Purpose: This study aims to clarify the process of students' discussion in a problem-solving lesson developed autonomously by a teacher. It is expected to contribute to the accumulating and theorizing of teachers' professional development in school-based curriculum studies. Design/methodology/approach: A transcript-based lesson analysis (TBLA) was…

While collaborative Intelligent Tutoring Systems (ITSs) have been designed for older students and have been shown to support sense-making behaviors, there has not been as much work on creating systems to support collaboration between elementary school students. We have developed and tested, with 84 students, individual and collaborative versions…

In order to address concerns with the underrepresentation of spatial thinking in K-12 curricula, (National Research Council, 2006), Valentine and Kopcha (in press) designed and implemented a learning environment integrating cases as alternative perspective (Jonassen, 2011) in the context of eighth-grade mathematics. The design aimed to provide…

Researchers have long recognized the potential benefits of open-ended computer- based learning environments (OELEs) to help students develop self-regulated learning (SRL) behaviours. However, measuring self-regulation in these environments is a difficult task. In this paper, we present our work in developing and evaluating "coherence…

Problem solving plays an important role in mathematics and should have a prominent role in the mathematics education. The term "problem solving" refers to mathematics tasks that have the potential to provide intellectual challenges for enhancing students' mathematical understanding and development. In addition, the contextual problem…

Few early intervention efforts have improved the representation of women in computer science and engineering (CSE) disciplines, but pair programming has shown promise for reducing gender differences among college students. The current study is the first to examine this promising practice in middle school. In an effort to better understand what…
