Schmidt, Jonas; Huber, Tim; Mu¨ssig, Jo¨rg – Journal of Chemical Education, 2022
The knowledge of the mechanical properties of polymers and other materials is essential for several tasks in the field of materials science, like component design and material development. The tensile test is one method of determining many of the material's most defining mechanical characteristics. However, the teaching of laboratory experiments…

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.…

Elcoro, Mirari; Trundle, Melissa B. – International Journal for the Scholarship of Teaching and Learning, 2013
We examined the preference of undergraduate students for a live or a virtual rat when learning about concepts of operant conditioning. Students were provided with the opportunity to directly compare a virtual and a live rat in a supplemental exercise for Learning courses. We argue that the design of teaching exercises should involve a systematic…
