Biology teachers' reflections on the benefits and challenges of using scanning electron microscopes in a biology classroom

Calls have been made to give K-12 teachers and students access to current methods used in biological research, including advanced microscopy. The scanning electron microscope (SEM) is a powerful tool that can be used for either remote or onsite inquiry experiences for students. To use this microscope in a way that promotes students' understanding of biological concepts, teachers should be informed about its capabilities, benefits and limitations as an instructional tool. Therefore, we introduced SEM to in-service biology teachers through a teacher-training workshop where they experienced activities using the SEM. We then assessed their views on the possible benefits and challenges of the SEM in high-school biology class, and particularly while teaching the relationships between structure and function. The participants' insights are described and discussed here, shedding light on what biology teachers should take into consideration while planning and engaging their students in activities using the SEM. © ISLS.
