A hands-on activity to teach the osmosis phenomenon

AN ALTERNATIVE METHOD TO TEACH THE OSMOSIS PHENOMENON

This study proposes a hands-on activity as an experimental alternative method to teach biomedical engineering students the os-mosis phenomenon. The students were guided along a learning path that involved their participation in the design and construc-tion of a test device used to measure osmoticflow rate. Thereafter, an experiment was conducted with the test device. Thestudents analyzed the obtained experimental values, which provided them with evidence of the functionality of the device. Inaddition, they were provided with the opportunity to suggest improvements and to propose alternatives to expand the use ofthe device to test other transport phenomena such as diffusion. Moreover, a student perception survey was conducted, and theresults showed that this proposed plan allows for a better understanding of the phenomenon and stimulates the curiosity of stu-dents, improving the receptiveness, key in the learning process of the students.
