This study uses state-level staffing data to analyze the five-year career trajectories of all 231 first-year secondary science teachers in New Jersey who began teaching during the 2010-2011 school year. The person-position framework for studying teacher retention is introduced in this analysis, and the authors present a case for the importance of…

Argumentation as a scientific practice has largely been examined along an epistemic and/or dialogic perspective in science education research. Both perspectives have sidelined the use of real material objects that are indispensable for scientists to construct arguments about the natural world. To address this gap, this article investigates how…

There are international concerns about decreasing rates of chemistry degree enrolment. This article seeks to understand students' reasons for not/choosing to pursue a chemistry degree, drawing on (i) open-ended survey responses from a sample of 506 students in England aged 21-22 who had studied advanced level ("A level") chemistry at age…

In recent years, many studies have researched the impact of teachers' professional knowledge on teaching quality. Those findings are still ambiguous providing unclear evidence for supporting teacher education programs that aim at developing professional knowledge. In this study, we followed a new approach and used a "performance test" to…

The goal of this exploratory study was to analyze how beginning prospective secondary school teachers approached the analysis of student written responses to formative assessment probes. We sought to identify what elements of students' written work were noticed, what types of inferences of student understanding were built, and what these noticed…

We analyze longitudinal data from students who spent their academic careers in North Carolina (NC) public secondary schools and attended NC public universities to investigate the importance of high school racial composition and opportunities to learn in secondary school for choosing a science, technology, engineering, and mathematics (STEM) major.…

The article argues that science assessment should change from an item-driven to a construct-driven practice and pay more attention to disciplinary scientific reasoning. It investigates assessment scales developed from a novel theoretical rationale, describing scientific reasoning as three fundamental practices (hypothesizing, experimenting, and…

A framework for teaching scientific inquiry in upper secondary chemistry education was constructed in a design research consisting of two research cycles. First, in a pilot study a hypothetical framework was enriched in collaboration with five chemistry teachers. Second, a main study in this community of teachers and researchers was conducted on…

Assessments associated with learning progressions are designed to provide diagnostic information about the level and nature of student understanding. Valid interpretations of such diagnoses are only possible when students consistently express the ideas associated with a single learning progression level. Latent class analysis was employed to…

We describe efforts toward the development of a hypothetical learning progression (HLP) for the growth of grade 7-14 students' models of the structure, behavior and properties of matter, as it relates to nanoscale science and engineering (NSE). This multi-dimensional HLP, based on empirical research and standards documents, describes how students…

This article provides an extended, comprehensive example of how teachers, schools, districts, and external factors (e.g., parental pressure and policy mandates) shape curriculum research in the U.S. It retrospectively examines how three different middle school curriculum units were implemented and scaled-up in a large, diverse school system. The…

Reports on a study conducted to identify cognitive factors associated with differences in predicting problem-solving success among high school biology students. Results indicate that successful prediction depends on several factors, including a subject's procedural and declarative knowledge, stage of cognitive development, and experience in…

Investigates the conceptions and representations of light propagation, image formation, and sight typical to preinstruction learners (N=139). Findings indicate that preinstructional students display some familiarity with optical systems, light propagation, and illumination patterns and have not developed a consistent descriptive and explanatory…

Examines which of the warrants of authority, coherence, and empirical evidence were invoked by grade 8 science classroom participants in their daily interactions, and whether these were linked to particular teaching referents. Results indicate that when the teacher embraced a context exposure referent at the expense of constructivism, the warrant…

Duplicates an analysis conducted 20 years ago on physics enrollment in New York State in an attempt to verify the exploratory percentage enrollment in physics path analysis model using data gathered for the 1990-91 school year. Findings indicate that there has been no change in the set of variables related to physics enrollment. (Author/JRH)
