Economies of scale in schooling     

Lawrence W. Kenny 《Economics of Education Review》1982,2(1):1-24

A model of optimal school size is developed which predicts that schools will minimize total costs by operating in a region of increasing returns to school inputs. Two sources of estimates of the economies of scale coefficient emerge from the optimal school size model, and two rich data sets are used to generate estimates of this coefficient. These estimates support the model and are shown to imply sizeable differences in the cost of schooling between urban and rural areas.  相似文献   

Teachers' attitudes toward and knowledge of child maltreatment     

Kenny MC 《Child abuse & neglect》2004,28(12):1311-1319

OBJECTIVE: The purpose of this study was to determine teachers' self-reported knowledge of the signs and symptoms of child maltreatment, reporting procedures, legal issues surrounding child abuse and their attitudes toward corporal punishment. In addition, a factor analysis was performed on the Educators and Child Abuse Questionnaire (ECAQ) (Kenny, 2001a). METHOD: Two hundred teachers, who work in the southeast region of the US in a large, ethnically diverse school system, were administered the ECAQ which contains questions on knowledge concerning: (1) signs and symptoms of child abuse, (2) laws, and (3) procedures for reporting child abuse as well as number of reports filed. RESULTS: Most teachers reported being unaware of the signs and symptoms of child maltreatment, as well as reporting procedures. They also felt administration would not be supportive and were in disagreement with their legal role as mandated reporters. The ECAQ was found to be a reliable measure with four factors: (1) Awareness of signs and symptoms of child abuse, (2) Knowledge of reporting procedures, (3) Attitudes toward discipline, and (4) Seriousness of child abuse. CONCLUSIONS: In general, teachers reported a lack of awareness of the signs of child abuse and reporting procedures, which may affect their ability to report cases of suspected abuse. There is a need for standardized training in child maltreatment for all teachers as well as clear, concise institutional guidelines for reporting child abuse and support for teachers confronted with suspected victims.  相似文献   

“We Need to Come Together and Raise Our Kids and Our Communities Right”: Black Males Rewriting Social Representations     

Lois Weis  Michelle Fine  Tracey Shepherd  Kenny Foster 《The Urban Review》1999,31(2):125-152

This article excavates the voices of urban black males as they speak their name (Belton, 1996) in a society that denies them this right. Based on data gathered in a large-scale ethnographic interview study of urban America, the authors traverse the spoken lives of these men, as they weave stories about neighborhood and state violence, opportunities denied and missed, and the current power of black men's groups in the church. Through their day-to-day lives urban black men challenge social representations about them in racist America, constructing an alternative hegemonic masculinity revolving around relationships, fatherhood, and dignity.Professor of Sociology of Education at the State University of New York at BuffaloCompleted her Ph.D. at the State University of New York at Buffalo and is now a practicing psychologist at Claremont CollegesCurrent graduate student at CUNY  相似文献   

The rhetoric of Kevorkian's battle.     

R W Kenny 《Quarterly Journal of Speech》2000,86(4):386-401

Kenneth Burke's characterization of constitutions effectively describes the customs and values that are lived within a community, and he has well charted the dialectical process which such constitutions undergo when they actually submit to change. In this paper, the totality of thematically-relevant discursive events which arise during periods of constitutional amending are referred to, building from Bitzer, as a rhetorical situation. Using Bitzer alongside Burke, it will be shown that Jack Kevorkian's rhetorical intent, as expressed in his writings and public statements, is distinct from the rhetorical situation to which he has been assigned, illustrating the significant discrepancy between the would-be rhetorical utterances of a speaker and those utterances which have rhetorical impact. The argument will show how Kevorkian's intention to popularize obitiatry contrasts with his public image as a champion of physician-assisted dying.  相似文献   

Enabling the Use of Research Evidence Within Educational Policymaking in Europe     

Janice Tripney  Caroline Kenny  David Gough 《欧洲教育》2014,46(1):55-74

Despite a political climate demanding evidence-informed decision making in education both within individual countries and at the international level, empirically grounded European research in this field is scarce. This paper reports on a European Commission-funded study that sought to identify and analyze different initiatives across Europe aimed at furthering research-informed policymaking in education, one of a number of comparative analyses in this emerging field. The nature and extent of activity in this area is outlined and an analytical framework is developed to assist understanding. Potential reasons for the observed variation among countries are discussed, along with some of the methodological and conceptual challenges involved in undertaking empirical work in this area. Practically, it is hoped that the results of the mapping exercise and the framework provide a platform for further empirical and conceptual research on research use, an area of study that until recently has been largely ignored by education researchers.  相似文献   

Cowboys with cameras: an interactive expedition     

Kenny Robert  Adam Lenz 《British journal of educational technology : journal of the Council for Educational Technology》2009,40(1):119-134

