Jichao Xue; Jiaxin Liu; Qingshu Yuan; Zhengwei Yao; Jin Xu; Zhigeng Pan – Education and Information Technologies, 2025
To optimize learning experience and improve learning performance, current virtual experimental systems usually assist students with stepwise guidance before operations and feedback after them. However, stepwise and excessive guidance can lead to student overreliance, while late feedback cannot avoid potential errors during experimental learning.…

Faith E. Jacobsen – Journal of Chemical Education, 2023
The goal of this study was to assess student's laboratory technique learning during online laboratories in response to the transition online caused by COVID-19. From Summer 2020 through Fall 2021 our General Chemistry 1 laboratories were completely online using at-home lab kits and 3 h weekly web conference sessions. Starting Spring 2021 select…

Stieff, Mike; Werner, Stephanie M.; Fink, Bill; Meador, Dianne – Journal of Chemical Education, 2018
This paper examines the effectiveness of adding an online component to the general chemistry laboratory in which students view prelaboratory instructional materials through online videos prior to completing general chemistry laboratory activities. Using a quasi-experimental design, we compared the performance of 1089 general chemistry students who…

Lindsay, E. D.; Murray, S.; Liu, D. K.; Lowe, D. B.; Bright, C. G. – European Journal of Engineering Education, 2009
Remote and virtual laboratories are increasingly prevalent alternatives to the face-to-face laboratory experience; however, the question of their learning outcomes is yet to be fully investigated. There are many presumptions regarding the effectiveness of these approaches; foremost amongst these assumptions is that the experience must be "real" to…
