This study investigated how the use of structured participation, specifically group presentation roles, supported more equitable participation in doing and learning mathematics. We analyzed videos of two lessons focused on radius, diameter, circumference, and area of circles in which students worked in small groups in a STEM project-based geometry…

This case study investigated factors that increased verbal interaction for students in group work in a ninth grade, content-based, English-as-a-Second-Language (ESL) class. Out of 11 tasks assigned to the students during the semester, four language-based and four genre-based tasks were analyzed. At the end of the study, the nature of verbal…

This study was designed to investigate the effects of cooperative…

This paper presents the results of a study of the cognitive strategies in which ninth-grade science students engaged as they used a learner-centered dynamic modeling tool (called Model-It) to make original models based upon stream ecosystem scenarios. The research questions were: (1) In what Cognitive Strategies for Modeling (analyzing, reasoning,…
