This study addresses the investment hypothesis of fluid on crystallised abilities onto academic achievement (Gf [right arrow] Gc [right arrow] "Achievement"), which might hold to a greater extent at earlier than at latter educational stages. We compared this prediction with two independent groups of secondary (n = 192, 113 females) and…

We explored the mediating role of prior knowledge on the relation between intelligence and learning proportional reasoning. What students gain from formal instruction may depend on their intelligence, as well as on prior encounters with proportional concepts. We investigated whether a basic curriculum unit on the concept of density promoted…

Complex Problem Solving (CPS) can be defined as those psychological processes that enable a person to achieve goals under complex conditions, which are characterized by their complexity, connectivity, dynamics, lack of transparency, and polytely. Although many hypothesized influences have previously been tested concerning their relevance for the…

This study investigated the role of broad cognitive processes in the development of mathematics skills among children and adolescents. Four hundred and forty-seven students (age mean [M] = 10.23 years, 73% boys and 27% girls) from an elementary school district in the US southwest participated. Structural equation modelling tests indicated that…

Although much educational research has investigated the relative effectiveness of different educational interventions and policies, little is known about the absolute net benefits of K-12 schooling independent of growth due to chronological age and out-of-school experience. The nearly universal policy of age tracking in schools makes this a…

Students (n = 328) from US and UK universities completed four self-report measures related to intellectual competence: typical intellectual engagement (TIE), openness to experience, self-assessed intelligence (SAI), and learning approaches. Confirmatory data reduction was used to examine the structure of TIE and supported five major factors:…

Depression has been linked to cognitive deficits and learned helplessness models in various theories. To examine depression effects on abstract problem solving ability and the relationship between intelligence and anxiety, 66 of 303 college students (23 male, 43 female), evidencing least and most depressed states as assessed by the Beck Depression…

Using Raven Progressive Matrices Test items, this study developed an empirical measure of subjects' ability to create new problems. The relationship between this ability and problem solving skills was examined. A very low correlation was found between inventing and solving problems. Problem creation was more difficult than problem solving. (BS)

Many science curriculum development projects have the goal of increasing students' ability to employ scientific or formal reasoning strategies. Argues that longitudinal data of students who acquired formal reasoning strategies as a consequence of specific instruction are needed to provide evidence that these skills will help in other academic…

Fluid intelligence (Gf) is a general relation-perceiving capacity determined by each person's cortical, neurological connection count development. Its processes are involved in reasoning, concept formation and problem-solving, where acculturation has little effect. Crystallized intelligence (Gc) manifests knowledge and general comprehension,…

An information-processing framework is presented for understanding intelligence. Two levels of processing are discussed: the steps involved in solving a complex intellectual task, and higher-order processes used to decide how to solve the problem. (MH)

Developmental patterns in the solution of verbal analogies, especially the recognition of higher-order analogical relations, were traced. The investigation sought to: (1) provide new developmental tests of a componential theory of analogical reasoning; (2) identify strategy changes during the transition from midchildhood (grade 3) to adulthood…

In this interview, author Art Costa asserts that the teaching of either content or thinking skills in isolation is unproductive. To combine these approaches, he recommends selecting content for its relationship to thought processes. He also observes that administrators who model intelligent behavior thereby create a climate for thinking. (TE)

The "componential" theory of intelligence explains intelligence in terms of three types of component processes that make up intelligent performance. The first of these, "metacomponents," are the higher-order or executive processes that one uses to plan what one is going to do, monitor what one is doing, and evaluate what one…

Evidence for suggested basic differences in the abstract reasoning capacity of Negro and Caucasian children includes consistent findings of significantly poorer performance by Negroes on Raven's Progressive Matrices (PM). This study investigated the PM performance of Negro children taught algebra via a discovery method of instruction. It was…
