Instructor-led presentation-based teaching mainly focuses on delivering content. Whereas student active presentations-based teaching approaches require students to take leadership in learning actions. Many teaching and learning strategies were adopted to foster active student participation during in-class learning activities. We developed the student presentation-based effective teaching (SPET) approach in 2014 to make student presentation activity the central element of learning challenging concepts. We have developed several versions to meet the need for teaching small classes (P. Tyagi, "Student Presentation Based Effective Teaching (SPET) Approach for Advanced Courses," in ASME IMECE 2016-66029, V005T06A026), large enrolment classes (P. Tyagi, "Student Presentation Based Teaching (SPET) Approach for Classes With Higher Enrolment," ASME IMECE 2018-88463, V005T07A035), and online teaching during COVID-19. (P. Tyagi, "Second Modified Student Presentation Based Effective Teaching (SPET) Method Tested in COVID-19 Affected Senior Level Mechanical Engineering Course," in ASME IMECE 2020-23615, V009T09A026). The SPET approach has successfully engaged students with varied interests and competence levels in the learning process. SPET approach has also made it possible to cover new topics such as training engineering students about positive intelligence skills to foster lifelong learning aptitude and doing engineering projects in a group setting. However, it was noted that many students who were overwhelmed with parallel academic demands in other courses and different activities were underperforming via SPET-based learning strategies.
SPET core functioning depends on the following steps:
Step 1: Provide a set of conceptual and topical questions for students to answer individually after self-education from the recommended textbook or course material,
Step-2: Group presentations are prepared by the prepared students for in-class discussion,
Step-3: Group makes a presentation in class 1-2 weeks after the day of the assignment to seek instructor feedback and to do peer discussion.
The instructor noted that students unfamiliar with the new concepts and terminologies in the SPET assignment struggled to respond to questions individually and contribute to the group discussion based on their presentation. Several motivated students who invested time in familiarizing new concepts and terminologies met or exceeded the expectations. However, a significant student population struggled. To alleviate this issue author has implemented a further improvement in SPET approach. This paper reports teaching experiments conducted in MECH 487 Photovoltaic Cells and Solar Thermal Energy System and MECH 462 Design of Energy Systems course. This improvement requires augmenting SPET with instructor-led concept familiarization discussion on the day of issuing the assignment or close to that; for this step instructor utilized exemplary student work from prior SPET-based teaching of the same course. In the survey, many students expressed their views about the improvement and reported introductory discussions were helpful and addressed several reservations and impediments students encountered. This paper will discuss the structure of the new improvement strategy and outcomes-including student feedback and comments.

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

The development of oral presentation skills requires multiple opportunities to present and receive focused feedback. In typical discipline-based and general-education courses, class time is precious, and even when oral presentations are part of a course, students may receive only one or two opportunities to present with feedback. Here we describe an approach to develop presentation skills with ultra-short, one-minute presentations followed immediately by brief, supportive, focused, public in-class instructor feedback. Feedback is offered as one positive comment (one thing I liked) and one targeted goal for improvement (one thing to work on). The short time frame maximizes the number of iterative cycles of practice, feedback, and implementation of feedback. This approach was used with students in several semester-long courses offering three to eight opportunities to present. Students took anonymous surveys immediately after the experience and again up to two and a half years post-experience. Over 95% reported that they learned a great deal about how to improve their own presentations by watching other presentations and hearing the instructor’s immediate feedback. Respondents reported lasting gains in skills, increased confidence in their public speaking abilities, and all would recommend the experience to others.more » « less

Motivation: This is a complete paper. There was a sudden shift from traditional learning to online learning in Spring 2020 with the outbreak of COVID-19. Although online learning is not a new topic of discussion, universities, faculty, and students were not prepared for this sudden change in learning. According to a recent article in ‘The Chronicle of Higher Education, “even under the best of circumstances, virtual learning requires a different, carefully crafted approach to engagement”. The Design Thinking course under study is a required freshmen level course offered in a Mid-western University. The Design Thinking course is offered in a flipped format where all the content to be learned is given to students beforehand and the in-class session is used for active discussions and hands-on learning related to the content provided at the small group level. The final learning objective of the course is a group project where student groups are expected to come up with functional prototypes to solve a real-world problem following the Design Thinking process. There were eighteen sections of the Design Thinking course offered in Spring 2020, and with the outbreak of COVID-19, a few instructors decided to offer synchronous online classes (where instructors were present online during class time and provided orientation and guidance just like a normal class) and a few others decided to offer asynchronous online classes (where orientation from the instructor was delivered asynchronous and the instructor was online during officially scheduled class time but interactions were more like office hours). Students were required to be present synchronously at the team level during the class time in a synchronous online class. In an asynchronous online class, students could be synchronous at the team level to complete their assignment any time prior to the deadline such that they could work during class time but they were not required to work at that time. Through this complete paper, we are trying to understand student learning, social presence and learner satisfaction with respect to different modes of instruction in a freshmen level Design Thinking course. Background: According to literature, synchronous online learning has advantages such as interaction, a classroom environment, and better course quality whereas asynchronous online learning has advantages such as self-controlled and self-directed learning. The disadvantages of synchronous online learning include the learning process, technology issues, and distraction. Social isolation, lack of interaction, and technology issue are a few disadvantages related to asynchronous online learning. Problem Being Addressed: There is a limited literature base investigating different modes of online instruction in a Design Thinking course. Through this paper, we are trying to understand and share the effectiveness of synchronous and asynchronous modes of instruction in an online Flipped Design Thinking Course. The results of the paper could also help in this time of pandemic by shedding light on the more effective way to teach highly active group-based classrooms for better student learning, social presence, and learner satisfaction. Method/Assessment: An end of semester survey was monitored in Spring 2020 to understand student experiences in synchronous and asynchronous Design Thinking course sections. The survey was sent to 720 students enrolled in the course in Spring 2020 and 324 students responded to the survey. Learning was measured using the survey instrument developed by Walker (2003) and the social presence and learner satisfaction was measured by the survey modified by Richardson and Swan (2003). Likert scale was used to measure survey responses. Anticipated Results: Data would be analyzed and the paper would be completed by draft paper submission. As the course under study is a flipped and active course with a significant component of group work, the anticipated results after analysis could be that one mode of instruction has higher student learning, social presence, and learner satisfaction compared to the other.more » « less

Abstract Course‐based undergraduate research experiences (CUREs) provide an efficient mechanism to provide many students with an original research project. CUREs often culminate in a capstone poster presentation, but reports on these classes usually focus on the preparation and execution of the project rather than communication of the results. This article summarizes a CURE‐associated research seminar that focuses on developing the communication and interpersonal skills required for the production and presentation of a conference poster. The class is designed to provide students with the tools and confidence for effective communication of their research. From the two class offerings to date, the 18 participating students have received five awards from 19 conference presentations.

null (Ed.)Student-to-instructor interaction is crucial in online education. Through this interaction, the instructors guide students on contents and create a learning environment that allows students to communicate between themselves. The student-to-instructor interaction is of the factors that determine student participation and satisfaction. Thus, this study uses a systematic review to discuss the strategies that instructors can use to increase student-to-instructor interaction in online courses. This study highlights four strategies, including the instructor’s participation in online courses, the feedback from an online instructor, the availability of an online instructor and timely response, and pre- and during class communications in online courses. The online instructors and instructional designers may use these strategies to improve interaction with the students. These strategies may also assist instructional designers and instructors who develop and teach hybrid or blended courses.
