Evidence has shown that facilitating student-centered learning (SCL) in STEM classrooms enhances student learning and satisfaction [1]–[3]. However, despite increased support from educational and government bodies to incorporate SCL practices [1], minimal changes have been made in undergraduate STEM curriculum [4]. Faculty often teach as they were taught, relying heavily on traditional lecture-based teaching to disseminate knowledge [4]. Though some faculty express the desire to improve their teaching strategies, they feel limited by a lack of time, training, and incentives [4], [5]. To maximize student learning while minimizing instructor effort to change content, courses can be designed to incorporate simpler, less time-consuming SCL strategies that still have a positive impact on student experience.
In this paper, we present one example of utilizing a variety of simple SCL strategies throughout the design and implementation of a 4-week long module. This module focused on introductory tissue engineering concepts and was designed to help students learn foundational knowledge within the field as well as develop critical technical skills. Further, the module sought to develop important professional skills such as problem-solving, teamwork, and communication. During module design and implementation, evidence-based SCL teaching strategies were applied to ensure students developed important knowledge and skills within the short timeframe. Lectures featured discussion-based active learning exercises to encourage student engagement and peer collaboration [6]–[8]. The module was designed using a situated perspective, acknowledging that knowing is inseparable from doing [9], and therefore each week, the material taught in the two lecture sessions was directly applied to that week’s lab to reinforce students’ conceptual knowledge through hands-on activities and experimental outcomes. Additionally, the majority of assignments served as formative assessments to motivate student performance while providing instructors with feedback to identify misconceptions and make real-time module improvements [10]–[12].
Students anonymously responded to pre- and post-module surveys, which focused on topics such as student motivation for enrolling in the module, module expectations, and prior experience. Students were also surveyed for student satisfaction, learning gains, and graduate student teaching team (GSTT) performance. Data suggests a high level of student satisfaction, as most students’ expectations were met, and often exceeded. Students reported developing a deeper understanding of the field of tissue engineering and learning many of the targeted basic lab skills. In addition to hands-on skills, students gained confidence to participate in research and an appreciation for interacting with and learning from peers. Finally, responses with respect to GSTT performance indicated a perceived emphasis on a learner-centered and knowledge/community-centered approaches over assessment-centeredness [13].
Overall, student feedback indicated that SCL teaching strategies can enhance student learning outcomes and experience, even over the short timeframe of this module. Student recommendations for module improvement focused primarily on modifying the lecture content and laboratory component of the module, and not on changing the teaching strategies employed. The success of this module exemplifies how instructors can implement similar strategies to increase student engagement and encourage in-depth discussions without drastically increasing instructor effort to re-format course content.

Limited or complete? Teaching and learning conceptions and instructional environments fostered by STEM teaching versus research faculty
An instructor’s conceptions of teaching and learning contribute to the establishment of learning environments that may benefit or hinder student learning. Previous studies have defined the continuum of teaching and learning conceptions, ranging from limited to complete, as well as the instructional practices that they help to inform (instructor-centered to student-centered), and the corresponding learning environments that these conceptions and practices establish, ranging from traditional to student-centered. Using the case of one STEM department at a research-intensive, minority serving institution, we explored faculty’s conceptions of teaching and learning and their resulting instructional practices, as well as uncovered their perspectives on the intradepartmental faculty interactions related to teaching. The study participants were drawn from both teaching-focused (called Professors of Teaching, PoTs) and traditional research (whom we call Research Professors, RPs) tenure-track faculty lines to identify whether differences existed amongst these two populations. We used interviews to explore faculty conceptions and analyzed syllabi to unveil how these conceptions shape instructional environments.
Overall, PoTs exhibited complete conceptions of teaching and learning that emphasized student ownership of learning, whereas RPs possessed intermediate conceptions that focused more on transmitting knowledge and helping students prepare for subsequent courses. While both PoTs and RPs self-reported the use of active learning pedagogies, RPs were more likely to also highlight the importance of traditional lecture. The syllabi analysis revealed that PoTs enacted more student-centered practices in their classrooms compared to RPs. PoTs appeared to be more intentionally available to support students outside of class and encouraged student collaboration, while RPs focused more on the timeliness of assessments and enforcing more instructor-centered approaches in their courses. Finally, the data indicated that RPs recognized PoTs as individuals who were influential on their own teaching conceptions and practices.
Our findings suggest that departments should consider leveraging instructional experts who also possess a disciplinary background (PoTs) to improve their educational programs, both due to their student-centered impacts on the classroom environment and positive influence on their colleagues (RPs). This work also highlights the need for higher education institutions to offer appropriate professional development resources to enable faculty to reflect on their teaching and learning conceptions, aid in their pedagogical evolution, and guide the implementation of these conceptions into practice.

Abstract Background The University of California system has a novel tenure-track education-focused faculty position called Lecturer with Security of Employment (working titles: Teaching Professor or Professor of Teaching). We focus on the potential difference in implementation of active-learning strategies by faculty type, including tenure-track education-focused faculty, tenure-track research-focused faculty, and non-tenure-track lecturers. In addition, we consider other instructor characteristics (faculty rank, years of teaching, and gender) and classroom characteristics (campus, discipline, and class size). We use a robust clustering algorithm to determine the number of clusters, identify instructors using active learning, and to understand the instructor and classroom characteristics in relation to the adoption of active-learning strategies.
Results We observed 125 science, technology, engineering, and mathematics (STEM) undergraduate courses at three University of California campuses using the Classroom Observation Protocol for Undergraduate STEM to examine active-learning strategies implemented in the classroom. Tenure-track education-focused faculty are more likely to teach with active-learning strategies compared to tenure-track research-focused faculty. Instructor and classroom characteristics that are also related to active learning include campus, discipline, and class size. The campus with initiatives and programs to support undergraduate STEM education is more likely to have instructors who adopt active-learning strategies. There is no difference in instructors in the Biological Sciences, Engineering, or Information and Computer Sciences disciplines who teach actively. However, instructors in the Physical Sciences are less likely to teach actively. Smaller class sizes also tend to have instructors who teach more actively.
Conclusions The novel tenure-track education-focused faculty position within the University of California system represents a formal structure that results in higher adoption of active-learning strategies in undergraduate STEM education. Campus context and evolving expectations of the position (faculty rank) contribute to the symbols related to learning and teaching that correlate with differential implementation of active learning.

