Project-based Learning-A Novel Approach to Teach Biosensors and Transducers Course for Engineering Students

Bio Sensors and Transducers (BST) is a fundamental subject that provides principles of operations of sensors used in biomedical applications, and transducers are the devices that transmit the signals from the biosensors to the diagnosing equipment. BST is the introductory course in Bachelors of Biomedical Engineering (BME). BST interconnects biosensors and transducers in such a way that the signals are transmitted to the receiving equipment. Given the above, this paper describes the teaching and in-depth learning of BST in the classroom sessions which makes the students challenge and solve real-time problems practically, more effectively and efficiently. At the end of each unit, a practical assignment is given and executed by the students in the BST laboratories. These improve critical thinking, analyzing, interpreting, and solving techniques for students. The primary objective of this paper is to enhance the in-depth learning of the BST course by critical analysis, utilizing creative ideas, novel thinking of extension of existing technologies, and practicing laboratory experiments. The outcomes of this course are analyzed by internal assessment tests, periodical assignments, results of the laboratory experiments, seminars, and quiz programs. With the help of Bloom's taxonomy, the assessment test questions were ranked and the results are investigated for the improvement of intellectual thinking of students on the contents of the course.

The academic transformation of students is measured by using both course outcomes and student feedback. This approach helped the students to improve their understanding of the subject.
