This study aims to evaluate students' ability to process the context information embedded in chemistry problems. To achieve this goal, a diagnostic measurement instrument was developed, comprising 28 short-answer items embedded in seven context-based chemistry tasks. Four hundred and ninety-three ninth-graders took part in the testing in Jiangsu,…

Online metacognitive skills are the real-time awareness of cognition, which can effectively promote science learning and improve performance in solving scientific problems. Therefore, it is important to enhance and diagnose students' online metacognitive skills in science education. This study aimed to evaluate ninth-grade students' online…

Interdisciplinary approach is viewed as the best way to learn about and perceive complex scientific phenomena in the real world; therefore, students need to develop interdisciplinary habits of mind in K-12 science education. This article provided a framework for understanding middle school students' interdisciplinary competence that included four…

Science educators have highlighted the need to develop students to integrate knowledge across science disciplines to address real-world issues. However, there has been little research about the development of interdisciplinary assessment instruments. In this research, the instrument that measures the level of upper-secondary school students'…

Chemical symbol representation is a medium for transformations between the actual phenomena of the macroscopic world and those of the sub-microscopic world. The aim of this study is to develop an instrument to evaluate high school students' chemical symbol representation abilities (CSRA). Based on the current literature, we defined CSRA and…
