Assessing information quality of e-learning systems: a web mining approach

E-learning systems provide a promising solution as an information exchanging channel. Improved technologies could mean faster and easier access to information but do not necessarily ensure the quality of this information; for this reason it is essential to develop valid and reliable methods of quality measurement and carry out careful information quality evaluations. This paper proposes an assessment model for information quality in e-learning systems based on the quality framework we proposed previously: the proposed framework consists of 14 quality dimensions grouped in three quality factors: intrinsic, contextual representation and accessibility. We use the relative importance as a parameter in a linear equation for the measurement scheme. Formerly, we implemented a goal-question-metrics approach to develop a set of quality metrics for the identified quality attributes within the proposed framework. In this paper, the proposed metrics were computed to produce a numerical rating indicating the overall information quality published in a particular e-learning system. The data collection and evaluation processes were automated using a web data extraction technique and results on a case study are discussed. This assessment model could be useful to e-learning systems designers, providers and users as it provides a comprehensive indication of the quality of information in such systems.     

Learners’ acceptance of e-learning in South Korea: Theories and results

One of the most significant changes in the field of education in this information age is the paradigm shift from teacher-centered to learner-centered education. Along with this paradigm shift, understanding of students’ e-learning adoption behavior among various countries is urgently needed. South Korea’s dense student population and high educational standards made investment in e-learning very cost-effective. However, despite the fact that South Korea is one of the fastest growing countries in e-learning, not much of the research results have been known to the globalized world. By investigating critical factors on e-learning adoption in South Korea, our study attempts to fill a gap in the individual country-level e-learning research.Based on the extensive literature review on flow theory, service quality, and the Technology Acceptance Model, our study proposes a research model which consists of four independent variables (instructor characteristics, teaching materials, design of learning contents, and playfulness), two belief variables (perceived usefulness and perceived ease of use), and one dependent variable (intention to use e-learning). Results of regression analyses are presented. Managerial implications of the findings and future research directions are also discussed.     

Determinants of success for online communities: an empirical study

Although online communities can significantly facilitate collaboration among Internet users, the determinants of success of online communities have seldom been studied empirically. Using the updated DeLone and McLean information systems success model as a theoretical framework, this study proposes a research model to examine the determinants for successful use of online communities. Based on a survey of 165 community members, this study uses structural equation modelling (SEM) approach to investigate the research model. The analytical results strongly support the appropriateness of the research model in identifying the determinants of success of online communities. The analytical results also showed that system quality, information quality and service quality had a significant effect on member loyalty through user satisfaction and behavioural intention to use the online community. Finally, this study discusses the implications of these findings and offer directions for future research.

The relationships among service quality,perceived value,customer satisfaction,and post-purchase intention in mobile value-added services

The purposes of this study are to construct an instrument to evaluate service quality of mobile value-added services and have a further discussion of the relationships among service quality, perceived value, customer satisfaction, and post-purchase intention. Structural equation modeling and multiple regression analysis were used to analyze the data collected from college and graduate students of 15 major universities in Taiwan. The main findings are as follows: (1) service quality positively influences both perceived value and customer satisfaction; (2) perceived value positively influences on both customer satisfaction and post-purchase intention; (3) customer satisfaction positively influences post-purchase intention; (4) service quality has an indirect positive influence on post-purchase intention through customer satisfaction or perceived value; (5) among the dimensions of service quality, “customer service and system reliability” is most influential on perceived value and customer satisfaction, and the influence of “content quality” ranks second; (6) the proposed model is proven with the effectiveness in explaining the relationships among service quality, perceived value, customer satisfaction, and post-purchase intention in mobile added-value services.     

Perceived usefulness,user involvement and behavioral intention: an empirical study of ERP implementation

Many firms have implemented enterprise resource planning (ERP) systems in the past few years. The expensive nature of these systems requires that effective usage of these systems be attained in order for an organization to derive the expected benefits from the technology. This study looks at the influence that perceived usefulness, user involvement, argument for change, prior usage and ease of use have on the behavioral intention to use an ERP system. A mail survey was used to collect data in an organization that was implementing an ERP system. A total of 571 responses were obtained. The results indicate that users perception of the perceived usefulness, ease of use of the technology, and the users’ level of intrinsic involvement all affect their intention to use the technology. The results seem to suggest that managerial efforts aimed at increasing the users’ perceptions of the usefulness and personal relevance of the technology will contribute to implementation success, where success is defined as effectual usage of the technology. The paper ends with possible extensions to this study.     

