Investigated how an expert elementary teacher implemented constructivist-oriented teaching strategies to engage students' critical thinking skills when learning creative dance. Data from teacher and student interviews and videotapes of creative dance lessons provided contextual information about using appropriate constructivist-oriented teaching…

This article extends and strengthens the knowledge in pieces perspective (diSessa, 1988, 1993) by applying core components to analyze how 5th-grade students with computational knowledge of whole-number multiplication and connections between multiplication and discrete arrays constructed understandings of area and ways of using representations to…

This paper reports the results of an exploratory study of the perceptions of and approaches to mathematical proof of undergraduates enrolled in lecture-based and problem-based "transition to proof" courses. While the students in the lecture-based course demonstrated conceptions of proof that reflect those reported in the research literature as…

The author recently read a research paper by Padberg (2002), in which the development of understanding associated with decimal fractions was studied. Padberg (2002) outlined the situation that existed in Germany, where students were introduced to decimal fractions in the sixth year of school. He claimed that it was assumed students would have a…

This paper presents a three-phase model of how formative evaluation research can inform the design of educational computer software products. Used as an illustrative case is a program of formative research conducted on "The Talking Clock," a computer assisted instructional software product designed to help children in kindergarten through second…

This study examined the science process skill of prediction problem solving using naturalistic research methodology and information-processing theory. The think-aloud interview led to the identification of several specific program exploration and prediction behaviors. A total of 14 high school biology students made predictions concerning the…

Thirty six senior students in chemical engineering were randomly assigned to three treatment groups in an experimental study that examined the impact of different instructional strategies for troubleshooting malfunctions in a computer-based simulation of a chemical processing plant. In two groups, different types of worked examples,…

This report describes a program for improving the transfer of the learning of different techniques used in computer applications. The targeted population consisted of sophomores and juniors in a suburban high school in a middle class community. The problem was documented through teacher surveys, student surveys, anecdotal records and behavioral…

Reports a study that examined the effects of conceptual orienting questions and differences in prior knowledge on factual learning and problem solving in biology. Tenth graders who participated in control or orienting questions groups completed posttests. Results indicated that question groups outscored the control group. (SM)

This study compares the effects of forum discussion with metacognitive guidance versus forum discussion without metacognitive guidance (Forum) on solving real life mathematical tasks and self-regulated learning. Participants were 43 Grade 7 students (boys and girls) who practiced online problem-solving in two classes. The metacognitive guidance…

Recent papers document that student problem-solving competence varies (often strongly) with representational format, and that there are significant differences between the effects that traditional and reform-based instructional environments have on these competences [Kohl and Finkelstein, Phys. Rev. ST Phys. Educ. Res. 1, 010104 (2005); Kohl and…

With few exceptions, the development of adult intelligence assessment instruments has proceeded along the lines of the Binet-Simon tests for children, stressing psychological assessment over the evaluation of what an individual knows. These tests, developed over 90 years ago, were quite effective in predicting school success, but were much less…

Children who come to school without numerical game-playing experience have trouble with math relationships in direct-instruction situations. This article explores the varied roles of active thinking, social interaction, previous knowledge, and child-initiated choice in children's development of math concepts. Self-esteem cannot be built by doing…

The effects of students' misconceptions, declarative knowledge, and stimulus conditions on students' solutions to a problem in basic electricity were studied for 80 undergraduates at Iowa State University (Ames). The implications of the findings of influence by knowledge and stimulus conditions are discussed. (SLD)

We present a methodology for designing better learning environments. In Phase 1, 6th-grade students' (n = 223) prior knowledge was assessed using a difficulty factors assessment (DFA). The assessment revealed that scaffolds designed to elicit contextual, conceptual, or procedural knowledge each improved students' ability to add and subtract…
