We validate the Measure of Acceptance of the Theory of Evolution (MATE) on undergraduate students using the Rasch model and utilize the MATE to explore qualitatively how students express their acceptance of evolution. At least 24 studies have used the MATE, most with the assumption that it is unidimensional. However, we found that the MATE is best…

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…

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…

This quasi-experimental, mixed methods study examined the transfer of a well-established pedagogical strategy, Peer-Led Team Learning (PLTL), to an online workshop environment (cPLTL) in a general chemistry course at a research university in the Midwest. The null hypothesis guiding the study was that no substantive differences would emerge between…

The importance of "size and scale" in nanoscience and engineering has been recognized by both scientists and science educators. A solid understanding of this concept is key to the learning of nanoscience. Students, however, have been reported to have considerable difficulty grasping this concept; yet little is known regarding their state…

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…

This study investigated the representations of a select group of scientists (n = 10) in a sample of Canadian high school and college textbooks. Drawing on semiotic and cultural-historical activity theoretical frameworks, we conducted two analyses. A coarse-grained, quantitative analysis of the prevalence and structure of these representations…

This study exemplifies how faculty members can develop instruments to assess affective responses of students to the specific features of the courses they teach. Means for assessing three types of affective responses are demonstrated: (a) student attitudes towards courses with differing instructional objectives and methodologies, (b) student…

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…

Identifies relationships between college nonscience majors' (N=1,014 in 24 chemistry classes) expectations of the scientific enterprise and (1) nonacademic background factors, (2) academic background factors, and (3) components of science courses in which the students were enrolled. (CS)

Some early results are reported of a study to examine trends of student evaluations in college level physics courses. Higher ratings were consistently given for higher level courses. (PS)

Examined some of the factors that affect the academic choices that students make and the consequences of those choices for later participation in science. Results (obtained from questionnaires completed by 302 students) show that women rated their science ability lower than men, although they performed better in high school science. (JN)

Examines statistical correlations between six student traits and five measures of course success for 103 college students enrolled in an audio-tutorial introductory chemistry course. Among the conclusions was that the best predictors of success are the measures of prior achievement, notably grade-point average. (MLH)

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…
