Perception of competence achievement and students' satisfaction using virtual laboratories in Medical Biochemistry course: Lessons from the COVID-19 pandemic

After the COVID-19 pandemic, there was an increasing demand for remote learning and an expansion in the substitution of traditional practical sessions with lab-based virtual tools. This study aimed to assess the effectiveness of virtual labs in practicing biochemical experiments and to examine the student's feedback regarding this tool. Virtual and traditional labs training were compared in teaching qualitative analysis of proteins and carbohydrates experiments for first-year medical students. Students' achievements were assessed, and their satisfaction regarding virtual labs was estimated using a questionnaire. A total of 633 students were enrolled in the study. There was a significant increase in the average scores of students performing the virtual lab of protein analysis compared with those trained in a real lab and those who watched videos explaining the experiment (p < 0.001). The opposite was noticed in the qualitative analysis of carbohydrates with significantly high grades of students trained conventionally compared with those who practiced with virtual labs (p < 0.001). Students' feedback rates on the virtual labs were high (>70% satisfaction rate). Most students believed virtual labs were supported with a clear explanation, yet they thought it did not give a realistic experience. Students accepted virtual labs, but they still prefer using them as preparatory to classic labs. In conclusion, virtual labs can offer good laboratory practice in the Medical Biochemistry course. Their impact on students' learning might be increased if selected cautiously and implemented properly in the curriculum.
