Reformed science curricula provide opportunities for students to engage with authentic science practices. However, teacher implementation of such curricula requires teachers to consider their role in the classroom, including realigning instructional decisions with the epistemic aims of science. Guiding newcomers in science can take place in…

Reforms such as the Next Generation Science Standards (NGSS) call for substantial change in teacher practice such as instruction that is more phenomenon-based, three-dimensional, supportive of student epistemic agency, and coherent from the student perspective. Such change requires ongoing support in the form of aligned curricular materials and…

Explicitly attending to justice in science teaching and learning is long overdue. Here, we examined the professional teacher identity development of 13 science teachers as they collaborated in networked professional learning communities (PLCs) to implement and revise a culture-setting unit focused on the science of COVID and engaging in…

This study made a preliminary attempt to conduct a needs assessment of teachers' utilization of the SSI-based approach in teaching Science by exploring Filipino teachers' awareness, perceived need, readiness, and willingness. It also aimed to determine which among the demographic profiles of the teachers had significant differences in their…

A confluence of circumstances in educational policy and teacher preparation have placed a low priority on elementary science teacher preparation. Historically, a lack of elementary science teachers' subject matter knowledge and pedagogical knowledge has negatively impacted science teaching self-efficacy, which is linked to many teacher and student…

This dissertation study uses an alternative dissertation format to deliver two separate but interrelated studies. As a whole, the dissertation is connected by a single overarching research question: "What are the characteristics of effective, meaningful, and equitable science instruction through modeling and how do teachers' pedagogical…

The purpose of the current study is to examine the effect of adapting the engineering design process to robotic coding, STEM, and the nature of science applications on teachers' self-efficacy towards engineering education and attitudes towards robotic coding. A weak experimental design with a single-group pre-test and post-test, one of the…

In response to the global crisis of type 2 diabetes prevalence, this dissertation investigated the impact of a culturally sustaining, health-centric science curriculum contextualized in type 2 diabetes. Using a case study methodology, it explored how the curriculum shaped math and science preservice teachers' (PSTs) perceptions of science and how…

Many stakeholders emphasize the importance of diverse populations' participation in the sciences, though the motivations for this vary. Some reference an economic standpoint by emphasizing the importance of either recruiting more science workers to compete in a global economy, or of individual financial success for people from historically…

Language, and thus scientific language, is essential for chemistry teaching and learning. To be able to successfully teach the scientific language of chemistry, the Chemish, (prospective) chemistry teachers need to possess pedagogical scientific language knowledge (PSLK).Thus, teacher preparation needs to focus explicitly on Chemish and its…

This study explored a middle school science teacher's curricular sensemaking in interaction with their use of an educative storyline curriculum, aligned to the Next Generation Science Standards, that was intentionally designed for more opportunities for students' scientific sensemaking. Using a phenomenological case study methodology, we examined…

The rise of global environmental issues has stressed the importance of sustainability and green chemistry teachings. Nevertheless, these topics remain largely untouched in most post-secondary organic chemistry lecture courses. This article investigates the barriers to integrating green and sustainable chemistry into organic chemistry classrooms…

Science education is shifting from a vision of students memorizing facts towards engaging in figuring out the natural world as students build ideas from their own experiences and backgrounds. This shift is hard for teachers. One way to support teachers is curriculum-based professional development, which pairs high-quality instructional materials…

Over the course of a two-year curriculum field test study that implemented a curriculum-based professional learning framework, we investigated the factors that influenced teachers' willingness and ability to implement NGSS-aligned, phenomenon-based storylines for teaching the nature of science, evolution, and climate change. Through qualitative…

Science education objectives in Brazil have evolved over time. Initially, the focus was on creating scientifically literate citizens who could relate scientific concepts to their daily lives. In 2017, the São Paulo City Curriculum for Natural Sciences was introduced to teach students scientific literacy through inquiry-based teaching methods. This…
