The current study explores the potential of the collaborative reflection of the teacher, colleagues, and students in promoting teacher expertise. To this effect, the authors first created a principled set of checklists on six domains of teacher expertise by synthesizing relevant literature. Then they developed protocols for collaborative reflection. These tools were applied to a middle school English teacher’s reflective practice, involving the teacher participating in stimulated recall sessions of her own classes, writing reflection journals, and receiving feedback from her colleagues and students. The results show that collaborative reflection has high potentials for mediating the teacher’s cognitive and affective changes, leading to behavioral ones. This suggests that collaborative reflection, when relevant institutional prerequisites are met, can take an instrumental role in promoting teacher expertise.

This paper examines the effects of student-centered collaborative project programs using digital media for the EFL university students. To compare the effectiveness of a digital storytelling project program (127 students) and a topic-research presentation program (126 students) we used pre- and post-TOEIC English speaking tests. We also administrated a survey on students’ attitude towards their learning, interviewed students and observed the programs. The results showed that there was a significant improvement of the students’ English speaking ability in the two programs. The score of the topic-research presentation program improved more than that of the digital storytelling program. However, the students in the digital storytelling program were more motivated to engage in the collaborative project than those of topic-research presentation program in terms of interest and participation. Based on the results of the two programs, this paper suggests the educational implications for those who want to develop and implement collaborative projects using digital media for the EFL university students.

Information technologies enable new business models to move the idea from traditional services away towards collaborative offerings allowing customers to become active participants in service delivery. Consequently, the capabilities of other customers are chiefly responsible in creating customer experience. Thus, existing customer experience quality models are extended to address today’s market developments.

Multisided platforms (e.g. eBay, Airbnb, Facebook, Apple’s iOS etc.) are marketplaces to facilitate direct interactions between two or more customer or participant groups and enable the value to customers on one side of a platform typically to increase with the number of participating customers on another side (Hagiu, 2014). Platform is a business model to have the more knowledge of its customers and become more networked (Weill & Woerner, 2015). Collaborative consumption platforms (CCPs) are marketplaces to facilitate sharing activities such as the form of renting, lending, trading, bartering and swapping of goods or services based on Möhlmann’s (2015) definition. The rise of information and communications technology (ICT) such as the internet or mobile apps enables an easy access on CCP, which facilitates peers to trade and decrease transaction costs (Möhlmann, 2015). Although CCPs can create better customer experience than traditional business model, there is asymmetric information among peers, which results in lemons. Boudreau and Hagiu (2008) suggested that platforms owners should reduce lemons problems by establishing technical standards and interfaces, rules and procedures, defining the division of tasks, providing support and documentation and sharing information as non-priced instruments. Some attempts have been made in order to demonstrate online service failure or lemons on the web (Holloway & Beatty, 2003). In the Holloway and Beatty’s study (2003), the typology of online service failures has been provided and demonstrated how online retailers could manage their online service failures effectively. The solution to reduce information problems is signaling of trust about quality such as price, adverting, and warranties (Boulding & Kirmani, 1993). Trust in CCPS is to trust in other peers within the platform to share (Möhlmann, 2015). If a CCP cannot control opportunistic behaviors of peers, the peers participating in the CCP can be harmed as well as the CCP will fail to encourage more peers to participate and thus the social value of the CCP may decrease. It is important to understand decision making process of peers in CCPs and consider the motivations to use CCPs and the contexts at the same time. Enjoyment and economic benefits have a direct impact on behavioral intention to participate in CC in the motivation model by Hamari and his colleagues (2015). We suggest the motivatio ns such as enjoyment or economic benefits can be fit by the specific signals of peers in CCPs. The consumers with different motivations to use CCPs can perceive signals for trust differen tly. The more people pursue hedonic value for CCP, the more they tend to make a decision de pending on heuristics rather than elaborate cognitive process. The more people pursue utilitar ian value for CCP, the more they tend to make a decision depending on elaborate cognitive pr ocessing. We conduct two experiments to examine the fit between motivations and signals of CCPs. The interaction effect between motivations to use CCPs and types of signals is investigated through ANOVA test. People to use CCPs for enjoyment have more usage intention when they are exposed by more reviews rather and CCP with low governance power. On the other hand, People to use CCPs for convenience have more usage intention when they are exposed by high review quality and CCP with strong governance power rather than low governance. Social marketers and public policy makers seek to spread CC for the sake of fostering sustainable consumption behavior and promoting public sharing events (Möhlmann, 2015). Sharing and collaborative consumption can be solutions against global warming, rising fuel and raw material prices, growing pollution, and other anticipatable trends (Belk, 2014). CCPs strive to make people participate to create value of their CCPs based external crosseffect by providing various signals for peers with different motivations. Thus public policy makers should foster CCPs rather than encourage people directly to participate. In addition, public policy makers should give CCPs self-regulation that can decide the types of governance and policies to reduce lemons market problems. Our research contributes to the literature on market failures in CCPs by highlighting the importance of the fit between the motivations to use CCPs and signals. Although people have motivation to participate in CC, they are not willing to participate in CCPs without trust of other peers or goods and services. Thus CCPs need to provide peers with proper signals.

