Abstract This study addresses the effects of secondary schools and classes on language achievement in Flanders, Belgium. The results of a three‐level analysis (students within classes within schools) indicate that the group composition at the class level is very important. In classes with a high average initial cognitive ability or a large proportion of girls, the language achievement is higher. These compositional effects are discussed with reference to type ‘A’ and type ‘B’ effects. The analyses show that group composition is more important than educational practices in accounting for differences in language achievement. With whom one is taught has a larger impact than how one is taught. Indications of differential effectiveness of classes related to prior achievement were found, with greater variations in effectiveness between classes for pupils of low prior achievement. 相似文献

It is argued that a crucial requirement in studies of educational effectiveness is the modelling of change or growth in student learning. To illustrate one approach to achieving this end, results are presented from multivariate multilevel analyses of three‐waves of data for three Grade level cohorts of students from a longitudinal study designed to explain variation in elementary school students' progress in literacy achievement. The article provides estimates of the influence of prior achievement and social background factors including ‘critical events’, on students’ progress, examines the extent to which progress can be accounted for by the grouping effects of students within classes and schools over successive years, and provides estimates of the effects of explanatory variables at the student‐and class/teacher‐levels. 相似文献

A tale of two variances: between and within 总被引：2，自引：0，他引：2
J Belsky 《Child development》1986,57(5):1301-1305
In response to Worobey and Brazelton's thoughtful and welcome commentary on my assessment of the effectiveness of a Brazelton-based newborn intervention, 2 points are made. The first is that a healthy difference of opinion exists regarding the effectiveness of such interventions; I view the available evidence as less striking than they, but not as limited as they feel my initial study report implies. The second point of this essay is to provide empirical support for my critics' contention that how an intervention is delivered is as important as the fact that an intervention is delivered. By presenting data excised from my original submission to Child Development, it is shown that variation in parents' interest in, involvement with, and enjoyment of the Brazelton intervention was directly related to the intervention's outcome within the joint mother-father treatment condition--even often controlling for background factors related to engagement of the intervention. It is thus concluded that assessment of the process of intervention is critical to any complete evaluation of an intervention, regardless of the results of experimental-control group comparisons. 相似文献

Preparing competent staff is a critical issue within the camp community. This quasi-experimental study examined the effectiveness of an online course for improving staff competency in camp healthcare practices among college-aged camp staff and a comparison group (N = 55). We hypothesized that working in camp would increase competency test scores due to opportunities for staff to experientially apply knowledge learned online. Hierarchical linear modeling was used to analyse the cross-level effects of a between-individuals factor (assignment to experimental or comparison group) and within-individual effects of time (pre-test, post-test #1, and post-test #2) on online course test scores. At post-test #2, the difference in average test scores between groups was ~30 points, with the treatment group scoring lower on average than the comparison group. Factors that may have influenced these findings are explored, including fatigue and the limited durability of online learning. Recommendations for research and practice are discussed. 相似文献

Although group project concepts and skills have become a major component in most information systems (IS) academic programs, very little research has attempted to examine factors that may improve or undermine effectiveness of IS group projects. Accordingly, based on relevant literatures, this study develops and empirically tests a model of factors affecting IS group project effectiveness. The research model posits that group cohesion and group efficacy will have positive effects on group effectiveness (project success and expected impact), whereas perceived loafing is expected to have a negative effect on IS group effectiveness. Data collected from 104 students working in 29 groups to complete semester‐long projects in two IS courses revealed that group efficacy had positive impact on group effectiveness and perceived loafing demonstrated a partial effect. Contrary to expectations, the impact of group cohesion was nonsignificant. These results could be useful in evaluating groups' potential for success and creating conditions conducive to enhancing effectiveness and success of IS student group projects. 相似文献

ABSTRACT Much research on school effectiveness has been characterised by largely overstated claims and poor modelling. School effectiveness research (SER) has tended to define ‘effectiveness’ in terms of a restricted and often inappropriate range of outcomes, to overlook the issue of curriculum alignment, to be limited by the absence of longitudinal data, and it has often been characterised by unsupported assumptions about the homogeneity of school ‘effects’. SER needs to provide justification for the interpretation of ‘effectiveness’ defined as the unexplained part of performance in a statistical model, and a much clearer conception of why certain relationships exist is required. SER has yet to demonstrate the extent to which differences among schools in their ‘effectiveness’ are really caused by identifiable factors within the school and, more importantly, factors within the school's control; evaluations of school improvement interventions are generally unconvincing in this respect. Repeated findings of ‘correlates’ associated with ‘effectiveness’ (particularly when the strengths of the associations are not reported) are no substitute for a well grounded understanding of the specific mechanisms by which schools have their effects. A number of recommendations for future research are made. 相似文献

