Second Modified Student Presentation Based Effective Teaching (SPET) Method Tested in COVID-19 Affected Senior Level Mechanical Engineering Course

Abstract

Abstract Student presentation based effective teaching (SPET) approach was designed to engage students with different mindsets and academic preparation levels meaningfully and meet several ABET student learning outcomes. SPET method requires that students prepare themselves by guided self-study before coming to the class and make presentations to teach the whole class by (a) presenting complex concepts and systems appealingly and engagingly, and most importantly (b) serving as the discussion platform for the instructor to emphasize on complex concepts from multiple angles during different presentations. In class, SPET presentations address the conceptual questions that are assigned 1–2 weeks before the presentation day. However, the SPET approach becomes impractical for large class sizes because (i) during one class period all the students can not present, (ii) many students do not make their sincere efforts. This paper focuses on the second modification of SPET to make it practical for large classes. The method reported in this paper was tested on MECH 462 Design of Energy System Course. Unlike the first modified approach, all the students were expected to submit the response to the preassigned questions before coming to the class. In class, SPET group presentations were prepared by the group of 3–6 students, who prepared themselves by doing SPET conceptual questions individually. Students communicated with each other to make a cohesive presentation for ∼30 min. In two classes per week, we covered 5–6 group presentations to do enough discussions and repetition of the core concepts for a more in-depth understanding of the content. During the presentation, each student was evaluated for (a) their depth of understanding, (b) understanding other parts of the presentation covered by other teammates, and (c) quality of presentation and content. The student who appeared unprepared in the class group presentation were provided direct feedback and resources to address concerning areas. SPET approach was applied in the online mode during the campus shut down due to COVID-19. SPET was immensely effective and helped to complete the course learning outcomes without interruptions. SPET could be customized for the online version without any additional preparation on the instructor part.
