On Properly Using Technologies to Make E-Learning Effective 5 3. Of course, e-learners are no different from conventional learners in that they learn by first understanding the basics of a concept, reinforce this understanding by relat- ing the concept to similar concepts they already know about, then applying the concept to some problems, and then combining more than one concept and apply- ing them to some problems. As such, it is important that the textual parts of the e- learning contents include well-designed exercises and exams. 4. The e-learning contents should in general include interactive elements [9, 10]. There are various ways to have the e-learners manipulate selected parts of the con- tents, such as rollover (rolling the mouse over designated text or media element to get pop-up text), hot text and click zones (clicking on designated text or media element for further information), drag and drops (clicking on a graphical element to move it to another location), etc. Another type of interaction is exercises or ques- tions at various points in the e-learning contents. They may be simple true/false questions, or multiple-choice questions, or fill-in-the-blanks questions. It is impor- tant that feedback to the answers be given immediately, so as to help the e-learners advance to the next part of the contents. It is best to make the questions and an- swers stimulating by borrowing from the game paradigms, such as the board game. However, interactivity must not detract the e-learners from learning. In other words, simple questions and answers should not be made tedious or gratuitous, or require the use of expensive multimedia files that take a long time to load or play, or lead to technical difficulties. Further, interactivity has to be added in a highly usable and intuitive way [10]. 5. The e-learners can be better engaged or more comfortable with customized learn- ing contents. There are three types of customization: learning media, learning envi- ronment, and content [10]. The customization of the learning media refers to the choice of textual, audio, and visual contents. Even if all media are available, some learners may prefer one over another, depending on personal preferences and/or the nature of the contents. The customization of the learning environment refers to the look and feel of the learning contents, such as the layout, background colors, na- tional languages, themes, etc. The customization of the learning content refers to the ability for the e-learners to select certain parts of the learning contents. In gen- eral, it is difficult and resource-intensive to create multiple versions of the same learning contents for customization. 5 Online Social Networking During the past decade, many social networking sites have emerged to help members form online communities and exchange various types of information of common interest, and opinions on the information. These sites, including MySpace, FaceBook, Bebo, Meebo, Twitter, Friendster, LinkedIn, Cyworld, etc. have signed up, collec- tively, about 200 million members around the world, who join online communities and share their personal profiles and information about events in their lives. There are also information sharing sites, such as YouTube, Flickr, Pandora, Yelp, etc. that have also signed up tens of millions of members who share videos, photographs, reviews on many things (such as local restaurants, bars, stores, hotels and motels), etc., and 6 W. Kim and O R. Jeong form communities to exchange additional information and opinions. Many other Web sites allow visitors to post comments, email contents to others, and even rate them. E-learners may make join some of the social networking sites and information sharing sites for the express purpose of receiving and giving help to other e-learners by joining communities, or special interest groups, and interacting with members of the communities. Further, several of the facilities provided by the social networking sites, information sharing sites, and others, may be adapted to e-learning sites to help e-learners learn more and better. These include the following: 1. a forum for posting and viewing comments on the learning contents, and learning experiences. 2. voting on (i.e., rating) the learning contents. This can help establish confi- dence in such aspects of the learning contents as authority, popularity, con- troversy, etc. 3. saving and organizing lists of learning contents (for future viewing and sharing with “friends”) 4. forming and joining special interest groups. Members of the same interest group can post questions, answers, comments, special announcements, etc. that may help other members learn. 5. sharing learning contents or a saved list of learning contents with other members designated as “friends” or members of common special interest groups. 6. personal files of members, which can help establish the members’ creden- tials with respect to the contents and comments that they may have posted. Beyond these, such sites as Yahoo Scholar allow visitors to contact human experts for answers to particular questions, and Naver have amassed a large collection of answers (provided by paid staffers or unpaid visitors) to particular questions by the visitors. Connecting e-learners with human experts online who are willing to answer questions on specific subjects can similarly be helpful to the e-learners. 6 Concluding Remarks Self-paced e-learning offers some major advantages over the traditional in-class learn- ing, and its importance is certain to grow. However, the designers and creators of e- learning contents must never forget that e-learning is first and foremost about learning, not about technology. There are four types of technologies that can help make e- learning more effective and more enjoyable than it is today. These include technologies that can be used to create and view textual contents, those that can be used to create visual and audio contents, those that can help engage the e-learners, and those that can help the e-learners to form learning communities. In this paper, we examined how each of these technologies can be used to help e-learners learn more effectively, and also examined some of the problems that bad uses of technologies may create. It takes con- siderable thought, investment of time, and investment in technologies to make e-learn realize its full potential. We hope our work will serve as useful guidelines for the de- signers and creators of e-learning contents.

