Assessments are built in throughout every module. Each lesson contains a Check for Understanding, an embedded formative assessment that provides teachers with insight into student thinking at the moment when it’s most important. Conceptual Checkpoint assessments allow teachers to measure student progress across multiple lessons to ensure they are on track to build the knowledge of the module. Each module also contains either an Engineering or Science Challenge, which arrange for students to apply the knowledge they’ve attained throughout the module to solve a real-world problem or investigate a phenomenon. The End-of-Module assessment, a cumulative summative assessment at the end of each module, allows students to apply their new knowledge in a different context to explain how it applies to a related phenomenon.
