Liu, Chen-Chung; Wen, Cai-Ting; Chang, Hsin-Yi; Chang, Ming-Hua; Lai, Po-Han; Fan Chiang, Shih-Hsun; Yang, Chih-Wei; Hwang, Fu-Kwun – Instructional Science: An International Journal of the Learning Sciences, 2022
Virtual labs provide space for students to iteratively test, observe, and revise their understanding so as to improve their scientific literacy. However, one of the challenges that students face is that they need to think and act like scientists so as to be sensitively alert to methodological flaws and various sources of error. This study thus…

Chang, Hsin-Yi – Interactive Learning Environments, 2017
Two investigations were conducted in this study. In the first experiment, the effects of two types of interactivity with a computer simulation were compared: experimentation versus observation interactivity. Experimentation interactivity allows students to use simulations to conduct virtual experiments, whereas observation interactivity allows…

Chang, Hsin-Yi; Linn, Marcia C. – Journal of Research in Science Teaching, 2013
Powerful online visualizations can make unobservable scientific phenomena visible and improve student understanding. Instead, they often confuse or mislead students. To clarify the impact of molecular visualizations for middle school students we explored three design variations implemented in a Web-based Inquiry Science Environment (WISE) unit on…
