Chemical thinking is widely acknowledged as a core competency that students should develop in the context of school chemistry. This study aims to develop a measurement instrument to assess students' chemical thinking. We employed the Essential Questions-Perspectives (EQ-P) framework and Structure of Observed Learning Outcome (SOLO) classification…

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…

Chemical equilibrium is so important domain knowledge in chemistry that the corresponding organisation of concepts in students has been an interesting but unsolved issue. A deeper understanding of how students organise the relevant concepts in long-term memory is beneficial to develop more targeted teaching practices. This research utilized the…

Chemical symbol representation is used extensively in chemistry classrooms; however, due to its abstract nature, many students struggle with learning and effectively utilizing these symbolic representations, which can lead to ongoing failure in subsequent chemistry learning. Taking the perspective of learning progressions, this study identifies…

A total of three hundred and fifteen (n = 315) gifted students from the 10th and 12th grade from the United States (n = 102), China (n = 125) and Germany (n = 88) were surveyed regarding their motivation and self-regulation in chemistry learning. A 3 x 2 x 2 MANOVA revealed "nation" as having the largest major effect on these variables.…