Modeling the continuance usage intention of online learning environments

This study focused on the continuance usage intention toward online learning environments and also proposed and empirically tested an integrated model to better understand the determinants of students’ continuance intention to use these environments. For this purpose, variables which may have an effect on the continuance usage intention were examined and an “online continuance usage intention model” was revealed. When the variables of the hypothetical model were determined, Technology Continuance Theory, Information Systems Success Model, Cognitive Model and Information Systems Expectation Confirmation Model have been practiced on. Empirical data from 467 public university students who had used an online learning environment for the first time were tested against the proposed research model by using path analysis. The results indicated that, confirmation of the usage of online learning environments could be explained by information quality, system quality and service quality variables. 63% of the variance of the satisfaction variable was explained by information quality, system quality, service quality, confirmation, utilitarian value, outcome expectations and perceived value. Research results confirmed the propounded constructs of Information Systems Success Model and Information Systems Expectation Confirmation Model. In line with the obtained findings and results, some of the various suggestions were provided for the next studies and implementations.     

Perceived usefulness and performance of human-to-human communications on television

A key assumption of future television (TV) environments is that the future TV viewing experiences will be more active and interactive. Currently several TV technologies based on networked computing, e.g., IPTV (Internet Protocol TV) or Mobile TV, have made it possible for people to interact with their TVs, or even with other viewers through their TVs, by allowing them to access additional functions, for example actively participating in a quiz show, instantly sharing other viewers’ opinions and sending or receiving emails while they are watching a TV programme.To ensure uptake of these new TV technologies, it is essential to match the performance of the novel systems to both current TV viewing experiences and future user needs, since the characteristics of the additional tasks that TV viewers will perform will lead to other substantially different TV viewing experiences. This paper reports on the usefulness and performance evaluation of a novel TV-based human-to-human interaction environment, where audiences of a specific TV channel can exchange public and private text messages. It combines the two popular analogies (Internet chat and SMS) and embeds them into the viewers’ TV experience.Our results showed that this TV hosted human-to-human communication environment could integrate well with the current TV viewing experience. This might lead to applications such as TV-based personal messengers and/or live bulletin board community for fans of a specific TV show. They also revealed several issues that need to be addressed in the development of new TV technologies.     

Antecedents of continued use and extended use of enterprise systems

This study examines the antecedents of continued use and extended use of Enterprise Systems (ES). Data were collected from 345 business executives through a self-administered questionnaire survey and are analysed using structural equation modelling (SEM). The results indicate that perceived usefulness, computer self-efficacy, and facilitating conditions are positively related to continued use and extended use of ES. However, neither continued use nor extended use is influenced by subjective norm. Additionally, users’ continued use is significantly related to extended use, and it partially mediates the relationships between extended use and its antecedents. The findings of this study contribute to the existing literature on ES usage behaviour in the post-adoption phase and in the mandatory organisational context. For practice, these findings should give managers a better understanding of the antecedents of ES usage behaviours, which would, in turn, help organisations to develop strategies that encourage their employees to maximise the use of ES in performing their tasks.     

Using SERVQUAL to assess the quality of e-learning experience

Distance learning programs have been dramatically expanding in accordance with demand. Assessment of the quality of e-learning has become a strategic issue, one that is critical to program survival. In this study we propose a modified SERVQUAL instrument for assessing e-learning quality. The instrument consists of five dimensions: Assurance, Empathy, Responsiveness, Reliability, and Website Content. Data analysis from 203 e-learning students shows that four out of these five dimensions (except Reliability) play a significant role in perceived e-learning quality, which in turn affects learners’ satisfaction and future intentions to enroll in online courses. Managerial implications of the major findings are provided.     

The role of perceived organizational support,distributive justice and motivation in reactions to new information technology

Despite tremendous investments in information technology (IT), many technological interventions in organizations fail because employees do not fully accept and use IT. The present study explored how perceived organizational support and distributive justice affect employee reactions to new IT from a motivational point of view. Self-determination theory was used to understand how different motivational styles, varying in degree of self-determination, mediate the relationship of perceived organizational support and distributive justice with reactions to new IT. Results showed that perceived organizational support and distributive justice were associated with intrinsic and identified motivation to use the IT, but only POS was related to enjoyment and acceptance of the IT. Intrinsic and extrinsic motivation were both associated with IT usage, but IT usage was associated with enjoyment and acceptance only when people were intrinsically motivated. Intrinsic motivation also mediated the effects of POS on enjoyment and acceptance. Moreover, intrinsically motivated users were less likely to use a paper-based appointment booking alternative than those who were not. Implications for managing IT implementations are discussed.

Developing a maturity model for service systems in heavy equipment manufacturing enterprises

Heavy equipment manufacturing firms are increasingly challenged by the integration of service planning and execution in their established product-centred information systems (IS) environment. Despite a few standardisation efforts, there is no common understanding of service systems in industry goods companies and the corresponding requirements for the appropriation of information systems. We address this need by developing a maturity model. The design of the model is grounded in extant literature, focus group and case study research involving eleven organisations over 1.5 years. The evaluation confirms that the maturity model makes a novel and useful contribution to the design of service systems.     

