In this study, 'data collection', 'data expression', 'data analysis, and 'optimization and decision-making' were selected as the core AI concepts to be dealt with in the mathematics for AI education. Based on this, the degree of reflection of AI core concepts was investigated and analyzed compared to the mathematical core concepts and content of each area of the elective course. In addition, the appropriateness of the content of was examined with a focus on core concepts and related learning contents. The results provided some suggestions for answering the following four critical questions. First, How to set the learning path for ? Second, is it necessary to discuss the redefinition of the nature of ? Third, is it appropriate to select core concepts and terms for ? Last, is it appropriate to present the relevant learning contents of the content system of ?

This study is to develop the web-based English learning courseware and improve the motivational attributes, with systematic methods called the ARCS model of Keller. There are four categories to the ARCS motivation model : Attention, Relevance, Confidence, Satisfaction. Applying these four components to web-based courseware strategically will enable learners to be taught English conversation more effectively and more systematically. In order to implement this study, the main web pages are made of ASP(Active Server Page). Personal Web Server is used as the web sever and Authorware is employed as a courseware authoring tool.

This study dealt with the measurements of the positive psychological experience of high school students in relation to mathematics learning by using PPE-M. The purpose of this study is to compare the positive psychology of the high school students based on the grade and gender variables. Measured data for the purpose of this study examined the difference between the gifted students and the general students through a t-test. In addition, differences were analyzed by grade and gender variables. And One-way ANOVA was conducted to see the difference according to the course variables. The difference between the two groups was meaningful in PPE-M total score. There was meaningful difference in all of 5 areas and 19 factors except for 4 factors (Insight, Honesty, Full with pride, and Achievement). However, there was no difference according to grade levels. The comparison between the gender in the ordinary students shows meaningful difference in 11 factors, not in 12 (Judgment, Insight, Honesty, Prudence, Modesty & Kindness, Gratitude & Happiness, Flow, Superiority feeling, Achievement, High pleasure, Full with pride, and Self-efficacy). Affiliation makes meaningful difference in 22 factors except for Honesty.

정보통신 분야는 물론, 문화, 교육 등 생활 속 모든 분야에서 유비쿼터스라는 수식어가 따라다니고 있는 것을 많이 볼 수 있다. 관련 전문가들은 2010년경에는 유비쿼터스가 우리 생활에서 대중화가 될 것이며 이에 따른 부가가치 규모도 80조원에 이를 것으로 전망하고 있다. 교육 분야도 아날로그 환경 하에서 주변 환경 변화에 더디게 반응해 왔던 과거와 달리 최근 조금은 걱정스러울 정도로 IT의 신기술에 발 빠르게 적응하면서 e러닝, T러닝, M러닝, U러닝 등의 새로운 신조어들이 생겨나고 있다. 이에 진정 살아 있는 e러닝의 최종 모습이라고 불려지고 있는 유비쿼터스 학습(U러닝)에 대해 살펴보고, U러닝이 성공하기 위해서는 어떠한 요소들이 필요한가에 대해 살펴봤다.

수학교육 개혁에서 강조되고 있는 교실 문화의 변화는 교사가 그 개혁 방향을 이해하고 자신들이 지향하는 가치와 우선 순위를 수업에 어떻게 적용하느냐에 달려 있다고 볼 수 있다. 이와 관련하여, 본 논문에서는 문헌을 통하여 교수 방법에 영향을 미치는 교사 변인 (교사의 학습 및 교수 경험, 지식, 신념, 개별인성특징) 및 사회문화적 변인 (문화적 ${\cdot}$ 교육적 규준, 교육과정 개발과 운영, 교사교육, 전문적 모델과 교사공동체)을 찾아내고 이를 기초로 하여 수학 교사의 교수 방법에 영향을 미치는 요소를 질적으로 분석하기 위한 구체적인 개발면담 질문을 제시한다.

데이터마이닝의 사전 단계에서 데이터의 차원(Dimensionality)을 줄이기 위한 단계로서 많은 요소선택(Feature Selection) 방법들이 개발되었다. 이 방법은 결과를 예측하거나 데이터를 설명하고자 할 때 어떤 요소들이 관련이 있는지를 결정하는 과정을 포함한다. 또한 이 방법은 데이터의 크기에 대한 확장성 (Scalability)를 향상시키며 학습 모델을 더욱 이해하기 쉽도록 줄 수 있다. 이 논문에서는 NP(Nested Partition) 방법을 사용한 최적화 기반의 새로운 요소선택 방법을 NP 구조의 기본적인 이론 근거와 함께 제안한다. 또 한 편으로 많은 요소선택 방법들이 다중 형태의 데이터를 처리하는데 한계를 가지고 있는데, NP 기반의 요소선택 방법에 다중 형태의 데이터를 처리할 수 있도록 하는 요소 성능 평가도구(Evaluators)를 도입하여 이를 극복하고자 한다. 또한 어떤 평가도구가 특정 데이터 형태에서 더욱 좋은 결과를 보이는지를 실험 결과와 함께 제시하였다.

Since the 7th National Curriculum was established, ICT has emerged as an indispensable tool for teaching a variety of subjects in K-12 education systems. This paper develops the model for explaining the factors affecting students' satisfaction level in using web contents for science class. Based on data collected from a questionnaire survey from the students who evaluated the web sites providing the information related to the science subject, the structural equation model is presented. From this model, a following conclusion is provided : credibility and understandability/motivation are the most important factors affecting the level of satisfaction, but the presentation method, the screen design as well as contents itself has indirect impact on user satisfaction through understandability/motivation. Other interesting results are also provided. This result might provide the useful guidelines for designing the web-contents for science class in high school.

The purpose of this study was to examine the relationship between the attachment of college students to parents and peers as intimate or major attachment objects and their self-regulated learning ability. To accomplish this, we conducted a survey with the parents-peer attachment scale and self-regulated learning scale. As a result, it was found that the relationship between their self-regulated learning ability and parents-peer attachment was significant, while the explicit goal-oriented variable as an essential factor in the regulation of their motivation was excluded. In addition, it was found that the effect of peer and mother attachment on their self-regulated learning ability was relatively high. On the other hand, two variables, viz. the test anxiety in motivation regulation and timing and studying regulation in behavior regulation, were heavily influenced by father attachment. These results could be interpreted in two ways. First, there could be a lower relationship between positive relations and comparative advantages and, second, these two items could be closely related to the negative factors in the relationship between father and child.

Corona, which first broke out in 2020, has caused many changes in many parts of society. Education was not an exception to this change. Teachers had to prepare online classes and students were asked to participate in it without sufficient preparation. Regarding online learning, many studies, in the field of developing teaching module and material or observing the satisfaction of online class, were conducted but there was no study based on how online class is happening in school. Therefore, this study was to investigate the current situation and satisfaction of online class for high school students and explored the relationship between sub-elements of mathematics learning and the level of satisfaction of online learning. As a result, mathematics online class was generally conducted in the form of real-time interactive classes and students felt a little satisfied with it. However, some conflicting opinions were expressed on the continuation of mathematics online learning. In addition, the study found that the higher level of satisfaction students have with online class, the difference appears in the sub-elements of learning mathematics such as values of mathematics, and motivation to learn, willingness to learn mathematics, learning strategies according to the safisfactory level of online class.
