Purpose: PowerPoint presentations have changed representations of knowledge. They represent a social transformation process of communication which is also reflected in social-studies classrooms. Thus, it is important to examine not only how students hold presentations but also to explore the construction of knowledge through presentations: What…

Secondary literacy instruction often happens "to" adolescents rather than "with" them. To disrupt this trend, we collaborated with 12th-grade "literacy mentors" to reimagine literacy teaching and learning with 10th-grade mentees in a public high school classroom. We used positioning theory as an analytic tool to (a)…

This paper evaluates the development of new cultural theories utilizing video-based analysis. For this purpose, a multi-methods research design, combining videographies, group discussions and surveys, was applied. A video sequence showing a clip of a 10th grade class at Ramja Public School in Pusa Road in Delhi provides the basis for a discussion…

Nowadays, outreach labs are important informal learning environments in science education. After summarizing research to goals outreach labs focus on, we describe our evidence-based gene technology lab as a model of a research-driven outreach program. Evaluation-based optimizations of hands-on teaching based on cognitive load theory (additional…

In a six-week literature circle unit in a tenth-grade classroom, one group of students discussed Dorothy Allison's novel "Bastard out of Carolina." By criteria frequently used to judge the quality of discussion, this literature circle was successful. However, several key moments are highlighted that point to the limits of literature circles as…

This paper reports on a study into the untutored ability of Grade 10 students to engage in argumentation about the interpretation of experimental data, and the effect of unsupported small group discussions on this ability. In this study, argumentation intends to promote critical thinking. The sample includes 266 students from five South African…

The aim of the current research is to characterize the conceptual flow processes occurring in whole-class dialogic discussions with a high level of interanimation; in the present case, of a high-school class learning about image creation on plane mirrors. Using detailed chains of interaction and conceptual flow discourse maps--both developed for…

The main goal of the present study is to investigate empirically the effects of Asynchronic Learning Network (ALN) embedded within metacognitive instruction (META) on two components of metacognitive awareness: Knowledge about Cognition (KC) and Regulation of Cognition (RC). Participants were 202 tenth grade students: 102 students who studied under…

Questions about the suitability of cognitively-oriented instructional approaches for students of different academic levels are frequently raised by teachers and researchers. This study examined student participation in knowledge-building discourse in two implementations of a short inquiry unit focusing on environmental problems. Participants in…
