Knowing how science teachers develop their professional knowledge has been a challenge. One potential way to determine the professional knowledge of teachers is through videos. In the study described here, the authors recruited 60 elementary and secondary science teachers, showed them one of two 10-min videos, and recorded and analyzed their…

Advanced placement (AP) physics performance is an important metric for examining precollege student preparation for post-secondary study. The present study examined potential predictors of AP Physics 1 performance including gender, teacher, and school-level characteristics. A theoretical framework proposed teacher preparation and experiential…

In this article, we describe the case of "Keri," a fifth-grade teacher who had completed an Elementary Mathematics Specialist (EMS) certification program. Drawn from a larger study investigating the knowledge, beliefs, and practices of EMSs, Keri's case was unique in that she was teaching mathematics to four classes in a departmentalized…

Integrated STEM education within North America has become a popular pedagogy; however, teachers identify challenges that arise when planning for and implementing integrated STEM education. These challenges may threaten STEM teachers' capacity to balance disciplinary and integrated learning, a core feature of effective STEM education. The purpose…

Logarithms are notorious for being a difficult concept to understand and teach. Research suggests that learners can be supported in understanding logarithms by making connections between mathematics and science concepts such as pH. This study investigated how an integrated chemistry and mathematics lesson impacted 29 teachers' understanding of the…

The Next Generation Science Standards emphasizes the inclusion of engineering practices throughout the K-12 science curriculum. Therefore, elementary educators need to be knowledgeable about engineering and engineering careers so that they can expose their students to engineering. The purpose of this study was to examine the effect of engineering…

With the introduction of single-sex classroom settings in coeducational public schools, there is an ongoing debate as to whether single-sex education may reduce or reinforce traditional stereotypes and gender roles. In this article we present findings from a study that investigated the extent to which mathematics is perceived as a gendered domain…

As teachers design lessons, their considerations influence their instructional practice. Researchers have found that teachers often have preconceived ideas about gender and large-scale assessment data show gender differences in mathematics achievement. Given the differences in gender performance, and recognizing the role that gender considerations…

Before we can effectively apply specific interventions through professional development, it is important to determine what is occurring in our high school physics classrooms. This study investigated common professional practices in physics teaching among a representative sample group of schools and teachers from a diverse, geographically large…

Educational reformation has proceeded slowly despite the many calls to improve science and mathematics for our students. The acronym STEM (science, technology, engineering, and mathematics) has been adopted by numerous programs as an important focus for renewed global competitiveness for the United States, but conceptions of what STEM entails…

This study of students competing in the 2009 Massachusetts State Science & Engineering Fair investigates the role gender played in students' participation, choice of science field, award of prizes, and mentioning inspiring teachers. Females made up 62 percent of the participants and were more likely to enter projects in biology and in…

Intense focus on student achievement results in mathematics and science has brought about claims that K-12 teachers should be better prepared to teach basic concepts in these disciplines. The focus on teachers' mathematics and science content knowledge has been met by efforts to increase teacher knowledge through funded national initiatives…

The study examined relationships among key domains of science instruction with English language learning (ELL) students based on teachers' perceptions of their classroom practices (i.e., what they think they do) and actual classroom practices (i.e., what they are observed doing). The four domains under investigation included: (1) teachers'…

In this study, the characteristics of teachers that motivate their implementation of reform curriculum, and the factors that influence the teachers' success in implementing the curriculum are investigated. In particular, teachers' internal struggles, frustrations, collegiality, and classroom successes during the implementation of the reform…

Although popular media often provides negative images of mathematicians, we contend that mathematics classroom practices can also contribute to students' images of mathematicians. In this study, we examined eight mathematics teachers' framings of mathematicians in their classrooms. Here, we analyze classroom observations to explore some of the…
