1. Learning Outcomes and Insights from a Chocolate-based Undergraduate Materials Science Course and Other Topical Outreach Activities

   https://doi.org/10.1557/adv.2017.635

   ABSTRACT Those involved in STEM outreach, from elementary schools through undergraduate students, all use varying teaching styles in an effort to instruct and inspire students. However, it is incredibly difficult to gauge or compare learning outcomes from new teaching techniques in situ. In this work, we describe the outcomes of a new undergraduate mini-course at Johns Hopkins University, Chocolate: An Introduction to Materials Science. In particular, the outcomes of teaching binary phase diagrams in this course using topical food examples were compared to the outcomes of the same instructor teaching a similar control group of students using standard textbook examples, reducing a number of confounding factors and allowing us to objectively analyze the benefits of using an atypical, popular approach to teach a standard subject. Results indicate that the students in the Chocolate course were not only more excited and engaged in the lecture, but they had identical or potentially greater learning gains than the control group.

2. Instructional decision making in a gateway Quantitative Reasoning course

   Many educators and professional organizations recommend Quantitative Reasoning as the best entry-level postsecondary mathematics course for non-STEM majors. However, novice and veteran instructors who have no prior experience in teaching a QR course often express their ignorance of the content to choose for this course, the instruction to offer students, and the assessments to measure student learning. We conducted a case study to investigate the initial implementation of an entry-level university quantitative reasoning course during fall semester, 2018. The participants were the course instructor and students. We examined the instructor’s motives and actions and the students’ responses to the course. The instructor had no prior experience teaching a QR course but did have 15 years of experience teaching student-centered mathematics. Data included course artifacts, class observations, an instructor interview, and students’ written reflections. Because this was a new course—and to adapt to student needs—the instructor employed his instructional autonomy and remained flexible in designing and enacting the course content, instruction, and assessment. His instructional decision making and flexible approach helped the instructor tailor the learning activities and teaching practices to the needs and interests of the students. The students generally appreciated and benefited from this approach, enjoyed the course, and provided positive remarks about the instructors’ practices.

3. The Effects of Teaching Modality on Collaborative Learning: A Controlled Study

   This Research Full Paper presents our findings of studying the effects of teaching modality on collaborative learning by comparing data from two sections of a Database Systems course offered simultaneously, with one offered fully face-to-face in a classroom setting while the other is offered online through a flipped-classroom model. Both sections utilized a collaborative learning approach where students work on group activities for part of the class meeting. Since the two sections were almost identical except for the teaching modality, we are provided with a unique opportunity to study the effect of teaching modalities on collaborative learning. As part of this study, we analyze four crucial data sources: 1) student performance data from the grade book 2) student performance data from the online learning management platform 3) an end-of-semester survey given by the instructor and 4) an end-of-semester survey given by the university. We extract insights on the impact of teaching modalities on collaborative learning in order to identify factors that can enhance collaborative learning. We also study the effect of teaching modalities on students’ performance. We visualize our findings to differentiate between the two modalities, and draw on the strengths of each section to establish recommendations for the instructors for course improvement efforts.

4. Randomized controlled trial of 1st semester linked course learning communities for STEM retention

   Kling, Thomas; Ramsey, Laura (June 2024, https://aaas-iuse.org/)

   Linked-course learning communities are a widely used strategy to promote connections between students and support student retention. This grant project created linked-course learning communities at Bridgewater State University, a public University in southeastern Massachusetts. The communities paired a central 3-credit seminar focused on one or more United Nations Sustainable Development Goal (UN SDG) with the student’s first science class and appropriate mathematics class. This choice was inspired by social psychology research literature showing that students traditionally underrepresented in STEM often value, and look for, the social relevance of science and benefit from structures that provide a more communal, as opposed to individualistic, orientation in their studies.

5. Peer-led team learning for introductory biology: relationships between peer-leader relatability, perceived role model status, and the potential influences of these variables on student learning gains

   https://doi.org/10.1186/s43031-020-00020-9  

   Winterton, Christina I.; Dunk, Ryan D.; Wiles, J. R. (February 2020, Disciplinary and Interdisciplinary Science Education Research)

   Student-instructor interactions have an influence on student achievement and perceptions of learning. In college and university settings, large introductory STEM courses are increasingly including Peer-Led Team Learning (PLTL), an evidence-based technique associated with improved student achievement, recruitment, and retention in STEM fields, especially for underserved populations. Within this technique, peer leaders hold a unique position in a student’s education. Peer leaders have relevant experience in that they have had recent success in the courses in which they facilitate student learning, yet, compared to student-faculty or student-teaching assistant relationships, there is minimal imbalance of authority or power. Students might find their peer leaders to be more relatable than faculty or graduate teaching assistants, and may even consider them to be role models. We explored students’ perceptions of peer leader relatability and role model status in relation to students’ achievement and their perceived learning gains in the context of an introductory biology course with an associated PLTL program. The final course grades and self-assessed learning gains of PLTL students who felt they related to their peer leader were compared to those who did not. We also compared final course grades and self-assessed learning gains between PLTL students who viewed their peer leader as a role model versus those who did not. Self-reported learning gains were significantly higher for students who relate to their peer leader, as well as for students who viewed their peer leaders as a role model. There is some support that this trend is stronger for STEM majors versus those who are not enrolled in a STEM program, though the interaction is not significant. Significant differences in overall course grade were only observed between students who reported that they related to their peer leader versus those who did not relate to their peer leader.
