Breadth and depth of curriculum are important for success in science teaching and learning. Curriculum theorists recommend less breadth and more depth than overloaded, superficial science curricula. This study investigates breadth and depth in the official biology syllabi in the seventh to eighth or ninth years in four diverse jurisdictions,…

This qualitative study examines the pedagogical potential that a Cartography of Controversy (CoC) approach has in enabling secondary school students to unravel the complexity of socioscientific issues and to communicate about them. The aim was to examine the types of knowledge and the ways in which students approached uncertainty when asked to…

This study investigated the effect of explicit nature of science (NOS) instruction and explicit argumentation instruction in socioscientific and scientific contexts, on students' NOS conceptions and their argumentation skills. Undergraduate students enrolled in two sections of a science content course were assigned into two groups: Socioscientific…

We studied the emotions experienced by students during the last two years of compulsory secondary education (15 and 16 years old) when learning physics and chemistry. The objective of this piece of research was to establish different relationship between emotions felt by students and variables like the didactic methodology or the kind of science…

Despite the importance of scientific argumentation, it rarely occurs in science classrooms. Researchers have designed argumentation interventions to bridge this gap, but those efforts have limited impacts on transforming existing classroom practices. Argumentation is a linguistically social interaction. It is necessary to go beyond understanding…

The term 'experiment' is used in different ways to mean different things in school science. This study examines the meanings of 'experiment' and how they have changed in the intended chemistry curriculum (ICC) in China since the early 1950s. A mixed methodology was adopted to analyse the 11 ICC documents from a socio-historical perspective. The…

This study aims to test the effectiveness of a socio-scientific issue (SSI) based instruction through STEM-6E (engage, explore, explain, engineer, enrich, and evaluate). Controversial science topics (e.g. genetically modified organisms) in many countries, especially Indonesia, can be approached via integrated STEM education. One hundred and nine…

This multiple case study focused on the implementation of a computer-aided design (CAD) simulation to help students engage in engineering design to learn science concepts. Our findings describe three case studies that adopted the same learning design and adapted it to three different populations, settings, and classroom contexts: at the…

The purpose of this paper is to compare and contrast between two theoretical frameworks for addressing nature of science (NOS) and socioscientific issues (SSI) in school science. These frameworks are critical thinking (CT) and argumentation (AR). For the past years, the first and second authors of this paper have pursued research in this area…

Evidence of student thinking takes a variety of forms (e.g. verbal responses, gestures) and has varying degrees of visibility within classroom interactions. The purpose of this study was to characterise the nature of pre-service science teachers' (PSTs') noticing skills of different forms of evidence of student thinking using video-based…

English connects all areas of science around the world. Productive and receptive English-language skills are thus a crucial tool that schools must provide their students with in order to prepare them for higher education and professional life. The introduction of bilingual instruction of subject matter, often referred to as Content and Language…

This study explored the interplay between science teachers' pedagogical beliefs, scientific evidence, and diversity. This study adopts a sociocultural view of science that views science as a cultural way of knowing, and acknowledges that it is laden with cultural understandings, interpretations, and a language of its own. This paper reports…

This study describes multilingual students' authentic use of their first and second languages in a "translanguaging science classroom," from a sociocultural perspective. The study is ethnographic, and has followed some lessons each month in a translanguaging science classroom at a primary school for three years. The observed lessons were…

In science education research, there is a growing body of studies focusing on the role of multiple representations in pupils' learning. This study is based on a social semiotic perspective and in the analysis, there is a special focus on how the content is conveyed and how relations are created through interaction between teachers/pupils and the…

In many parts of the world, newly hired science teachers' practices are developing in a complex policy environment. However, little is known about how newly hired science teachers' practices are enacted throughout a cycle of instruction and how these practices can be influenced by macro-, meso-, and micro-policies. Knowing how policies impact…