Longitudinal data are often collected in waves in which a participant’s data can be collected at different times within each wave, resulting in sampling-time variation that is unaccounted for when waves are treated as single time points. Little research has been reported on the effects of this temporal imprecision on longitudinal growth-curve modeling. This article describes the results of a simulation study into the effect of sampling-time variation on parameter estimation, model fit, and model comparison with an empirical validation of the model fit and comparison results. 相似文献

The Sensitivity of Value-Added Teacher Effect Estimates to Different Mathematics Achievement Measures 总被引：1，自引：0，他引：1
J. R. Lockwood Daniel F. McCaffrey Laura S. Hamilton Brian Stecher Vi-Nhuan Le José Felipe Martinez 《Journal of Educational Measurement》2007,44(1):47-67
Using longitudinal data from a cohort of middle school students from a large school district, we estimate separate "value-added" teacher effects for two subscales of a mathematics assessment under a variety of statistical models varying in form and degree of control for student background characteristics. We find that the variation in estimated effects resulting from the different mathematics achievement measures is large relative to variation resulting from choices about model specification, and that the variation within teachers across achievement measures is larger than the variation across teachers. These results suggest that conclusions about individual teachers' performance based on value-added models can be sensitive to the ways in which student achievement is measured. 相似文献

In this article, the effectiveness of an intervention aimed at the development of reading motivation and reading strategies within problem-oriented learning environments is evaluated. The basic assumption underlying the intervention is that reading should occur in meaningful contexts and that reading and science should be regularly integrated. The intervention challenges pupils to investigate a self-formulated problem, read several books or texts on the topic and report the results of their study. The participants were six experimental third-grade classes and seven comparable control classes. The effects of the intervention were measured using a pretest-posttest control group design. Analyses of covariance were conducted to examine the effects as measured by a standardized Reading Comprehension Test, a Reading Comprehension Questionnaire, a Reading Strategy Test and a Reading Motivation Scale. The results showed the experimental group to outperform the control group with regard to knowledge of reading strategies (Reading Comprehension Questionnaire) and the use of such strategies (Reading Strategy Test). A significant difference in favour of the experimental group was also found for the Reading Motivation Scale. An effect on the standardized Reading Comprehension Test was not found. 相似文献

Information is often tabulated, both for the general public and for students in the classroom. The relative effectiveness of tabulated data and prose for making some aspects of data and co‐variation memorable was investigated. Three types of variable (categoric, discrete and continuous) and various patterns in the data were tested on 94 Year 9 students (13—14 years old). The effect of post‐questions on recall was also studied. Tabulating data was found to be generally superior to embedding it in prose as far as recall of data and co‐variation are concerned. Other factors which particularly affected recall included the pattern in the data and the ability of the student as defined by the school. The type of variable seemed to be less important for these students and the data tested. The post‐questions used here did not enhance recall of data or co‐variation. Some aspects of mental model theory were found useful in explaining the effects. 相似文献

Corbels support the crossbeams of half-through arch bridges. They are prone to cracking easily due to their characteristics and complicated loading conditions. Based on a practical diagnosis of a bridge crossbeam, we bonded steel plates onto bridge corbels to strengthen them. We carried out a numerical analysis on the effectiveness of the reinforcement by using the commercial sof~are ANSYS. The numerical analysis shows that the stresses near the section break increased slightly, but the variation amplitude was small and all the stresses were within an allowable range. The loading test indicates that it is feasible to strengthen the corbel with vertical bonded steel plates. Therefore, the reinforcement is effective and economical. This reinforcement method is suitable for this type of corbel and can be applied in similar cases. 相似文献

Reviews on school effectiveness research in developing countries indicate that between-school variances are much larger than in industrialized countries. Resource input factors appear to have a larger impact in developing countries, while there are relatively few studies that have focused on instructional processes. Results at this level are not very clear at this stage. Local contexts may shape and interact with conditions that are expected to enhance effectiveness. Given the high stakes that are involved and the degrees of existing variation, school effectiveness studies in developing countries have the potential to be at the cutting edge of empirical school effectiveness research in the near future. Integration and application of the knowledge-base in evaluation and monitoring projects by means of school process indicators is seen as the most responsible way to use the research findings for improvement purposes. 相似文献

Most universities today require their students to learn about diversity as a part of their degree. Research has examined the effectiveness of diversity courses at changing attitudes toward groups, focusing on sexism or racism, within psychology and women’s studies disciplines. Given the increasing concern over bias in policing, however, this diversity training may be of importance to the study of criminal justice. The current study aims to examine the effectiveness of a diversity course within a criminal justice program at changing perceptions of groups using a survey based on validated measures of attitudes toward women, homosexuality, and symbolic racism. Change in attitudes between the pre-test and post-test are examined. Results suggest that the course is effective at changing attitudes toward homosexuality, but not race or sex. The results also suggest that these perceptions are dependent on group characteristics. 相似文献