Abstract Background Belonging is a fundamental human motivation associated with a wide range of positive psychological, educational, social, and job outcomes. Frequent and predominantly conflict‐free interactions within a stable, relational framework of caring are required to facilitate belonging.
Purpose The goal of this study was to understand if and how emergency remote teaching (ERT) used during the COVID‐19 pandemic changed the ways in which instructional support and interactions were linked to belonging among engineering students.
Methodology/Approach This study used survey data from a cross‐sectional dataset at a single large institution comprised of sophomore to senior‐level students (
n = 1485) enrolled in engineering courses between 2016 and 2021. Hierarchical linear modeling (HLM) was used to study relationships among instructional support, instructor interactions, and belonging.Findings/Conclusions HLM models of ERT and traditional learning differed dramatically. In traditional classroom learning, race, interactions with faculty and teaching assistants (TAs), and instructional support were important factors in belonging. In ERT, certain motivations to study engineering (altruism, desire to build things) had nuanced associations with belonging, while race and interactions with faculty and TAs became largely irrelevant. Most concerning, faculty interactions in traditional learning were negatively associated with belonging.
Implications Rather than returning to pre‐pandemic traditional learning, a hybrid model that offers a more level playing field for marginalized students to find belonging in the classroom is recommended. In developing such models, faculty must take special care to avoid having a potentially negative impact on student belonging.

This is a research study that investigates the range of conceptions of prototyping in engineering design courses through exploring the conceptions and implementations from the instructors’ perspective. Prototyping is certainly an activity central to engineering design. The context of prototyping to support engineering education and practice has a range of implementations in an undergraduate engineering curriculum, from first-year engineering to capstone engineering design experiences. Understanding faculty conceptions’ of the reason, purpose, and place of prototyping can help illustrate how teaching and learning of the engineering design process is realistically implemented across a curriculum and how students are prepared for work practice. We seek to understand, and consequently improve, engineering design teaching and learning, through transformations of practice that are based on engineering education research. In this exploratory study, we interviewed three faculty members who teach engineering design in project-based learning courses across the curriculum of an undergraduate engineering program. This builds on related work done by the authors that previously investigated undergraduate engineering students’ conceptions of prototyping activities and process. With our instructor participants, a similar interview protocol was followed through semi-structured qualitative interviews. Data analysis has been undertaken through an emerging thematic analysis of these interview transcripts. Early findings characterize the focus on teaching the design process; the kind of feedback that the educators provide on students’ prototypes; students’ behavior while working on design projects; and educators’ perspectives on the design course. Understanding faculty conceptions with students’ conceptions of prototyping can shed light on the efficacy of using prototyping as an authentic experience in design teaching and learning. In project-based learning courses, particular issues of authenticity and assessment are under consideration, especially across the curriculum. More specifically, “proportions of problems” inform “problem solving” as one of the key characteristics in design thinking, teaching and learning. More attention to prototyping as part of the study of problem-solving processes can be useful to enhance understanding of the impact of instructional design. Challenges for teaching engineering design exist, and may be due to difficulties in framing design problems, recognizing what expertise students possess, and assessing their expertise to help them reach their goals, all at an appropriate place and ambiguity with student learning goals. Initial findings show that prototyping activities can help students become more reflective on their design. Scaffolded activities in prototyping can support self-regulated learning by students. The range of support and facilities, such as campus makerspaces, may also help students and instructors alike develop industry-ready engineering students.more » « less

Abstract Supporting changes in undergraduate science, technology, engineering, and mathematics (STEM) instruction requires an understanding of the relationship between STEM instructors' conceptions and practices. In this study, the authors used the Teacher‐Centered Systematic Reform (TCSR) model as a framework to understand how instructors' conceptions are related to their instructional practices. This multiple methods study included interviews and classroom observations of 22 STEM instructors. We used qualitative methods to describe instructors' conceptions of how students learn and quantitative methods, including a hierarchical cluster analysis, to analyze the types of relationships that exist between their conceptions and practices. Results indicated instructors had a wide range of conceptions that exist along a continuum from teacher‐centered to student‐centered. While many faculty members perceived student‐centered practices as valuable, they conceptualized these practices in different ways. Instructors implemented a wide range of instructional practices, and these practices varied independently of conceptions. We identified three distinct clusters of participants based on the relationships between instructors' conceptions and practices: congruent lecturers, congruent active learning facilitators, and incongruent lecturers. In the first two clusters, instructors' conceptions were aligned with their instructional practices. However, incongruent lecturers thought that students learn through active learning approaches but primarily lectured in their courses. Instructors in this group described several personal and contextual factors that influenced the relationship between their conceptions and practices. The results include an in‐depth portrayal of one participant in each cluster. We found that student‐centered conceptions may be necessary but are not sufficient for instructors to implement active learning. Implications focus on instructional and institutional change efforts. To promote instructional change most effectively, it is important to address each component of the TCSR model, including personal and contextual factors. A focus on conceptions and practices alone may not sufficiently support faculty members in overcoming barriers that limit active learning instruction.
