Purpose: The extant literature suggests that individual differences in speech perception can be linked to broad receptive language phenotype. For example, a recent study found that individuals with a smaller receptive vocabulary showed diminished lexically guided perceptual learning compared to individuals with a larger receptive vocabulary. Here,…

Stratified teaching is an effective method and means to implement teaching students per their aptitude. Domestic and foreign scholars have carried out many experimental and quasiexperimental studies to observe the impact of stratified teaching on students' academic performance, but the results are quite different. So, can stratified teaching…

The purpose of the present study was to extend the model of measurement invariance by simultaneously estimating invariance across multiple populations in the dichotomous instrument case using multi-group confirmatory factor analytic and multiple indicator multiple causes (MIMIC) methodologies. Using the Arabic version of the General Aptitude Test…

Three prominent theories of intelligence, the Cattell-Horn-Carroll (CHC), extended fluid-crystallized (Gf-Gc) and verbal-perceptual-image rotation (VPR) theories, provide differing descriptions of the structure of intelligence (McGrew, 2009; Horn & Blankson, 2005; Johnson & Bouchard, 2005b). To compare these theories, models representing them were…

This dissertation tests a dynamic assessment-based cognitive hierarchy model and attempts to identify mathematical concepts that predict student learning potential on more advanced mathematical concepts using the units from ST Math, a self-paced curriculum, for third, fourth, and fifth grade students. The quantitative analyses compared a…

The study compares the potential effects of a university admission exam model based on program-specific knowledge and an alternative model relying on general study aptitude (GSA) in the context of a strongly stratified educational system with considerable excess of demand over supply of university education. Using results of the "Sonda…

Purpose: To evaluate the learning effects of a deductive language-teaching procedure when teaching a novel gender agreement verb inflection to children with language impairment. Method: Thirty-two 6-8-year-old children with language impairment were randomly assigned to either a deductive (N = 16) or an inductive (N = 16) treatment group. In the…

Nine- and ten-year old good and poor readers read a target sentence, either a word or a pseudohomophone, preceded by incongruous, congruous, or no-sentence context for the pseudohomophones. Results were consistent with the interactive-compensatory model of reading proposed by Stanovich. (FL)

This paper examines and critiques several learning style inventories (LSI) in an effort to find the optimal research instrument for a proposed empirical study of both the quality of courseware and the impact of courseware characteristics on variations of learning effectiveness due to learner characteristics. Five LSIs are examined: (1) Dunn LSI;…

Two experiments were conducted (1) to identify the component processes of language comprehension that draw upon cognitive capacity for their execution, and (2) to determine differences in patterns of resource allocation during integrative processing for good and poor readers. In the first experiment, nine good and nine poor college-age readers…

This large-scale international comparative study addresses changes in students' math- and English-related self-concept of ability, subjective task-value and interest. Australian (N=1,323) and American (N=651) students are from two separate studies with similar designs and samples, in three cohorts spanning grades 7 to 11 in Australia and 7 to 12…

Using data from a sample of 10 colleges at which most students had taken both SAT I: Reasoning Test and SAT II: Subject Tests, the authors simulated the effects of making selection decisions using SAT II scores in place of SAT I scores. Specifically, they treated the students in each college as forming the applicant pool for a more select college,…
