An information-processing model was tested for a laboratory visualization task that represents one adaptation of a standardized spatial ability test. The pattern of results suggests that individual differences are a function of differences in the accuracy and/or quality of the mental representation, not just speed of processing. (Author/BW)

Today, mathematics education faces two major challenges: raising the floor by expanding achievement for all, and lifting the ceiling of achievement to better prepare future leaders in mathematics, as well as in science, engineering, and technology. Many students lack access to higher-level mathematics courses and teaching at all levels of…

The present findings imply that a readability formula is not an effective writing production criterion, even when the writer does not deliberately write to the formula. Comprehensibility of text might be better controlled through the proper use of the transformer concept (MacDonald-Ross and Waller). (Author/PN)

The success of distance teaching depends largely on students' comprehension and appreciation of print communication. A communication gap exists, and many students are unable to recognize levels of complexity presented to them. Changes in course structure can help alleviate this learning problem. (MSE)

Faced with a problem in which the probability of obtaining the correct answer was 70 percent, 2 of 23 kindergartners and 18 of 19 second graders generated an appropriate strategy. When the probability of a chance correct response was reduced to .45, 23 of 35 kindergartners generated an appropriate strategy. (Author/GDC)

The influence of feedback on the cognitive task performance of 30 adults with mental retardation having either high or low self-esteem was assessed. All subjects performed two memory tasks (easy, difficult) under one of three feedback conditions (social, computer, and no feedback). Social feedback was most effective in altering the positive…

Results of five experiments showed that in certain situations recall varied with processing difficulty for both children and college students. This was primarily due to enhanced cue discriminability. The relation between processing difficulty and developmental increases in recall seemed to be mediated by constructability problems and resource- and…

Examined potential central processing strategy differences among subgroups of children on a series of elaborative encoding tasks. Children in lower verbal and learning ability subgroups differed from those in higher ability groups in how they shared, discriminated, and selectively allocated resources between recall tasks. (RH)

Highly skilled and less skilled college readers (n=29) were compared on several information-processing and language-comprehension tasks that tap cognitive components of reading. Results confirm that both areas distinguish skilled and less skilled readers and suggest that reading ability is a continuous function. (SLD)

Performance of congenitally blind children and blindfolded children was compared on tasks requiring spatial reasoning and shape recognition. Blind subjects performed at least as well as blindfolded subjects on simple two-dimensional tactual processing tasks, but less well on more complex tasks requiring them to store, compare, and label objects.…

Investigates two problems: (1) do learning effects accrue in accuracy or response time when computerized tests are administered in two sessions? and (2) what are the effects of tonal pattern order and contour types on average item difficulty and length of response time for children with different levels of achievement? (DSK)

Two experiments examined developmental changes in reasoning about intensive quantities--predicting mixture intensity of pairs of liquids with different intensities of red color. Results showed that cognitive averaging in this domain developed late and slowly. Predominating up to 12 years was an extensivity bias, a strong tendency to use rules that…

This article examines the significance of emotion for the processes of teaching, studying and learning. The goal is to demonstrate on the basis of both theoretical examination and empirical data that emotional processes are crucial for human learning and should be taken into account in online teaching and learning as well. Emotional factors during…

This study examined the hypothesis that age-related increases in reasoning ability are associated with the ability to represent relations of increasing complexity, defined as the number of entities related. The study's purpose was to determine the extent to which this ability to process relations with three entities increased between ages 4 and 8…

An approach is described that reveals the hierarchical test structure (HTS) based on the cognitive demands of the test items, and conducts a linear trait modeling by using the HST elements as item difficulty components. This approach, referred to as the Hierarchical Latent Trait Approach (HLTA), employs an algorithm that allows all test items to…
