Reflection: Continuous Assessment In and Out of Cells - Conclude your Own - Section 3: Explore


The student work (SW1SW2,SW3SW4) shows that the Says-Means-Matters strategy has improved the students' ability to make clear observations and differentiate them from the inferences needed for the analysis of data. In all cases I can see that the information gathered on the "Says" and the "Means" portion of the half sheet made it without major attempts at explaining into the Lab report. The strategy acts as a scaffold to organize the students' thinking about the data they collected during the experiment (NGSS Practice 4: Analyze and Interpret Data).

The same work also tells me that there is an opportunity for growth in drafting conclusions. The "Matters" portion of the sheet did not yield as good results as in the previous lesson. On this occasion,  the students jump to some rather inelegant conclusions (i.e. "This matters because if you drink gatorade you will grow bigger" or "You could water a plant with coke") which did not make it into the lab report. The conclusions written in the lab report were really an attempt to answer the suggested questions, which also made their organization haphazard.

In future lessons, as well as when teaching this lesson again, I will need to make the connection between the "Matters" and the conclusions clearer, possibly making use of the RERUN strategy.
