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…

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…
