If You Only Concentrate on One New Strategy, Make it CER
Every science teacher understands the value of students being able to explain phenomena, not simply to define vocabulary words or to answer questions that require them to show what they have memorized. But teaching students to construct explanations is challenging.
IQWST makes the process easier by supporting teachers and students with a systematic approach that includes the now well-known CER framework. The framework divides explanations into three logical, manageable, and teachable components for middle school students: Claim, Evidence, and Reasoning. We developed the CER framework alongside teachers who were frustrated by their students' responses to oral and written questions --- typically responding in such brief ways that teachers could not adequately assess their students' understanding. The CER framework was born and developed in IQWST as a result of teachers' desire to better support their students as scientific thinkers and writers.
