Although decades of research attest to the importance of vocabulary teaching and learning, and recent research points to principles of effective vocabulary instruction, the small number of studies on actual classroom practice suggest that teachers continue to use the least effective approaches, often focusing on memorization of definitions.…

This paper analyses students' conceptual sense-making of two representations of protein synthesis: animations and static visualizations. Even though several studies have focused on the effect of animations versus static visualizations or support aspects that enable students to effectively benefit from animations, existing research has not yet…

This paper examines how seven teachers working in contexts of limited resources used the prescribed textbook for teaching, and the kinds of teacher-textbook relationships forged in the interactions. The study employs a sociocultural perspective to explore the processes by which teachers mobilise the affordances of the textbook to the teacher's…

Over the past decade, abroad range of policymakers, corporations, educators, and scholars in the United States have catapulted computer science (CS) education from the sidelines to the center of K-12 public education discourse. While calls for CS education are often framed in terms of national and economic competitiveness, there is a growing…

Due to the monolingual self-understanding of European nation-states, migration-induced multilingualism and the language mixing practices it triggers are not usually acknowledged as resources for learning within mainstream classrooms. The term translanguaging has recently been put forward as both a way of describing the flexible ways in which…

The low enrolment, lack of interest, exacerbated by the general poor performance in physical science in South Africa paints a gloomy picture about the status of physical science in the country. Despite the fact that there might be other factors at play, one factor which cannot be ignored is the discourse about the use of language in the science…

This paper reports on an action-research study aimed at identifying the problems and needs of a specific group of tenth graders at a school in Colombia in relation to their reading comprehension in English in order to design, partially implement, and evaluate a genre-oriented syllabus. Findings show that the explicit instruction of metacognitive…

We illustrate an analytic framework for teachers' mathematics discourse in instruction (MDI). MDI is built on three interacting components of a mathematics lesson: a sequence of examples and related tasks; accompanying talk; patterns of interaction. Together these illuminate what is made available to learn. MDI is grounded empirically in…
