기존의 대부분 웹기반 문항평가시스템의 경우 CGI나 자바 스트립트를 이용한 너무나 순차적이며 제한된 평가문항들만 제시함으로써 학습에 흥미도가 떨어지고 학습자 주도의 창의적인 학습을 저해하는 요인이 되었다. 본 논문에서는 저작도구 PASS2000의 웹연동 방법을 통하여 학습자가 보다 흥미를 느끼고 학습자 수준에 적합한 동적인 다양한 형태의 평가문항 제시와 학습자가 제시된 문항에 대한 학습후에는 자동채점이 가능하며 즉각적인 결과확인이 가능하도록 하였다. 아울러 학습한 평가문항들을 문항평가지 형태로 출력하여 지속적이고 반복적인 개별화 학습을 할 수 있도록 하였다. 이는 장차 보편화될 원격교육시스템에서 학생들의 학습이해능력을 평가할 수 있는 원격 웹기반 문항평가시스템을 구현하여, 언제 어디서나 시간과 공간의 제한을 받지 않고 학습할 수 있는 체제가 되도록 하는데 있다.

The programming(algorithm) automated assessment system is to evaluate automatically the accuracy and time/space efficiency of user's solution to the problem which is provided. This system gives the immediate feedback of the solution, real-time ranking. So, in the course of data structure and algorithm, we can apply the knowledge which we have learned to the problem solving. Especially, in the basic course of learning the syntax of the programming language, the novice student can learn in easy and fun by solving the simple problem. The university students can understand in the easy way the meaning of asymptotic analysis of algorithm in data structure & algorithm course.

Many studies on algorithm judging system which verifies the correctness and the time efficiency of your program have been underway recently, most of which are on an online judging system focused on programming contests. However this study is mainly about development and application of the judging system based on client-server. Especially, we designed to promote metacognition and motivation which are emphasized in CRESST model, and implemented the total system that consists of the problem, data set, validation program, and user service environments. We applied our system to elementary, middle, and high school students, and We noticed a significant difference of average score between the experimental and control group in posttest and concluded that the teaching method using our system gave the bigger positive effects on programming learning.

The purpose of this study is to suggest practical experience to develop small sized e-Learning system. The system is designed to help lecturers can arrange interface, organize contents, submit examinations and assess learner's score with no professional computing skills. The system has three advantages. First, it reduced implementation period through the use of GUI. Second, it is ordered to be personalized to construct format of the whole interface. Third, it has operational convenience which can be implemented on PC based system. These personalized features are enabling Learning on Demand. Also, there is comparatively low cost and high effectiveness on e-Learning implementation which facilitating quick adoption of e-Learning in its lectures.

Block programming environment, which is represented by Scratch in elementary and middle school programming education, is suitable for learner's characteristics and cognitive level, and is recommended not only for beginners. Transference to the text programming environment after the block programming is essential for understanding the data processing process, understanding the accuracy and efficiency aspects of algorithms, and creating SW activity. In addition, it is presented step by step in the programming curriculum. In this study, developed WithBlock the online evaluation system for the purpose of transference from a block programming to a text programming environment. The developed system can solve the same algorithm problem in both block and text programming environment, and it can be used for elementary and secondary programming education by automatically scoring the written code and providing immediate feedback. In order to applicable to programming education in elementary and secondary surveyed the usability, learning possibility, interest and satisfaction of WithBlock. The results of the survey showed that it can be used for programming education.

This research presents a performance assessment system of which the purpose is to increase the effectiveness of the instruction and learning through the on-the-job superintendent of the instructor, the self-directed learning of the learner, and the interaction between instructors and students. The presented performance assessment system applies the problem-based situated learning of the web-based performance assessment to the production, the execution, the assessment, and the transmission of the test. For the effective administration and learning in the school, we applies the Problem-Based Learning of constructivism and the web-based situated learning of the learning community to the system design. The production of the web-based performance assessment shows that the problem-based and self-directed learning of the assessment are achieved through the web-based automatic production of the performance assessment, and the contextual learning by case-based learning is performed by the production of the template of the performance assessment.