This paper considers data obtained in thirty-one schools by using the 'Life in School' checklist. It discusses the issues arising from using the Bullying Index as a measurement of bullying. These include the extent of the variation found between schools and the much-reduced range found on follow-up in the same school. The possible use of the checklist for benchmarking within groups of similar schools is discussed as well as its prime use: self-monitoring by schools over successive years of the effectiveness of anti-bullying policies. Criteria for success are suggested, which emphasize a focus on groups within the school as a prime target for intervention. 相似文献

Stability and Consistency in Secondary Schools’ Effects on Students’ GCSE Outcomes over Three Years∗
Sally Thomas Pam Sammons Peter Mortimore Rebecca Smees 《School Effectiveness & School Improvement》2013,24(2):169-197
This paper reports the results of a UK study investigating the issue of differential school effectiveness. The size of overall school effects versus departmental differences in effects on 16 year old students’ General Certificate in Secondary Education performance are examined, as well as the internal (within school) consistency of departmental effects across six GCSE subject outcomes and the stability of school and departmental effects across three GCSE cohorts (1990‐1992). A value added approach is adopted, controlling for selected student intake measures (such as attainment at secondary transfer). The findings of multilevel analyses suggest that very few schools perform both consistently (across subjects) and with stability (over time). The implications of the results are discussed in relation to the publication and interpretation of schools’ examination results as well as the use of school and departmental effectiveness measures for school self‐evaluation. 相似文献

This study explores the effectiveness of a cooperative learning (CL) approach, where students work together and elaborate concepts of physics. The group problem‐solving tasks were conceptual questions from physics, where the students had to discuss and provide explanations of some phenomena. The effectiveness of the learning‐in‐groups approach was validated and correlated with working group interactiveness. Two group variables were assigned: the group performance and the group activity. These variables and the subjects' participation variable were correlated with achievement. Discourse analysis revealed variation in the nature of the interactions and information exchange, and the two roles as learners and learning facilitators. In addition, the study provided evidence for some features of cooperative learning that could characterize it as a nonlinear dynamical process. Implications of the findings are discussed. © 2006 Wiley Periodicals, Inc. J Res Sci Teach 43: 556–576, 2006 相似文献

The aim of this study was to test the validity of Creemers' model of educational effectiveness in relation to different criteria of measuring effectiveness. It was also examined whether the variables “personality” and “thinking style” could be included in Creemers' model. Achievement in mathematics, Greek language, and affective aims of schooling were measured at the beginning and at the end of school year 2001?–?2002. Data on most of the variables included in Creemers' model were collected through external observations and questionnaires to students, teachers, and headteachers. Most of the variables of the model showed the expected effects, irrespective of the criterion used to measure effectiveness. The inclusion of the variables “personality” and “thinking style” significantly improves the explained percentage of achievement variation in each outcome measure. Implications for the development of both generic and differentiated models of educational effectiveness are drawn. 相似文献

Student and faculty perceptions of teaching effectiveness 总被引：1，自引：1，他引：1
Omnibus measures of teaching effectiveness can be viewed as weighted combinations of more narrowly defined traits describing the teaching process. Our study was designed to determine whether students and faculty weight such traits differently in forming their respective perceptions of effective teaching.Students and faculty within the School of Business and Economics at CSUN were surveyed regarding their assessment of ideal teaching effectiveness in courses where the predominant mode of presentation is lecture. Ten traits depicting various aspects of teaching were selected and each respondent was asked to distribute 100 points across the 10 according to their view of each trait's relative importance in determining effectiveness. The results indicate that there are, indeed, significant differences in student and faculty assessments.Regression analysis of individual trait weighting on demographic variables such as age, sex, field of specialization, etc., produced generally low, insignificant coefficients of determination for both students and faculty. This observed invariance of the respective perceptions of each group across differing combinations of demographic characteristics provides evidence that students and faculty adopt fundamentally different criteria in evaluating teaching effectiveness. 相似文献

Despite official endorsement of attachment principles in nursery work, these are often not translated into nursery practice. One possible reason for this is that staff training does not sufficiently address the personal implications and anxieties that children's attachments may entail for practitioners. Working from a psychoanalytic perspective on organisational functioning and group learning, this paper describes action research with a group of nursery heads who participated in a professional development programme designed specifically to explore emotional experience in professional work. The positive evaluations of the programme by heads and their staff are described including examples of experiential learning and of increased staff awareness about, and responsiveness to, the emotional experience of children. However, the research also concluded that sustained effectiveness of the model is likely to be dependent on an ongoing culture of attention to the emotional experience of nursery staff within nursery umbrella organisations. 相似文献

The authors investigated the effectiveness of the Triad Training Model (P. Pedersen, 1994a, 1994b, 2000a, 2000b) on influencing counselor empathy, intolerance for ambiguity, and multicultural competency by using a quasi‐experimental treatment group comparison design. No significant differences among the triad training group and two comparison groups were found. However, the changes in multicultural competency scores within the treatment group were found to be significant. Implications of the findings are discussed. 相似文献
