Lesson Plan "Integrating PISA Standards and CER Framework in Teaching Molar Concentration of Solutions" (Grade 8)

This resource presents a comprehensive short-term lesson plan (KMJ) for 8th-grade chemistry under the "Solutions and Solubility" unit, focusing on the topic "Molar Concentration of Substances in Solutions." The lesson features an innovative integration of PISA evaluation matrices and the CER (Claim, Evidence, Reasoning) framework. Students act as independent experts evaluating a real-world carbonated drink label against WHO health regulations to calculate sucrose concentrations and reason about commercial food marketing. Includes structured self-assessment via a "Cognitive Radar" reflection sheet.
