The variability effect occurs when learners' exposure to highly variable tasks results in better learning. It was hypothesised that learners who studied high variability worked examples would obtain higher post-test scores compared to learners who studied low variability examples, and learners who self-generated problem solutions for the same high…

In this study, we investigate the growth trajectory of 519 students in a vocational senior high school in Taiwan. The group-based trajectory model identifies 3 subgroups with distinct trajectories of academic achievement in Math and English. This study reveals baseline predictive factors associated with these trajectories as well as relationships…

Research shows that students who double major have higher earnings and are more satisfied with their educational experience in college than those who graduate with a single major. In this study, we examine the extent to which a student's experience with academic acceleration programs in high school, specifically successful participation in the…

PISA 2012 results indicate that school systems that group students based on ability levels tend to have lower performance than those that do not divide students by ability. One way some in the United States have sought to increase equity of opportunity is to mandate enrollment of students in college-preparatory mathematics, i.e., Algebra 1 in…

Building on Shulruf, Hattie and Tumen (2008), this work examines the capacity of various National Certificate in Educational Achievement (NCEA)-derived models to predict first-year performance in Biological Sciences at a New Zealand university. We compared three models: (1) the "best-80" indicator as used by several New Zealand…

The performance of Hawaii's students on the College Entrance Examination Board's Scholastic Aptitude Test (SAT) was assessed in the course of a reanalysis of data presented in a 1985 article by E. B. Page and H. Feifs. Separate analyses were conducted on the verbal and math scores used as criterion variables. The predictor variables included the…

The effects of various college preparation programs, aptitude scores, and student background characteristics on college retention were studied. The data were obtained from the National Education Longitudinal Study: 1988-2000 and NELS:88/2000 Postsecondary Education Transcript Study. The effective sample contained 4,445 first-time freshmen students…

The question of whether a new eligibility ruling will prevent 78 student-athletes in Iowa from receiving athletic scholarships was assessed. Four surveys of Iowa high school principals evaluated the effect of eligibility rules based on grade point averages (GPA), standardized test scores, and high school core curriculum requirements. Attention was…

A study followed 445 Wellesley College (Massachusetts) women students matriculating in 1991 through their college years to isolate factors associated with persistence in math and science. Data were gathered through three surveys (at orientation, at the end of the sophomore year, and before graduation) and in focus groups over the 4 years of the…
