Sexual orientation continues to be an explosive issue in American classrooms. Increasing the political knowledge of students can reduce the volatility of this explosive issue by increasing tolerance toward the lesbian, gay, bisexual, and transgender community. This relationship between political knowledge and political tolerance has been…

To augment traditional lecture with instructional tools that provide options for content representation, learner engagement, and learning expression, we followed the Universal Design for Learning (UDL) principles to design and implement a learning environment for teaching and learning in large lecture classes. To this end, we incorporated four…

The impact of lecture instruction on student conceptual understanding in physics has been the subject of research for several decades. Most studies have reported disappointingly small improvements in student performance on conceptual questions despite direct instruction on the relevant topics. These results have spurred a number of attempts to…

Interactive-engagement (IE) techniques consistently enhance conceptual learning gains relative to traditional-lecture courses, but attitudinal gains typically emerge only in small, inquiry-based curricula. The current study evaluated whether a "scalable IE" curriculum--a curriculum used in a large course (~130 students per section) and…

In this paper we present results relating undergraduate student retention in science, technology, engineering, and mathematics (STEM) majors to the use of Peer Instruction (PI) in an introductory physics course at a highly selective research institution. We compare the percentages of students who switch out of a STEM major after taking a physics…

Three studies (N = 1119) were conducted to replicate and expand upon Kearney, Plax, Hays, and Ivey's seminal research on instructor misbehaviors. In study 1 (n = 233), a replication of Kearney et al.'s study revealed 43 categories of perceived instructor misbehaviors; 27 of the misbehaviors were originally identified by Kearney et al. and 16 new…

Although there has been a considerable amount of work evaluating the effects of different (non-traditional) instructional styles, inquiries into students' preferences of instructional style have been few. From 1998-2001, we surveyed introductory statistics students regarding various aspects of their class preferences, especially the teaching style…
