The current studies examined the hypothesis that maturity fears are increasing among undergraduate men and women from the United States over time. Study 1 used a time-lag method to assess generational effects of maturity fears among a large sample (n = 3291) of undergraduate men and women assessed in 1982, 1992, 2002, and 2012. Results revealed…

Driving may increase mobility and independence for adolescents with autism without intellectual disability (autism spectrum disorder); however, little is known about rates of licensure. To compare the proportion of adolescents with and without autism spectrum disorder who acquire a learner's permit and driver's license, as well as the rate at…

Multiple imputation (MI), a two-stage process whereby missing data are imputed multiple times and the resulting estimates of the parameter(s) of interest are combined across the completed datasets, is becoming increasingly popular for handling missing data. However, MI can result in biased inference if not carried out appropriately or if the…

Learning implies change. Inside and outside schools, we aim for students to change into people with more skills and knowledge as well as with a growing sense of agency and responsibility. Furthermore, education itself is subject to constant change. In this article, we examine change in 3 case studies in the context of individual music lessons from…

In order to examine the effectiveness of instruction, the authors confront formidable statistical problems, including multivariate structure of classroom observations, longitudinal dependence of both classroom observations and student outcomes. As the authors begin to examine instruction, classroom observations involve multiple variables for which…

Latent class Poisson count models are used to analyse a sample of Danish test score results from a cohort of individuals born in 1954-1955, tested in 1968, and followed until 2011. The procedure takes account of unobservable effects as well as excessive zeros in the data. We show that the test scores measure manifest or measured ability as it has…

The National Center for Educational Statistics, in conjunction with the U.S. Department of Education, compiles statistical data for U.S. schools. As charts indicate, in 2001, it reported that nationwide, 76% of high-income graduates immediately enroll in colleges or trade schools. However, only 49% of Hispanic and 59% of African Americans enroll…

The Los Angeles Unified School District (LAUSD) serves a large majority of socioeconomically disadvantaged students who are struggling academically and are underprepared for high school graduation and college. This article describes the partnership between LAUSD and the Los Angeles Education Research Institute, and how this collaboration endeavors…

This paper presents the findings from a follow-up quantitative analysis of the Community College of Baltimore County's Accelerated Learning Program (ALP). The results suggest that among students who enroll in the highest level developmental writing course, participation in ALP is associated with substantially better outcomes in terms of English…

While Alberta enjoys proven high, world-class results in student achievement, raising high school completion rates is one of the top priorities in improving the provincial education system. The 2011-12 targeted high school completion rate is 82% five years after entering Grade 10--a 2.5% increase from the current average rate of 79.5%. The purpose…

Working in some capacity is almost considered de rigueur for tertiary students. The reasons for working and the impact this has on both an individual's ability to complete their studies and on their post-study labour market outcomes are only recently receiving attention. Using the 1995 and 1998 cohorts of the Longitudinal Surveys of Australian…

This support document accompanies the National Centre for Vocational Education Research (NCVER) report "From School to Work: The Role of Traineeships" (ED493902). It contains a comprehensive review of the literature referred to in that report and detailed descriptions and results of the econometric modeling upon which the findings are…

The problem of choosing the most efficient design (longitudinal, mixed longitudinal, or cross-sectional) to estimate polynomial parameters for time-structured data in educational and psychological research is considered. The comparison of efficiencies shows that the assumed degree of the polynomial is crucial for selecting the most efficient…

The purpose of this study was to investigate if there were differences in the levels of pedagogical knowledge and skills as perceived by the student teachers who were enrolled in the Primary and the Secondary Post Graduate Diploma in Education programme at the National Institute of Education in Singapore. 170 Primary and 426 Secondary student…

Missing data for a given cohort of students in a longitudinal study occurs for at least two reasons: either the student has moved or otherwise become unavailable for testing, or the cohort was not in the testing range at a given testing time. A developmental sampling for time of testing x cohort x grade research plan of testing is used to…
