Describes the use of Rasch item statistics for curricular analysis and instructional decision making. Uses a case study of application of the Rasch model in the pilot testing of items selected for criterion-referenced tests developed for grades one through eight in Charleston (South Carolina) schools. (SLD)

This study compared (1) performance on language skills and phonological process measures by 41 kindergarten children with speech/language impairments, and (2) their reading ability in first grade. Children with semantic-syntactic language deficits exhibited more difficulties in reading than did children with articulation impairments. Phonological…

Infants' visual recognition memory (VRM) at seven months was associated with their general intelligence, language proficiency, reading and quantitative skills, and perceptual organization at six years. Infants' VRM, object permanence, and cross-modal transfer of perceptions at one year were related to their IQ and several outcomes at six years.…

Presents activities that utilize representations of the side, front, and top views of three-dimensional configurations of blocks to develop spatial-visualization skills and aspects of the concept of function. Provides worksheets of these open-ended investigations. (MDH)

Describes a mobile computer lab set up in a converted bus that is used by fourth graders as part of the math curriculum. The program, which emphasizes problem solving and spatial visualization, also addresses gender differences and in-service teacher training. The physical arrangements, including provisions for computer security, are described.…

Developed is an examination to determine a student's visualization capabilities. This examination has two versions, both developed to measure visualization ability, time to visualize, and reaction time. This test indicates the learner's ability to visualize complex three-dimensional objects from six principal views. Included are the results from a…

Described is a course that offers students the opportunity to learn the graphics language of computers in conjunction with the traditional engineering design graphics concepts. The course objectives, course description, course administration, and advantages to using the dual approach are included. (KR)

Assesses children's ability to indicate verbally and nonverbally their awareness of two-octave pitch shifts in a familiar song. Compares abilities of English- and Spanish-speaking children by age and by native language. Discovers older children indicate changes more proficiently whereas Spanish-speaking children respond less often. Finds many…

Discusses a variation on tiling that offers opportunities for the construction of the fundamental mathematical concept of constructing abstract units called "unitizing." Tiling integrates geometric and numerical settings to develop spatial sense and present mathematics as constructing patterns. (MDH)

The Academic Programs for Gifted with Excellence and Equity (APOGEE) serves the top 25% of students in various categories, such as disadvantaged, minorities, underachievers, limited English speakers, and students with disabilities. Their teachers have been trained in implementing a student-centered talent development program emphasizing choices,…

Measures of 4traits (cognitive competence, social competence, social maladaption, and personal maladaption) were obtained on 157 persons with mental retardation, using 3 measurements: standardized assessment instrument, day shift staff ratings, and evening shift staff ratings. The multitrait-multimethod matrix procedure demonstrated strong…

Reports on a naturalistic study conducted with 24 low-achieving high school biology students that determined how the teacher and students used two computer-based videodisk programs, a print-based activity, and a dissection laboratory to learn about frog anatomy and to conduct a frog dissection. Future research is suggested. (Contains 14…

A procedure is presented for examining the influence of instruction on responses to test items by extending item response theory to incorporate variables illustrating different amounts of opportunity to learn. Data from the Second International Mathematics Study (grade 8 scores for about 7,000 students) illustrate the discussion. (SLD)

Identified by a study of mathematically precocious youth, 107 academically accelerated gifted students were compared with 107 nonacademically accelerated gifted students. At age 23-25 years, the 2 subject groups exhibited few significant differences, and no evidence of harmful effects of academic acceleration were found. (SLD)

Stimulated recall was used with 28 classroom teachers to examine their thought processes during instruction. Results indicated that at-risk children received more negative comments about attending and ability than did average achievers. Special education students received more positive and negative comments about attending than did average…
