We studied the effect of the number and characteristics of siblings (sex, age) on school achievement in several grades (kindergarten, first grade, and fifth grade), in two large French cohorts, with more than 16,000 children. Running linear mixed-effects models, we find that, independently of socioeconomic status, having more siblings is…

This article proposes a latent variable regression four-level hierarchical model (LVR-HM4) that uses a fully Bayesian approach. Using multisite multiple-cohort longitudinal data, for example, annual assessment scores over grades for students who are nested within cohorts within schools, the LVR-HM4 attempts to simultaneously model two types of…

We examined whether global instruction of complex akshara and explicit phoneme-level instruction of akshara impact the development of phoneme awareness and its association with akshara knowledge and word reading accuracy. The participants were 100 Sinhala-speaking children from Grades 4 and 5 in Sri Lanka. Phoneme awareness showed stronger growth…

The simple view of reading (SVR) model posits that reading comprehension is a product of decoding and listening comprehension and that reading comprehension difficulties can be categorized according to the weakness and strength of these 2 components. In the present study, I tested the applicability of the SVR to reading comprehension subgroups in…

Federal regulations indicate that the achievement gap must be closed between subgroups, including the gap between special education and non-special education students. We explored the ways in which achievement trends are influenced by three methods of reporting (cross-sectional, cohort-static, and cohort-dynamic). We also investigated (a) the ways…

This report highlights several trends in Oregon that show the correlation between chronic absenteeism and various academic outcomes. Oregon student patterns follow the national trend in that students with better attendance have better outcomes. Fifth-grade chronic absenteeism is a moderately strong predictor of chronic absenteeism in subsequent…

Using data from seven cohorts of language immersion lottery applicants in a large, urban school district, we estimate the causal effects of immersion programs on students' test scores in reading, mathematics, and science and on English learners' (EL) reclassification. We estimate positive intent-to-treat (ITT) effects on reading performance in…

The present study investigated language skills and reading comprehension with English monolingual and Spanish-English bilingual children in grades 2-5. Of the 377 children in the sample, 207 were English monolingual and 170 were Spanish-English bilingual. Data were collected within a cohort-sequential design for two academic years in the fall and…

In school-based randomized control trials (RCTs), a common design is to follow student cohorts over time. For such designs, education researchers usually focus on the place-based (PB) impact parameter, which is estimated using data collected on all students enrolled in the study schools at each data collection point. A potential problem with this…

Content and Language Integrated Learning (CLIL) is a multifaceted educational approach which has emerged as a major innovation in improving language learning and subject learning in the curriculum. In order to analyse the effect of this approach, a number of studies (Dalton Puffer, C., T. Nikula and U. Smit, eds. 2010. "Language Use and…

To explore young adolescents' interest in engineering as a future career, we examined the influence of gender and grade level on participants' (N = 197, aged 10-13) views of engineering. One group (107 students) viewed a brief engineering video and wrote why they felt the same or different about engineering following the video. Qualitative…

Couched in attitude theory, this follow-up study examines children-voiced perceptions of "enjoyment" and "usefulness" toward a "district mandated" elementary physical education (PE) program. Attitudes of 277 5th and 6th grade males and females from four representative schools from within a district were assessed in a…

Summer setback, which is defined as a decline in academic achievement over the summer months, occurs in many academic areas but seems especially problematic in reading. We assessed students from a midwestern parochial school serving predominantly students from a low--socioeconomic status background for their reading achievement before they left…

In this study, we use the US nationally representative Early Childhood Longitudinal Study-Kindergarten Cohort to examine inequalities in opportunities to learn mathematics. Specifically, we examine the characteristics of US students' elementary school math teachers and the instruction they provide. While our findings are consistent with previous…
