Even though computer based college lecture management system was developed long ago and has been used ever since, developing perfect lecture management is not simple. The main objective of this system is to develop appropriate online lecture supportive management program suitable for college lectures. This system [ADLEMS] mainly focuses on the management of college database lectures, exams, and grades. This system supports management and grading of attendance, reports, quizzes, mid-term, and final exams. Exam management categorizes into multiple choice questions, essay questions, short answer questions, and SQL. Especially for SQL, division analysis was applied when developing grading system for more effective grade management. For essay questions and short answer questions, manual [hand] grading method was used. Every student can verify the grading process in person to alleviate the problems occurring during the grading process.

It is important to estimate objectively in the driving test. Especially, the driving test is examined by totally driving ability, rule observation and situational judgement. For this, a grading automation system for driving test was presented by using GPS, sensor data and equipment operation informations. This system is composed of vehicle mounted module, automatic grading terminal, data controller, data storage and processing server. The vehicle mounted module gathters sensor data in the car. The terminal performs automatic grading using the received sensor data according the driving test criterion. To overcome the misposition of vehicle in the map due to GPS error, we proposed the automatic grading system by map matching method, path deviation and return algorithm. In the experimental results, it was possible to grade automatically, display the right position of the car, and return to the right path under 10 seconds when the vehicle was out of the shadow region of the GPS. This system can be also applied to the driving education.

In this paper, we introduce an automatic scoring system for middle-school level writing test based on using machine learning techniques. We discuss overall process and features for building an automatic English writing scoring system. A "concept answer" which represents an abstract meaning of text is newly introduced in order to evaluate the elaboration of a student's answer. In this work, multiple machine learning algorithms are adopted for scoring English writings. We suggest a decision process "optimal combination" which optimally combines multiple outputs of machine learning algorithms and generates a final single output in order to improve the performance of the automatic scoring. By experiments with actual test data, we evaluate the performance of overall automated English writing scoring system.

The purpose of this paper is to design, implement and test the automatic marking system for programming languages using key-words and boolean operations to solve the processing problems of natural languages. There are accurate grammar systems and key-words in programming languages. Using these characteristics, We have designed, programmed, and tested automatic marking system for programming languages through key-words and boolean operations in this paper. We have categorized programming languages into 7 types as the type of answer and when a professor input any key-words, the system make him put conjunction with the special character. It can be logical expressions instantly so that the system easily operates. We asked 10 students who are majoring in computer engineering to take a test on the paper and web to show how well automatic marking system that we have programmed works. Then We requested 3 professors if the subject problems marked objectively. As a result, automatic marking system proved to be appropriate. We have proposed the way of using key-words and boolean operation for prohibiting huge natural language processing in marking of subjective question. It promotes efficiency rate of programming, objectivity and speed through the transferal to the web for marking since the system prohibits marker to include personal opinion on marking and gives feedback quickly

본 논문에서는 교육현장에서 서술평평가를 자동화하기 위한 시스템을 제안한다. 제안 시스템은 장문의 응답에서 단어를 추출하여 단어 간 네트워크를 생성하고 정답 네트워크와 비교를 통해 평가를 실시한다. 기존의 키워드 방식은 네트워크 관점에서 노드를 기준으로 채점하는 것이라면, 제안 시스템은 엣지를 기준으로 채점하게 되어 학습자의 답변에서 지식의 관계성을 채점할 수 있어 학습자에게 유용한 피드백을 줄 수 있을 것으로 기대한다.

Practical test items were analyzed to extend the existing scoring method for boat operator licenses to an electronic scoring method. We have attempted to digitize the method within the current practical test system scope and have developed an electronic scoring system using LiDAR sensors and WAVE communication. The results of the study are as follows; the first, the scoring data entered into the LiDAR and examiner score device on the boat were transferred from an integrated processing unit to a land control center through WAVE communication. The system was constructed and verified to store and manage examinee data. Second, when testing the meandering task, accurate distance measurement was achieved by using LiDAR instead of visually observing the stick (3 m), and an accurate distance was displayed through the examiner score device quickly. Finally, we confirmed that it is possible to smoothly transmit and process the WAVE communication used to transfer the score data acquired from the boat to the monitoring center at a high speed without loss.

사이버 교육은 시간과 공간의 제약을 벗어나 각종 멀티미디어 자원을 이용함으로써 기존 교육 방식을 보조하거나 대체하게 되었다. 온라인 학습자들을 평가하고 교육과정을 개선할 수 있는 평가 시스템에 대한 연구는 다양한 교육 컨텐츠에 비하여 부족한 편이다. 본 논문에서는 JSP 와 JDBC 기술을 이용하여 문제 은행 시스템을 설계하였다. 기존의 학습 평가 시스템과는 달리, 데이터 표현을 위하여 XML 언어를 사용하였으며, 객관식 문제의 난이도 조절을 위한 피드백 및 단답형 주관식 문제에 대한 채점방식에 대한 고려를 평가 시스템 설계에 포함하였다. 문제은행은 문항의 형태, 내용, 난이도 등을 포함한 문항의 특성과 관련된 정보들을 체계적으로 저장하여, 보다 정확한 학습 평가 시스템이 되도록 설계하였다.

본 논문에서는 클라이언트/서버 환경에서 교사가 평가 문제를 스스로 관리하는 동시에, 웹 상에서 학생들에게 학습 내용을 테스트하여 학생들의 학습 능력 수준을 손쉽게 파악할 수 있도록 하는 대화형 학생 평가 시스템을 개발하였다. 본 논문에서 구현한 시스템은 과목별 채점 결과를 학급별과 개인별로 통계 처리하여 보여주며, 또한 과목 주제별로 정답 비율을 통계 처리함으로써 학생 개개인 수준을 분석하는데 편리하도록 설계되어 있다. 또한 학생들에게는 웹 상에서 푼 문제에 대한 자신의 채점 결과와 문제 풀이 부분을 즉시 볼 수 있도록 하여 재학습 및 보충학습의 효과를 얻을 수 있도록 하였다. 이로써 교사는 학생 수준에 적합한 교수·학습 방법으로 학생들을 개별 지도할 수 있어 기존의 교사 주도적이고 획일화된 주입식 교육 방식의 문제점을 해결하고자 하였으며, 학생 역시 자신의 수준에 적합한 교육 내용을 제공받을 수 있어 학습 의욕을 향상시킬 수 있다.
