Very close age spacing was an obstacle to high academic performance for later borns. In family relations and self-esteem, first borns scored better and performed in school as well as their potentially much more able younger siblings, regardless of age spacing. (Author)

Forty children (ages 7-11) referred for evaluation of learning problems, who had normal scores on measures of academic achievement, were compared to 81 similarly referred children who had scored low. Children with normal achievement scores had higher IQs and better decoding skills, however, the two groups showed similar neuropsychological…

Relationships between six home environment measures, achievement and intelligence tests were examined by stepwise multiple regression analyses for a sample of 60 eight-year old children. Home variables were most successful in predicting achievement test scores, less successful regarding culture-dependent intelligence test scores, and least…

Three measures of field dependence were used to determine whether: (1) Mexican American students are more field dependent than Anglo Americans; (2) intercorrelations between the tests are significant and comparable for both cultures; and (3) field dependence significantly affects academic performance. These assumptions were generally not…

Trotman's study (EJ 168 902) correlating child rearing in Black and White samples to children's achievement and intelligence is criticized. Trotman made several erroneous conclusions, and did not add important information about the nature nurture controversy as it applies to racial differences in intelligence. (Author/BH)

In an attempt to investigate factors surrounding educational performance among different ethnic and racial groups, several areas are examined: (1) segregation; (2) performance levels and intelligence quotient variables among various ethnic groups; (3) intergroup differences among segregated and nonsegregated groups; (4) socioeconomic variables;…

This study was conducted to determine how the pattern of learning on an abstract concept, plate tectonics, differed between groups of different cognitive levels, sex, and intelligence quotient (IQ). The intensive time-series design was used to examine the achievement of eighth grade and ninth grade earth science students. The unique characteristic…

Much research shows that the correlation between IQ and school performance is consistently high. However, some evidence indicates that this relationship is not consistent but is moderated by classroom psycho-social environment at the first-grade level. Data from IQ tests, the Devereux Elementary School Behavior Rating Scale, number of attendance…

This study investigates the effect of curiosity in first and second grade children as an individual difference variable in learning in a computer-based interactive learner control environment and discusses the implications for instructional designers and educators. The instruction was an art education lesson containing both facts and concepts. The…
