer between teachers and students via Zoom or any other platform, this challenge cannot be faced by teachers alone. Tool makers are a crucial part of bettering and providing functionality that will ease and enhance online teaching. Every teacher, I'm sure had a unique system in their classroom. I think niche tools could be useful for catering to specific teaching modes. However, this also sets up a challenge for students to then have to learn the ins and outs of a new tool.
