In the last decade, the ACT COMP Composite Exam and Objective Test have been the most frequently used standardized measures of cognitive general education outcomes. This article reviews the literature addressing uses of the COMP measures in order to evaluate valid and reliable uses of the COMP measures. It concludes that worthwhile evaluations of uses of the COMP measures can only take place in wellcrafted general education program evaluations, and that many reported general education program evaluations incorporate both untenable assumptions and flawed practices. The article concludes with suggestions for improving general education program evaluations.Donald B. Yarbrough received his B.A. in English literature from Hendrix College, his M.A. in Germanic languages and literature from the University of Kentucky, and his Ph.D. in educational psychology from the University of Georgia. He is currently an assistant professor of educational psychology at the University of Iowa, where he teaches and conducts research in two specialty areas, program evaluation and the cognitive psychology of school learning. This article grew out of an on-going investigation of how best to define and measure the cognitive outcomes of post-secondary general education programs.A portion of this research was presented at the Annual Forum of the Association for Institutional Research, San Francisco, CA, May, 1991.  相似文献

Sixteen fifth-grade teachers and 377 pupils served as Ss in experimental classes. The Torrance Tests of Creative Thinking were used as pretests and posttests and the Childhood Attitude Inventory for Problem Solving was given as a posttest. Eight of the experimental classes used the Purdue Creative Thinking Program (PCTP) for five weeks and eight used the Productive Thinking Program (PTP). Eight teachers used relevant discussion, eight did not; eight teachers were high and eight low in creative ability. Pupils in all conditions made significant gains on verbal and nonverbal originality and nonverbal fluency. Teachers who were low in creative ability had lower means. There were several significant interactions among the three independent variables.  相似文献

Objectives

This study aims to determine the prevalence of maltreatment experienced by institutionalized children prior to their admission to Charitable Children's Institutions (orphanages) in western Kenya, and to describe their socio-demographic characteristics, reasons for admission, and the factors associated with prior experiences of maltreatment.

Methods

A systematic file review was undertaken in five CCIs. Demographic, prior caregiving settings and maltreatment data were extracted. Forms of maltreatment were recorded according to WHO and ISPCAN guidelines. Logistic regression was used in bivariate and multivariable analyses of factors associated with reasons for placement and forms of maltreatment.

Results

A total of 462 files were reviewed. The median (interquartile range) age of children was 6.8 (5.08) years at admission, 56% were male, and 71% had lost one or both parents. The reasons for admission were destitution (36%), abandonment (22%), neglect (21%), physical/sexual abuse (8%), and lack of caregiver (8%). The majority of child and youth residents had experienced at least one form of maltreatment (66%): physical abuse (8%), sexual abuse (2%), psychological abuse (28%), neglect (26%), medical neglect (18%), school deprivation (38%), abandonment (30%), and child labor (23%). The most common reason for non-orphans to be admitted was maltreatment (90%), whereas the most common reason for orphans to be admitted was destitution (49%). Girls (adjusted odds ratio, AOR: .61, 95% CI: .39–.95) and orphans (AOR: .04, 95% CI: .01–.17) were both independently less likely to have a history of maltreatment irrespective of whether it was the reason for admission. Children whose primary caregiver had not been a parent (AOR: .36, 95% CI: .15–.86) and orphans (AOR: .17, 95% CI: .06–.44) were less likely to have been admitted for maltreatment, while children who were separated from siblings were more likely to have been admitted for maltreatment (AOR: 1.62, 95% CI: 1.01–2.60).

Conclusions

The high prevalence of maltreatment prior to admission, particularly among nonorphans, suggests the need for better child abuse and neglect prevention programs in communities, and psychosocial support services in institutions. The significant proportion of children admitted for poverty, predominantly among orphans, indicates that community-based poverty-reduction programs might reduce the need for institutionalization.  相似文献

The effects of human relations seminars on dogmatism scores of educational administration students were investigated. Two groups of graduate students coming largely from the Middle and Far East were used in this study. The experimental group was given a series of human relations workshops over a period of four weeks. The results provided evidence that human relations training can reduce dogmatism as measured by the Rokeach Dogmatism Scale. Also, the seminars provided an opportunity not usually found in the traditional academic program for graduate students to interact with their peers and the faculty.  相似文献

Skating     
Technical evaluation in the sport of figure skating is characterized by a subjective marking system. Figure skating judges are responsible for quickly and accurately discerning the quality of technical elements as well as assigning a score to the overall aesthetic appearance of a performance. Traditionally, overall placement marks are assigned for the entire performance; however, the landing of a jump is widely acknowledged as one of the most critical elements of a skater's program. Therefore, our aims were to identify the biomechanical variables that contribute to technical success in executing landings and to establish whether landings rated as biomechanically optimal are also awarded high technical merit scores by judges. Ten nationally ranked competitive figure skaters were asked to execute on‐ice, double and triple revolution jumps and to try to land the jumps void of technical faults within a calibrated space. Data were collected at 60 Hz using standard three‐dimensional videography. Data reduction was done using the APAS system (Ariel Dynamics Inc). Concurrently, videotapes were viewed and evaluated by 42 accredited judges to determine the perceived technical quality of the landing performances. Judges were asked to evaluate the landing phase of each jump against a landing criteria document. A comparative criteria model was developed to facilitate an assessment of excellence in landing performances through both empirical and subjective analyses. Results of these analyses were twofold: a biomechanical profile of on‐ice landings was obtained, and on‐ice jump landing strategies rated by empirical evaluations were in agreement with judge's perceptions of the same performances.  相似文献

This paper addresses a neglected topic in the knowledge management literature: how the size of a network of actors affects the nature of intra-network social relations and knowledge processes. It makes a theoretical contribution to developing understanding in this area drawing on a range of literatures including practice-based perspectives on knowledge, the literature on the embeddedness of social relations, and relevant knowledge management literature. The central focus of this paper is on the relationship between network size, network density, and how these variables affect intra-network knowledge processes. It suggests that as network size increases network density is likely to decrease (as it becomes problematic for the actors in such networks to retain strong ties with a significant proportion of the network's members), which it will be suggested has significant ramifications for intra-network knowledge processes. This paper concludes by reflecting on the implications of the ideas developed for network-based forms of organizing, and innovation processes.  相似文献
