COMPUTER-BASED DYNAMIC ASSESSMENT OF MULTIDIGIT MULTIPLICATION

Design details, operation, and initial field-test results are reported for DynaMath, a computer-based, dynamic assessment system that provid es individually tailored, instructionally useful assessment of student s with disabilities. DynaMath systematically organizes and outputs dat a on student performance on multidigit multiplication problems varying in difficulty and procedural demands entailed in solving multidigit p roblems. DynaMath graphically shows the ''zone of proximal development ,'' those problems most likely to prove susceptible to the next phase of instruction. The program also automatically records multiple measur es of performance in a database and provides a printed clinical report with suggested instructional interventions. DynaMath provides a quali tative record of student performance via annotated real-time replay.
