We investigated the intersectional nature of race/racism and gender/sexism in broad scale inequities in physics student learning using a critical quantitative intersectionality. To provide transparency and create a nuanced picture of learning, we problematized the measurement of equity by using two competing operationalizations of equity:…

We present a multiple-choice test, the Montana State University Formal Reasoning Test (FORT), to assess college students' scientific reasoning ability. The test defines scientific reasoning to be equivalent to formal operational reasoning. It contains 20 questions divided evenly among five types of problems: control of variables, hypothesis…

This study introduces a new group of students to the postsecondary science agenda: "latecomers to science." Latecomers, who enter postsecondary science through alternative routes because they are missing prerequisites, are less likely to graduate than traditional science students. Challenges to latecomers' persistence are explored…

The study reported here examines the learning approaches adopted by students enrolled in introductory chemistry at a public university. To evaluate learning approaches, a group of 61 students enrolled in the course were interviewed at three time-points during the semester, specifically to ascertain how they prepared for the exams. From these…

Diverse implicit cognitive elements seem to support but also constrain reasoning in different domains. Many of these cognitive constraints can be thought of as either implicit assumptions about the nature of things or reasoning heuristics for decision-making. In this study we applied this framework to investigate college students' understanding of…

With applications of Tree of Life data becoming ever more prevalent in everyday contexts, tree thinking has emerged as a vital component of scientific literacy. This article reports a study testing the hypothesis that instruction in natural selection, which is the primary focus of US evolution education at the high school and introductory college…

Although a well-corroborated scientific theory, the theory of evolution has continued to cause dilemmas for some individuals who have not easily been able to accommodate the concepts of this theory within their cognitive culture. The reason lies in the overlap of some ideas that the theory advocates with other social, epistemological, and…

Considerable research has compared how students learn science from computer simulations with how they learn from "traditional" classes. Little research has compared how students learn science from computer simulations with how they learn from direct experience in the real environment on which the simulations are based. This study compared two…

This study aims to add to the growing research related to the implementation of non-traditional writing tasks in classrooms to encourage science literacy. A secondary reanalysis methodology was employed to review student interviews collected as a part of several individual studies during a ten year research program. This method established an…

Over the last two decades, a significant body of research has documented the nature of intuitive physics knowledge--the knowledge of the world that students bring to the learning of formal physics. However, this research has yet to document the roles played by intuitive physics knowledge in expert physics practice. In this article, I discuss three…

A composite theory of college science student note-taking strategies was derived from a periodic series of five interviews with 23 students and with other variables, including original and final versions of notes analyzed during a semester-long genetics course. This evolving composite theory was later compared with Van Meter, Yokoi, and Pressley's…

Ascertained whether chemistry instructors have a consistent preference for particular ways of idea expression by chemistry students. Comparisons of responses on a chemistry preference test were made among chemistry instructors, chemistry majors and nonscience majors. (CS)

A descriptive study conducted to identify characteristics and attitudes of college physics students as related to their perceptions of the study of physics. A questionnaire was administered to 1,108 students, of whom five percent were physics majors. Chi Square Analysis indicated students with high school physics background liked physics to a…

A theoretical model of nonscience majors' motivation to learn science was tested by surveying 369 students in a large-enrollment college science course that satisfies a core curriculum requirement. Based on a social-cognitive framework, motivation to learn science was conceptualized as having both cognitive and affective influences that foster…

Three variations of computer assisted instruction feedback were used with college astronomy students. On only one measure, a posttest, did subjects' achievement by treatments differ significantly. Significant differences in attitudes according to treatment group were not observed. (CP)
