A young child’s dialogic appropriation of programmable robots     

Sung Eun Jung  Kyunghwa Lee 《British journal of educational technology : journal of the Council for Educational Technology》2021,52(1):394-410

This qualitative case study explores a 6-year-old boy’s dialogic appropriation of programmable robots. The study was conducted in two robotics education programs for children aged four to seven. Drawing on Bakhtin’s (1981) notion of appropriation, we found that the focal child actively engaged with the programmable robots by (1) transforming the given features of the robots, (2) hybridizing the programming practice with the ordinary practices of his peer culture and (3) constructing his own perspective on the agency of robots and the meaning of programming. We argue that the ways in which the focal child engaged with the programmable robots went beyond mere adoption of the robots but rather took the form of dialog.  相似文献   

Multiple perceptions of children's aggression: Differences across neighborhood,age, gender,and perceiver     

Cynthia Hudley  William D. Wakefield  Brenda Britsch  Su‐Je Cho  Tara Smith  Marlene Demorat 《Psychology in the schools》2001,38(1):43-56

We investigated how overtly aggressive behavior was differentially perceived by two types of perceivers, teachers and peers, as a function of student neighborhood, gender, and grade level. Participants (N= 765) were predominantly African American students in grades 3‐5 recruited from two urban public schools in southern California. The neighborhoods surrounding the two schools differed in levels of identified violent crime and economic levels. Teachers in the community experiencing more violence perceived student behavior to be relatively less aggressive and more similar across genders than did teachers in the less violent community. Peers in the community experiencing more violent crime perceived both boys and girls to be somewhat aggressive, whereas in the less violent community, boys were perceived as aggressive more so than were girls. In general, agreement between teacher and peer perceptions was stronger for boys than for girls. © 2001 John Wiley & Sons, Inc.  相似文献

Referral,enrollment, and completion in developmental education sequences in community colleges   总被引：5，自引：0，他引：5  

Thomas Bailey  Dong Wook JeongSung-Woo Cho 《Economics of Education Review》2010

After being assessed, many students entering community colleges are referred to one or more levels of developmental education. While the need to assist students with weak academic skills is well known, little research has examined student progression through multiple levels of developmental education and into entry-level college courses. The purpose of this paper is to analyze the patterns and determinants of student progression through sequences of developmental education starting from initial referral. Our results indicate that fewer than one half of the students who are referred to remediation actually complete the entire sequence to which they are referred. About 30 percent of students referred to developmental education do not enroll in any remedial course, and only about 60 percent of referred students actually enroll in the remedial course to which they were referred. The results also show that more students exit their developmental sequences because they did not enroll in the first or a subsequent course than because they failed or withdrew from a course in which they were enrolled. We also show that men, older students, African American students, part-time students, and students in vocational programs are less likely to progress through their full remedial sequences.  相似文献   

Early gender test score gaps across OECD countries     

Kelly Bedard  Insook Cho 《Economics of Education Review》2010

The results reported in this paper contribute to the debate about gender skill gaps in at least three ways. First, we document the large differences in early gender gaps across developed countries using a large scale, modern, representative data source. Second, we show that countries with pro-female sorting, countries that place girls in classes with higher than average scores have smaller gender test score gaps, at least in math. Third, we show that the degree of academic tracking is correlated with observed gender gaps across developed countries.  相似文献   

An investigation of teacher impact on student inquiry science performance using a hierarchical linear model     

Ou Lydia Liu  Hee‐Sun Lee  Marcia C. Linn 《科学教学研究杂志》2010,47(7):807-819

Teachers play a central role in inquiry science classrooms. In this study, we investigate how seven teacher variables (i.e., gender, experience, perceived importance of inquiry and traditional teaching, workshop attendance, partner teacher, use of technology) affect student knowledge integration understanding of science topics drawing on previous research. Using a two‐level hierarchical linear model, we analyze year‐end knowledge integration performance of 4,513 students taught by 40 teachers across five states. Results indicate that students of teachers who value inquiry teaching strategies have significantly higher levels of knowledge integration understanding than those of teachers who believe in traditional teaching methods. In addition, workshop attendance and having a partner teacher teaching the same unit in the same school also have a positive impact on students' knowledge integration levels. The results underscore the importance of professional development and collegial support in enhancing student success in inquiry science. © 2009 Wiley Periodicals, Inc.

