Shen, Jian; Deng, Shubo; Wu, Jing – Journal of Chemical Education, 2022
The undergraduates in the major of Environmental Science and Environmental Engineering frequently ignored the importance of identifying pollution sources for water environment monitoring and knew little about the techniques of identifying pollution sources. Thus, a laboratory experiment which focused on pollution sources identification in a water…

Chen, Kai; Zhou, Jingming; Lin, Jiayi; Yang, Jing; Xiang, Jiamin; Ling, Yizhou – Journal of Chemical Education, 2021
The topic of chemistry safety was included at the margins of traditional chemistry education in China. In order to understand the concerns of the safety issues based on the new chemistry curriculum in the mainland China secondary school, this study analyzed old and new secondary chemistry curriculum standards via the Natural Language Processing…

Koul, Anjni; Mehrotra, Alka – School Science Review, 2018
To improve the quality of education, it is important for teachers to have an understanding of action research. Action research is 'learning by doing', which involves identifying a problem, looking for a plan to resolve it, observing how successful it is and, if not satisfied, trying again. Action research helps educators to be more effective in…

Shi, Wei-Zhao; Ma, Liping; Wang, Jingying – Journal of Baltic Science Education, 2020
Students' epistemologies of experimental physics refer to how they understand the role of experimentation as well as the experimental operation and design and communication of results in physics. This research aimed to find whether students in inquiry-based physics laboratory activities show more expert-like epistemologies of experimental physics…

Zhang, Mu-Hua; Su, Chien-Yuan; Li, Yan; Li, Yan-Yan – Australasian Journal of Educational Technology, 2020
Recently, virtual and remote labs (VRLs) have been developed to support students in conducting experiments in engineering and science education. However, little is known about the students' intentions to continue using VRLs and their satisfaction with the experience. This study proposed an extended model embedded within the expectation…

Xu, Xinhua; Wu, Meifen; Wang, Xiaogang; Yang, Yangyiwei; Shi, Xiang; Wang, Guoping – Journal of Chemical Education, 2016
The reaction process of copper-aluminum displacement in agar gel was observed at the microscopic level with a stereomicroscope; pine-like branches of copper crystals growing from aluminum surface into gel at a constant rate were observed. Students were asked to make hypotheses on the pattern formation and design new research approaches to prove…

Wang, Yue; Xu, Xinhua; Wu, Meifen; Hu, Huikang; Wang, Xiaogang – Journal of Chemical Education, 2015
Scanning electron microscopy (SEM) was introduced into undergraduate physical chemistry laboratory curriculum to help students observe the phase composition and morphology characteristics of tin-lead alloys and thus further their understanding of binary alloy phase diagrams. The students were captivated by this visual analysis method, which…
