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…

Student-generated drawing is a useful strategy to construct students' scientific ideas. For exploring ways to support student-generated drawing, we focused on the perspective of 'Norms' -- shared behaviour patterns desirable in a community. We investigated what norms were formed and how they emerged when students made drawings to explain…

This paper describes the results of a comparative study into the approaches used by science undergraduates when solving open-ended problems. This study adopted a pseudo-grounded theory framework to analyse six case studies, one from each of the science disciplines studied. The study involved 70 participants from 5 institutions solving open-ended…

Great teaching is characterised by the specific actions a teacher takes in the classroom to bring about learning. In the context of model-based teaching (MBT), teachers' difficulty in working with students' models that are not scientifically consistent is troubling. To address this problem, the aim of this study is to identify the pedagogical…

This investigation is focused on possible links between the development of critical attitude and conceptual understanding. We conducted a fine grained analysis of five student teachers' critical and conceptual development during a one hour and a half interaction with an expert. This investigation completes a series of three previous studies…

In this case study, we explore students' communication during practical work in physics at an upper secondary school in Sweden from a sociocultural perspective. We investigate the relation between the interaction and content of students' communication and outcomes of their actions, with the purpose of finding new knowledge for informing teachers…

One important purpose of a definition is to explain the meaning of a word. Any problems associated with a definition may impede students' learning. However, research studies on the definitional problems from the perspective of physics education are limited. Physics educators may not be aware of the nature and extent of definitional problems.…

Over the past decade, the field of teacher professional learning has coalesced around core characteristics of high quality professional development experiences (e.g. Borko, Jacobs, & Koellner, 2010. Contemporary approaches to teacher professional development. In P. L. Peterson, E. Baker, & B. McGaw (Eds.), "International encyclopedia…

To gain a better understanding of teachers' beliefs about teaching, as compared with their in-reality classroom practices, case studies were constructed with four science teachers in different schools in Egypt. The main aims of this article were to provide an answer to the research question, "To what extent do science teachers' beliefs…

The case study presented in this paper examines the work of one high school chemistry teacher who has integrated guided inquiry into a yearlong, traditional curricular framework in ways that take into account the constraints and realities of her classroom. The study's findings suggest (1) the extent and frequency to which teachers can…

This paper presents the findings of the qualitative component of a combined methods research study that explores a range of individual and school factors that influence the uptake of chemistry and physics in post-compulsory study in England. The first phase involves using the National Pupil Database to provide a sampling frame to identify four…

Teaching and learning are time-dependant processes. It can be hypothesised that the content coherence during a teaching sequence is an important factor of learning. In this perspective, it is of great interest to follow the occurrences of a notion and the development of its meanings in the classroom discourse, all along the various sessions of a…

This study examines students' use of proportional reasoning in high school physics problem-solving in a West African school setting. An in-depth, constructivist, and interpretive case study was carried out with six physics students from a co-educational senior secondary school in Nigeria over a period of five months. The study aimed to elicit…

Two reasons are suggested for studying the degree of conceptual integration in student thinking. The linking of new material to existing knowledge is an important aspect of meaningful learning. It is also argued that conceptual coherence is a characteristic of scientific knowledge and a criterion used in evaluating new theories. Appreciating this…

A study on the effect of a structured problem-solving strategy on problem-solving skills and conceptual understanding of physics was undertaken with 189 students in 16 disadvantaged South African schools. This paper focuses on the development of conceptual understanding. New instruments, namely a solutions map and a conceptual index, are…