E-learning can be viewed as an innovation in information technology (IT) and learning. The Technology Acceptance Model (TAM) has previously received significant attention in the IS research field. The Perceived Character- istics of Innovating (PCI) antecedents of technology adoption decisions have not been widely researched empirically. This study explores students’ percep- tions of utilizing the e-learning website in their decision processes. This work also identifies which model supports a more explanation of variance in the e- learning context. Both TAM and PCI antecedents are investigated in the same context of an e-learning website. Experimental results demonstrate that the PCI constructs explain slightly more variance in users’ intentions of continued use than TAM antecedents. The PCI adoption model provides increasingly rich in- formation concerning the continued use of e-learning website.

E-learning is defined as education delivered, or learning conducted, by Web techniques [1] and lets a person learn at a distance over the Internet using technology. This process en- ables a learner to learn at any time at any place, and is often called online learning [31]. This novel learning method provides an alternative to conventional face-to-face, in- structor-led education [11]. E-learning can be highly personal and interactive, enabling students to attain an intimate out-of-classroom learning style. International Data Corporation (IDC) estimates that the value of the e-learning market worth will be between $21 billion and $28 billion by 2008 [4]. IDC states that the revenue from synchronous e-learning exceeded $5 billion by 2006 [30]. Business spending on e-learning is expected to reach approximately $19.6 billion by 2010, according to IDC [26]. However, the continuous growth of the e-learning market has led to a lack of discussion of individuals’ behavior in the adoption and continued use of e-learning. The Technology Acceptance Model (TAM) has previously received significant at- tention in the IS research field. TAM has become one of the most widely employed Richness Versus Parsimony Antecedents of Technology Adoption Model 9 individual-level technology adoption modes [9]. Perceived ease-of-use and perceived usefulness have played (important roles in affecting technology adoption decisions. The parsimony antecedents of the model are often successfully applied to explain significant variance. Although parsimony the model is very important, individual responses to innovation technologies often depend on the context [9]. For instance, e- learning users are likely to consider whether an innovation can be employed on a trial basis before confirming its adoption. Tornatzky and Fleischer [31] defined innovation as “the situationally new devel- opment and introduction of knowledge-derived tools, artifacts, and devices by which people extend and interact with their environment” (p. 10). E-learning can be treated an information technology (IT) innovation and learning approach innovation for many learners, according to this definition. Based on Rogers’ Innovation Diffusion Theory [28], Moore and Benbasat expended a set of eight Perceived Characteristics of Inno- vating (PCI) antecedents to technology adoption decisions. Little empirical research has tested the constructs of perceived innovation characteristics [3], [9]. Moreover, few previous studies have directly compared the performance of the two models. This investigation explores students’ perceptions of using an e-learning website in their learning processes. As an innovative learning method, the adoption of e-learning involves the adoption of information technology, and changing learning approaches. Therefore, this work also aims to identify the model that most effectively explains variance in the e-learning context. The TAM and PCI antecedents are studied in the same context of the e-learning website. 2 Literature Review 2.1 The Technology Acceptance Model (TAM) The technology acceptance model attempts to explain and predict the determinants of individual behaviour toward a system. The model presents two key beliefs concerning use of technology, namely perceived (usefulness (PU) and perceived ease of use (PEU). Perceived usefulness captures the degree to which a potential adopter regards the target technology as providing value over alternative ways of performing the same task. Ease of use encapsulates the level to which a potential adopter views usage of the target technology as involving little effort [14]. Perceived ease of use is hypothe- sised to be a predictor of perceived usefulness. Additionally, perceived usefulness is postulated to have a direct influence on behavioural intentions to use the technology. The beliefs about using the target system affect usage intentions and behaviour via their impact on a potential adopter’s attitude [5], [14]. Davis, Bagozzi and Warshaw [14] concluded that the internal psychological vari- ables (i.e. the beliefs) that are central to TAM completely mediate the influences of all other variables in the external environment on an individual’s use of an innovation. They observed that ‘external variables…provide the bridge between the internal be- liefs, attitudes and intentions represented in TAM and the various individual differ- ences, situational constraints and managerially controllable interventions impinging on behaviour’ [14]. External variables only indirectly affect usage intentions or usage behaviour [2], [14], [17]. Perceived usefulness and perceived ease of use directly influ- ence on intention to use [22], [29], [35], [36] and technology use [38] across varied organisational contexts and technologies [19]. However, results from TAM-based . an e-learning website in their learning processes. As an innovative learning method, the adoption of e-learning involves the adoption of information technology, and changing learning approaches and better. These include the following: 1. a forum for posting and viewing comments on the learning contents, and learning experiences. 2. voting on (i.e., rating) the learning contents. This.
