Internationally, second level curriculum policy for STEM education is concentrating its efforts on promoting curriculum-making pedagogies, with enquiry-based teaching and learning at the forefront of this change. Policy aspirations have not translated well into practice, evidenced by science practical lessons consistently being delivered as…

Integrated STEM education within North America has become a popular pedagogy; however, teachers identify challenges that arise when planning for and implementing integrated STEM education. These challenges may threaten STEM teachers' capacity to balance disciplinary and integrated learning, a core feature of effective STEM education. The purpose…

As part of curriculum reforms, models and modelling (MoMo) are playing an increasingly prominent role in science education. Through a questionnaire study, this paper investigates lower secondary school teachers' (n = 246) perceived practices of, rationales behind, and possibilities for working with MoMo in the context of the revised science…

Following professional development (PD), implementation of contemporary topics into high school biology requires teachers to make critical decisions regarding integration of novel content into existing course scope and sequence. Often exciting topics, such as neuroscience, do not perfectly align with standards. Despite commitment to enacting what…

This qualitative case study investigated why and how a teacher used his agency in curriculum-making. The study uses in-depth interviews, classroom observation, and teaching artefacts to understand the socio-cultural perspective on the interplay among agency, resources, schema, and structure. It finds that in this case, teacher agency was triggered…

There are vital topics in science teaching and learning which are mentioned frequently in the literature. Specialists advocate their importance in the curriculum as well as science teachers stress their saliency. Inservice education might well assist new and veteran teachers in knowledge and skills. The very best science lessons and units of…

Background: Professional learning communities are increasingly recognized for their significance in building teachers' competencies for educational reform. However, the knowledge development cycle of technological pedagogical content knowledge (TPACK) through multiple professional learning communities is not well researched. Purpose: This…

In this article, I describe the processes involved in designing and carrying out a case study project. The case study focuses on a science teacher, Donald, who was undertaking an inquiry-based curriculum change to an advanced chemistry course in a specialized science, technology, engineering, and mathematics school. I describe the groundwork…

This study provides an example of a systematic professional development project designed to build capacity for the teaching of nature of science and scientific inquiry, while not sacrificing the learning of more traditional science subject matter. Specifically, this project examined the impact of a 5-year professional development project on K-12…

This article presents an in-depth study supporting the Scientist in the Classroom Partnership (SCP) program as a model of effective professional development (PD) for K-12 teachers. The goal of this study was to determine the core and structural features of the SCP program necessary for effective teacher PD. The SCP partners a classroom teacher…

This case study focuses on teachers' professional development in NanoScience and nanoTechnology (NST). In the context of a Community of Learners (CoL), in-service teachers in collaboration with science education researchers, nanoscience researchers and experts from science museums, developed a teaching module. This module integrates NST topics…

Background: Teachers can have a significant impact on student interest and learning in science, technology, engineering, and math (STEM) subjects and careers. Teacher self-efficacy can also significantly affect student learning. Researchers investigated the effects of teacher professional development and integrated STEM curriculum development on…

Over the past few decades, a growing body of evidence demonstrates that students learn best in engaging, interactive, collaborative, and inquiry-based environments. However, most college science classes are still taught with traditional methods suggesting the existing selection of research-based instructional materials has not widely transformed…

This paper illustrates the use of simulation-based performance assessment (PA) methodology in a recent study of eighth-grade students' understanding of physical science concepts. A set of four simulation-based PA tasks were iteratively developed to assess student understanding of an array of physical science concepts, including net force,…

Science education in the US entered a period of reform in 2011 with the development and implementation of the Next Generation Science Standards (NGSS). The NGSS have subsequently been adopted in 18 states. School districts within these states are in the process of adjusting science curricula to align with the academic expectations described by the…
