본 논문에서는 대규모 국가기술자격 종합관리시스템 구축 및 운영에서 중요한 관리요소인 상설검정체계가 안정성과 시스템부하 측면에서 불안요소를 가지고 있는바, 최대 효율성과 안정성을 기반으로 WBT(Web-based test)와 CBT(Computer-based test)의 장점만을 혼용한 WCBT시스템을 설계하고 구현하였다. 제안된 시스템의 성능평가를 위하여 기본적 시뮬레이션으로 파일럿시스템에서 제안 기술을 적용하여 검증 한 후 대한상공회의소 실시간 국가기술자격 시험에 적용한 결과 안정성이 입증되어 지방상공회의소까지 지속적으로 확대할 계획이다. 제안 시스템은 해외자격시험에서 자주 발생되는 통신장애 문제를 근본적으로 해결하였으며 시스템부하 측면에서 최대 효율성을 보여주었다. 본 논문에서 설계 및 구현한 WCBT 서버 및 클라이언트시스템은 운영자 및 시험 감독자의 관리체계와 편리성에서도 좋은 평가를 도출하였다.

This article begins by exploring recent developments in the use of the world wide webs in language testing about what a Web-based language test (WBT) is and how they are used in language testing. After a brief review of computer-based testing, WBTs are defined and categorized as low-tech or high tech. Since low-tech tests are the more feasible, they will constitute the focus of this paper. Next, item types for low-tech WBTs are described, and validation concerns that are specific to WBTs are discussed. After a brief overview of the combination of computer-adaptive and Web-based tests, the general advantages as well as design and implementation issues of WBTs are considered before examining the role that testing consequences play in deciding whether a WBT is an appropriate assessment instrument. It is argued that WBTs are most appropriate in low-stakes testing situations; but with proper supervision, they can also be used in medium-stakes situations although they are not generally recommended for high-stakes situations. Some possible ideas for future research are suggested.(169)

인터넷을 이용한 여러 가지의 서비스 중에서도 학습 진행을 인터넷에서 처리할 수 있도록 하는 시스템에 대한 관심이 늘어나고 있다. 일반적으로 웹을 통한 교육 방식은 단방향적이므로 상호 작용적인 기능을 어떻게 부여할 것인가가 오랫동안 가상 원격 교육의 주제가 되어왔는데, 이 기능은 시험을 통하여 이루어지므로 웹에서의 평가기능이 상당히 중요하게된다. 이에 대한 해결책을 제시하기 위하여 학계와 업체에서 많은 노력을 기울이고 있으며 여러 가지 솔루션이 출현하고 있다. 본 논문에서는 일반적인 문제 출제와 평가를 웹에서 구현하는 방법을 초월하여, 반복적인 문제 풀이 기능을 활용하여 학습 후의 평가 기능보다는 학습 수행 자체의 진행방법의 수준으로까지 활용될 수 있는 도구인 "완전학습기"의 개발과 이를 활용한 결과를 설명하여 웹 기반 교육에서의 새로운 방향을 제시하고자 한다.

Consumers of e-learning market differ from those of other markets in that they are replaced in a specific time scale. For example, e-learning contents aimed at highschool senior students cannot be consumed by a specific consumer over the designated period of time. Hence e-learning service providers need to attract new groups of students every year. Due to lack of information on products designed for continuously emerging consumers, the consumers face difficulties in making rational decisions in a short time period. Increased uncertainty of product purchase leads customers to herding behaviors to obtain information of the product from others and imitate them. Taking into consideration of these features of e-learning market, this study will focus on the online herding behavior in purchasing e-learning contents. There is no definite concept for e-learning. However, it is being discussed in a wide range of perspectives from educational engineering to management to e-business etc. Based upon the existing studies, we identify two main view-points regarding e-learning. The first defines e-learning as a concept that includes existing terminologies, such as CBT (Computer Based Training), WBT (Web Based Training), and IBT (Internet Based Training). In this view, e-learning utilizes IT in order to support professors and a part of or entire education systems. In the second perspective, e-learning is defined as the usage of Internet technology to deliver diverse intelligence and achievement enhancing solutions. In other words, only the educations that are done through the Internet and network can be classified as e-learning. We take the second definition of e-learning for our working definition. The main goal of this study is to investigate what factors affect consumer intention to purchase e-learning contents and to identify the differential impact of the factors between consumers with purchase experience and those without the experience. To accomplish the goal of this study, it focuses on herding behavior and perceived usefulness as antecedents to behavioral intention. The proposed research model in the study extends the Technology Acceptance Model by adding herding behavior and usability to take into account the unique characteristics of e-learning content market and e-learning systems use, respectively. The current study also includes consumer experience with e-learning content purchase because the previous experience is believed to affect purchasing intention when consumers buy experience goods or services. Previous studies on e-learning did not consider the characteristics of e-learning contents market and the differential impact of consumer experience on the relationship between the antecedents and behavioral intention, which is the target of this study. This study employs a survey method to empirically test the proposed research model. A survey questionnaire was developed and distributed to 629 informants. 528 responses were collected, which consist of potential customer group (n = 133) and experienced customer group (n = 395). The data were analyzed using PLS method, a structural equation modeling method. Overall, both herding behavior and perceived usefulness influence consumer intention to purchase e-learning contents. In detail, in the case of potential customer group, herding behavior has stronger effect on purchase intention than does perceived usefulness. However, in the case of shopping-experienced customer group, perceived usefulness has stronger effect than does herding behavior. In sum, the results of the analysis show that with regard to purchasing experience, perceived usefulness and herding behavior had differential effects upon the purchase of e-learning contents. As a follow-up analysis, the interaction effects of the number of purchase transaction and herding behavior/perceived usefulness on purchase intention were investigated. The results show that there are no interaction effects. This study contributes to the literature in a couple of ways. From a theoretical perspective, this study examined and showed evidence that the characteristics of e-learning market such as continuous renewal of consumers and thus high uncertainty and individual experiences are important factors to be considered when the purchase intention of e-learning content is studied. This study can be used as a basis for future studies on e-learning success. From a practical perspective, this study provides several important implications on what types of marketing strategies e-learning companies need to build. The bottom lines of these strategies include target group attraction, word-of-mouth management, enhancement of web site usability quality, etc. The limitations of this study are also discussed for future studies.
