This issue contains articles on mathematical modeling of school arithmetic word problems; cognitive load theory; cognitive effects of practical experience for high and low achievers; perspectives of college-bound students on learning mathematics; and training-based assessment of school achievement.

The ability of 248 older adults to improve their performance on fluid intelligence tests, with or without tutor-guided instruction in cognitive skills, was studied using multidimensional longitudinal structural equation models. Results suggest considerable plasticity in adult intellectual function and the capacity to improve performance. (SLD)

Presents a model of the tutoring process that takes into account the evolving tutor/student relationship and the subject matter concerns that the tutor is helping the student master. Reports illustrative data from case studies from which the model is derived. (15 references) (MDH)

Responds individually to Shoenfeld's objections that Ohlsson, Ernst, and Rees' model is unclear; that the hypotheses about learning are unjustified; that the models have not been tested against extant data; and that it is unclear whom the model models. (MDH)

The developmental model of self-concept proposed by M. Lynch and M. Levy (1982) is extended through the entire adult life cycle. Self-concept is seen as a set of cognitive rules that have affective or cognitive consequences and that operate like the ego functions proposed by Freud. (SLD)

Attempts to integrate recent models of social systems based on age and cognitive personality research with research on adolescence. Presents a conceptual model of how adolescents set personal goals, construct cognitive strategies, and evaluate their success in an age-graded sociocultural context. Discusses future directions for research based on…

Describes the current state of knowledge about human decision-making and problem-solving processes, explaining recent developments and their implications for management and management training. Rational goal-setting is the key to effective decision making and accomplishment. Bounded rationality is a realistic orientation, because the world is too…

The item-response-theory-based (IRT) rule-space model was used to diagnose student knowledge about how exponents behave in multiplication and division in a sample of 431 tenth-grade students. Implications for using feedback from the rule-space model in instruction and assessment are discussed. (SLD)

Explores ways for librarians to improve search strategies in a globally networked computing environment. Discusses browsing versus more structured search strategies; thinking processes and information-seeking processes; supplementing the traditional reference interview with computer-based reference assistants; models for automating the reference…

Reviews studies examining the effects of theoretically-based Logo environments on young children's metacognitive processing and the extent to which sociocognitive processes mediate those effects. Findings suggest that Logo fosters development of metacognitive processing, in part by engendering high-level conflict resolution. Implications are…

Evaluated the PREG conceptual model of human question asking. Found the model was sufficient as it accounted for nearly all of the questions produced by students, and was discriminating in that it could identify the conditions in which particular classes of questions are or are not generated. (Author/SD)

The purpose of this study was to test a theoretical model that examined the extent to which cognitive readiness to parent, perceived difficult child temperament, observed parenting behaviors, and positive coping styles predicted parenting stress among young, low-income, first-time, African-American mothers. One hundred and twenty African-American,…

For three biology professors, visualizing molecular processes is central to thinking in their discipline. This chapter reports their attempts at getting students to make this same cognitive move and the results of their assessments. (Contains 2 figures.)

This study was an investigation of reading and spelling errors of dyslexic Arabic readers ("n"=20) compared with two groups of normal readers: a young readers group, matched with the dyslexics by reading level ("n"=20) and an age-matched group ("n"=20). They were tested on reading and spelling of texts, isolated…

This article presents a longitudinal-sequential analysis of the developmental and reciprocal relationships between self-reported delinquency and moral reasoning (as measured with the Dutch version of the short form of the Defining Issues Test). Between 1991 and 1997 a large sample of 846 Dutch adolescents and young adults (15-23 years in 1991) was…
