The redox reaction is a core concept of upper-secondary school chemistry curriculum. Accurate diagnosis of students' conceptual understanding of the redox reaction from a cognitive structure perspective is critical for enhancing their understanding of chemical concepts. This study utilized Bayesian networks to investigate the cognitive structures…

Distractor-driven multiple-choice assessment items and Rasch modeling were used as diagnostic tools to investigate students' understanding of middle school chemistry ideas. Ninety-one items were developed according to a procedure that ensured content alignment to the targeted standards and construct validity. The items were administered to 13360…

Cognitive psychologists and measurement specialists have identified several methods for assessing students' knowledge structures. Applications of the Concept Structure Analysis Technique and MicroCAM (a computer-aided method) are described. Other research into schema knowledge is noted. These assessment procedures provide information about student…