Evaluating the value of collaboration systems in collocated teams: A longitudinal analysis

Distributed work structure has increased the importance of group work. Consequently, the usage of collaboration systems that support group work has increased exponentially. However, limited research exists on why collocated group members use collaborative system and how their perceptions about the system change from project initiation to project completion. The study proposes resource management support, coordination support, and evaluation support as key aspects based on which collocated users form beliefs about collaboration system value. Based on technology acceptance model and expectancy disconfirmation theory, we propose a model that examines the evolution of user beliefs from pre to post-adoption stage. Further, we argue that users may engage in different information processing strategies as part of the belief change process. The research model was examined based on longitudinal data collected from student groups working on a software application development project over a three month period. The results show that users deemed all features to be valuable at the pre-adoption stage. However, at the post-adoption stage evaluation support was the only factor that had a direct influence on collaboration system usefulness. While the impact of other support factors was mediated through the confirmation process. Further, users engaged in high information processing in revising their beliefs about collaboration system features, when they experienced a high level of dissonance. On the contrary, a dual information processing approach was visible in the context of support features that required adjustment or update to beliefs from pre to post-adoption stage. The study provides three core areas around which designers can structure collaboration system features to make it more useful. It also provides theoretical insights into the process through which user cognitions about collaboration system value change over time.     

Imaginal and emotional experiences in pleasure-oriented IT usage: A hedonic consumption perspective

Based on the marketing theory of hedonic consumption, this study examines the effects of six types of imaginal and emotional experiences on using pleasure-oriented IT. Associated hypotheses are tested using questionnaire responses from 443 online game players. The results provide strong support for the major hypotheses and indicate that the determinants of behavior may differ in using pleasure-oriented versus productivity-oriented IT. This paper contributes not only to the application of a marketing theory to IS research, but also to improved understanding of using pleasure-oriented IT and of why people use technologies that are not particularly useful from a productivity standpoint.     

Exploring the perceived business value of the flexibility enabled by information technology infrastructure

We developed a multidimensional definition of IT infrastructure (ITI) and applied it in exploring the perceived strategic payoffs of ITI-enabled flexibility. We began by developing a typology of theoretical approaches that can be used to organize the literature and then developed a multidimensional model by conceptualizing how flexibility can be enabled through technical, human, and process elements of ITI and how these are interrelated. We used a resource-based view of the firm and a dynamic capabilities perspective to account for competitive impacts of the flexibility. Finally, we hypothesized on the moderating effects of organizational size and reporting level of the top IT executive. Data collected from 293 IT managers showed that the range of managerial ITI capabilities, which were positively affected by all areas of IT personnel knowledge and skills, was responsible for the competitive impacts of the ITI-enabled flexibility. Multigroup analyses showed that large organizational size or reporting to the CEO reduced the positive effects of the range of managerial ITI capabilities on competitive impacts.     

Management of lifecycle costs and benefits: Lessons from information systems practice

Assessing the economic feasibility of information systems (IS) projects and operations remains a challenge for most organizations. This research investigates lifecycle cost and benefit management practices and demonstrates that, overall, although organizations intend to improve their information technology (IT) management, they squander many opportunities to do so. There are inconsistencies in cost/benefit management practices. Most organizations that integrate operational benefits into investment analyses do not acknowledge operational costs. Planned project goals are seldom formulated in a verifiable or measurable way; there is little structured feedback on individual lifecycle activities, nor co-ordination of various activities. Thus, the attitude towards cost/benefit management appears primarily context-related and incident-driven. A further development of the system lifecycle-based approach is needed to improve IT cost/benefit management theory and practice, because a coherent set of methods is required to assess IT costs and benefits throughout the entire lifecycle.     

Understanding trust and perceived usefulness in the consumer acceptance of an e-service: a longitudinal investigation

E-services remain characterised by uncertainty despite their proliferation. Consumer trust beliefs are therefore considered an important determinant of e-service adoption. However, the research has not yet considered the potentially dynamic nature of these trust beliefs or how early-stage trust might influence later-stage adoption and use. To address this gap, this study draws on the theory of reasoned action and expectation–confirmation theory in a longitudinal study of trust in e-services. We examine how trust interacts with other consumer beliefs such as perceived usefulness (PU) and how these beliefs together influence consumer intentions and behaviours concerning e-services at both the initial and latter stages of use. The empirical context is online health information services. Data collection on a student population occurred during two time periods approximately five weeks apart. The results show that PU and trust are important at both the initial and latter stages in the consumer acceptance of online health services. Consumers’ actual usage experiences modify perceptions of usefulness and influence the confirmation of their initial expectations. These results have implications for our understanding of the dynamic nature of trust and PU as well as their roles in the long-term sustainability of e-services.
