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,…

This study aims to provide preliminary validation for a newly designed instrument to evaluate teaching effectiveness through student classroom engagement and learning gains. The instrument is titled the Middle Semester Classroom Survey of Student Engagement and Learning (MS-CSSEL); it consists of 31items to measure student classroom engagement in…

The aim of this study was to develop a scale to measure students' STEM continuing motivation (CM). In accordance with the conceptualisation of CM by Maehr (1976. Continuing motivation: An analysis of a seldom considered educational outcome. "Review of Educational Research," 46(3), 443-462. doi:10.3102/00346543046003443), we define STEM…

This study intends to develop a standardized instrument for measuring classroom teaching and learning in secondary chemistry lessons. Based on previous studies and interviews with expert teachers, the progression of five quality levels was constructed hypothetically to represent the quality of chemistry lessons in Chinese secondary schools. The…

This paper describes the development of Connected Chemistry as Formative Assessment (CCFA) pedagogy, which integrates three promising teaching and learning approaches, computer models, formative assessments, and learning progressions, to promote student understanding in chemistry. CCFA supports student learning in making connections among the…

Service learning typically involves university students in teaching and learning activities for middle and high school students, however, measurement of university students' self-efficacy in science communication is still lacking. In this study, an instrument to measure university students' perceived self-efficacy in communicating science to…

Energy is one of the most central and richly connected ideas across all science disciplines. The purpose of this study was to develop a measurement instrument for assessing students' understanding of the energy concept within and across different science disciplines. To achieve this goal, the Inter-Disciplinary Energy concept Assessment (IDEA) was…
