Reflection: Routines and Procedures Modeling Archimedes' Principle - Section 2: Guided Question


Within this lesson, I introduce a routine for solving physics problems called G.I.R.L.S. that helps introduce to the idea that scientists use logic when solving complex problems. I did so because I want students to move away from treating working as though it represents a viable solution. I want students to make connections and use their mathematical reasoning to support their claims, not simply box answers that are numerically accurate. 

In my experience, students are more likely to recognize gaps in their judgement when using the G.I.R.L.S. protocol rather than just plugging numbers into an equation. Students have provided feedback that the image and solution steps of the protocol were the most useful to them because the image allowed them to identify what was occurring in the problem and the 1-2 sentence summary in the solution step made it easy for them to check if they actually answered the question or identified the unknown.
