Inquiry-based science instruction has been advocated for decades. However, the implementation of inquiry teaching and learning in everyday classrooms is rather limited due to various factors. Previous research investigated implementations of inquiry-based teaching at the activity level with self-reported methods. However, little is known about how…

The language of science, which emphasizes reasoning about the causes and conditions of scientific phenomenon and use of visuals to convey information, can be difficult for young readers and writers without a lot of teacher scaffolding (Pappas and Varelas 2009). It is important that teachers understand these linguistic requirements to support…

This article addresses the issue of the level of complexity of practical work in science curricula and is focused on the discipline of Biology and Geology at high school. The level of complexity is seen in terms of the emphasis on and types of practical work and, most importantly, in terms of its level of conceptual demand as given by the…

This research investigated the emergent discursive modes and their pedagogical functions found in model-based inquiry (MBI) science classrooms. A sample of four high school physics classrooms was video-recorded and analysed using a newly established discourse mode analysis framework. Qualitative methods were employed to identify the most salient…

This study examines the impact of "Disaggregate Instruction" on students' science learning. "Disaggregate Instruction" is the idea that science teaching and learning can be separated into conceptual and discursive components. Using randomly assigned experimental and control groups, 49 fifth-grade students received web-based…

To test whether epistemically unproblematic ways of thinking and talking about science could be transformed during preservice teacher training, we designed a system of learning activities based on a set of "heuristics for progressive disciplinary discourse" (HPDD). The HPDD outline six design principles of learning environments where the aim is to…

The paper presents an intensive study of a micro-event aiming at the characterization of teacher's discourse from a multimodal communication perspective in a secondary school science classroom dealing with the topic of "water cycle." The research addresses the following questions: (a) What communicative modes are used by the teacher?, (b) what…

This study details an innovative approach to coordinating and enhancing multiple levels of assessment and discursive feedback around an existing multi-media curricular environment called Astronomy Village[R]. As part of a broader design-based research programme, the study analysed small group interactions in feedback activities across two design…

Summarizes content analyses of verbatim transcripts of secondary chemistry lessons. Finds that the use of words with a metacognitive and metalinguistic function was generally limited in extent and simple and colloquial in expression and that the language of the enacted curriculum did not match the terminology of the official curriculum document.…

Examines the relationship between new biology teachers' subject matter knowledge and classroom discourse, contrasting classroom discourse during laboratory investigation with discourse during other classroom activities. Data analysis suggests that knowledge and control are related but in ways unique to the communicative context of the laboratory.…

Most science instructors in classes for prospective teachers emphasize the learning of basic facts and definitions in science from textbooks and lectures. Relatively little emphasis is placed on understanding science knowledge and how to use it in daily life. Most students in these classes tend to learn science, probably without understanding,…

This paper analyzes discrepant findings from research on science teacher knowledge and classroom discourse. In new science teachers' classrooms, discourse during laboratory activities differed in important ways from discourse during other types of instruction. Furthermore, teacher subject-matter knowledge had effects that were not predicted by the…
