Scoring the constructed responses in large-scale assessments needs great efforts and time to reduce the various types of error in Paper-based training and scoring. For the purpose of eliminating the complexities and problems in Paper and pencil based training and scoring, many of countries including U.S.A and England already have applied online scoring system. There, however, has been few studies to develop the scoring system for the constructed responses items in Korea. The purpose of this study is to develop the basic design of the Internet-based scoring system for the constructed responses. This study suggested the algorithms for assigning scorers to constructed responses, employing methods for monitoring reliability, etc. This system can ensure reliable, quick scoring such as monitor scorer consistency through ongoing reliability checks and assess the quality of scorer decision making through frequent various checking procedures.

Widespread internet service has brought many changes to modern life. Internet installed at school and intra-school computer network presented various education activities such as web-based instruction, immediate evaluation, and management of progress in studying. In this paper an essay question evaluation system for web service is studied for rapid measurement of accomplishment of student. This system provides evaluation of answers consisting a simple sentence and not demanding one word. If an essay question has exactly specified answer sheets and scoring criterion, this system give highly accurate scoring results, which shows nearly the same scoring of a teacher, needs very short time for evaluation, and represents real-time feed back result, so it is expected very high efficiency for the evaluation of an essay question.

본 논문에서는 근거리통신, 인터넷 등의 통신을 이용하여 해당 출제자의 분야별로 출제한 주관식문제를 모든 응시자가 주관식문제의 답을 보내고, 해당 답들을 문제별로 답을 분류한 답, 빈도수, 문제, 해설 등의 채점 정보를 출제자에게 알려주면 출제자는 응시자가 쓴 답들의 종류, 각 답들의 분포, 문제의 해설 등을 참고하여 각 답에 대하여 배점을 결정하고 서버는 이 배점으로 채점한 결과를 출제자에게 보여주는 주관식 답분류 채점시스템에 관한 것이다.

Recently, as the number of Internet users are growing explosively, e-learning has been applied spread, as well as remote evaluation of intellectual capacity However, only the multiple choice and/or the objective tests have been applied to the e-learning, because of difficulty of natural language processing. For the intelligent marking of short-essay typed answer papers with rapidness and fairness, this work utilize heterogenous linguistic knowledges. Firstly, we construct the semantic kernel from un tagged corpus. Then the answer papers of students and instructors are transformed into the vector form. Finally, we evaluate the similarity between the papers by using the semantic kernel and decide whether the answer paper is correct or not, based on the similarity values. For the construction of the semantic kernel, we used latent semantic analysis based on the vector space model. Further we try to reduce the problem of information shortage, by integrating Korean Word Net. For the construction of the semantic kernel we collected 38,727 newspaper articles and extracted 75,175 indexed terms. In the experiment, about 0.894 correlation coefficient value, between the marking results from this system and the human instructors, was acquired.

The existing tutoring estimation systems using the authoring tools or HTML forms on the Web environment don't have been improved inconvenient factors of uni-directional interactive systems. In this paper, we design and implement the interactive tutoring estimation system which is conveniently considered to user on the internet environment. The proposed system is divided into teacher and student modules, which have the functions of the new problem insertion and deletion in database, regular examination marking for the former and lecture/test selection, scoring look, etc for the letter. The environment of server system in this thesis is implemented using the IDC file and SQL database for internet access based on Windows NT, client systems are composed to Windows 95 environment based on Explorer or Netscape to access for interactive tutoring systems.

인터넷의 발달로 온라인 원격강의나 E-Learning 형태의 교육이 많이 확산되었다. 온라인 교육의 확산으로 웹을 기반으로 하는 클라이언트 소프트웨어들이 많이 개발되어 사용되고 있다. 특히 교과목의 특성상 실습위주로 진행되는 프로그래밍 관련 교과목에서는 자동화 된 과제평가 시스템이 필요하다. 프로그래밍 과제평가 시스템에서는 과제제출, 소스코드 업로드, 컴파일 및 실행, 채점, 표절검사 등의 과제평가를 위한 기본적인 작업들을 수행된다. 위와 같은 작업들이 모두 평가시스템 서버에서 진행되기 때문에 서버에 많은 부하가 걸린다. 또한 공정한 평가를 위해 보안이 최우선적으로 고려되어야 한다. 본 논문에서는 스마트 클라이언트 기술을 이용한 과제평가 시스템을 설계하고 구현하였다. 본 시스템에서는 과제평가 시스템의 서비스를 분산시켜 시스템의 부하를 줄이고, 보안을 향상시킴으로써 학생들에게 공정한 평가를 가능하게 하였다.

We have been setting in The age of Ubiquitous that people are able to connect networks whenever and wherever by developing network. We can take any classes anytime we want even right checking out the result of a test through the internet with the spread of networks. The development of net-works has created WBI(Web Based Instruction) which has covered the limit of conservative education for instance, there are some content differences whenever a teacher teaches for each class, it is hard to take a lesson after having a certain period, the process of the class is changed as time goes by and so on. As the study of WBI is actively being worked in this moment, a various of class models are showing and materializing. In WBI, the exiting Objective Checking Assessment is applicable, some of the Performance Assessment which inspects and judges students' actual performance is Working whereas teachers who actually give them points don't have a embodied Performance Assessment Program. In this paper, I will present a Performance Assessment to use conveniently Performance Assessment Program not just students carrying out Performance Assessment using the internet but also teachers dealing with actual administrative works.
