It has been established that, in Bayesian tasks, performance and typical errors in reading information from filled visualizations depend both on the type of the provided visualization and information format. However, apart from reading visualizations, students should also be able to create visualizations on their own and successfully use them as…

In this study, we used problem posing as a measure of the effect of middle-school curriculum on students' learning in high school. Students who had used a standards-based curriculum in middle school performed equally well or better in high school than students who had used more traditional curricula. The findings from this study not only show…

This paper examines the perceptions and understandings of ten grades 1 and 2 Singapore mathematics teachers as they learned to use clinical interviews (Ginsburg, "Human Development" 52:109-128, 2009) to understand students' mathematical thinking. This study challenged teachers' pedagogical assumptions about what it means to teach for…

Proposes a model of doctoral student persistence and attrition in which student participation in the life of the department and discipline lead to increased student integration which is crucial for student success. Discusses students' obstacles to participation and implications for the retention of mathematics doctoral students. (Author/KHR)

This study describes and contrasts theoretically and empirically problem solving of situated problems in school and the real world at the macro level as a social-cultural activity system and analyzes the process of solving situated problems by high school students at the micro level as an activity. Three potentially experiential problem tasks were…

Described are differences in the mathematical problem-solving performance of third-grade gifted and fifth-grade average students observed during an eight-week period. Results indicate that attitudes, motivation, and belief systems were important to performance. There were major differences in problem-solving behavior between boys and girls.…
