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,…

Luo, Tian; Wang, Jian; Liu, Xiufeng; Zhou, Jiangping – International Journal of Science Education, 2019
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…

He, Peng; Liu, Xiufeng; Zheng, Changlong; Jia, Mengying – Chemistry Education Research and Practice, 2016
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…

Wei, Silin; Liu, Xiufeng; Jia, Yuane – International Journal of Science and Mathematics Education, 2014
Scientific models and modeling play an important role in science, and students' understanding of scientific models is essential for their understanding of scientific concepts. The measurement instrument of "Students' Understanding of Models in Science" (SUMS), developed by Treagust, Chittleborough & Mamiala ("International…

Liu, Xiufeng; Waight, Noemi; Gregorius, Roberto; Smith, Erica; Park, Mihwa – Journal of Computers in Mathematics and Science Teaching, 2012
This paper reports a feasibility study on developing computer model-based assessments of chemical reasoning at the high school level. Computer models are flash and NetLogo environments to make simultaneously available three domains in chemistry: macroscopic, submicroscopic, and symbolic. Students interact with computer models to answer assessment…

Problems of validity and reliability of concept mapping are addressed by using item-response theory (IRT) models for scoring. In this study, the overall structure of students' concept maps are defined by the number of links, the number of hierarchies, the number of cross-links, and the number of examples. The study was conducted with 92 students…
