Enhancing students' conceptual understanding is one of the primary goals of science education. Existing literature suggests that the degree of knowledge integration among students can reflect their level of conceptual understanding. This study focuses on the concept of friction force, constructing a cognitive structure model of friction force to…

Development of cognitive skills is critical for developing the right conceptual ideas in chemistry. Atomic structure, bonding, and associated properties are taught as parts of high school chemistry courses worldwide. The cumulative build-up of misconceptions about the periodic table is to blame for students' poor performance on atoms and…

The main areas of difficulty experienced by those teaching and learning organic chemistry at high school and introductory university level in Ireland have been identified, and the findings support previous studies in Ireland and globally. Using these findings and insights from chemistry education research (CER), the Organic Chemistry in Action!…

Learning progressions, or representations of how student ideas develop in a domain, hold promise as tools to support teachers' formative assessment practices. The ideas represented in a learning progression might help teachers to identify and make inferences about evidence collected of student thinking, necessary precursors to modifying…