From learning to development: a sociocultural approach to instruction     

Barohny Eun 《Cambridge Journal of Education》2010,40(4):401-418

Theories of human development and learning provide an essential framework in which to understand the mechanisms involved in the process of formal instruction as a specific form of teaching and learning in the school setting. The sociocultural theory of development, founded on the works of Lev Vygotsky, espouses the view that social interaction among two or more people is the greatest motivating force in human development. Communication, via the use of language, provides one of the most effective means of social interaction. By collaborating toward a common cultural goal, people co‐construct new knowledge by building on each participant's contribution. Based on the main tenets of sociocultural theory, the following eight interrelated principles for instruction are presented, namely, that it should be: mediated; discursive; collaborative; responsive; contextualized; activity‐oriented; developmental; and integrated.  相似文献   

Leaning towards China: Taiwanese Basketball Talent Migration to the PRC     

Wan-Ching Cho  Chih-Fu Cheng  Alan Bairner 《国际体育史杂志》2018,35(12-13):1390-1406

Abstract

This study aims to examine the different influences on Taiwanese basketball migration from 1999 to the present particularly in relation to the specific political relationship between Taiwan and China. Political influence on sports talent migration is well recognized, but has yet to be fully explored. This study contributes to our understanding of sport migration by providing in-depth empirical and analytical insights into the role of political influences, thereby adding to an understanding of the institutional factors that can either impede or facilitate sport labour migration and of the key networks involved in specific migratory processes.  相似文献   

A Preliminary Analysis of the Factors Affecting Satisfaction with the Police Practicum Credit Program in South Korea     

Joon Tag Cho  Hyeonho Park 《Journal of Criminal Justice Education》2018,29(1):137-156

Numerous studies have been conducted about criminal justice internship programs in western countries, but few have addressed similar types of programs conducted in Eastern countries. To fill this gap in the literature, this study preliminarily analyzed the factors affecting satisfaction with the police practicum credit program in South Korea using data collected from 208 participating students and police officers. The results showed that participants were generally satisfied with the program but had different perceptions about each program component. Focusing on the crucial elements affecting overall satisfaction with the program, the study examined the following factors: the curriculum; the period and practice time; the proportion of on-site practice; teaching material; credits; and police officers’ preparedness, attitudes and information offerings. Our results suggest that the curriculum and preparedness of the officers in charge were significant factors affecting the participants’ satisfaction. Based on the findings, implications for policy recommendations are discussed.  相似文献   

Use of NSE/PS2m-transgenic mice in the study of the protective effect of exercise on Alzheimer's disease     

Jun Y Cho  Dae Y Hwang  Tae S Kang  Dong H Shin  Jin H Hwang  Chae H Lim 《Journal of sports sciences》2013,31(11):943-951

In its late stage, Alzheimer's disease results in progressive muscle weakness in the arms and legs. The aim of this study was to determine whether mice expressing the skeletal muscle-specific mutant PS2 gene (a model of Alzheimer's disease) are a useful experimental system to study the protective effect of exercise on Aβ-42 reduction, improvement of behavioural function and changes in metabolic parameters. With this aim in mind, the transgenic mice were subjected to treadmill exercise for 3 months. The results showed that in transgenic mice, but not in normal mice, treadmill exercise resulted in a reduction of Aβ-42 deposits and an improvement in behavioural function, thereby restoring normal concentrations of total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol and triglyceride. Thus, exercise may represent a practical therapeutic strategy for use with human patients with Alzheimer's disease.  相似文献
