Reflection: Rigor Biological Classification - Day 1 - Section 1: Hook


The commit and toss strategy (some call it snowball strategy) is a simple way to promote writing and critical thinking. Before the students crumple and toss their papers, they must think about the question being posed, commit to a response and describe their thinking. The anonymity of the activity encourages students to respond even if they are unsure of the “right” answer.

In this lesson, I added the "extra" - write a response and return it to the original author as a way to help students compare their ideas to the thinking of a peer and initiate a collegiate conversation. This simple addition to the strategy increases rigor, providing opportunities for the students to examine their own ideas and provide feedback on the ideas presented by others. The thought process involved is meta-cognitive. Not only do they need to think about and write down what they think, they also need to think about what others think (perhaps modifying their own thinking) and be able to communicate this understanding of the ideas of others.
