As models of how students' thinking may change over time, learning progressions (LPs) have been considered as supports for teachers' classroom assessment practices. However, like all models, LPs provide simplified representations of complex phenomena. One key simplification is the characterization of student thinking using levels--that is, the…

This longitudinal case study investigates how one science teachers' conceptions change in one domain (assessment of science learning) but not in another (understanding the pedagogical implications of student diversity) over a period of 10 years that includes a university teacher education program and nine subsequent years of experience of…

Most science curricular reform efforts are designed by administrators or science education experts. It is less common for teachers to work collaboratively across disciplines to create, implement, and disseminate an integrated STEM curriculum developed for noncollege-bound students that ended up being popular across student populations at the…

Whereas science teachers often express initial enthusiasm about the student-centered, reform-oriented instructional strategies they encounter in professional development (PD), they rarely adopt them in practice. One possible obstacle is a mismatch between these strategies and teachers' beliefs about what is possible and desirable in their…

Using findings from a 4-year research and development effort, we propose an updated model of sheltered instruction for science classrooms that leverages the opportunities provided by the Next Generation Science Standards (NGSS) to better support multilingual learners in middle and high school science. Using data from teacher implementation logs…

Scholars argue that bridging students' backgrounds with canonical science is necessary for students of color by reducing incongruences between home and school and increasing the authenticity of science learning. However, science teachers often struggle with enacting culturally responsive pedagogies (CRP). This paper utilizes data from classroom…

Following the argument that an explicit focus on teacher thinking is an important outcome for professional development (Capps, Crawford, & Costas, 2012; Desimone, 2009), the research presented here examines the impact of one form of professional development, Research Experiences for Teachers (RETs), has in shaping teachers' beliefs and…

Science education researchers increasingly focus on the use of controversial science topics in the classroom to prepare students to make personal and societal decisions about these issues. However, researchers infrequently investigate the diverse ways in which students learn about controversial science topics outside the classroom, and how these…

This paper reports a study that explores Egyptian science teachers' views on religion and science within the context of Islam. It also highlights an ontological and epistemological consideration of these views, particularly the ways through which Egyptian Muslim teachers understand such a relationship with reference to the Qur'anic/Islamic…

The teaching of science is a complex process, involving the use of multiple modalities. This paper illustrates the potential of a multimodal semiotics discourse analysis framework to illuminate meaning-making possibilities during the teaching of a science concept. A multimodal semiotics analytical framework is developed and used to (1) analyze the…

Previous literature has documented how teachers perceive both advantages and disadvantages associated with standards-based reform. These teacher perceptions may be connected to classroom practices in terms of the extent to which standards are utilized by individual teachers. The purpose of this study was to identify how secondary science teachers…

Although there have been numerous studies that indicate the benefits of teachers and students working with scientists, there is little research that documents scientists' views of science education, science teacher preparation, and the goals of science education. Furthermore, little is known about how scientists' views of science education may…

Many researchers and teacher educators propose that reflection is an important way teachers can think about changing their views and practices. The hierarchical constructs used to describe reflection, however, are often interpreted in ways that promote reflection as a "tool" teachers use to elevate their views and practices toward ideal "end…