Utilizing the same technologies pioneered by the embedded journalists in Iraq, the University of Central Florida (UCF) teamed up with TracStar, Inc to create a small-scale, satellite-based expedition transmission package to accompany a university film and digital media professor into parts of Utah and the Moab Desert that had a historical significance to American Western Films. The expedition took the group to many locations where scenes from John Wayne and John Ford movies were filmed. Students along on the trip camped out and suffered similar tough conditions as did the original film crews, experienced the wilderness, and participated in lectures and interviews with locals, who supported the films and acted as extras and stunt persons. The project brought a live experience back to the university campus in which students personally interact firsthand with the people, places, things in as real a manner as what the remote travelers encountered.
This article presents details about the experiences of the first implementation of the live broadcasts from the remote desert and the reactions of focus groups to the experience. One group watched archived broadcast, convinced that they were live. Their impressions and reactions were recorded and analyzed and compared to those who were part of a control group. Conclusions and recommendations for future trips are introduced.  相似文献

Abstract

In this study we compared the kinematic features of the throwing motion between young baseball players of different age groups. Forty‐four Japanese baseball players aged 6.1 to 12.3 years who regularly played baseball, including pitchers and position players, had their throwing actions analyzed three‐dimensionally using high speed videography. Of this sample, 26 players aged above 9 years of age were categorized as the senior group, while the remaining 18 were categorized as the junior group. Senior group throwers had greater height and body mass, and produced a greater ball speed than junior group throwers. The throwing arm movement of senior group throwers was similar to that of adult skilled players. However, in the junior group throwers, the shoulder horizontal adduction angle was larger during the arm acceleration phase, and the maximum angular velocities of elbow extension and shoulder internal rotation occurred later than in senior group throwers. These results indicate that players aged above 9 years can acquire a mature throwing arm movement, while players younger than that will use an immature motion. A possible reason why these differences were shown is that the official baseball is relatively heavy for junior group throwers; they would be better advised to use a lighter ball in throwing practice.  相似文献   

Student teachers' attitudes and beliefs towards using ICT within inclusive education and practice     

Nigel Beacham  Kenny McIntosh 《Journal of Research in Special Educational Needs》2014,14(3):180-191

The areas of education inclusion and digital inclusion have recently received growing interest from the research community while addressing the wider concern of social inclusion, but little research has been carried out exploring the relationship between the two areas. Central to both areas, this paper presents a study that investigated student teachers' attitudes towards using Information and Communication Technology (ICT) for equality as part of inclusive education and practice, and explored the extent to which it is important that student teachers are prepared for both education and digital inclusion. The study focused on the attitudes of student teachers who had taken a new reformed course on inclusive education and practice within a Scottish University. Results from the study showed that student teachers' attitudes towards using ICT for teaching and learning were strongly positive, and were also strongly positive towards inclusive education. Their attitudes towards inclusive practice and using ICT for inclusive practice were slightly less positive. This seemed to result in ICT being used less in terms of inclusive education and more from the perspective of accessibility to the curriculum. The study provided evidence that the impact of ICT as part of inclusive practice is not well understood by student teachers and that student teachers' attitudes towards digital equality do not feature highly in inclusive practices. Consequently, greater attention to ways in which ICT is used for inclusive purposes is needed in Initial Teacher Education and in education policies in order to improve student teachers' preparedness for education inclusion.  相似文献   

Intelligent and adaptive tutoring for active learning and training environments     

Claire Kenny 《Interactive Learning Environments》2013,21(2):181-195

Active learning facilitated through interactive and adaptive learning environments differs substantially from traditional instructor-oriented, classroom-based teaching. We present a web-based e-learning environment that integrates knowledge learning and skills training. How these tools are used most effectively is still an open question. We propose knowledge-level interaction and adaptive feedback and guidance as central features. We discuss these features and evaluate the effectiveness of this web-based environment, focusing on different aspects of learning behaviour and tool usage. Motivation, acceptance of the approach, learning organisation and actual tool usage are aspects of behaviour that require different evaluation techniques to be used.  相似文献   

Effect of movement velocity during resistance training on muscle-specific hypertrophy: A systematic review     

Daniel A. Hackett  Timothy B. Davies  Rhonda Orr  Kenny Kuang  Mark Halaki 《European Journal of Sport Science》2018,18(4):473-482

Currently, it is unclear whether manipulation of movement velocity during resistance exercise has an effect on hypertrophy of specific muscles. The purpose of this systematic review of literature was to investigate the effect of movement velocity during resistance training on muscle hypertrophy. Five electronic databases were searched using terms related to movement velocity and resistance training. Inclusion criteria were randomised and non-randomised comparative studies; published in English; included healthy adults; used dynamic resistance exercise interventions directly comparing fast training to slower movement velocity training; matched in prescribed intensity and volume; duration ≥4 weeks; and measured muscle hypertrophy. A total of six studies were included involving 119 untrained participants. Hypertrophy of the quadriceps was examined in five studies and of the biceps brachii in two studies. Three studies found significantly greater increases in hypertrophy of the quadriceps for moderate-slow compared to fast training. For the remaining studies examining the quadriceps, significant within-group increase in hypertrophy was found for only moderate-slow training in one study and for only fast training in the other study. The two studies that examined hypertrophy of the biceps brachii found greater increases for fast compared to moderate-slow training. Caution is required when interpreting the findings from this review due to the low number of studies, hence insufficient data. Future longitudinal randomised controlled studies in cohorts of healthy adults are required to confirm and extend our findings.  相似文献
