Remote Laboratory Exercise to Develop Micropipetting Skills

The rapid spread of COVID-19 has fundamentally transformed our educational system. The need to protect both students and instructors from exposure to viral infection has required the implementation of remote instructional models. Although this alternative delivery approach can be successfully implemented to teach the theoretical foundations of multiple disciplines, teaching technical skills poses a major challenge, particularly in various biology fields, where observation of biological safety guidelines and the high cost of analytical equipment represent major impediments for remote instruction. To overcome this problem, we have developed a laboratory exercise to teach students how to use micropipettes that can be completed remotely using materials that can be purchased at a fraction of the cost of the instructional equipment normally reserved for in-person instruction. Our evaluation of the effectiveness of this remote lab indicated that the majority of students who participated in a survey believed they attained the learning objectives and felt confident in their lab technique after completing the exercises. The simplicity, relatively low cost, and effectiveness of this approach makes it highly adaptable for other classrooms and educational settings.
