An introductory physics course may be run like a video game, where students have an almost unlimited number of attempts to demonstrate their competencies through a sequence of zero-penalty assessments until the end of a semester. Each checkpoint is conducted as a 10-minute, one-on-one oral interview with the instructor, and students are not…

To inform teacher education programs, it is imperative to uncover preservice teachers' (PSTs) implicit and tacit beliefs about teaching and learning science. The study of teachers' beliefs requires a range of methodological approaches to unearth their tacit beliefs. In that regard, this study used metaphor construction in conjunction with drawing…

As introductory college science courses transition from large, passive lectures to more student-centered active learning environments, additional instructional support may be needed. Peer Learning Assistants (PLAs) can aid course transformations by helping facilitate active learning and peer engagement among students in the classroom. Pedagogical…

This article aims to explore the experiences of science instructors who are active participants in the design and enactment of an interdisciplinary science course with student-centered pedagogy in a large-enrollment class. The data were collected through interviews with instructors and analyzed using the inductive thematic approach. Results show…

Redox reaction is a core concept in teaching and learning chemistry. This article explores a new method for balancing organic redox reactions that requires the balancing of both atoms and charges. The H+, O, H[subscript 2]O, and e- are used as balanced vehicles in two half reactions. A non-oxidation number approach can be applied to both molecular…

The ability to read and compose original scientific literature is critical to educating informed citizens, yet may be severely lacking in undergraduate curricula. We developed a linked course offering in fall 2017 consisting of a 16-student group taking an introductory biology course paired with a first-year composition course. The composition…

Quantitative reasoning, although included in most science courses, can be challenging to teach. In this article, we explore whether cooperative learning may help instructors teach quantitative reasoning and enhance students' understanding and learning experience. Our lesson was taught in a large introductory geoscience course. The lesson required…

A comparison of student performance in an introductory biology class that used a lecture-based approach (N = 15 classes; 462 students) with those that had a no-lecture approach (N = 9 classes; 238 students). All classes were taught by the principal researcher. In the no- lecture environment, shifts in student perceptions of science were…

Studies on the effectiveness of clickers in undergraduate chemistry courses are mixed, and there is disagreement on how to effectively leverage clickers to improve student learning performance. To fill a gap in the research, we analyzed three different teaching strategies (two involving clickers) in a General Chemistry I course over a 13-year time…

Graduate students in STEM fields undertook a 9-month training program focusing on practice-based development of active teaching methods. As instructors of record in their own senior-level courses, these trainees were observed on their independently designed classroom sessions using the COPUS classroom observation tool. Compared to a large sample…

This study contributes to the growing body of research on the role of crosscutting concepts (CCCs) in three-dimensional teaching and learning by examining the complexity of elementary preservice teachers' (PSTs) knowledge for teaching related to CCCs. The researchers used qualitative methods to analyze PSTs' responses to a questionnaire about CCCs…

With calls to reassess higher education teaching methods, active learning practices have quickly become a popular alternative to traditional lectures, especially in STEM courses that traditionally rely heavily on large-lecture formats. In this regard, active learning environments stand to better prepare students for life after college; however,…

Active learning is the new standard for teaching in higher education. As more faculty seek to expand their teaching practices by including active-learning activities that promote higher levels of learning, many are doing so in small doses by temporarily postponing traditional lectures in favor of group activities. While there is evidence…

This qualitative study compares the views about nature of science (NOS) between students enrolled in a traditional lecture and laboratory course and students in an inquiry-based class to the view of the scientists who taught the course. We administered the Views of Nature of Science Form C (VNOS-C) to identify students' views after partaking in…

A growing number of Introductory Physics for Life Sciences courses have been developed to prepare biology, premedicine, and prehealth majors for cross-disciplinary connections between physical principles and biological systems. Many students find it challenging to apply idealized algebra-based general physics to more complex biological systems. A…
