The document presents an evaluation plan for a unit on the future and technology. It includes the unit's general objective and learning aims. For each learning aim, it outlines diagnostic, formative, and summative assessments. Diagnostic assessments activate prior knowledge. Formative assessments monitor progress through classwork and activities. Summative assessments evaluate achievement, using methods like posters, dialogues, and tests. The plan aims to monitor student progress, determine achievement of aims, and provide feedback to support self-regulation. However, an over-emphasis on marks could undermine the formative purpose if students only focus on grades.
