1. Impacts of a geoscience research experience for undergraduates program on broadening participation in scientific research and increasing retention in STEM

   Rice, A; Loikith, P; Yuan, A; Murry, A (December 2022, American Geophysical Union)

   Recent reviews of science, technology, engineering, and mathematics (STEM) education conclude that engagement of undergraduate students in research generally broadens future participation in research and increased retention in STEM. Towards the goal of investing in a sustained and diverse atmospheric science research community, the Center for Climate and Aerosol Research (CCAR) at Portland State University (PSU) introduced a Research Experience for Undergraduates (REU) program in 2014 with the objective of providing atmospheric science summer research experiences to promising students in STEM disciplines from rural Northwest and Native American communities who would be unlikely to be otherwise exposed to such opportunities at their home institution. The PSU CCAR REU site is focused on student research in areas of atmospheric chemistry, physics, air quality, meteorology and climate change. For 10 weeks, students conduct research with an expert faculty mentor and participate in activities such as a short courses, faculty research seminars, and hands-on group workshops; academic professional and career development workshops; journal club activities; and opportunities for travel for student presentations at scientific conferences; and social activities. The program ends with a paper based on their summer research, which is presented via poster and oral presentations during our concluding CCAR symposium. Evaluation data from seven cohorts (2014-2021) of the CCAR REU (N = 70) was used to explore how science identity had changed over the course of the program, as well as what predicted positive increases in science identity. Change was assessed using paired-sample t-tests. To explore the predictors of change, we ran an exploratory stepwise regression where the difference score in science identity items from pre- to post-program was predicted by similar changes in knowledge, intrinsic motivation, extrinsic motivation, and career aspirations, demographic characteristics (e.g., age, gender), and mid-program satisfaction and met expectations. In this presentation, we present these findings along with supportive qualitative analyses and discuss their implications for undergraduate research programs in geoscience fields.

   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.

3. Implementation of a Standalone, Industry-centered Technical Communications Course in a Mechanical Engineering Undergraduate Program

   The ability to communicate technical information in written, graphical, and verbal formats is an essential durable skill for engineering students to develop as undergraduates and carry forward into the workplace. Employers have highlighted recent graduates’ inability to formulate tight, cohesive arguments for their engineering decisions, as well as difficulties adjusting their communication style for different audiences. Even though accreditation outcomes now explicitly include durable skills, such as “an ability to communicate effectively with a range of audiences,” prior research suggests that the field is still far from meeting industry expectations for proficiency in the varying modalities and styles of workplace communication. Laboratory courses are frequently relied upon to teach or reinforce writing and presentation skills. There are two major issues with this approach. First, in lab classes, the communication method is typically narrowly focused on reports that simulate writing for hypothesis-driven research projects, which fail to align with the design-based and project management aspects of professional engineering workloads. Second, lab courses that heavily emphasize technical communications frequently do so at the expense of technical knowledge, that is, the engineering concepts involved with the laboratory experiment. Many students already view communication skills as “soft” in comparison to technical knowledge; and this attitude affects their performance and retention. In this paper, we present the design and implementation of a stand-alone technical communications course that was specifically created for first-year mechanical engineering students and centered on multiple, industry-aligned modalities of communication. There are two major writing assignments in the course, both of which are open-ended “technical briefs” that involve background research, data analysis, and justification of an engineering decision for a design firm. For these major assignments, students individually submit a draft and receive detailed feedback for improvement before submitting the final versions. These two major assignments are scaffolded with weekly individual assignments that give students experience with a range of communication skills and modalities, e.g., using a reference manager and composing professional emails. To gauge the effectiveness of this stand-alone course in improving students’ technical communication skills, we conducted pre- and post-course surveys of all students enrolled in the course in 2023 (n=147), and we also tracked improvements in technical writing from draft to final form via established rubrics. Students demonstrated gains in self-efficacy for nearly all technical communication skills covered in the course as well as improved self-efficacy in different communication modalities, e.g., email, slide presentations, and executive summaries. The results of this evaluation suggest that a stand-alone, industry-centered technical communications course builds student competency with communication strategies used in the workplace. Future work will focus on whether students are able to transfer these skills into latter courses and ultimately their careers.

4. A Quantitative Analysis of When Students Choose to Grade Questions on Computerized Exams with Multiple Attempts

   https://doi.org/10.1145/3386527.3406740

   In this paper, we study a computerized exam system that allows students to attempt the same question multiple times. This system permits students either to receive feedback on their submitted answer immediately or to defer the feedback and grade questions in bulk. An analysis of student behavior in three courses across two semesters found similar student behaviors across courses and student groups. We found that only a small minority of students used the deferred feedback option. A clustering analysis that considered both when students chose to receive feedback and either to immediately retry incorrect problems or to attempt other unfinished problems identified four main student strategies. These strategies were correlated to statistically significant differences in exam scores, but it was not clear if some strategies improved outcomes or if stronger students tended to prefer certain strategies.

5. PREPARATORY DISCUSSION AND PROJECT AUGMENTED STUDENT LEARNING VIA STUDENT PRESENTATION BASED EFFECTIVE TEACHING (SPET) APPROACH

   Pawan, Tyagi (January 2022, EDUlearn 2022, 14th annual International Conference on Education and New Learning Technologies Palma de Mallorca (Spain). 4th - 6th of July, 2022.)

   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.
