Reflection: Coherence Enzymes and Substrate Concentration Lab - Section 4: Independent Practice

 

The close read strategy is an effective tool for the science classroom, especially as it relates to students reading lab procedures.  So often, students will fail to read a lab and rely on the summary provided during guided practice.  To eliminate this, I require students to perform a close read for an allotted amount of time before I allow them to collect materials for the lab.

I try to walk around and ask specific questions about  the lab procedure to asses whether students know what they are expected to know or do during the lab. As a form of assessment, ask students to show you how to adjust the pH or substrate levels.

It is also helpful to link struggling readers with stronger readers so that they can work through the close read together and everyone will be clear about what to do.
