Textbooks, like many other resources teachers have at hand, are meant to be an aid for instruction; however there is little research with textbooks or on their potential to develop metacognitive knowledge. Metacognitive knowledge has received substantial attention in the literature, in particular for its relationship with problem-solving in…

Simple and complex addition problems were presented for true/false verification to 30 undergraduate students to test a general model for cognitive addition. Problems were presented on a microcomputer, with reaction time (RT) and response accuracy recorded. Models for addition were fit to average RT data using multiple regression techniques. These…

Investigates children's knowledge of concrete versions of additive composition, commutativity, and associativity. Reports that in study one, four-to five-year-olds (n=24) and five- to six-year-olds (n=25) judged the equivalence of conceptually related addition problems using groups of objects. States that in study two, five- to six-year-olds…

Investigated the effects of individual difference variables of field dependence/independence and spatial visualization ability on the performance of college students in three modes. The extent to which four variables account for variability in retention test performance on certain tasks was also viewed. (MP)

Investigates the effects of children solving addition and subtraction problems collaboratively in contrast to solving problems on their own. Explores the effects of ability and gender on the outcomes of group collaboration. Presents and discusses the results. Includes references and an appendix. (CMK)

This investigation capitalizes upon the information processing models that depend upon measurement of latency of response to a mathematical problem and the decomposition of reaction time (RT). Simple two term addition problems were presented with possible solutions for true-false verification, and accuracy and RT to response were recorded. Total…

This unit is 1 of 12 developed for the university classroom portion of the Mathematics-Methods Program (MMP), created by the Indiana University Mathematics Education Development Center (MEDC) as an innovative program for the mathematics training of prospective elementary school teachers (PSTs). Each unit is written in an activity format that…
