High and low level questions as determined by a panel of evaluators were combined with corrective feedback and attribute isolation feedback to form four versions of a computer-based science lesson. The sample consisted of 154 high school chemistry students in a suburban high school. The primary hypothesis was that students who received high level…

Cognitive research of the 1970s has shown that both content factors (topical world knowledge and knowledge about textual organization) and process factors (attention, encoding, inference, retrieval, and executive monitoring) influence comprehension. Classroom research during the same decade has shown that the greater the proportion of time…

This paper offers a variety of approaches to teaching the concept of time. Many social studies courses traditionally emphasize time as measured by clocks and as useful for recording when events occur in relation to each other. In addition to this approach, the author suggests that students should reflect upon four other modes of time. These are…

This study focused on two questions concerning children's attention to verbal stimulus: How do children of different reading ability attend to repeatedly presented words? Are there differences in children's patterns of attention to words as compared to less meaningful materials? Toward the end of an academic year, 40 first-graders and 40…

Seven researchers met with three representatives from the National Institute of Education (N.I.E.) in January 1978 to draft a research and demonstration agenda for N.I.E. on the relationship between leisure time uses of television and school performance. Of particular concern to N.I.E. is the role of federal policy and programs in addressing the…

Two experiments comprised this study comparing the ability of children from ages 4 to 12 years to discriminate the order in which items from a previously presented sequence of stimuli had been presented. The hypotheses were that the discrimination of recency (DR) improves with age, that broader separations of test items are easier to discriminate…

In order to investigate developmental changes in multiple classification, a matrix task was administered to 80 kindergarten first, second, and third grade children. Correct solution of the incomplete matrices, comprised of three pictures in a row and three pictures in a column meeting at a blank intersection, required identification and…

This working paper is intended for inclusion in a curriculum manual for future publication, possibly in 1972. A guide for preschool teachers, it offers goals and methods designed to increase thinking power in children and given them the opportunity to express themselves in their own way. The basic elements of the Cognitive Preschool Curriculum are…

Examines the implications of temporal separation for children's developmental differences in inferences drawn about an individual's characteristics after observing multiple instances of that individual's behavior. Also tests two competing hypotheses about how young children process information separated in time. (HOD)

A correlation exists between verbal ability test scores and name identity minus physical identity reaction times in a letter matching task. The present results support Carroll's (1981) suggestion that the reaction time difference is related more to speed than power component of standardized tests and is not optimum for prediction. (Author/RD)

Two groups of undergraduates differing in reading ability were tested on a number of reaction-time tasks designed to determine the speed of encoding visual information at several different levels, tests of sensory functions, verbal and quantitative reasoning ability, short-term auditory memory span, and ability to comprehend spoken text.…

Stories were constructed in which minor variations in content influenced the relationship existing between statements. The stories had four episodes, which were either logically related or independent. First and third graders could more accurately recall the structure of the logically organized episodes than that of the temporally listed episodes.…

Results of an investigation of the permanency of gains in problem solving, listening, and abstract thinking among fifth graders are reported. Findings indicate that the experimental group with listening training shows greatest gains. (MH)

Three experiments focused on the function relating children's response time to adults' response time in corresponding conditions. In all experiments, children's response times increased in a linear manner as a function of adults' response times. (BB)

Two studies with 658 white and 353 African-American elementary school children performing reaction time tasks are offered in support of Spearman's hypothesis about the relative size of the mean African-American-white differences on mental tests as a function of the tests' loadings on psychometric "g."
