A quantitative synthesis of the results from 66 studies indicated that boys' and girls' science achievement is positively related to affect, but the relationship is weaker than expected. Science achievement correlates more strongly with cognitive abilities than with affect. (Author/BW)

The study used three response-latitude format methods of Lerner et al. (1974) along with the item and forced-choice procedures of Lerner and Knapp (1976) to adequately ascertain the method independence of racial attitude assessment, and to ascertain appropriate inferences to be made about the structure of such attitudes in White adolescents.

Article investigated the stability of both the Edwards Personal Preference Schedule (EPPS) (Edwards, 1959) and the Guilford-Zimmerman Temperment Survey (GZTS) (Guilford and Zimmerman, 1949) by presenting new data on the intercorrelations of the scales in these tests. (Author/RK)

This article looked at non-experimental data via an ordinary least squares (OLS) model and compared its results to ridge regression models in terms of cross-validation predictor weighting precision when using fixed and random predictor cases and small and large p/n ratio models. A majority of the time with two random predictor cases, ridge…

This book looks at quantitative research methods in education. The book is structured to start with chapters on conceptual issues and designing quantitative research studies before going on to data analysis. While each chapter can be studied separately, a better understanding will be reached by reading the book sequentially. This book is intended…

This paper reports on five students' explorations of structural relationships between problem situations that they worked on over several years as participants in a long-term study. In particular, we describe the case of students who recognized isomorphisms between and among two problem situations and who used particular features of the problems…

When low-stakes assessments are administered to examinees, the degree to which examinees give their best effort is often unclear, complicating the validity and interpretation of the resulting test scores. This study introduces a new method for measuring examinee test-taking effort on computer-based test items based on item response time. This…

Beyond some contracted minimum, salaried workers' hours are largely chosen at the worker's discretion and should respond to the strength of contract incentives. Accordingly, we consider the response of teacher hours to accountability and school choice laws introduced in U.S. public schools over the past two decades. Total weekly hours of full-time…

This study examined the relationship between library anxiety and social interdependence. Participants were 115 graduate students from various disciplines who were administered the Library Anxiety Scale (LAS) and the Social Interdependence Scale (SIS). The LAS assesses levels of library anxiety. This instrument has the following five subscales:…

The purpose of the current study was to look at whether a child's activity level was correlated with the level of stress a mother experiences. Parents can describe their children as having distinct and recognizable patterns of behavior as young as in infancy (Paaren, Hewitt, Lemery, Bihun & Goldsmith, 2000). Even at birth, some children are much…

This study investigated the extent of relationships between the motivation-related independent variables of absences and academic self-concept and the dependent variable of academic achievement. A correlational research design was used to measure the extent of association between the study's variables. Participants were 34 11th graders (17 African…

The dispositional motivation of individuals to engage in information processing was studied through an instrument, the Need for Closure Scale (NFCS) (A. Kruglanski and others, 1996), developed to measure differences in the need for structure and closure. One goal of the two studies reported was to address criticisms related to the dimensionality…

This survey, monitoring levels of substance abuse in the United States, serves as a tool for researchers and policymakers to better understand and control substance abuse problems. It provides information on 25,500 participants' use of illicit drugs, alcohol, and tobacco among the civilian, noninstutionalized population. Trends for the years,…

This study investigated the effects of block scheduling on student learning. It compared the grade-point averages (GPAs) of one group of students during their 9th-grade year while under the traditional 7-period day to the GPAs of their 10th-grade year under the 4-by-4 block schedule. The text offers a history of block scheduling and lists some of…

Does student aid increase college attendance or simply subsidize costs for infra-marginal students? Settling the question empirically is a challenge, because aid is correlated with many characteristics that influence educational investment decisions. A shift in financial aid policy that affects some youth but not others can provide an identifying…
