So why is this post titled “Sub Videos”? When I first began merging tablet and screencasting technologies to create instructional video, one of my favorite applications was for sub assignments. I would simply record myself modeling a few problems for students…have the sub play those videos…have the students solve some related problems…have the sub play solutions to those videos, etc. It worked like a charm (at least I thought…). See example video below:
Despite initial “success”, after presenting at CUE in Palm Springs last month, something struck me. I was in the middle of my standard discussion about Blooms Taxonomy, and how the true “flip” does not involve homework with lecture, but intentionally matches the “community” (classroom) with learning activities appropriate for the community (higher end Blooms). Conversely, matching the “individual” (outside of class time) with learning activities appropriate for that space (lower end Blooms). See image below:
While giving that presentation, I realized that my students were back in San Francisco, with a substitute, watching videos IN THEIR COMMUNITY SPACE (classroom) of me solving problems as I would IN THEIR INDIVIDUAL SPACE! Because my students were all together, I was missing an opportunity to use video as an inquiry tool, and instead, using it as I normally would on the back end of an inquiry cycle, as a tool delivery medium. So, the last few times I have missed class since CUE (happens often given the arrival of my second child!), I have been experimenting with using video in a way that values the community, promotes inquiry, and models how I normally would carry out class if I was there. Rather than solve problems, I have been presenting open ended scenarios for students, and given a set of prompting questions, instructing the sub to have students discuss possible solutions to the scenario. Often, I have coupled the situation with follow up videos that provide further explanation, but NOT UNTIL the initial inquiry scenario is presented. Below are a few examples:
Pre Video Question: Does Bromothymol change color in an acidic or basic environment? Justify by writing a chemical reaction to describe the process.
Pre Video Question: Can you explain this observation using what you know about ideal gas behavior?
