This complete research paper details an investigation into the influence of instructors' pedagogical knowledge on their classroom practices in the context of teaching first-year engineering courses. Background and Motivation: First-year engineering courses serve as the foundational setting in which students are introduced to the field of engineering as well as the pedagogies specific to engineering teaching and learning. These courses are pivotal in equipping students with essential knowledge and skills, setting the stage for their success in more advanced engineering topics. Understanding how instructors' pedagogical knowledge affects their teaching practices is crucial. Pedagogical knowledge encompasses a wide range of techniques to effectively manage a classroom and engage students. This includes the use of instructional strategies that cater to diverse student needs, the design of impactful and engaging lesson plans, etc. There is, however, limited research on how instructors’ pedagogical knowledge influences their classroom practices in first-year engineering courses. Hence, it seems opportune and essential to conduct additional research on engineering instructors' classroom practices. Research Question: The central question driving this research is: How does instructors' pedagogical knowledge influence their pedagogical practices for first-year engineering courses? Method: For this study, we chose the model of teacher professional knowledge and skill (TPK&S) that includes pedagogical content knowledge (PCK). The model recognizes the fundamental importance of pedagogical knowledge and contextualizes PCK within that framework, encompassing the intricate nature of teaching and learning. A descriptive case study was utilized as a methodology for this work to delve into the phenomenon. The context of the study was a first-year introductory engineering course offered at a large public research institution. This is a pilot study for an NSF-funded project (blinded for review), the study involved two instructors, Chandler and Joey (pseudonyms), chosen through purposive sampling, with varying levels of teaching experience. Data collection involved direct classroom observation using the Teaching Dimensions Observation Protocol (TDOP) and semi-structured interviews conducted after the observations. The interviews were conducted after classroom observations, allowing the researcher to explore specific findings from the observations. Results: Thematic analysis was used to categorize the data based on the constructs of the theoretical framework. The analysis revealed three major themes: (a) Instructors' topic-specific professional knowledge significantly influences their pedagogical practices. Both instructors adapt their teaching methods based on their understanding of course material and students' difficulties. (b) The interaction between instructors' personal pedagogical content knowledge (PCK) and the classroom context shapes their classroom practices. (c) Instructors' beliefs and prior knowledge act as amplifiers or filters based on the situation. They filter out their teaching practices that do not align with their beliefs and prior knowledge. Conclusion: The findings presented in this paper provide valuable insights into the complex interplay between instructors' pedagogical knowledge and their classroom practices. This work holds significant implications for current and future first-year instructors in that this paper will showcase how instructors use their understanding of the content and their students to teach, which is a critical aspect of helping students successfully integrate into engineering.

Surveying online interaction: Relating college instructor characteristics and perceptions to online instructional practices
Little is known regarding the use of, and factors related with, interaction-oriented practices. In this study we investigate instructors’ use of interaction-oriented practices in online college courses. We begin by drawing on several strands of literature to offer a person-purpose interaction framework for categorizing interaction-oriented practices. The framework’s six sub-domains integrate for whom students are interacting (instructor, student, content) with the interaction’s pedagogical purpose (academic, social, managerial). Subsequently, we examine factors that predict instructors’ use of these six domains of practices, including instructors’ characteristics and their perceptions of online learning, using a sample of (n = 126) community college instructors teaching online courses. The results show that instructors using more interaction-oriented practices consistently have greater employment status and teaching load, greater self-efficacy for using learning management systems, and greater perceived benefits of online learning for students, with subtle distinctions found across sub-domains. The findings have several implications for future research examining pedagogical behavior, as well as the design of professional development activities aimed at enhancing the use of effective online instructional practices among college instructors.

Powell, Roger (Ed.)Abstract The teaching practices used in college science classrooms have a profound influence on which students pass their courses (and continue to major in science) and which are ‘weeded out.’ Students from traditionally marginalized backgrounds have lower grades and learning gains compared to their nonmarginalized peers in courses that rely heavily on lecture and high-stakes exams. This achievement gap narrows or disappears when instructors use student-centered, evidence-based teaching practices. These teaching practices can include actions that shape our classroom environment, communicate course material, and assess student learning. In this paper, we provide a summary of the evidence supporting the use of student-centered teaching practices, followed by examples of several effective evidence-based teaching practices that can be integrated into organismal courses. Examples include faculty mindset for inclusion, teaching practices to increase student confidence and to reduce stereotype threat, increasing course structure by spreading points among several different types of activities, several active learning methods, jigsaws, Scientist Spotlights, course-based undergraduate research experiences, and inquiry-based labs. Each example is linked to supporting resources to help instructors easily implement these practices in their classrooms. The American Society of Mammalogists endeavors to be equitable and inclusive through numerous initiatives, and modifying our teaching practices can increase equity and inclusion of future mammalogists into our own classrooms.more » « less

Luo, Heng (Ed.)Online learning in higher education has been increasing for many years. This is happening across all of higher education and it is happening more specifically within STEM fields. The growth of online learning has significantly accelerated the past couple of years during the COVID-19 pandemic as colleges and universities have sought ways to continue educating students while also keeping students, faculty and staff safe. As result, many college faculty and instructors across all fields of study including STEM fields have made and continue to make the transition to teaching online for the first time. Teaching in an online environment is different from traditional classroom teaching in many ways and presents a unique set of challenges to college instructors. This study documents the development of an instrument used for instructors to self-report their instructional techniques and practices. Data from 251 instructors is also used to examine how this instrument can be used to better understand particular practices, with a focus in this study on discussion facilitation. The results align with the Community of Inquiry framework, including indicating that teaching through discussion forums involves direct contribution and/or facilitation.more » « less

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.

null (Ed.)Abstract Students are more likely to learn in college science, technology, engineering, and math (STEM) classrooms when instructors use teacher discourse moves (TDMs) that encourage student engagement and learning. However, although teaching practices are well studied, TDMs are not well understood in college STEM classrooms. In STEM courses at a minority-serving institution (MSI; n = 74), we used two classroom observation protocols to investigate teaching practices and TDMs across disciplines, instructor types, years of teaching experience, and class size. We found that instructors guide students in active learning activities, but they use authoritative discourse approaches. In addition, chemistry instructors presented more than biology instructors. Also, teaching faculty had relatively high dialogic, interactive discourse, and neither years of faculty teaching experience nor class size had an impact on teaching practices or TDMs. Our results have implications for targeted teaching professional development efforts across instructor and course characteristics to improve STEM education at MSIs.more » « less
