운전면허 시험이 존재하는 동안 운전면허 학과시험은 필수적인 시험제도로 존재 할 것이며 향후 상당기간동안 지속적으로 산업화가 될 것으로 전망 된다. 그러나 기존의 서적을 통한 학습은 이미 출제 되었던 문제로 지정된 상황에 대한 대처 방법을 평가하는 것에 지나지 않는다. 또한 운전면허 학원에서 학과시험을 취득 할 경우 과도한 시간과 경비가 소요할 뿐만 아니라 학습효과 면에서도 비효율적인 것으로 평가되고 있다. 때문에 학습자의 능력, 연령 등을 고려한 맞춤형 운전면허 학과시험 시스템의 시급의 도입이 시급하며 이를 편리하게 학습 할 수 있는 E-Learning 멀티미디어 콘텐츠 개발이 필요하다. 이에 본 연구는 이러한 필요성에 따라 학습자의 상황에 맞는 맞춤형 교육이 이루어 질 수 있는 맞춤형 운전면허 학과시험 학습 시스템을 제안하고자 한다. 이를 통해 학습자의 문항반응의 오답분석을 통하여 최적의 평가문제와 학습콘텐츠를 선택하여 학습자에게 제공하는 과정을 반복함으로써 동적 맞춤형 E-Learning 학습방식을 제공하고, 난해한 교통 법규를 쉽고 재미있게 학습할 수 있을 것으로 기대해 본다.

In order to propose effective learning methods to teach basic mathematics course for students of business administration, we conducted the survey on recognition and attitude on mathematics subjects, and analyzed academic achievements of the business mathematics as a basic mathematics course in relation to the results of the survey. First, we investigated learning contents and problems difficult for students to understand in the course, and presented the instructional method and significance of them with examples. These learning contents and problems were collected from the students using the mathematics cafe. Furthermore, we analyzed types of the incorrect answers on the midterm and final examinations in the business mathematics. Although it is difficult to generalize the finding to all of the business administration students due to differences in academic level and educational environment, much work has been put in to present learning method of the business mathematics for students of business administration.

This study is designed to see the characteristics of elementary students' arithmetic error patterns and error rates by going up grades and to draw some implications for effective instruction. For this, 580 elementary students of grade 3-6 are tested with the same subtraction, multiplication and division problems. Their errors are analyzed by the frame of arithmetic error types this study sets. As a result of analysis, it turns out that the children's performance in arithmetic get well as their grades go up and the first learning year of any kind of arithmetic procedures has the largest improvement in arithmetic performance. It is concluded that some arithmetic errors need teachers' caution, but we fortunately find that children's errors are not so seriously systematic and sticky that they can be easily corrected by proper intervention. Finally, several instructional strategies for arithmetic procedures are suggested.

딥러닝이 정답을 찾아가는 연구과정이라면 미술은 정답이나 오답의 단정적 결과보다는 미추(아름다움과 추함)를 포함하는 과정적, 창조적 행위에 가깝다고 할 수 있다. 다시 말하면 미술은 0과 1로만 환원할 수 없는 세계를 기술하여 감동을 주는 유기적 규칙이 내재되어 있고 때로는 과학이 만들어낸 결론을 뒤집는 반상식적 추론을 하기도 한다. 그러므로 딥러닝은 예술적 방식을 통하여 과학의 상식적 추론과의 좋은 거리(Fine distance)를 유지할 필요성이 있는데, 이를 위해서 기존 딥러닝의 이미지 생성과 관련하여 Distance, Classification, Optimization 등의 문제를 미술 표현 기법과 목적이 담겨있는 창작자의 Statement 키워드와의 유사성과 차이점을 비교 분석할 필요가 있다고 생각한다. 시각적 표현과 관련된 딥러닝의 성능은 아직 사람의 표현능력에 못 미치고 있어 본 논문에서는 콜라주 기법에 의한 비디오 생성을 위한 탐색적 실험 분석을 목적으로 GAN을 활용한 콜라주 비디오를 제작하고 그 문제점과 개선점을 제안하고자 한다.

This study intended to draw some suggests for the development of mathematics teachers' expertise through the comparison research of pre-service and in-service teachers' PCK about questioning in elementary mathematics class. For this purpose, questionnaire survey was conducted to some pre-service and in-service teachers about the PCK concerning the way how questioning during mathematics class. This survey revealed the following implications. First, from the perspective of mathematics classroom, it is still more important the practical knowledge about how to teach which is evolutionally developed passing through the experience and currier of teaching than theoretical knowledge itself. Comparing the teachers' PCK about the two related knowledge types of mathematics contents, in case of procedural knowledge related PCK it was more asked of teachers' expertise than the case of conceptual knowledge related PCK. Thirdly, in case of learners' incorrect answer, for the desirable teaching it should be a questioning focused on whether there being or not the systematic among the learners' incorrect answer, and in case of appreciating the learners' understanding about the presently taught contents the questioning should be constructed considering the relevant contents early learned.

Development of Learning system and learning activity based on web in accedence with development of information communication technology are active. From teaming system with web, teaching-teaming data for student's leaning level is not systematic and interactions between students and teachers are insufficiency. Only result of teaming evaluation is showed not supply reason what is correct or not and there is no relationship or linking deeping teaming. In this paper, we tried to improve the interaction between teachers and students by analyzing study system through virtual system on high school's Introduction to computer science. And we designed and implemented the WBI system Using ASP, the system is maximize the effect of study related to further study. It will improve the feedback between the teachers and the students and help the learners enlarge the faculty of comprehension ability.

With the importance of number line in learning fractions, this study investigated how 4th grade students understand fractions and its operations in number line. The questionnaire consisted 22 items which were related to representing fractions, comparing the size of fractions, and operating addition and subtraction of fractions. Both structured number line and sub-structured number line were presented in the items. As results of the study, the overall success rates were not high and even some items showed higher incorrect answer rates than the success rates. Also, the students showed a difficulty in solving non-structured number line tasks. It was also noticeable that students showed several types of incorrect answers, which means that students had incomplete understanding of both fractions and number line. This paper is expected to shed light on elementary students' understanding of fractions and number line and to provide implications of how to deal with number line in teaching and learning fractions in the elementary school.

Most web-based learning is furnishing single side and consistent training resource to learner. Research was gone to apply item analysis method or to introduce web-based learning system using studying pattern. But, we need complicated algorithm or parameter setting etc, for apply these method. Therefore, in this research, we design and implement an item selection system in consideration of learner's incorrectness rate and problem frequency selection rate about question of item selection attribute. Also, as that embody business logic about item selection by EJB, efficient system development is available and we improved maintenance and reusability.

본 논문은 음악 리듬의 속도의 변화가 작업자에게 미치는 영향을 평가하기 위하여 음악의 리듬의 속도를 다섯 단계로 변화시키면서 평가하였다. 평가를 위하여 미리 제작된 MIDI 음악을 들려주면서 피험자가 연산작업을 수행하는 동안의 오답 발생률과 연산반응시간과 뇌파 등 5종류의 생리신호를 측정하였다. 측정 데이터를 분석한 결과 자극음의 속도가 증가할수록 작업자의 오답률이 높아지고 연산 반응 시간이 길어져 작업능률이 저하됨을 관찰할 수가 있었다. 특히 리듬의 특정 속도 ♩=160(160/min)에서 ♩=200(200/min)보다 오답률이 높고 반응시간이 길어지므로 작업에 적합한 리듬의 속도가 존재함을 알 수 있었다.
