Conceptualizations of developmental trends are driven by the particular method used to analyze the period of change of interest. Various techniques exist to analyze developmental data, including individual growth curve analysis in observed and latent frameworks, cross-lagged regression to assess interrelations among variables, and multilevel…

This study evaluates the impacts and costs of the Reading Partners program, which uses community volunteers to provide one-on-one tutoring to struggling readers in under-resourced elementary schools. The evaluation uses an experimental design. Students were randomly assigned within 19 different Reading Partners sites to a program or control…

The purpose of this report was to measure the effect of the Baylor College of Medicine Summer Science Institute (BCMSSI) on science performance of students whose teachers participated in the program during summer 2013. Paired t-test results showed statistically significant increases in the BCM students' Stanford 10 science performance at the…

The purpose of this study was to measure the effect of the Baylor College of Medicine Summer Science Institute (BCMSSI) on teacher science content knowledge and students' science performance. The analysis of the effect of participation showed an increase of 253 scale score points on the 2015 State of Texas Assessments of Academic Readiness,…

The purpose of this evaluation was to measure the impact of the Baylor College of Medicine (BCM) Summer Institute on science performance of students whose teachers participated during the summers of 2011 and 2012. Paired t-tests revealed statistically significant increases in a sample of elementary students' Stanford 10 science scores at 3rd…

This study contributes a novel perspective on grade retention by empirically examining how classroom composition relates to the standardized-testing performance of grade-retained students in their post-retained years. This evaluation employed a sample of entire cohorts of urban elementary school children in the Philadelphia School District over 6…

This article investigates the utility of various estimates of mathematics proficiency. The participants were 432 students in Grades 2 through 5. The delayed alternate form reliability of multiskill probes, retention probes, slopes of student growth, and trials to criterion were computed. The fluency probes were found to be both sufficiently…

This study attempted to determine whether certain demographic factors, Intelligence Quotient tests, or achievement tests best predict achievement of second through fourth grade students. Findings suggest that the group mental ability test did not add to the knowledge gained from a comprehensive achievement testing program. (Authors/PP)

A sample of slightly over 1500 students from even numbered grades in public schools in the U.S. Virgin Islands were given the 1973 edition of the Stanford Achievement Test (in grades 2, 4, 6, and 8) and the Test of Academic Skills (in grades 10 and 12) in an attempt to assess student academic achievement in the basic skill areas of mathematics,…

Multivariate statistical analysis determined relationships between scores on the Otis-Lennon School Ability Test and the Stanford Achievement Test at grades 2, 4, and 6 for 272 students. The best predictor of achievement at a later grade was achievement at an earlier grade. Implications are discussed. (SLD)

This study examined scores on second, third and fourth grade reading and mathematics tests to determine the effects of beginning school age on later school success. The analysis involved 352 participants in one rural school district in Western New York. Participants were divided into three groups: (a) age appropriate for entrance to school, (b)…
