The digital textbook project which embarked by the Ministry of Education, Science and Technology has focused on experiments and practices from the school designated by the government. However the previous research about digital textbook provides static interaction models and teaching-learning models analogous to web-based learning based desktop PC even the framework of the digital textbook is based of Tablet PC. This paper provides learning and teaching models for next generation digital textbook which based digital inking techinques for sketcth interface and AR(augmented reality) interactions between teacher and learner. The proposed method of this paper is applied to educational contents and we found positive effect which is supported by statistical experiments. The results of this study in the future and the future development of digital textbooks in effect will be an effective development plan.

This paper describes an in-depth study on the effect of students' writing of a reflection journal on academic achievement in Linux courses. For this purpose, students who took a Linux class were surveyed. Those participants were divided into two groups; an experimental group and a control group. Their academic achievement was compared and analyzed for this study and reflection journal was applied for 6 weeks after middle test. The results suggests that task achievement, expectation, learning persistence, self-efficacy, learning attitude, satisfaction in writing a reflection journal, and subject study were improved for the students who wrote a reflection journal. In addition to this, it suggests that the writing of a reflection journal has a significant effect on academic achievement in Linux subjects. It is meaningful for teaching skill of computer engineering education.

The paradigm of engineering education has evolved from subject-centered learning to student -centered learning. In particular, instructional laboratories can be an essential part of studentcentered learning. The curriculum of instructional laboratories in the departments of materials science and engineering, Yonsei University has been investigated. Student surveys on thecurriculum were also carried out. The curriculum was found to develop after reforming it on the basis of student-centered learning. Student feedback reflects that the new curriculum promoted student's active learning and that student's needs of instructional laboratories were considered in the curriculum.

본 연구는 수학 교사가 수학 교과에 대한 학습부진 학생의 이해와 적절한 교수-학습 방법의 탐색을 위한 기초 자료를 제공하기 위해 두 가지 유형의 질적 자료를 중심으로 자료를 수집하고 심리검사, 일반 학습습관, 수학 학습습관, 수학 교과에 대한 태도 등 4가지 선문지를 사용하여 여고생을 대상으로 부진요인 분석에 그 목적을 두었다. 본 연구에 따르면 대표적인 부진 요인은 의문 해결을 위한 의지 결핍과 장기 기억방법을 알지 못하고 수학교과목 자체를 싫어하는 경향이 있는 듯 하였다. 스스로 수학 문제를 풀 수 없다는 선입감 때문에 해답을 보고 문제를 풀게 되고, 검산을 하지 않는 특성을 보였다. 이들 수학 학습부진 학생들을 지도할 때는 선수학습을 반드시 확인하는 수업을 고려해야 하며, 수학적 의사 소통 능력 등 보다 수학적인 내용과 과정에 대한 후속 연구가 필요하다고 본다.

본 연구는 교양교육에 대한 학습 수요자의 요구와 현재 편성되어 있는 교양교육 교과목들에 대한 차이를 알아본다. 학습 수요자의 다양한 생각들을 SNS를 통해 데이터를 수집하고, 텍스트 마이닝 기법을 이용하여 유용한 정보를 발견하고 시각화 분석을 통해 학습자의 요구를 제시한다. 분석 결과로는 학습자는 교수자와 상호작용 잘되는 수업 방식, 학습자가 참여할 수 있는 수업, 자기주도 학습을 선호하였다. 또한 교양교육 교과목 개설로서는 취업에 필요한 외국어, 자격증 취득이 가능한 과목, 실생활에 적용할 수 있는 실용적인 과목들을 요구하여 실제 균형에 맞게 개설된 교과목과는 차이를 보임을 알 수 있었다.

본 연구에서는 2003년부터 시행된 일본 고등학교 학습지도요령의 수학과 구성과 성격을 연구하였다. 또한, 교육과정상의 확률통계교육의 구성과 성격 및 편제에 대하여 고찰한 결과, 새 교육과정에 따른 교과위주의 교육과정의 구성과 내용 및 편제의 특징은 통합학습시간 신설로 미국식 주제 교육의 도입, 완전학교 주 5 일제실시, 중고 일관교육, 단위제 고등학교학교 신설, 종합 학교의 설치로 설명된다. 확률통계 교육의 내용과 범위는 과거 교육과정과 크게 달라진 점은 없으나, 7교과 분야 가운데 3 교과 부분에 자료 위주의 실용통계계산 교육과 통계소프트웨어교육 강화가 그 특징이다.

현재 대부분의 전공이나 교양 교과목에 관한 교수-설계방법은 연구개발이 많이 되어 왔지만 NCS 직업기초능력 정보능력 교양 교과목에 알맞은 교수-학습 설계법은 미진한 형편이다. 따라서, 본 연구에서는 기존의 교수-설계 방법론을 기반으로 한 정보능력 교과목에 관한 교수-학습 모형의 설계안을 제시하고자 한다.

Clear analysis and diagnosis of various characteristic factors of individual students is the most important in order to realize individual customized teaching and learning, which is considered the most essential function of math artificial intelligence-based digital textbooks. In this study, analysis factors and tools for individual customized learning diagnosis and construction models for data collection and analysis were derived from mathematical AI digital textbooks. To this end, according to the Ministry of Education's recent plan to apply AI digital textbooks, the demand for AI digital textbooks in mathematics, personalized learning and prior research on data for it, and factors for learner analysis in mathematics digital platforms were reviewed. As a result of the study, the researcher summarized the factors for learning analysis as factors for learning readiness, process and performance, achievement, weakness, and propensity analysis as factors for learning duration, problem solving time, concentration, math learning habits, and emotional analysis as factors for confidence, interest, anxiety, learning motivation, value perception, and attitude analysis as factors for learning analysis. In addition, the researcher proposed noon data on the problem, learning progress rate, screen recording data on student activities, event data, eye tracking device, and self-response questionnaires as data collection tools for these factors. Finally, a data collection model was proposed that time-series these factors before, during, and after learning.

Even though measurement is an important strand of elementary mathematics education, there has been lack of research in this field. This study analyzed topics related to length and time in a series of mathematics textbooks aligned to 2007 or 2009 revised mathematics curriculum. The analysis was focused on three aspects: (a) overall instructional components of measurement, (b) instructional components specific to the topics of measurement, and (c) key competencies in mathematics. The results of this study showed that many topics dealing with length and time were represented with relation to real-life contexts or other subjects. The meanings of measurement terms and the necessity of calculation were well explained but other aspects still had room for improvement when it comes to the necessity of measurement units, appropriate choice of units, and use of students' common misconceptions. Another noticeable result was that problem solving, communication, and reasoning among key competencies in mathematics have been emphasized in the mathematics textbooks. Based on these results, this study provides textbook writers with implications on what to further consider in dealing with length and time.
