Research suggests that experts and beginners use qualitatively different writing processes when given the same text to write. Throughout their writing, experts tend to create a network of executive, structural, and content problems that they continually refine and coordinate as they bring the text to fruition. Novices, in contrast, tend to focus…

Insects are fascinating creatures--especially when you and your students get up close and personal with them! To that end, the authors facilitated an inquiry-based investigation with an emphasis on identification of the different types of insects found in the school yard, their characteristics, their habitat, and what they eat, while engaging the…

Moral development research has often focused on the development of moral reasoning without considering children's understanding of moral advisors. We investigated how children construe sources of moral advice by examining the characteristics that children deem necessary for reasoning about moral or scientific problems. In two experiments, children…

Analyzes a didactical sequence for the teaching of addition and subtraction procedures and algorithms. Uses didactical procedures by children in problem solving activities in order to gain a better understanding of the interaction between numbers, numeration, and operations knowledge which are involved in the construction of addition and…

The relationship between the development of reversible thought and performance in arithmetic equations among children was investigated. Subjects were 86 second grade boys and girls. Two reversibility tasks and 20 addition and subtraction equations were administered. Results indicated significant correlations between the two variables only among…

Children in the response-cost condition required more trials to reach a performance criterion and exhibited longer response times than children receiving reinforcement only. Response cost appeared to produce a negative effect that interfered with problem solving ability. (Author/RL)

The purposes of the present investigation was to factor analyze the results of the administration of the Purdue Elementary Problem Solving Inventory to 361 second-graders. The Inventory was designed to assess twelve distinct skills involved in human problem solving. Tetrachoric intercorrelations were generated from the item scores and a principal…

A computer-generated game called Fish Chase was developed to present drill-and-practice exercises on addition facts. The subjects of the study were 19 second-grade pupils. The results indicate a computer game can be used effectively to increase proficiency with basic facts. (MP)

Kindergartners and second graders listened to stories about problem solving that had similar or dissimilar protagonists, themes, and goal objects to those in target problems they were asked to solve. Kindergartners, but not second graders, were likely to transfer a solution associated with the same goal object from the story problem to the target…

Presents examples of problem tasks that promote communication and develop or reinforce important mathematical concepts. Problems that have multiple solutions or methods of solution are best in stimulating discussion, creativity, and risk taking. Examples were chosen from TOPS: Communication Deck Grades 1 and 2 (Greenes, Schulman, and Spungin;…

This research investigates how individual differences in strategic abilities affect problem solving and, more particularly, the extent to which hypothesis-generating skills predict effective hypothesis testing. Additional questions concerned the effects of content and timing of instructional advice on children's problem-solving strategies, and…

This study investigated children's representation of addition and subtraction problems with canonical and noncanonical number sentences, to see whether children would directly represent the structure of a problem if both types of sentences were available. Subjects were 22 first graders and 41 second graders randomly assigned either to a Canonical…
