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…

This article describes some of the underlying conceptualizations that have gone into the work of the BEAR Center in the development of learning progressions. The core of all of these developments has been the construct map, which is the first building block in the BEAR Assessment System (BAS). After introducing the concept of a learning…

Alternative certification programs (ACPs) have been proposed as a viable way to address teacher shortages, yet we know little about how teacher knowledge develops within such programs. The purpose of this study was to investigate prior knowledge for teaching among students entering an ACP, comparing individuals with teaching experience to those…

To explore how elementary teachers may differ from secondary teachers in their views about NOS, a professional development experience involving explicit reflective instruction on NOS, discussions about science with scientists, and exposing the teachers to the practices, techniques, and collaborations fundamental to scientific research was…

Because the school environment has been shown to play an important role in teacher and student performance, we undertook research into the assessment of school environment, differences between female and male science teachers' perceptions of their school environments, and associations between these school environment perceptions and teachers'…

This study uses a new-to-educational-research methodology, based on the legal process, to build a case that U.S. students have been largely ignored in discussion and planning for their own, presumed futures. A variety of evidence, from two large and distinct data bases, is drawn together to show: (1) students perceive their classrooms in ways…

This study examined an interdisciplinary scientific research project to understand how graduate and undergraduate honors students learn to do science. It was found that the education of the students occurs as part of an apprenticeship. The apprenticeship takes place in research groups. In general, research groups are structured in two ways:…

Although scale has been identified as one of four major interdisciplinary themes that cut across the science domains by the American Association for the Advancement of Science (1989), we are only beginning to understand how students learn and apply scale concepts. Early research on learning scale tended to focus on perceptions of linear distances,…

We examined curricular orientations that graduate students in science and mathematics fields held as they experienced urban high-school science and mathematics classrooms. We analyzed how these educators (called Fellows) saw themselves, students, teachers, schools, education, and the sense they made of mathematics and science education in urban,…

In this theoretical article we use an interpretative study with physics undergraduates to exemplify a proposed characterization of student learning in university science in terms of fluency in disciplinary discourse. Drawing on ideas from a number of different sources in the literature, we characterize what we call disciplinary discourse as the…

The findings reported on in this manuscript emerged from a design experiment conducted at a low-income urban middle school intended to support the teacher in incorporating pedagogical practices supportive of students' everyday knowledge and practices during a 6th grade unit on food and nutrition from the LiFE curriculum. In studying the impact of…

The purpose of this investigation was to explore possible relationships between Socioscientific Issues instruction and students' development of reflective judgment. The usefulness of the Reflective Judgment Model as a tool for assessing the value of SSI is established in the parallels that can be drawn between them. Both involve ill-structured…

This study examined the influence of field placements settings with varying demographic profiles on preservice elementary teachers. Data were gathered at three points during the participants' final year in their teacher preparation program in order to chart changes over time in science teaching self-efficacy beliefs. These measures were…

In the study of science topics especially in physics students are expected to move between different modes of representation when dealing with a particular concept as any science concept can be represented in several different modes. The difficulty for students is that they are often unable to move between these multi-modal representations and…

The views on various aspects of the nature of science (NOS) of 179 novice undergraduate physics students were investigated using six open-ended, written probes. These views were consolidated within compact NOS "profiles", which were designed based on the students' responses to the probes. These profiles may be understood as sets of key…
