Pedagogical content knowledge (PCK) refers to the content-specific knowledge that teachers use to promote students' learning of specific subject matter. PCK comprises multiple knowledge components that interact with each other when enacted in teachers' instructional practices. For many years, researchers lacked a robust methodological approach to…

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,…

The aim of this study is to investigate students' meaning-making of multiple visual representations of epigenetics at different levels of biological organisation, and to discern what visual aspects of the multiple visual representations might influence students' reasoning. Adopting an exploratory approach, we analysed how students made meaning of…

This study investigates the effects of process-oriented guided inquiry learning (POGIL) on the academic performance and science process skills of Grade 10 Filipino students in science. Specifically, this study aimed to (1) determine and compare the level of academic performance of students when exposed to POGIL and non-POGIL and (2) assess the…

Professional Vision (PV) has been used in teacher education to interpret novice teachers' learning in various educational contexts. To date, research has conceptualized this framework largely from a cognitive perspective of learning, overlooking the affordances of taking a sociocultural perspective. This theoretical paper aims to articulate the…

This case study examined teachers' on-the-fly formative assessment conversations, that is, how teachers collect information from students' thinking and use that information to support their learning during teacher-student interactions. Previous studies have typically analysed whole-class discussions on the level of speaking turns, and have…

This paper analyses Australian secondary science teachers' perceptions of their pedagogy and students' classroom engagement based on the Science Capital Teaching Approach (SCTA). Previous research studies related to the idea of teaching to enhance the science capital of secondary students mainly employed qualitative methods to collect data from…

Scientific inquiry has been advocated as a common curriculum goal in school science education in South Africa, and also throughout the world. In South Africa, the introduction of inquiry-based instruction in a reformed science curriculum has met with serious challenges, such as the under-preparedness of in-service teachers. The purpose of this…

In a traditional lecturing environment, students possess limited agency in accepting or rejecting information provided by teachers. A higher level of student agency involves opportunities and actively identifying uncertainties and collaborating with peers to deepen understanding within the classroom community. Teachers play a crucial role in…

Science is part of the educational curricula, and its teaching is the responsibility of teachers. Since 2000, scholars from The Organisation for Economic Co-operation (OECD) countries have been tested in science by the Programme for International Student Assessment (PISA), despite the diversity in national higher education systems. This requires a…

This study aimed to examine the influence of a culturally adapted and context-specific technique of instruction called the culturo-techno-contextual approach (CTCA) on lowering student anxiety and fostering meaningful learning in difficult biology concepts. A quasi-experimental pre-test and post-test non-equivalent group design was used for this…

This qualitative study examined teachers' science teaching orientations (STO) and their purposes for integrating the history of science (HOS) into their teaching using newly developed instructional materials. The HOS may be used as an effective instructional tool for achieving scientific literacy; however, science teachers utilise it in various…

Understanding the nature of science (NOS) is an important goal of science education, and textbooks are a key factor in shaping students' conceptions of NOS. In this study, we analysed NOS represented in middle school chemistry textbooks in the Chinese mainland. The selected materials were three most commonly adopted textbook series, which were…

One issue facing teachers who implement model-based instruction within the school system is the tight curricular schedule. The 'lesson objective tension' calls for investigations to address instructional issues such as how to organise modelling-based instruction at the curriculum level which is across multiple units. We investigated the effect of…

This research integrates context-based learning and modelling. It presents a teaching-learning sequence (TLS) about the dissolution of gases in liquids using carbonated drinks as the context. The impact of the TLS is analysed in a longitudinal short-term study involving two groups of learners aged 13-14 years old (n=53). The results led us to…
