We're working with a hybrid approach and we start the semester by introducing 3D learning in conjunction with the CER (claims, evidence, & reasoning) framework. Early on we do a lot of modeling of science practices. As we go through investigations, we discuss how they can be adapted for different grade levels. We also use video analysis. Once the teacher candidates have lots of ideas for getting started, then we do the lesson planning. I found that setting up screencasts for assignments and lesson planning allows students to work at their own pace. Then we can use Zoom for collective sensemaking and idea generation, rather than going over assignment specifications. What have you found helpful so far?
Hope you're having a good semester!
