Izsak, Andrew – Cognition and Instruction, 2008
The present study contrasts mathematical knowledge that two sixth-grade teachers apparently used when teaching fraction multiplication with the Connected Mathematics Project materials. The analysis concentrated on those tasks from the materials that use drawings to represent fractions as length or area quantities. Examining the two teachers'…

Kapur, Manu – Cognition and Instruction, 2008
This study demonstrates an existence proof for "productive failure": engaging students in solving complex, ill-structured problems without the provision of support structures can be a productive exercise in failure. In a computer-supported collaborative learning setting, eleventh-grade science students were randomly assigned to one of…

Li, Xiaobao; Ding, Meixia; Capraro, Mary Margaret; Capraro, Robert M. – Cognition and Instruction, 2008
This study reports findings from comparative samples of sixth-grade Chinese and U.S. students' interpretations of the equal sign. Ninety-eight percent of the Chinese sample correctly answered 4 items indicating conceptions of equality and provided conceptually accurate explanations. In contrast, only 28% of the U.S. sample performed at this level.…

Speer, Natasha M. – Cognition and Instruction, 2008
Findings about mathematics teachers' beliefs typically involve broad characterizations of those beliefs that are compared with general descriptions of practices. Teacher development research suggests that changes happen effectively from attention to specific practices. Few investigations of beliefs and practices are done at this level of detail.…

Casey, Beth M.; Andrews, Nicole; Schindler, Holly; Kersh, Joanne E.; Samper, Alexandra; Copley, Juanita – Cognition and Instruction, 2008
This study investigated the use of block-building interventions to develop spatial-reasoning skills in kindergartners. Two intervention conditions and a control condition were included to determine, first, whether the block building activities themselves benefited children's spatial skills, and secondly, whether a story context further improved…

Liu, Yan; Thompson, Patrick – Cognition and Instruction, 2007
Probability is an important idea with a remarkably wide range of applications. However, psychological and instructional studies conducted in the last two decades have consistently documented poor understanding of probability among different populations across different settings. The purpose of this study is to develop a theoretical framework for…

Staples, Megan – Cognition and Instruction, 2007
Recent mathematics education reform efforts call for the instantiation of mathematics classroom environments where students have opportunities to reason and construct their understandings as part of a community of learners. Despite some successes, traditional models of instruction still dominate the educational landscape. This limited success can…

Nolen, Susan Bobbitt – Cognition and Instruction, 2007
In a 3-year longitudinal, mixed-method study, 67 children in two schools were observed during literacy activities in Grades 1-3. Children and their teachers were interviewed each year about the children's motivation to read and write. Taking a grounded theory approach, content analysis of the child interview protocols identified the motivations…

diSessa, Andrea – Cognition and Instruction, 2007
Clinical interviewing is viewed here as a social interactional pattern in order to examine the nature and limits of the technique as a means of scientific data acquisition. I defend the technique against criticisms that it is ecologically suspect and prone to systematic biases, mainly due to influence of the interviewer on the interviewee or to…

Duncan, Ravit Golan – Cognition and Instruction, 2007
Promoting the ability to reason generatively about novel phenomena and problems students may encounter in their everyday lives is a major goal of science education. This goal proves to be a formidable challenge in domains, such as molecular genetics, for which the accumulated scientific understandings are daunting in both amount and complexity. To…

Ellis, Amy B. – Cognition and Instruction, 2007
This paper reports the mathematical generalizations of two groups of algebra students, one which focused primarily on quantitative relationships, and one which focused primarily on number patterns disconnected from quantities. Results indicate that instruction encouraging a focus on number patterns supported generalizations about patterns,…

Smith, Carol L. – Cognition and Instruction, 2007
This study explores whether the development of students' understanding of matter as something that occupies space and has weight involves conceptual change and restructuring rather than only simple belief revision. Based on an analysis of how the concepts in students' initial matter theory (henceforth MT1) may differ from the concepts in the…

Morris, Anne K. – Cognition and Instruction, 2007
This study was designed to identify the types of understandings, skills, and beliefs that affect pre-service teachers' evaluations of students' mathematical arguments in classroom contexts. Thirty-four pre-service teachers read a transcript of a third grade lesson in which the students were expected to prove a generalization. To investigate…

Paris, Alison H.; Paris, Scott G. – Cognition and Instruction, 2007
This study provided 5 weeks of direct strategy instruction about narrative elements and relations in 4 first-grade classrooms (n = 83), all with materials that made minimal decoding demands on children's reading. Two comparison classrooms (n = 40) received comparable instruction on language development and poetry. A battery of assessments given at…

Emergent leadership was examined in 12 discussion groups in 4 fourth-grade classrooms. Children's leadership moves were coded from transcripts of 10 free-flowing, open-format discussions of each of the 12 groups. The transcripts encompassed 26,000 turns for speaking, including 22,000 child turns of which 1,700 were judged to serve one of five…
