Behaviour problems in early childhood have a lasting impact on cognitive development and education attainment in later adolescence and into adulthood. Here we address the relationship conduct and hyperactivity problems at school entrance, and vocabulary acquisition in adolescence. We compare performance in identical assessments across two generations of British children born 30 years apart in 1970 (n = 15,676) and 2000/2 (n = 16,628) and find that both conduct and hyperactivity problems have a negative association with later vocabulary in both generations. We take advantage of rich longitudinal birth cohort data and establish that these relationships hold once family socioeconomic status and a child’s personal characteristics and earlier vocabulary acquisition are taken into account. We also find that teenagers today achieved substantively lower scores in the vocabulary assessment compared to their counterparts born 30 years earlier, and that this holds across all categories within each of the family and individual characteristics considered in this article. As vocabulary and language skills are key prerequisites for wider learning, we discuss implications the findings have for education policies.  相似文献

Longitudinal studies offer unique opportunities to identify the specificity variance in the components of a psychometric scale that is administered repeatedly. This article discusses a procedure for evaluation of the relationship between true scale scores and criterion variables uncorrelated with measurement errors in longitudinally presented measures comprising unidimensional multicomponent instruments. The approach provides point and interval estimates of the true scale criterion validity with respect to a criterion that is assessed once or repeatedly, as well as a means for testing temporal stability in this validity. The outlined method is based on an application of the latent variable modeling methodology, is readily applicable with popular software, and is illustrated using empirical data.  相似文献

On‐going attempts by governments to implement measures intended to eliminate environmental degradation in the nearshore waters of the Great Lakes have revealed a critical need for integrative understanding that transcends disciplinary and professional specialisms. Academics from universities in the United States and Canada began, ten years ago, to meet with government officials and with people from nongovernmental organizations to find solutions to the problems in question. Groups of academics followed up these meetings with policy oriented studies using systems and transdisciplinary perspectives. Results have been readily disseminated into a wider constituency of interests because of the participation of nonacademics in the guiding of the studies. Similar collaborative approaches have been used to design role playing exercises for students in environmental studies courses at universities, using various Great Lakes situations as examples. An action learning/research mode lies at the core of environmental education at university level which also has considerable potential for addressing other global issues at universities.  相似文献

The purpose of this study was to investigate the extent to which Lebanese Baccalaureate II students' (Freshmen in american colleges) perceptions of their academic abilities match their actual achievements in both school and government examinations. A population sample of 2999 students were selected from a representative school sample (n = 122) throughout Lebanon. Students' demographic data, occupational choices and perceptions of their achievement were collected by a three-part questionnaire. Their cumulative grade averages in school and in government examinations were standardized and used to assess their career maturity. Findings indicated that most students wanted to become engineers or physicians while their actual achievement scores in school was average and in the government examination below average. Most correlational values between perceptions and actual achievement scores were either negative or insignificant. Students were found to make immature career decisions mainly because of the lack of any formal guidance programs in schools.  相似文献

Higher education in the United States and elsewhere is beset by crises: crises of public confidence, questions of continuing relevance, doubts about continuing the emphasis on doctoral instruction, and a very real financial crisis. In response, governing boards and governmental agencies are devoting increasing attention to the management of higher education. Part of this response has been a heightened interest in formal planning-programming-budgeting-systems (PPBS); in fact, several states have legislated the adoption of PPBS for higher educational planning and decision making. Similar interest has been evidenced in other countries. Therefore, it is an appropriate time to reconsider the nature and role of PPBS and its potential impact on higher education. This paper describes the salient characteristics of PPBS and traces the development of PPBS and related analytical techniques in governmental agencies and institutions of higher education. A second paper will illustrate both the concepts and the implementation of PPBS by a detailed exposition of the University of California's experience with PPBS. Finally, in a third paper we suggest an alternative view of policy analysis for educational planning which is a departure from traditional PPBS. We conclude with general observations and specific recommendations to educational managers seeking to improve their resource allocation procedures.  相似文献

Composite reading scores obtained from parents of 125 reading-disabled children and 125 matched control children who participated in the Colorado Family Reading Study were used to test the validity of self-reported reading problems. Parents who reported that they encountered serious difficulty learning to read had significantly lower reading scores than did those who reported no positive history of reading problems. Moreover, this difference was larger for parents of reading-disabled children than for those of controls. Thus, parental self-reports provide a valid index of reading problems.  相似文献

Counselor education currently does not have a training model that is systematically employed and contains provisions for individual differences or promotes the development of programs for facilitating transfer of training. In the proposed model, counselor educators must decide which of the counseling student's thinking, feeling, and acting behaviors will become the focus of training efforts. The staff creatively implements its conceptualized behavioral curriculum goals through the application of learning principles to specified counseling student behaviors that are assessed to determine if whether or not the desired behavior changes are occurring.  相似文献

The purpose of this investigation was to determine if an instrument, originally designed to classify levels of teachers' questions on the basis of logical operations, could be utilized to measure the level of inquiry present in a classroom discussion and to determine if the inquiry questioning behavior of the teacher influenced student achievement. The results of the study show that the modified classification scheme could accurately and reliably measure the inquiry level of teachers' classroom questions. The data also indicated that teachers who ask a greater proportion of high inquiry questions cause a greater change in students as measured by an achievement examination.  相似文献
