Evaluate

Engage students in activities that help you and them to evaluate their understanding 

During the lesson, it is important to create many opportunities to formatively assess student learning and provide specific feedback that helps them advance their understanding and systems thinking skills. At the end of the lesson, one should evaluate whether students can apply what they have learned in related but novel contexts. For that purpose:

Involve students in formative and summative assessment activities to ensure they have met the targeted learning objectives and have developed the core understandings needed to productively engage in all components of the learning sequence.

The "Let's Think" activities interspersed in the example module create diverse opportunities to formatively assess student learning and provide specific feedback to advance their understanding to meet the lesson's learning objectives. 

These activities also help students evaluate strengths and areas needing improvement in their learning. As part of the summative assessment, we suggest implementing an activity that requires students to apply their understanding to analyze a different system of interest. This summative assessment could be completed individually or in small groups, inside or outside the classroom. 

An example of this type of summative assessment is included at the end of the example lesson as a "Let's Apply" (LA) activity focused on the analysis of less commonly known greenhouses in our atmosphere.
