정보통신 기술의 발전은 교육시스템의 많은 변화를 가져오고 있으며 정보통신 기술을 이용한 학습자의 학습효과를 높이기 위한 많은 연구와 기술들이 적용되고 있다. 그러나 이러한 기술을 이용한 효율적인 교육평가시스템은 부족한 편이다. 현재의 교육평가의 경우 교수자가 기계적으로 학습자의 응답에 대해 정, 오답을 체크하고 단순히 점수화 된 결과만 출력한다. 학습자 오답 응답에 대한 교수자의 적절한 피드백이 잘 이루어지지 않고 있으며, 학습자의 학습곤란 및 학습결손에 대한 정보 취득이 어려운 현실이다. 또한 교수자 자신의 교수방법과 교수 내용 혹은 출제된 문제의 적절성 등에 대한 정보 취득은 어려울뿐더러 많은 시간과 노력이 필요하여 효율적이지 못하다. 본 논문에서는 이러한 비효율적이며 단순 평가의 문제점을 해결하고 교수-학습방법을 개선할 수 있는 평가 시스템을 구현하였다. 난이도와 이원분류를 문제 출제 시 적용하고 그에 따른 결과를 자동으로 분석하는 시스템을 설계하였으며 이러한 평가시스템을 통하여 학습자의 인지도 및 학습장애 등을 정확히 평가할 수 있으며 교수자는 출제된 문제의 적절성과 교수방법 또는 교수 내용 등을 스스로 평가할 수 있다.

This study delineates the process of analyzing the illustrations in high school English I textbook. The goal of this study is to shed light on the issues related to producing better English textbooks. The methods include analysis of the illustrations in the textbook developed under the 2009 Revised National Curriculum and surveys of teachers and students' awareness about them. This study classified common features in the illustrations to devise four analysis criteria: cultural aspects, expression styles, expression techniques, and linguistic functions of the illustrations. The questionnaire was made for both teachers and students. The questions in the survey of teachers were about the relevance to the contents, the layout and formation, learners' interest, cognitive aspects, easiness of teaching and learning, and connectivity with language functions. In the survey of students, familiarity, interest level, learnability, favored expression technique and expression material were considered. The result of the surveys showed that the teachability and learnability are key factors in developing illustrations for English textbooks, and they should look familiar to the students.

This study is a case study designed to create and implement a project-based introduction to nursing science, with the aim of analyzing students' experiences and perceptions following its implementation. The study targeted a total of 95 nursing students at G University in S City who enrolled in the introduction to nursing science course in 2021 and 2022. Data collection took place from September 2021 to December 2022, and data analysis involved examining reflective journals submitted by students after completing the project activities, using content analysis. The research results revealed four categories and nine themes. The four categories were 'Making Challenging Studies More Accessible,' 'Engaging and Enjoyable Learning Experiences,' 'Enhanced Teamwork,' and 'Presentation Limitations.' The project-based learning method was found to be effective and applicable in nursing education, demonstrating positive effects on students' attitudes and learning outcomes. However, since the study focused on students from a single university, it is suggested that future research include repeated studies and extend the application to other nursing courses to validate its effects.

If an instruction system understood the interest and activeness of a learner in real time, it could provide some interesting factors when a learner is tired of learning. It could work as an adaptive tutoring system to help a learner to understand something difficult to understand. Currently the area of the facial expression recognition mainly deals with the facial expression of adults focusing on anger, hatred, fear, sadness, surprising and gladness. These daily facial expressions couldn't be one of expressions of a learner in e-Learning. They should first study the facial expressions of a learner in e-Learning to recognize the feeling of a learner. Collecting as many expression pictures as possible, they should study the meaning of each expression. This study, as a prior research, analyzes the feelings of learners and facial expressions of learners in e-Learning in relation to the feelings to establish the facial expressions database.
