This study investigated students' turn-taking patterns during dialogic collaborative problem solving, with analysis based on the participation-shift analytical framework. 168 primary fourth-grade students were assigned to 42 groups and worked on three mathematical problems for a total of 30 minutes. Group-level analysis revealed that most students…

Get an inside look at the discourse interactions of third- and fourth-grade students as they consider various design proposals to solve an engineering problem and negotiate a group decision. The authors present possible factors that impact student teamwork and provide recommendations for teachers to develop students' skills for group engineering…

This study presents three students who are bilingual with learning dis/abilities in small group mathematics discussions. The three students showcased their abilities as problem solvers, justifiers, and evaluators of basic operation and fractional understanding. This paper presents the teaching practices used to support the mathematical agency of…

In this article, the authors illustrates techniques for integrating diverse learners in shared mathematical contexts while providing differentiated support or challenge, as necessary. The techniques described were developed for a curriculum project entitled Learning Mathematics through Representations (LMR). A premise of LMR is that students'…

It is important to use rich problem-solving tasks to develop students' understanding of important mathematical ideas (NCTM 2000). Rich tasks are complex, nonalgorithmic, and nonroutine, requiring reasoning, problem solving, and communication of thinking. Evidence has shown that using rich tasks in student-centered classrooms is especially…

For the forty-third time, the Association for Educational Communications and Technology (AECT) is sponsoring the publication of these Proceedings. Papers published in this volume were presented online during the annual AECT Convention. Volume 1 contains 37 papers dealing primarily with research and development topics. Papers dealing with the…

What happens when children come across texts that push the boundaries of what they expect to encounter when they pick up a picture book? There exists a genre of nontraditional picture books, commonly referred to as "postmodern picture books," which is characterized by a variety of alternative literary and illustrative devices. Given that…
