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…

As the 21st century progresses, we are increasingly reminded of the importance of and need for green chemistry, which also leads to the corresponding need for green chemistry education. The UC Berkeley Department of Chemistry developed a green chemistry laboratory curriculum-the "General Chemistry Green Curriculum" ("GC[superscript…

This study examines the role of Namibian secondary school science, technology, engineering and mathematics (STEM) teachers' interest in STEM education and self-efficacy in implementing STEM education in science education curricula. Furthermore, it aimed to distinguish male and female Namibian teachers' interests and self-efficacy regarding STEM…

Research on science education in Africa shows many teachers continue to use traditional lecture methods even when curriculum favours more student-centred approaches. This paper explores science teacher professional learning as a means to realise practice change at a crucial time of curriculum reform in Ghana. The study was a qualitative formative…

Adopting new instructional materials is an important way to support reform in science education, but implementation can be challenging and complex. Therefore, we conducted a contrasting case study of two middle schools implementing new curricular materials. We conducted semi-structured interviews with teachers and leaders and collected…

Seventeen years following the introduction and subsequent adoption of the Competency-Based Curriculum (CBC) in Tanzanian secondary schools, teachers continue to grapple with its implementation. This research, guided by the curriculum framework, aims to uncover the underlying issues hindering the seamless execution of CBC and explore the various…

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…

A new generation of science curriculum materials is being developed and made widely available across K-12. These materials, along with their associated professional learning, are expected to play a pivotal role in transforming science instruction to meet the vision of A Framework for K-12 Science Education and the performance expectations of the…

Most studies on fidelity focus on adherence (how much it is done), ignoring quality of delivery (how well it is done) as a measure of implementation, and are mainly quantitative in nature. In-depth qualitative studies assessing how much and how well curricula are implemented are scarce. Drawing on data from a qualitative study, this article…

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…

This study evaluated teachers' implementation of basic science curriculum content areas in junior secondary schools in Nsukka Education Zone of Enugu State, Nigeria. Four research questions were posed and three null hypotheses were formulated to guide the conduct of the study. The study employed evaluation research design (survey method). The…

Chinese 2017 General High School Physics Curriculum Standards explicitly include understanding the nature of science (NOS) as core literacy for students. History, philosophy of science, and sociology of science (HPSS) education is an important way to promote students' understanding of the nature of science. In this context, this study analyzed the…

Nurturing computational thinking (CT) in students is necessary for problem solving and important for bridging the current STEM gap, such as the American K-12 students' lagging behind in math and science standardized testing. To facilitate the integration of CT in students' and teachers' experience and insights on implementing CT into K-12…

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…
