Digestion (Core) and Flip Thinking
Digestion – something you only want to go in one direction. But learning about digestion doesn’t have to go one way. As we are trying to reduce the burden of homework and to make any time spent working outside class as effective as possible, we’re going to try Flip Thinking.
Essentially, your homework takes place before class and you complete only the objective 1 command terms (the bits you don’t need me for). With that out of the way and a foundation in the language and diagrams of the topic, we can focus on the more complex items together.
Come to class with the objective 1 command terms completed in the Essential Biology for Digestion (Core). I have highlighted them in yellow. This should take no more than one of your study periods. If it takes longer, stop and let me know how far you got, as well as how effectively you were working.
Come to classes prepared with your laptop and don’t forget the resources we have available.
Essential Biology 6.1 Digestion (Core)
Key question: How many links can you make from Digestion to the others topics we have already studied in IB Biology?
I cannot take credit for this idea. Check out these resources:
- Flip Thinking from John Burrell (Click4Biology)
- Eric Mazur’s Science education research group
- Flip Thinking from Daniel Pink
- The Homework Myth by Alfie Kohn
If, however, you find that this helps or hinders your progress, be sure to let me know.