This study investigated peer-to-peer interaction during collaborative, computer-mediated reading tasks. Fourteen university EFL students in Korea worked in pairs to complete three gapfill tasks. The transcript data from these tasks were analyzed to determine: (1) how often collaboration occurs during collaborative reading tasks, (2) the ways in which peers help each other, and (3) how successful peers are in resolving the problems they collaboratively pursue. The results showed that each of these aspects of interaction varied among sets of pairs. On average, however, the participants collaborated to jointly solve 75% of the problems they encountered. They also used a range of helping behaviors during collaboration. While the participants correctly resolved nearly half of the problems they attempted, half were incorrectly answered or unresolved. Based on these findings, pedagogical implications are offered, in addition to suggestions for future research into collaborative reading tasks.

To clarify the nature of the effect of collaborative communication on marketing performance, this study draws on the opportunism theory in order to develop a conceptual framework for investigating how a marketer’s opportunism moderates the relationship between collaborative communication and marketing performance. Empirical findings indicate that a marketer’s opportunism negatively moderates the relationship between collaborative communication and customer cooperation performance, whereas it positively moderates the relationship between collaborative communication and financial performance.

This study aims to analyze the process of how Chinese students practice collaborative writing and to figure out whether collaborative writing is useful to Korean language learners for academic purposes. In total, 15 Chinese students of Korean language for academic purposes participated in the research and they were divided into Groups A and B, respectively. Five participants of Group A were individually assigned with writing tasks while ten participants of Group B conducted collaborative writing tasks in pairs. Groups A and B conducted both tasks of a data commentary and an argumentative essay. The result was that fluency and complexity were not significantly different between Groups A and B. However, accuracy was higher in Group B. Accordingly, for students of Korean language in an advanced level, collaborative writing activities did not result in longer texts or more complex linguistic practices but led to more accurate texts. Whether this accuracy will strengthen grammatical knowledge of language students in an advanced level in the long-term is unknown, so follow-up studies are needed.

In this exploratory analysis, we investigate the genesis and the evolution of local food-purchasing networks created and operated by consumers. In details, we describe how collecting and sharing information about food-products can become a central activity for some consumers’ communities and how these communities are starting to play an active role in the food supply chain. We define this community-based food-purchasing model as collaborative food network (CFN), and we analytically describe its characteristics and differences with respect to the traditional and industrialized agrifood supply chain models. A collaborative food network community in Italy, known as GAS (“Gruppi di Acquisto Solidale” – “Solidarity Purchasing Groups”), is introduced as an example of our analytical model. We will use this empirical example to present the strengths and weaknesses of the CFN model.

In this paper, the author devised new decision recommendation ordering method of items attributed by age to improve accuracy of recommender system. In conventional recommendation system, recommendation order is decided by high order of preference prediction. However, in this paper, recommendation accuracy is improved by decision recommendation order method that reflect age attribute of target customer and neighborhood in preference prediction. By applying decision recommendation order method to recommender system, recommendation accuracy is improved more than conventional ordering method of recommendation.

최근 개발된 테이블탑 시스템들은 컴퓨터 게임의 장점을 살리면서 동시에 전통적인 보드 게임 환경을 재현할 수 있는 장점이 있다. 그리고 이러한 시스템들은 사람들이 많이 모이는 장소에서 기존의 테이블 축구나 핀볼 기계 같은 아날로그 게임 시스템들을 대체하게 될 것이다. 하지만 이러한 테이블탑 시스템들은 그 확장성이 제한되기 때문에 여러 사람이 동시에 게임을 즐기는 것이 어렵다. 따라서 더 많은 사용자들이 게임을 함께 즐기고 상호작용에 참여할 수 있는 물리적인 공간과 고해상도 디스플레이 환경을 지원하기 위해서는 테이블탑 시스템의 규모를 유연하게 확장할 수 있어야 한다. 본 연구에서는 여러 개의 단일 타일드 테이블탑 시스템을 서로 동적으로 연결하여 하나의 초대형 통합 시스템을 구성함으로써 보다 확장된 게임 개발을 지원하는 프레임워크를 개발하였다. 본문에서는 기존 테이블탑 환경의 게임 플랫폼 기술들을 살펴 본 후에, 본 프레임워크의 설계 및 개발 내용에 대하여 상세히 설명한다. 그리고 유효성을 측정하기 위한 성능 평가에 대해서 기술한다.
