Engineering education is facing major challenges as it seeks to provide necessary and robust practical experience for all its undergraduate students The limitation of resources (capital and operational), the increasing number of engineering students and the need to provide safe, up-to-date laboratory experiences have become global issues Although the use of virtual laboratories (VLs) can provide some relief, within the engineering curriculum further pedagogical research is still needed In this article, we investigate student perceptions of their learning experience that occurred using a commercial VL (Labster) for fermentation to replace the usual physical laboratory We use Kolb's experiential learning cycle for the theoretical framework to examine the different stages of active learning and Bloom's taxonomy to illustrate the levels of learning that occurred Using a mixed-methods methodology, multiple sources were used to analyze the students' experiences In general, the simulation experience conducted as a VL was well-received by undergraduate students and they appreciated the use of technology to shorten the required time for the experiment However, there were limitations of the commercial model, related to the learning framework and learning objectives Nevertheless, our findings suggest the VL is well-suited to be used as a supplement or as a preparatory tool but also has merit when the laboratory is unable to be accessed, for example, with the global pandemic COVID-19, which has had a devastating influence on educational institutions worldwide, closing many of them down and requiring students and staff to self-isolate
