Practice-based approaches to teacher education should emphasize strategies that help teacher candidates centralize student thinking in instructional practice while providing a rationale for why student thinking is integral to student learning. This study describes how secondary science teacher candidates engage in tool-supported analysis of…

In the last decade, evidence in the science education literature seems to suggest that studentcentered classroom interaction appears to have effect over and above teacher-centered interaction in enhancing learning outcomes in various science subjects especially in Physics. Based on this premise, this paper examined the effects of teacher-centered…

The purpose of this study was to explore high school students' ideas regarding two theoretical scientific models, either electron cloud or sodium chloride crystal, in the context of active learning in small groups. Conversations among peers regarding these models took place during two types of active learning activities: small-group discussion and…

The study sought to investigate the role played by language in the academic performance of science students at a high school in the Free State province, South Africa who are taught through a language different from their mother tongue. The paper reports on the decisive mantle language plays in the comprehension and subsequent scholastic…

Research into the efficacy of modules featuring dynamic visualizations, case studies, and interactive learning environments is reported here. This quasi-experimental 2-year study examined the implementation of three interactive computer-based instructional modules within a curricular unit covering cellular biology concepts in an introductory high…

We examined the variation in Force and Motion Conceptual Evaluation (FMCE) preclass scores according to the type of physics class a student had in high school. This was done for students who had taken Physics 1 at a highly selective university. The majority of students had taken an Advanced Placement (AP) physics course, allowing us to examine in…

Problem-Based Learning (PBL) modules based on the topic of socio-scientific issues are behaved to be effective to improve argumentation skills. This aim of the research was to look at the effectiveness of PBL modules on the topic of socio-scientific issues, in order to empower argumentation skills for students with high and low achievements.…

This essay presents infrastructuring as a useful construct for guiding efforts to support more equitable implementation and sustainability of resources developed to support student learning in design-based research. "Infrastructuring" refers to activities that aim to redesign components, relations, and routines of schools and districts…

When sound waves are taught at the secondary level, the speed of propagation of sound is one of the most important characteristics to be analyzed. However, it is very common in textbooks that the value of sound speed in air is considered constant regardless of the experimental conditions. The great question is that since sound is a mechanical…

This paper highlights learning supports associated with genetics lessons that were implemented in a urban high school biology classroom. The supports provided access to science content for ELLs [English language learners], students with IEPs [individualized education programs], and struggling readers during an introductory unit on genetics. Due to…

Mentoring, as one of the formal teacher leadership roles, creates a space for teachers to display their leadership potential as it indirectly brings value to the school community (Ensher & Murphy, 2006). The purpose of this qualitative case study is to examine mentor teachers' perceptions whether they transfer their evolving mentoring skills…

This study investigated ways to foster positive science attitudes among newcomer first-year middle school English learners (n = 79) under two conditions: (1) "Extended Science + Extended Literacy" (planetarium-based visualisations + vocabulary + comic and trade books) and (2) "Extended Science + Literacy" (planetarium-based…

The insufficiency of teachers who teach integrative science, technology, engineering and mathematics (STEM) courses is a major challenge facing science education today. Many teachers lack adequate expertise to combine disciplines and choose effective instructional approaches. This study examines how and to what extent teachers might succeed in…

Since 2000, we have published a series of flyers highlighting various data of interest to physics faculty members and students. For example, our Fall 2015 Physics Trends flyers display the employment sectors where physics bachelor's degree recipients work, the knowledge used frequently by mid-career PhD physicists working primarily in private…

"Catalase," an enzyme found in both plant and animal cells, prevents the accumulation of toxic levels of hydrogen peroxide (H[subscript 2]O[subscript 2]) by catalyzing its decomposition to water and oxygen gas. Because this enzyme is ubiquitous, it is frequently used in high school biology laboratories to explore enzyme reactions. This…
