This paper studies the scaffolding of conceptual development for children aged 4-5 years old during a science project at a Swedish preschool. It specifically examines how bodily knowledge and language are used in interaction, and how conceptual knowledge can be scaffolded with the use of external tools and artefacts. The science project was…

This study examined 6th graders' use of the VoiceThread app as part of a science inquiry project on photosynthesis and carbon dioxide emissions in terms of their ability to engage in causal reasoning and their use of the affordances of multimodality, collaboration, interactivity, and connectivity. Students employed multimodal production using…

This article describes learner and tutor reports of a learning network that formed during the completion of investigative projects on a residential field course. Staff and students recorded project-related interactions, who they were with and how long they lasted over four phases during the field course. An enquiry based learning format challenged…

We examine the science and pedagogy behind a historical approach to the professional development of pre-college science (primarily biology) teachers. Our intention is to reach professional scientists, who, as a group, are uniquely qualified to provide experience and insights essential to this approach. The underlying research for this article has…

This paper describes the simultaneous effects, including interactions, of two controlled instructional management variables and two student aptitudes on student achievement using a class-means model. Management variables were time allocated for learning with two levels of 45 and 50 class periods, and source of direction with three levels of…

Results of 11 studies of classroom practices used with activity-based elementary science programs were combined quantitatively using a composite category system. One finding reported is that teachers trained in program use spent less time talking and more on activities than untrained teachers using the programs. (Author/JM)
