The "Building a System of Tens Casebook" was developed as the key resource for participants' Developing Mathematical Ideas seminar experience. The thirty cases, written by teachers describing real situations and actual student thinking in their classrooms, provide the basis of each session's investigation of specific mathematical…

Self-assessment is a process during which students evaluate the quality of their work in a given domain based on explicitly stated criteria. Accurate self-assessments improve students' academic achievement. Yet, students often have difficulties assessing their own work. It is possible that appropriate instructional supports will help students…

This article describes the use of a case report, Multiplication as original sin (Corwin, R. B. (1989). "Multiplication as original sin." "Journal of Mathematical Behavior, 8", 223-225), as an assignment in a mathematics course for preservice elementary teachers. In this case study, Corwin described her experience as a 6th grader when she revealed…

Students get excited about science when they investigate real scientific problems in the classroom, especially when the investigation extends over several weeks. This article describes a health-science problem-based learning (PBL) investigation that a group of teachers and teacher educators devised together for a group of fourth- to sixth-grade…

This article discusses an action research study on how an integrated project-based curriculum could enhance students' learning of mathematics and social studies content. "A Tale of Two Cities" a thematic unit, which was developed and used with three classes of sixth-grade mathematics students (95 total) as part of the study. Results shows that "A…
