This study examined the impact of microteaching experiences of preservice elementary teachers enrolled in a science teaching methods course. The microteaching lessons targeted the physical science concepts represented in the Texas Educational Agency's exam for early childhood through sixth grade teacher certification. The results of this study…

Curricular reforms in science education represent an opportunity for changes in instructional approaches with the intent of making learning and teaching more meaningful and effective. While beginning teachers may receive instruction on pedagogy aligned with adopted reforms, veteran teachers need support and development to implement instruction…

Combined three-dimensional, haptic-enabled, virtual reality (3D HE VR) systems allow students to actively engage and explore various science concepts by leveraging user-friendly and immersive interfaces. Successful implementation of these learning tools in science classrooms hinges upon teachers' perceptions of the technology's potential as a…

University laboratory science courses are typically designed to prepare science majors or those who are pursuing health related careers. These courses often do not provide the experiences necessary to improve elementary preservice teacher science teaching efficacy or attitudes and beliefs toward science. This research utilized a university science…

"A Framework for K-12 Science Education," the foundation for the Next Generation Science Standards (NGSS), identifies scientific explanation as one of the eight practices "essential for learning science" (National Research Council, 2012, p. 41). In order to design professional development so teachers can implement these new…

Representations are an effective tool that chemistry teachers choose to use in their classes to help their students understand abstract concepts. According to the model of pedagogical content knowledge (PCK), a teacher's knowledge of representations is part his/her PCK, which is shaped specifically by his/her orientation towards science teaching.…

Recent efforts to reform science education have strongly emphasized the understanding of the nature of science (NOS) as important to achieving broader scientific literacy. Despite the realization that students' understanding of NOS is important, there is a gap between research and practice. In order to teach NOS effectively in pre-college or…

Though inquiry-based teaching has long been touted as an effective pedagogy, its application by elementary classroom teachers has been problematic. Two case studies were used to investigate effective professional learning experiences for teachers and the concomitant development of scientific proficiency in children. Both case studies used a newly…
