Intentional self‐embarrassment

This research explored how and why people intentionally embarrass themselves and how observers react to these embarrassments. Self‐reports prom 566 students at the University of Hawai'i and non‐students indicated that, first, they do intentionally and strategically employ behaviors that cause themselves embarrassment to achieve a variety of goals. Second, self‐embarrassors’ goals affected their tactic choices. Third, embarrassors’ goals were associated with their successful achievement of these goals. Last, the tactics embarrassors used and the goals they attempted affected observers’ responses. Suggestions for modifying existing typologies of embarrassment situations/tactics and goals, as well as limitations and directions for future research are presented.     

幼儿园教师心理健康变迁的横断历史比较

采用横断历史研究的元分析方法,本研究选取1979至2012年间18项采用症状自评量表(SCL-90)的研究报告,分析5826名幼儿园教师在该量表上的得分随年代的变化趋势及相关因素.结果表明:SCL-90各因子均值与年代之间均呈正相关(0.15～0.51),年代可以解释9个因子2％至26％的变异,9个因子均值的增加量为0.06～0.26(效果量d为0.14～0.51),这表明幼儿园教师心理健康问题在缓慢增加;SCL-90中5个因子(躯体化、焦虑、敌对、偏执和精神病性)的标准差与年代呈显著正相关(0.18～0.27),这表明不同幼儿园教师群体在这5个因子上的心理健康水平差异在逐年增大;城市幼儿园教师心理健康水平低于农村幼儿园教师;公办幼儿园教师的心理健康水平低于私立幼儿园教师.     

Customer acceptance of IPTV service quality

The purpose of this article is to provide insights into the effects of Internet Protocol Television (IPTV) service quality and reveal mediation effects in the process of forming the repurchase intention. This study incorporates additional theoretical construct, perceived enjoyment, to reflect IPTV characteristics using extended technology acceptance model (TAM). This study empirically investigated a research model and conducted a survey of IPTV service users. The results of this study are as follows. First, IPTV service quality is summarized as design, security, and customer service, which is supported by second-order factor analysis. Service quality had an influence on perceived usefulness, perceived ease of use, and perceived enjoyment. Second, perceived ease of use had a significant effect on perceived enjoyment, and perceived usefulness also had an effect on repurchase intention. Third, attitude, trust, and satisfaction had a positive effect on repurchase intention. To reveal the impact on repurchase intention of the IPTV service quality, this study proposes customer acceptance on IPTV service based on a modified TAM.     

Exploring students’ perceptions of service-learning experiences in an undergraduate web design course

Service-learning is an experiential learning experience where students learn and develop through active participation in community service to meet the needs of a community. This study explored student learning experiences in a service-learning group project and their perceptions of service-learning in an undergraduate web design course. The data showed that the service-learning project helped students learn the course material, feel more connected to the surrounding community, and improve their communication and problem-solving skills for their careers. The participants appreciated the opportunity to work with the service-learning partner and will be likely to look for more opportunities to get involved in the community. Time constraints, group work, working with real clients, and technical limitations were reported as major challenges in the group project.     

Embellishing Problem-Solving Examples with Deep Structure Information Facilitates Transfer

Appreciation of problem structure is critical to successful learning. Two experiments investigated effective ways of communicating problem structure in a computer-based learning environment and tested whether verbal instruction is necessary to specify solution steps, when deep structure is already embellished by instructional examples. Participants learned to solve algebra-like problems and then solved transfer problems that required adjustment of learned procedures. Experiment 1 demonstrated that verbal instruction helped learning by reducing learners' floundering, but its positive effect disappeared in the transfer. More importantly, students transferred better when they studied with examples that emphasized problem structure rather than solution procedure. Experiment 2 showed that verbal instruction was not necessarily more effective than nonverbal scaffolding to convey problem structure. Final understanding was determined by transparency of problem structure regardless of presence of verbal instruction. However, verbal instruction had a positive impact on learners by having them persist through the task, and optimal instructional choices were likely to differ depending on populations of learners.     

制约成人教育质量的因素及办学实体的选择

提高成人教育的质量是当前急待解决的问题。影响成人教育质量的因素有：缺少观念的引导；发展基础薄弱；成人教育的教师素质偏低和经费投入不足等。解决这些不利因素应从树立明确的素质教育的目标、改进教学方法、提高教师的素质、建立适应成人素质教育的课程结构模式、建立能全面反映学生业绩质量的评价模式以及加强媒体资源的利用和建设等方面入手。     

An Autoethnographical Study of Culture,Power, Identity and Art Education in Post‐Colonial South Korea

This article reflects my experiences of learning art in the 1970s and 1980s and my teaching career in school art education in twenty‐first century South Korea. This autobiographical reflection shows how I have struggled with my identity as an art teacher in the post‐colonial context of Western influences on Korean society since World War II. There has been greater tension and a greater struggle for different values, practices and identities when new values and practices have been introduced into the particular socio‐cultural context of South Korea. My struggles with particular kinds of pedagogic identity valued within the rapidly changing political, economic and cultural context of Western influences on Korean art education demonstrate the hidden structural mechanism of the relationship between culture, power and identity in the post‐colonial world of globalisation. This study as an autoethnographical research provides critical insights into how identities are produced by pedagogic discourses and practices of art education that are constructed through the specific systems of practice and language which transmit and regulate such identities and values.     

Examining barriers in technology-enhanced problem-based learning: Using a performance support systems approach

This study focused on the barriers that middle school teachers faced when implementing technology-enhanced problem-based learning (PBL) in their classrooms. Using a human performance-based model, we interviewed teachers, administrators, university faculty and technical support staff to determine the perceived importance of multiple barriers to the implementation of technology-enhanced PBL. Twenty-one teachers, two school administrators and a project manager, two faculty members, and two technical support staff participated in the study. Interview data were supported by surveys, classroom observations and researchers' reflective journals. Results suggested that lack of a clear, shared vision was the primary barrier. Additional barriers included lack of knowledge and skills, unclear expectations and insufficient feedback. Recommendations to support teachers' efforts to integrate technology-enhanced problem-based learning are presented.     

如何培养大学生英语自主学习能力

目前,大学生英语自主学习能力普遍较低。通过树立新的教育观念、增强英语自主学习意识、创建英语自主学习环境、教会学习策略、建立自主学习中心等途径可以提高大学生英语自主学习能力。
