A Comparison of Tests for Equality of Two or More Independent Alpha Coefficients     

Seonghoon Kim  Leonard S. Feldt 《Journal of Educational Measurement》2008,45(2):179-193

This article extends the Bonett (2003a) approach to testing the equality of alpha coefficients from two independent samples to the case of m ≥ 2 independent samples. The extended Fisher-Bonett test and its competitor, the Hakstian-Whalen (1976) test, are illustrated with numerical examples of both hypothesis testing and power calculation. Computer simulations are used to compare the performance of the two tests and the Feldt (1969) test (for m = 2) in terms of power and Type I error control. It is shown that the Fisher-Bonett test is just as effective as its competitors in controlling Type I error, is comparable to them in power, and is equally robust against heterogeneity of error variance.  相似文献   

Informing Culturally Competent Practice Through Cross-Racial Friendships     

Jane E. Atieno Okech  Julia Champe 《International journal for the advancement of counseling》2008,30(2):104-115

International and interdisciplinary literature on cross-racial friendships is critically reviewed as a source of relevant and provocative data for counselling professionals dedicated to multiculturalism. The authors discuss the dynamics of cross-racial friendships and implications for counsellors. Using practical examples grounded by interdisciplinary literature, the authors expand discussions about racism within the counselling profession.  相似文献   

Training reading and phoneme awareness skills in children with Down syndrome     

Kristina Goetz  Charles Hulme  Sophie Brigstocke  Julia M. Carroll  Louise Nasir  M. Snowling 《Reading and writing》2008,21(4):395-412

The authors report a short-term reading intervention study involving 15 children with Down syndrome (DS) who attended mainstream schools. The intervention programme taught children phoneme segmentation and blending skills in the context of learning letter-sounds and working with words in books. The children were taught by their learning support assistants, who received special training for this purpose. Compared to a waiting group, a group of eight children with DS improved significantly on measures of early literacy skills (letter-sound knowledge, Early Word Recognition) following eight weeks of intervention. The waiting group started to make progress once they received the intervention. Both groups maintained progress on the literacy measures five months after the intervention had finished. The results suggest that children with DS can benefit from structured, phonics-based reading intervention.  相似文献

The Global/Local Book Publishing (R)evolution     

Leonard S. Marcus 《Publishing Research Quarterly》2016,32(1):64-69

In the decades since the Second World War, interest in Western-style children’s books has expanded in tandem with the growth of a literacy-minded global middle class. Now, as publishing for young people takes root for the first time in nations as economically and culturally diverse as Mexico, Saudi Arabia, and China, the opportunities for rights exchanges, co-editions, and other forms of industry cooperation across national and cultural borders are greater than ever.  相似文献   

Time and response matching with topographically different responses     

John Hanson  Leonard Green 《Learning & behavior》1986,14(4):435-442

Four pigeons were exposed to several nonindependent concurrent variable-interval schedules of reinforcement. One schedule component required a keypecking response; the other component required a treadlepressing response. The birds matched the ratio of their behavior (as measured by responses and time) between the two topographically different responses to the ratio of reinforcement in those two components. When additional foods not contingent on a keypeck or treadle-press were then added, the birds matched time spent in the components to total rates of food delivered in those components; response matching was somewhat disrupted. The matching law, developed under concurrent variable-interval schedules requiring similar responses, can thus account for choice behavior involving topographically different responses.  相似文献

Operant responding by bonnet macaques for color videotape recordings of social stimuli     

Karyl B. Swartz  Leonard A. Rosenblum 《Learning & behavior》1980,8(2):311-321

Socially reared juvenile bonnet macaques responded at high sustained levels in an operant task for presentation of color videotaped television images of social stimuli. Absolute levels of response depended upon the nature of the stimulus. In two experiments, subjects responded at 60.8% and 74.6% of the 1-h experimental sessions for presentation of a color videotape of a conspecific adult female moving freely in an enclosed stimulus chamber. In a later experiment, subjects maintained high levels of response during 15-min sessions for presentations of the conspecific image, but responded with significantly shorter duration responses for similar presentation of a videotape of an adult female of another macaque species, a still picture of a conspecific adult female, and a videotape of the empty stimulus chamber. With longer, 1-h, stimulus presentation, the three social stimuli sustained high levels of response while responses for presentation of the empty stimulus chamber waned significantly over the experimental session. The sustained high levels of response obtained over several hours of stimulus presentation suggest the value of color videotape stimuli in the experimental study of social perception in nonhuman primates.  相似文献   

Description of Environmental Factors in Schools: Lessons from a Study in North–West Spain     

Julia Crespo Comesa?a  Margarita Pino Juste 《International Review of Education/Internationale Zeitschrift für Erziehungswissenschaft/Revue internationale l'éducation》2007,24(1):205-218

The objective of this study is to offer a view on the different environmental factors that affect health (sound, light, colour, temperature) in the design, planning and organization of school premises. To achieve this, the authors first outline the problems leading to unhealthy situations. They subsequently analyse all the building and planning factors behind those problems based on a study carried out in the Autonomous Community of Galicia, in the north west of Spain. The study took as its subject all secondary-level education centres built in Galicia since the Spanish Basic Act on the Educational System (LOGSE) was passed by the Spanish Parliament in 1990. To conclude, the article offers a number of guidelines to be taken into account when designing a school environment.  相似文献   

Towards graduate employment: exploring student identity through a university-wide employability project     

Sally Smith  Colin Smith  Ella Taylor-Smith  Julia Fotheringham 《Journal of Further & Higher Education》2019,43(5):628-640

Students have expectations of their university education leading to graduate careers, with universities investing considerable resources in institution-wide initiatives designed to enhance opportunities for student work placements and work-related learning. However, there are large variations between courses and disciplines in student uptake of these opportunities, with limited evidence explaining why this might be the case. Recognising recent approaches which consider student identity in transitions, this study explored student attitudes to work-related learning across a range of subject disciplines. The first phase of the study used in-class surveys (N = 199) to focus on students’ self-identification and perceptions of employability initiatives. Follow-up interviews were conducted to further explore themes emerging in the survey data. The study found that, while some students drew on resources for identity work in their recognition of and approach to work-related learning, access was limited, and university resources were not always recognised or effective. The findings have implications for the design of effective graduate employability initiatives.  相似文献
