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:…

Two approaches to the content of thermodynamics were used in an introductory college physics course: traditional organization and organization based on Ausubel's learning theory. The influence of these organizations on engineering student's (N=58) cognitive structure was investigated using a word association test analyzed through hierarchical…

Homework gives students an opportunity to practice important college-level physics skills. A switch to Web-based homework alters the nature of feedback received, potentially changing the pedagogical benefit. Calculus- and algebra-based introductory physics students enrolled in large paired lecture sections at a public university completed homework…

This case study focused on a preservice teachers' (Morgan) efforts to explicitly emphasize nature of science (NOS) elements in her first-grade internship classroom. The study assessed the change in first grade students' views of the inferential, tentative, and creative NOS as a result of the explicit instruction. Morgan held appropriate views of…

The purpose of this study was to investigate Ethiopian physics undergraduate students' conceptual change in the concepts of electric potential and energy (EPE) and electromagnetic induction (EMI). A quasi-experimental design was used to study the effect of cognitive perturbation using physics interactive simulations (CPS) in relation to cognitive…

This study investigated interactions between student traits and treatments. Engineering and physics majors were enrolled in either a lecture-recitation-laboratory section, or an audio-tutorial section of an introductory physics course. No significant differences were found between the two groups, but an interaction was found between two traits…

Students at the junior high school (JHS) level often cannot use their knowledge of physics for explaining and predicting phenomena. We claim that this difficulty stems from the fact that explanations are multi-step reasoning tasks, and students often lack the qualitative problem-solving strategies needed to guide them. This article describes a new…

This study aimed to investigate the comparative value of experimenting with physical manipulatives (PM) in a sequential combination with virtual manipulatives (VM), with the use of PM preceding the use of VM, and of experimenting with PM alone, with respect to changes in students' conceptual understanding in the domain of heat and temperature. A…

Compares changes in attitudes toward science and open-mindedness in treatment and nontreatment groups of preservice elementary teachers enrolled in an inquiry-oriented methods course and an expository freshman physics course, respectively. Concludes that course design effects a difference in attitude and open-mindedness. (CS)

This study aims at giving a systematic description of the cognitive activities involved in teaching physics. The most important conclusion from the results is that teaching by experienced university teachers can be described in terms of instruction processes belonging to the two-dimensional model described in this study. (PR)

Presents data on student performance in a competency-based, multiple-opportunity format physics course, indicating that costs are related to character of examination questions and comprehensional modes of students. Compares costs for single/multiple trial formats, showing that multiple-trial opportunity has lower costs and a higher yield of…

Study concludes that professors focused on development of intellectual skills, assuming that students had a specific physics vocabulary. Students, however, were aware of their own limitations and suggested that professors should take nothing for granted. Students considered that, to be a good teacher, a professor should know the perspective of the…

The experimental/analogy group scored significantly higher than the control group on a posttest question that required the definition of diffusion (n=77 community college students). Hypothetico-deductive reasoning skill was significantly related to correct application of the diffusion concept to a change from the misapplication of the polarity and…

This study investigates the understanding of 18 first-year undergraduate students when simultaneously presented with two contrasting dynamical situations: the idealized (without air resistance) and real-world cases of balls being dropped or thrown. Previous work has shown that getting students to recognize flaws in their mental models helps them…
