The Early Start Denver Model (ESDM) is an intervention program recommended for pre-schoolers with autism ages 12-48 months. The rationale for this recommendation is the potential for intervention to affect developmental trajectories during early sensitive periods. We investigated outcomes of 32 children aged 18-48 months and 28 children aged…

Purpose: This study examined normative change in children's levels of social competence and parent-child interactions (PCIs) from kindergarten through second grade as well as relations between levels of PCI and children's social development. Methods: Multiple waves of data were collected from parents and teachers of 379 children ranging in age…

Students' use of test information to prepare for a test in a controlled or supervised test environment has been examined in studies outside Australia. This paper reports the findings of the use of test information and its value, in terms of an improvement/decline in marks, in an actual test of an undergraduate subject taught at an Australian…

This research analyzed linked high-quality state data from K-12, adult education, and postsecondary state datasets in order to better understand the association between student demographics and successful completion of a postsecondary program. Due to the relatively small sample size compared to the large number of features, we analyzed the data…

Second language (L2) gains during study abroad have been related to several variables including length of stay (Llanes, 2011), language use (Martinsen, Baker, Dewey, Bown, & Johnson, 2010), and social network development (Isabelli-García, 2006), among others. However, most studies have investigated only a few predictors in single study abroad…

Despite the current importance given to L2 vocabulary acquisition in the last two decades, considerable deficiencies are found in L2 students' vocabulary size. One of the aspects that may influence vocabulary learning is word frequency. However, scholars warn that frequency may lead to wrong conclusions if the way words are distributed is ignored.…

This study examines whether student performance predictors in a numerically based lecture course are similar to those for the web version of the same course. A numerically based course involves quantitative concepts and requires mathematical calculations. Data were collected from students taking a financial management class at a medium sized state…

This research examined how motivation (perceived control, intrinsic motivation, and extrinsic motivation), cognitive learning strategies (deep and surface strategies), and intelligence jointly predict long-term growth in students' mathematics achievement over 5 years. Using longitudinal data from six annual waves (Grades 5 through 10;…

In recent years, schools have tended to eliminate recess period and to devote more time to instruction in order to increase academic achievement. Using a nationally representative sample, this study examined reading scores of students who experienced different numbers of recess days in a week, and different number of times and length of recess in…

This study examined the academic performance of Tech Prep students (referred to as participants) in comparison to non-Tech Prep students (referred to as non-participants) entering a two-year community college from sixteen different high schools in Stark County, Ohio. This study provided a quantitative analysis of students' academic experiences to…

Premises about the effects of early engagement on achievement were investigated with 383 children who were followed from ages 5.5 to 13.5. Change and continuity in behavioral (cooperative-resistant classroom participation) and emotional (school liking-avoidance) engagement were assessed during Grades 1-3 and were examined within variable- and…

Examined age and gender differences in verbal skills and visuomotor skills at kindergarten, in achievement in reading and mathematics at Grade four, and the link between skills at kindergarten and later achievement. Readiness in auditory memory and verbal associations predicted later reading achievement while readiness in number skills and visual…

The value-added model is presented as a method of assessing the impact of treatments in pretest-posttest quasi-experimental designs. The model yields a projection of treatment group performance at posttest time with no special treatment. The difference between the expected result and the actual outcome is "the value added," a measure of…

Teachers and students in the English as a second language classes at the West New York (New Jersey) Adult Learning Center participated in a study to determine which patterns of classroom interaction and student characteristics were most highly related to the acquisition of oral proficiency in English. Differences in teaching styles and…
