An active-learning concurrent preparatory general chemistry course was adopted to replace a prerequisite course that lacked effectiveness in improving student outcomes. Our previous study showed that the concurrent course increased final exam performance and retention in a cohort of students. This paper studies the course modality impact of the…

Analysis of weekly peer-reviewed writing exercises in undergraduate introductory biology courses revealed that student improvement in ability to judge essays correlated with improvement in their own writing (n = 121 students). This correlation occurred across the spectrum of academic ability. The essays were scored by peers, self, and the…

We evaluate the effectiveness of companion classes designed to support at-risk first-year students in introductory biology and chemistry within the University of California system. Companion classes (co-classes) are optional classes associated with large, gateway biology and chemistry courses (parent classes) and provide three hours of instruction…

The purpose of this quantitative pretest-posttest quasi-experimental study was to examine the effect on student success rates in biology courses with laboratory components taken via distance education at a California community college. This study examined success rates for nine different courses, including 98 sections (2,299 students) taught only…

Future college environments, including those in chemistry, will entail flexible formats. The pandemic spurred appreciation of the need, and though it has largely passed, adaptability to multiple formats in the future has been a critical part of planning for a rapidly changing future. Experiences during the pandemic will guide pedagogical changes…

The abrupt shift to distance learning at the onset of the COVID-19 crisis exacerbated inequalities in California's K-12 system and added urgency to an ongoing discussion about the role of high school graduation policy in promoting equitable student outcomes. More rigorous graduation requirements, particularly in math and science, can improve…

Background: We report the results of an undergraduate course in astrophotography designed to engage non-STEM majors in the natural sciences to train future amateur astronomers and citizen scientists. Over 200,000 students enroll in introductory astronomy elective classes every year in the US alone, which will possibly be their only encounter with…

This is the technical appendix for the report, "Does Raising High School Graduation Requirements Improve Student Outcomes?" While high school graduation rates in California have increased in the past decade, nearly 40 percent of California high school graduates do not enroll in college; the disruptive impact of the pandemic has…

Community colleges are a major entry point for many students to post-secondary education, particularly for minority, first-generation, low-income, and older students. A range of factors including transfer-readiness, curricular alignment, financial barriers, and transfer guidance, influence successful transfer between two-year colleges (2YCs) and…

Previous work has looked at the relationship between high school preparation and student performance in calculus-based introductory mechanics (physics 1) courses. Here, we extend that work to look at performance in introductory calculus-based electricity and magnetism (physics 2), and we look at the significance of what college math courses have…

Despite frequent litigious interactions between science and religion, when it comes to the teaching of evolution, relatively little is known about public school teachers' understanding of the associated legal issues. The present study expands on Moore's (2004) survey by obtaining more information about respondents, surveying teachers from multiple…

We introduce a template to (i) scaffold the problem solving process for students in the physics 1 course, and (ii) serve as a generic rubric for measuring how expertlike students are in their problem solving. This template is based on empirical studies of the problem solving practices of expert scientists and engineers, unlike most existing…

In teaching newcomer students, educators must envision how to provide opportunities for language use and development through age-appropriate content instruction. This article describes a design research study, in which we developed and piloted 5th grade science units and studied the participation of two newcomer students in sense-making…

Microfluidics involves the study of the behavior of fluids at microscale, fluid manipulations, and the design of the devices that can effectively perform such manipulations. We are developing two new elective courses to include microfluidics in our curriculum at CSULB. Herein, we present the results of the first course, Microfabrication and…

Our paper describes a solution we found to a still existing need to develop mathematical modeling courses for undergraduate biology majors. Some challenges of such courses are: (i) relatively limited exposure of biology students to higher-level mathematical and computational concepts; (ii) availability of texts that can give a flavor of how…
