This project produced an online astronomy course based on the free, online OpenStax textbook. When this project was conceived, about a year before the COVID-19 pandemic, the authors had no idea that in a short period of time, most college and university classes would be online. This abrupt change in modalities of courses, from traditional,…

This study compares synchronous versus asynchronous online teaching in an introductory calculus-based physics class. Like many schools, our institution transitioned to online teaching during the COVID-19 pandemic. We held optional synchronous online sessions during the original class time, and approximately half of our students were regular…

Representation use is a critical skill for learning, problem solving, and communicating in science, especially in physics where multiple representations often scaffold the understanding of a phenomenon. University Modeling Instruction, which is an active-learning, research-based introductory physics curriculum centered on students' use of…

Laboratory courses are often designed using step-by-step protocols which encourage students to conduct experiments without thinking about what they are doing or why they are doing it. Such course design limits the growth of our students as scientists and can make it more difficult for a student to transition to the expectations of a research…

The number of women studying STEM careers and pursuing graduate degrees has not changed in the last decade (National Student Clearinghouse Research Center, 2015; Science & Engineering Degree Attainment: 2004-2014). Most prior research to explain this problem has focused on the topics of identity, access, pedagogy, and choice (Brotman &…

Evolutionary theory is central to the biological sciences, and to critical aspects of everyday life, and yet a significant proportion of Americans reject evolution. Our study sets out to examine the role of a second year college general education course in affecting students' acceptance of evolution. We report three years of data using the Measure…

This study aimed to explore the gender differences of participants' learning results, perceptions and gaming behaviors related to an energy quiz game with both single-player and multiplayer game modes simultaneously provided for participants. Seventy-four ninth-grade students played the game in six classes over three weeks. The pretest-posttest on…

We describe the design and implementation of an undergraduate peer mentor program that can overlay an existing general chemistry laboratory and is designed to improve STEM student retention. For the first four freshman cohorts going through the program, year-to-year retention improved by a four-year average of 20% for students in peer-mentored…

The Conceptual Survey of Electricity and Magnetism (CSEM) has been used to assess student understanding of introductory concepts of electricity and magnetism because many of the items on the CSEM have strong distractor choices which correspond to students' alternate conceptions. Instruction is unlikely to be effective if instructors do not know…

We developed a multi-week laboratory in which college-level introductory biology students investigate Mendel's stem length phenotype in peas. Students collect, analyze and interpret convergent evidence from molecular and physiological techniques. In weeks 1 and 2, students treat control and experimental plants with Gibberellic Acid (GA) to…

We have investigated the efficacy of on-line, multimedia learning modules (MLMs) as preparation for in-class, lecture-based tutorials in electromagnetism in a physics course for natural science majors (biology and marine science). Specifically, we report the results of a multiple-group pre/post-test research design comparing two groups receiving…

National reports have called for the introduction of research experiences throughout the undergraduate curriculum, but practical implementation at many institutions faces challenges associated with sustainability, cost, and large student populations. We describe a novel course-based undergraduate research experience (CURE) that introduces…

This research aims to compare the effects of Jigsaw technique from the cooperative learning methods and traditional learning method on laboratory material recognition and usage skills of students in General Physics Lab-I Course. This study was conducted with 63 students who took general physics laboratory-I course in the department of science…

We implemented a laboratory curriculum reform to teach foundational concepts in chemistry, particularly those concepts related to healthcare, in a chemistry course for prenursing students. Here, we discuss the reform, exploring how students built upon understandings gained in lab and correlating lab learning to course outcomes. We further discuss…

Understanding the nature of science (NOS) is one of the challenging objectives in science education due, in part, to the complex relationship between religion and science. This study examines how NOS teaching affects the perception of the NOS amongst religious, as compared to secular, students. The participants included 205 religious and secular…
