최근 정보화 시대에 발맞추어 나가기 위해서는 학습자의 문제해결력을 함양하기 위한 능력을 기를 수 있는 교육이 이루어져야 한다. 학습과정에서 학습자 스스로 지식을 조작하고 문제를 해결할 수 있는 학습자중심의 자기 주도적(self-directed) 학습이 강조되고 있다. 이러한 학습을 위하여 웹 기반에서의 문제은행 시스템을 이용하여 자기 주도적 학습과 수준별 학습 평가가 가능하도록 시스템을 설계 및 구현하였다. 본 연구에서 제안하는 시스템은 학습자가 스스로 필요한 문제를 출제하여 학습할 수 있으며, 문제출제 형식은 문제은행방식을 이용한 동적 출제방식을 사용하였다. 학습자가 학습 결과를 즉각적으로 확인하여 직접 피드백 할 수 있으며, 다시 풀어보기를 원하는 문제는 오답노트 기능을 통하여 복습할 수 있도록 하였다. 또한 모의고사를 통한 결과분석에 따라 개인별 심화 및 보충학습을 통해 완전학습 목표에 도달할 수 있도록 하였다. 평가 시 한 과목의 편중을 막기 위하여 비율을 설정해놓았으며, 학습통계에서 평균과 자신의 성적을 비교함으로써 철저하게 자신의 위치를 파악할 수 있도록 하였다.

본 논문에서는 웹기반 문제은행의 발전된 모형으로 문제 유형에 따른 학습자의 맞춤형 문제를 제공하는 시스템을 설계하였다. 본 시스템의 최종 목표는 능동적, 자기 주도적 학습을 실현할 수 있는 맞춤형 이러닝을 통해 학습자의 학업 성취도 향상에 있다. 교수자 및 개발자 중심의 이러닝 서비스가 아닌 학습자의 학습 결과에 능동적으로 반영하고 유연한 서비스를 제공하기 위해 문제 유형에 따른 적합한 다음 단계의 문제를 제공함으로써 이러닝의 효율을 극대화 한다. 기존의 고정 출제 또는 무작위 출제 방식에서 탈피하여 개별 학습자의 오답과 문제 유형을 고려하여 문제의 키워드, 선택된 보기의 키워드, 유동적 난이도에 따른 문제 추출 방식을 설계하였다. 이 모델은 보조 학습의 수단으로 문제은행 시스템을 학습자 중심에 근접하여, 융통적이고 효과적으로 개인화된 서비스를 제공한다.

It is making researches in questions selection method for examination in web-based education system. Most questions made for these remote examinations use methods of making questions using fixed questions or randomly using item pools or automatically using degree of difficulty. This paper proposes a new examination questions selection algorithm in web-based education system for engineer test. Generally, Engineer test is characterized by adequate examination questions selection for degree of difficulty and equally between all units. Therefore this algorithm selected examination questions equally well as regards degree of difficulty and distribution between all units. This algorithm providers more effective education examination method as compared with previous algorithm.

The purpose of this study attempted to investigate academic achievement and cooperative ability as problem-based learning to strengthen communication in Spanish courses. 70 learners taking Spanish at A University from September to December, 2021 were divided into an experimental and a control class to examine their academic achievement and cooperate ability. Academic achievement was not statistically significant, but the sub-area of communication was significant as 0.031 (*p<.05) and the cooperative ability of the experimental group, the average was increased, but it was not statistically significant. Based on this study, continuous follow-up research to develop teaching methods and teaching and learning models suitable for strengthening Spanish communication through various learner-centered convergence teaching methods will contribute to fostering talent desired by the 21st century.

There have been a lot of studies on problem based instruction and collaborative learning environment, but there is a lack of the studies on a system that offers a collaborative learning environment for problem based instruction. Thus I developed and applied a collaborative instruction system for web based problem based instruction. The system was comprised of the collaborative instruction room and the problem based instruction room so that the students could solve the problems by groups through collaborative instruction. The developed system was applied to the actual learning. As a result, the system contributed to the students' improvement in academic achievements, drew a high degree of responses from them, and had positive effects on their affective domain.

In this study, we developed Internet Based Problem Solving Learning Model based on difficulty of internet based problem solving teaching and learning. For these, firstly we developed 7 Steps Problem Solving Model applying ICT-EUS into proper step. Next, we developed Internet Based Problem Solving Learning Model reflecting 7 Steps Problem Solving Model and searched an outline and characteristics of support system to apply the model into instruction. The teaching and learning model is composed of four steps of (1) design (2) preparation (3) teaching and learning execution (4) management, and 7 Steps Problem Solving Model is the core of teaching and learning execution step. The 7 Steps Problem Solving Model and Internet Based Problem Solving Learning Model are not for functional use but for general use. In other words they can be used commonly in all subjects.

In this paper, We designed and implemented a web based PBL system for ICT training. We surveyed special qualities and a learning model which have been researched for web based PBL system. According to the result of preceding research, we designed a web based PBL system consisted of teaming guidance, learning subject, collaboration learning, loaming result, help center, bulletin board. Also, We applied the web based PBL system to beginner. According to the result of this application, it was found that the students had more interest in learning and utilization of the system when using the web based PBL system. And the web based PBL system was very useful in setting up a problem-solving plan and a ICT learning plan.
