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 is a qualitative, descriptive, and multi-case study, in which the researcher investigated the perceptions of middle school teachers who were implementing three-dimensional learning aligned with the Next Generation Science Standards (NGSS) into their instructional practices. The participants were 10 middle school teachers who worked in three…

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…

Water is one of Earth's fundamental natural systems. It is crucial to foster water literacy in today's global citizens, particularly through formal education. The purpose of this research, in parallel with a study focused on human dimensions of water systems (Mostacedo-Marasovic et al., in press), is to examine water-related K-12 standards for…

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…

In this study, an innovative scientific modeling course on concentration cells is designed: First, the demonstrations revealed examples of three different concentration cells. Then, scientific models visualizing the process and principle of cell reactions at the level of microparticulates were introduced to students. Finally, three new…

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…

In the past decade, emphasis on promoting "climate literacy" in K-16 science classrooms has increased. Teachers play a critical role in cultivating these opportunities, especially in secondary science classrooms. However, most prior climate education research has focused on students and student learning; little is known about how…
