The predictive value for the development of competence of a portfolio as compared with instruments that were easier to administer was studied with 27 government management trainees in the Netherlands. Portfolios were found to be better predictors of workplace performance than were self-rating or peer-rating. (SLD)

Whether boys and girls shared equally in performing behaviors required in hands-on activities in the performance-based science classroom was studied over the school year with 165 students in grades five through eight. Being actively involved predicted students' year-end science attitudes, and boys tended to handle the resources more often. (SLD)

Repeated surveys assessing demographic variables, family relationships, parental behavior, and parent/child characteristics were administered to 664 families and compared with child abuse and neglect data from state records and retrospective self-reports. Analysis found maternal youth and sociopathy predicted general child maltreatment, but…

This article examines the theory and practice of developing futures study for high ability students. It provides a brief history of the development of futures study, examines why futuristic thinking is particularly applicable to high ability students, and discusses specific strategies for developing futuristic thinking. (Contains references.)…

A method for predicting high dental caries increments for children, based on previous research, is presented. Three clinical findings were identified as predictors: number of sound primary molars, number of discolored pits/fissures on first permanent molars, and number of buccal and lingual smooth surfaces of first permanent molars with white…

Criticizes "technologically deterministic" approaches, which seek to extrapolate social change from technological potential. Shows how a three-layer model of component, system, and application technologies can be used to integrate findings from the use and development of technology in specific sectors. Examines three cases of…

Examined significance of PCAT scores, prepharmacy GPA, math and science GPA, and attainment of a previous college degree in predicting first-year pharmacy GPA. Asserts that the best predictive model incorporated all variables, while the most parsimonious model included math and science GPA and the PCAT chemistry subscore. The PCAT was a…

The purpose of the present study is to investigate differential attrition rates in terms of both demographic characteristics and initial levels of child functioning of participants in North Carolina's system of care evaluation. Participants included 303 families (78 dropped out of the study, a 26% attrition rate). Families dropped out of the…

Wilson (1987) and others argue that poor neighborhoods lack important organizational resources the middle class takes for granted, such as childcare centers, grocery stores and pharmacies. However, this approach does not distinguish poor neighborhoods from segregated neighborhoods, ignores immigration and neglects city differences. Using…

This article presents two statistical tasks, one on comparing data sets, another on repeated sampling, both of which have powerful connections to proportional reasoning. Students' work and reasoning on these tasks are included, as well as suggestions for ways to use these tasks with middle school students to connect statistical thinking to…

This paper examines the relationship between the incentives to work and to invest in human capital through education in a lifecycle optimizing model. These incentives are shown to be mutually reinforcing in a simple stylized model. This theoretical prediction is investigated empirically using three large micro datasets covering a broad range of…

Assigning students to different classes on the basis of their achievement levels (tracking, streaming, or ability grouping) is an extensively used strategy with widely debated consequences. The authors developed a model of the effects of tracking on self-concept and interest that integrates the opposing predictions of "assimilation" and…

Are children learning when they are "messing about" in sand or water? Is it science? In a workshop presented at the ASE Annual Meeting in Birmingham (January 2003), "Messy science: planning for learning in the foundation stage," delegates examined the nature of an early years curriculum through first-hand experience of a…

Indices of marital discord and mother-child affective processes were used to predict levels of negativity children displayed with unfamiliar peers. Thirty-nine mothers and their 5-year-olds were observed with 5-7 other mother-child dyads during a 30-minute free play session. Mother and child negativity were coded and two types of marital discord…

At the end of a lecturing period examinations are used to take a snapshot of the level of knowledge of a student. It is essential that this snapshot be taken at the right moment. Particularly when a student fails, it is important to make sure that it is because his level of knowledge is not adequate, not because, for example, he had a severe…
