Intellectual engagement (IE) refers to enjoyment of intellectual activities and is proposed as causal for knowledge acquisition. The role of IE for cognitive development was examined utilizing 2-year longitudinal data from 112 ninth graders (average baseline age: 14.7 years). Higher baseline IE predicted higher baseline crystallized ability but…

This study explored the effects of high-stakes testing and accountability on the fundamental practices associated with middle school philosophy. Participants were middle school educators, including administrators and teachers, from Pennsylvania middle schools. An online survey was used to collect data for this study. The survey addressed the…

Background: "Volume & Heaviness" was one of three Piagetian tests used in the CSMS survey in 1975/76. However unlike psychometric tests showing the Flynn effect--that is with students showing steady improvements year by year requiring tests to be restandardized--it appeared that the performance of Y7 students has recently been…

Ten metalinguistic tasks of intellectual development were studied in five- and six-year-old children using factor analysis. Results suggested that metalinguistic awareness can be viewed as developing in association with other intellectual activities, and that it can be conceived as a unitary construct.

Two years after the end of a two-year intervention program set within the context of science learning intended to promote formal operational thinking, achievement of students (n=234) was tested by their results on British National examinations taken at age 16. Male experimental subjects achieved an average of 40 percent more grades of C or above…

The cognitive determinants of number analogy performance were studied by systematically manipulating the processing demands imposed by the items. To explore sources of developmental differences in analogical reasoning, subjects were included from two age levels, grades 4 and 5 and college. To allow the investigation of individual differences in…

This study of 28 girls (ages 2-19) with Rett Syndrome found profound handicaps in the intellectual and adaptive areas, according to standardized tests. Subjects seemed capable of learning some self-help skills at a basic level. The Cattell Mental Age was significantly negatively correlated with chronological age. (JDD)

In this predictive study, the variables of College Basic Academic Subjects Examination (C-BASE) Science score, American College Test (ACT) Science score, Group Assessment of Logical Thinking (GALT) score, and total number of college science courses completed were investigated as predictors of science process skills and physical science…

Multiage settings are alternative educational groupings that promote complexity in young children's thinking. Grouping children across ages and grades encourages interconnectedness in social and intellectual development. This study compared the academic achievement of one group of multiage students to national norms on standardized achievement…
