Although there has been some success with programmes that aim to increase STEM involvement by women and underserved minorities, science educators continue to seek ways to promote students' interest in STEM. This study builds on social cognitive career theory (SCCT) and the theory of enclothed cognition to assess the impact of wearing lab coats on…

Although policy makers have made gains in getting students to consider future careers in science, women and many minorities are still underrepresented in science fields. Here we describe research conducted with fifth grade students in a rural area of the southeastern U.S. that examined students' concepts of scientists' characteristics. The results…

As one of the authors was warning the fifth-grade class about protecting clothes from spills in the lab, one student commented that his pants wouldn't stain because they were covered with some "nano stuff." The class tossed water on the pants and watched it bead up and roll off "like magic." The class's interest was piqued, and the questions…

Describes the effects of ability-paired student interactions on achievement as fifth graders (n=83) worked on laboratory activities relating to balance. Results revealed that low ability student achievement is greater, they speak more words, exhibit less distracting behavior, and move blocks on the lever less when they are paired with a partner of…

This study describes the effects of ability-paired student interactions on achievement as fifth graders (ten-year-olds) worked on laboratory activities relating to balance. Achievement gains were assessed (n=83) by analysis of pre/posttest differences on the Lever Concept Test. Audio recordings and field notes (n=30) were analyzed for the…

Investigates high-achieving fifth-grade students' achievement gains and conceptual reorganization on convection. Features an instructional sequence of three dyadic inquiry investigations related to convection currents as well as pre- and post-assessment consisting of a multiple-choice test, a card sorting task, construction of a concept map, and…

Examines the relationships and development of communities of concepts related to heat and convection among fifth grade students. Discusses the influence of familial and cultural experiences on conceptual development as well as the extent to which competing phenomena affect the development of new conceptual understandings. (Contains 49 references.)…

A study described the social interactions of ability-grouped dyads as they construct knowledge of the scientific concept of balance to elucidate the relationship between interactions and conceptual growth. The verbal and nonverbal behaviors of 30 fifth-grade students were recorded as they completed three activities related to balance and levers.…
