Co-design is an increasingly common process for curriculum development in science education, where teachers and researchers work together to create curricula, drawing on mutual knowledge and expertise. In efforts to understand this process, I looked at design dilemmas that occurred during design meetings and categorized the ideas that emerged in…

The excess of curriculum content is a well-known problem in high school biology. Some strategies to adjust the amount of content to the available classroom time have been proposed, but none has been widely accepted and applied. Furthermore, biology is frequently presented in high school not as an integrated science, but as a collection of…

This article deals with the study of natural sciences in non-compulsory secondary education from the end of the nineteenth century until the educational reform in 1970. We begin with a critical review of the ways in which the secondary education curriculum and textbooks of this period conveyed established knowledge about natural sciences. We then…

Science teachers struggle to implement and sustain new curricular ideas from professional development (PD) experiences. These PD opportunities are crucial for enacting real-world changes to teaching practice and address pressing global challenges, such as the teaching and learning of socioscientific topics nested in school communities.…

This study explored teachers' conceptualizations of integrated computational modeling in secondary physics by exposing twelve experienced physics teachers to programming and then analyzing interview responses. Responses revealed that teachers fell along a spectrum of disciplinary boundary-stretching mentalities. This paper presents a preliminary…

This paper describes how plate tectonics and rock genesis, two topics that are typically addressed separately in secondary Earth science classes, can be taught together as an integrated system. We define the TecRocks Reasoning Framework, developed to support student reasoning about rock formation situated in the context of plate tectonics. We also…

Over the years, the evolution of science along with technology, engineering, and mathematics has been noticeably evident while science education, on the other hand, has shown little development. The research study aimed to investigate future change initiative implementation in secondary science curricula. In addition, the purpose of the research…

Developing students' understanding of the nature of science (NOS) is seen as critical for educating scientifically literate citizens, and has emerged as an important curricular goal internationally. In Norway, a new curriculum reform has recently been implemented, intended to improve the Norwegian education in several ways. The reform aims to…

This dissertation is an extended prescription for the inclusion of social justice in high school biology (HSB) curricula. Chapter 1 is context: a review of social injustice (mainly racism) in the US, and the specious scientific justifications for it. Chapter 2 explores how three veteran teachers introduce social justice in HSB classes. A…

To promote a justice-oriented approach to science education, we formed a research-practice partnership between middle school science teachers, their students, curriculum designers, learning scientists, and experts in social justice to co-design and test an environmental justice unit for middle school instruction. We examine teacher perspectives on…

The article describes the analysis of the Italian physics curriculum documents in terms of the coverage of nature of science (NOS). NOS is not explicitly presented as part of the Italian high-school physics curriculum. The article focuses on analysing the implicit aspects of the curriculum documents. The Family Resemblance Approach (FRA) to NOS…

Variability in education systems is a given. Variability has at once positive and negative implications for the main goal of education which is accelerating learning across diverse contexts and for all learners. In this article, we explain and employ a tight-loose framing to understand the scope for variability within an education system. A…

Developing and integrating culturally aligned curriculum models which promote use of resources, such as indigenous artefacts, has been a challenge in science curriculum reforms. The study focused on the development of an integrated indigenous-pedagogical model for use in high school physics curriculum. The views of elders, teachers and learners in…

Professional development courses help teachers integrate new content knowledge into the high-school curriculum. Designing practical online courses for this purpose is challenging, particularly in emerging fields such as nanotechnology. In this study, we evaluated such a course in three complementary dimensions: (1) knowledge, (2) the complexity of…

Understanding the intellectual demands of an intended curriculum is crucial as it defines the frames for teaching and learning processes and practice during lessons. In this study, upper-secondary school chemistry curricula contents in Czechia, Finland, and Turkey were analysed, and their objectives were compared using the Revised Bloom's Taxonomy…
