Multiple representations, such as experimental data, schemas, tables, and graphs, are an essential resource in science teaching. However, their use in the classroom typically poses a challenge for preservice teachers. The aim of this research is to examine changes in the practices of a group of preservice teachers regarding the use of multiple…

An exploratory case study involving six grade 9 science teachers was undertaken to probe how teachers' understanding of learners' misconceptions relate to their perceptions about teaching simple circuits. The participants' understanding of documented misconceptions in electricity were explored by means of a questionnaire, while their perceptions…

There is a need for research-informed instructional approaches that promote school students' deep conceptual understanding of abstract geological concepts. Given that a type of learner-constructed stop-motion animation, 'slowmation', has been shown to offer affordances for learning in science preservice teacher education, we extended its…

In this study, students' misconceptions about the ozone layer were investigated, looking specifically at the effect internet-based media has on the formation of these misconceptions. Quantitative and qualitative research approaches were used to perform the research. As part of the quantitative portion of the research, the descriptive survey…

For decades, educators have hoped to integrate geospatial tools into K-12 classrooms but struggled with barriers of time, technology, and curriculum alignment. The authors formed a design partnership with ninth-grade science and social studies teachers in an urban high school in order to conduct teacher professional development while also…

To meet the demand for certified math and science teachers, alternative certification programs attempt to provide fast-track training and licensure of STEM-area educators (Goldhaber, Kreig, Theobald, & Brown, 2014). Teachers prepared in programs with a middle level specialization have been shown to participate in effective practices such as…

In chemical kinetics, in addition to the concepts related to kinetics, stoichiometry, chemical equilibrium and the characteristics of the reactants are often involved when comparing the rates of different reactions, making such comparisons very challenging for students at all levels, as well as for pre-service science teachers. Consequently, four…

The purpose of this study was to explore and identify the experiences that informed the development of three veteran (15+ years of teaching experience) 9th grade physics teachers' specialized knowledge, or PCK, for using representations to teach the topics of energy transformation and transfer. Through the lens of phenomenography, the study…

The focus of this First Look report is on base-year contextual data from the High School Longitudinal Study of 2009 (HSLS:09). This First Look is intended as a companion to the report, "High School Longitudinal Study of 2009 (HSLS:09): A First Look at Fall 2009 Ninth-Graders (NCES 2011327)" (ED521115), which focuses on the mathematics…
