A longitudinal study was conducted to identify unique sources of individual differences in later understanding of the equal sign as a relational symbol of equivalence (i.e., formal understanding of mathematical equivalence). The sample included 141 children from a mid-sized city in the Midwestern United States (M[subscript age] = 6 years, 2 months…

The education of children with disabilities in the regular educational environment has long been an expectation of legislation in many countries. Yet some children with autism spectrum disorder (ASD) are educated outside regular classes. Despite the obvious importance that educational placement holds for any child, there is limited research on how…

The authors designed and conducted this study using the predictive analytics to determine the different science performance predictors of the first batch of K to 12 curriculum in Valencia District, Valencia, Negros Oriental. The authors had chosen three kinds of predictors namely; student-related predictors, teacher-related predictors, and…

Background: The extant literature demonstrates that children with autism spectrum disorder (ASD) often have difficulty interacting and socially connecting with typically developing classmates. However, some children with ASD have social outcomes that are consistent with their typically developing counterparts. Little is known about this subgroup…

The study was performed in St. Petersburg in 2015 and comprised 34 children with diagnosed Down's syndrome (DS) aged 9-15 (mean 11) years (17 boys, 17 girls) who attended special schools. Control group was made up of 34 clinically healthy normal intelligence schoolchildren matched for age, sex and geographical distribution. The mothers were…

This article deals with the concept of misaligned parents' aspirations, its relationship with student background characteristics, and its effects on long-term student performance. It is defined as the difference between parents' educational ambitions for their child and the child's actual capacities. Multilevel regression analyses on a sample of…

This study examined the student-level and instruction-level predictors of narrative writing fluency and quality. Participants included 120 third-grade students from 13 classrooms. Student predictors included measures of reading, handwriting, spelling, IQ, grammatical understanding, and gender. Instructional predictors focused on the amount of time…

Among the variables considered, the best predictor of achievement in biology is the IQ of the students; the type of ninth-grade science course completed seems to have very little to do with subsequent performance in biology. (DS)

A meta-analysis of 267 studies conducted between 1950-1980 found that auditory and visual perceptual skills can successfully increase the accuracy of predicting reading achievement, but the magnitude of increases in predictive accuracy was contingent upon the combination of variables studied and was significantly reduced if an IQ score was known.…

A meta-analysis of 30 studies found the following learner characteristics influenced the treatment responsiveness of early literacy interventions: rapid naming; problem behavior; phonological awareness; alphabetic principle; memory; IQ; and demographics. With the exception of the demographic category, the obtained effect sizes for the primary…

Composite reading performance data from 223 pairs of identical twins and 169 same-gender fraternal twins in which at least one member was classified with reading disability were subjected to multiple regression analysis. Results indicated that the genetic etiology of reading disability differs as a linear function of IQ. (Contains extensive…

Analysis of achievement test scores of 439 tenth-grade students found the hypothesized variables of IQ, socioeconomic status (SES), self-rated motivation, peer-rated studiousness, peer-group status, and parent-rated home environment contributed uniquely to achievement variance; SES, sex, and language medium of instruction were superfluous in the…

A model for the development of scientific reasoning in adolescents was formulated largely upon the basis of Piagetian theory. Included as potential determinants of scientific reasoning were: experience; age; locus of control; field dependence-independence (FID); rigidity/flexibility; intelligence quotient (IQ); and sex. Causal relationships…

The aim of the research described in this article was the development of an instrument to measure social emotional characteristics and special educational and pedagogical needs of students in the last grade of primary education. Questionnaires were developed for teachers as well as for students. Exploratory factor analyses showed that the factors…
