Research suggests that individual differences in math abilities correlate with approximate representations of quantity that are supported by a primitive Approximate Number System (ANS). However, relatively little research has addressed the direction of this association in early childhood. Here we examined the development of the ANS and math…

Studies with U.S. secondary second language (L2) learners have revealed individual differences (IDs) in first language (L1) skills and L2 aptitude and shown that these IDs are related to L2 achievement and proficiency. In this study, U.S. students were administered measures of L1 achievement, L1 cognitive processing, and L2 aptitude; followed…

Across multiple schools and sites, the impact of grade-at-intervention was evaluated for children at risk or meeting criteria for reading disabilities. A multiple-component reading intervention with demonstrated efficacy was offered to small groups of children in 1st, 2nd, or 3rd grade. In a quasi-experimental design, 172 children received the…

This study investigated the complex influences of individual differences and school contexts on the growth of mathematical reasoning skills in high school, with particular emphasis on differences in academic preparation, demographics (i.e., race/ethnicity, gender and socioeconomic status), and school characteristics. Students' growth of…

Distinctions were made between three classes of statistical linkage: equivalence, concordance, and prediction. These distinctions were based on rational content considerations and empirical statistical relationships. A large database involving SAT I and ACT scores was used to determine which type of linkage was best suited for different scores and…

This paper describes how results on the ACT and SAT I can be compared through statistical linking procedures.

Achievement gaps in standardized tests consist of the differences between test scores of students of color and those of white students and between scores of poor children and those of their wealthier peers. Maylone determines student testing behaviors, herein referred to as TestThink, which reflect differences in students' abilities to behave in…

The purpose of this study was to determine whether there were significant differences in the academic achievement of children attending three different types of school: a model "open" school, a comparable "traditional" school, and a traditional school with a student population from a higher socioeconomic area. Data based on…

The Modern Language Aptitude Test (MLAT) was part of a project examining biographical, motivational, attitudinal, personality, and cognitive aptitude variables in 1,000 adult students preparing at the Foreign Service Institute for overseas assignments, with various subsamples completing different instruments. Data were analyzed using correlation,…

In order to better understand contributing factors of moral judgment development, gifted youth and college students were compared. Moral judgment development, ACT scores, attributional complexity, and descriptors of personality were assessed among 140 college students and 97 gifted youth. Important distinctions favoring the gifted sample were seen…

The topic of differential diagnosis and its application to the use of the Revised Illinois Test of Psycholinguistic Abilities (ITPA) and Wechsler Intelligence Scale for Children-Revised (WISC-R) is discussed. The theoretical bases for differential diagnosis and the properties of assessment instruments with diagnostic properties are presented.…

Intelligence tests are really only systems of classification of individuals with reference to others. Thus with such classification systems it is impossible to interpret a deficiency reflected by test scores in other than a socio-cultural frame of reference. Some 150 Black and White seventh grade children between the ages of 12 and 14 were…

The several statistical methods described for detecting test bias in terms of various internal features of a person's test performances and the test's construct validity can be applied to any groups in the population. But the evidence regarding groups other than U.S. blacks and whites is either lacking or is still too sketchy to permit any strong…

This study compared the performance of college students completing an advanced-level German language course with that of high school-level candidates on the Advanced Placement (AP) German examination. Successful high school-level AP candidates demonstrated a language competency equal or superior to that of college students who received…

The 7th International Conference on Education Data Mining held on July 4th-7th, 2014, at the Institute of Education, London, UK is the leading international forum for high-quality research that mines large data sets in order to answer educational research questions that shed light on the learning process. These data sets may come from the traces…
