1. The document proposes a formative structural assessment system using concept maps to identify students' strengths and weaknesses, provide effective feedback, and be easy to use. 2. The system works in four stages: students complete a computer-based concept map, their map is evaluated against a referent map, students are shown missing links and examples to understand relationships, and they receive additional instruction by clicking on links. 3. The system is designed to be automated with minimal teacher input to successfully improve students' conceptual understanding through an effective formative assessment process.
