In this study, the effects of teacher assistants' collaborative learning and learners' self-assessment on self-regulation and academic achievement at high levels have been investigated. Collaborative learning teaching method (Jigsaw and teacher assistant) is used for one group and the other group had also the same as well as learners'…

This mixed-method, longitudinal study investigated the benefits of project-based learning (PBL) on secondary-mathematics students' academic skill development and motivated strategies for learning (i.e., cognitive, social, and motivational). The focus of this study was academic skill development (algebra- and geometry-assessment scores) and other…

A systematic series of studies by De Bock et al. revealed a strong, deep-rooted tendency among secondary school students to apply the proportional model in non-proportional problems involving lengths, areas and volumes of similar geometrical figures. In these studies, however, items were used involving direct measures for area and volume as well…

Relationships among motivation, use of general and content-specific learning strategies, and achievement were examined for 283 high school geometry students early and late in the semester. Results suggest that teachers should emphasize domain-specific strategies when introducing a unit, and emphasize less domain-specific strategies later in the…
