Problem-centered learning reflects learning strategy based on constructivism. In this learning, students should find the solution in a small group discussion, and share their solutions with classmates in whole class discussion. So students participate in mathematics instruction actively and interact with other students about the strategies. We expect students would change their attitudes on mathematics and mathematical learning in these processes. In this study, we analyzed students' attitudes on mathematics and mathematical learning when they participated the problem-centered learning program. We found the change of students' attitudes to mathematics via problem-centered learning.

It is reported that the constructivistic learning method (CLM) enhances the understanding of the students in the learning process, especially in engineering classes. In CLM-based classes, the students can take the initiative in the learning process, which is called the student-centered model of the learning process. This is different from the traditional learning method based on the teacher-centered model, where a teacher plays the central role in the learning process of students. The authors have applied the method of CLM to one of the Engineering classes, namely production planning and inventory control (PPIC) class for undergraduate students. The PPIC class provides multimedia-based study materials and factory visits as well as regular lecture sections to cover the whole subject of inventory control theory and practice. In the review sessions, students are divided into several groups, and question-and-answer discussions were actively carried out among these groups under the support of the teacher as a facilitator. It was observed that the student engagement in the class was very active compared to the conventional lecture-based classes. As for further support of students understanding on the subject, simulation-based materials are also under study for the class. This paper presents the review of case study of CLM-based PPIC class and discusses the feasibility of simulation-based study materials for further improvement of the class.

본 연구는 우수한 영어 수업을 관찰하고 활용된 학습 자료들을 분석하여 효과적인 수업 개선 자료를 제공하는데 목적이 있다. 학습 자료가 수업에서 어떤 양상으로 활용되는 지를 분석하기 위한 도구로는 학습 자료 활용 분석법을 사용하여 활용양상을 양화하였다. 분석 결과 수업 단계별 자료의 사용 정도는 전개 단계에서 가장 많이 활용되었고 그 다음은 도입, 정리 순이었다. 자료의 사용자 비율은 학생보다 교사가 높았으며 학생 개인이나 그룹별 사용 정도보다 학생 전체를 대상으로 학습 자료를 활용한 횟수가 많았다. 학습자료 활용 주체의 비율이 교사가 학생보다 4배 이상 높다는 것은 학습자 중심의 학습 자료 개발이 더 필요한 것으로 보인다. 또한 언어 자료보다 비언어 자료를, 한국어 자료보다 영어 자료를 많이 활용하였으며 문제를 제시하거나 설명을 할 때 학습 자료를 많이 활용한 것으로 나타났다. 본 연구를 통해 우수한 영어수업에서 활용되는 학습 자료의 특징들을 살펴보고 초등 영어 교사들에게 학습 자료의 적절한 활용 방법을 제공할 수 있을 것으로 본다.

The purpose of this study is to apply the PEOE class model that can enhance students' scientific creative problem-solving ability and self-directed learning ability in the middle school science subject and analyze the effects of it on students' long- and short-term retention, scientific creative problem-solving ability, and self-directed learning characteristics. And the paper has gained the following results: First, according to the result of analysis through the pre-test, post-test, and delay test to examine the effects of PEOE-based class on learners' long- and short-term retention, it is found to be statistically significant in the significant level of .05. In other words, the class using PEOE influences learners' short-term retention significantly, but it is even more effective in transmitting the concept that students acquire into their long-term memory. Second, according to the result of analysis through the pre-test and post-test to examine the effects of PEOE-based class on learners' scientific creative problem-solving ability, it is found to be statistically significant in the significant level of .05 in general. However, 'elaboration' and 'originality', the subfactors of scientific creative problem-solving ability, do not indicate significant effects. Third, according to the result of analysis through the pre-test and post-test to examine the effects of PEOE-based class on learners' self-directed learning characteristics, it is found to be statistically significant in the significant level of .05 as a whole. However, 'openness' and 'future-oriented self-understanding', the subfactors of self-directed learning characteristics, do not exert significant effects. Based on the above study results, it can be concluded that PEOE-based class is more effective for learners' academic achievement in science, scientific creative problem-solving ability, and self-directed learning characteristics than lecture-method instruction regarding the middle school science unit of 'The Properties of Air and Weather Change'.

이 연구는 거꾸로 수업에 기반 한 지구과학수업 모델을 개발하고, 초등 예비 교사의 과학수업에 수업모델을 적용하여 그 효과를 분석하였다. 본 연구에서 개발한 수업모델은 교실수업에서 이루어지는 모든 내용과 정보를 사전에 학생들에게 제공하는 것으로 거꾸로 수업에서의 선행과제를 대체하였다. 교실수업에서 '지식'내용은 교수에 의한 강의식 설명으로 20분 동안 학생들에게 수행되었으며, 그 후 학생들은 지식과 관련된 심화탐구문제를 토론 협력을 통해 모둠별로 해결하였다. 탐구문제 해결 후, 모둠원 중 발표자로 선정된 한 학생이 모든 학생들 앞에서 모둠에서 수행한 결과를 발표하였다. 14차시 수업 중에 나타난 학생들의 학습과정과 사전에 제공된 학습 자료의 포트폴리오는 기말고사를 대처한 한 학기의 과정평가로 교수에 의해 운영되었다. 수업에 참여한 많은 학생들은 본 수업 모델이 수업에 대한 집중력, 그리고 토론기술과 사고능력을 향상시키는데 있어서 매우 긍정적으로 작용한다는 인식을 나타냈다. 결론 적으로 본 수업모델은 지구과학수업에서 적용하는데 매우 유용하다고 볼 수 있다.

Capsule endoscopy is one of the increasingly demanded diagnostic methods among patients in recent years because of its ability to observe small intestine difficulties. It is often conducted for 12 to 14 hours, but significant frames constitute only 10% of whole frames. Thus, it has been designed to automatically acquire significant frames through deep learning. For example, studies to track the position of the capsule (stomach, small intestine, etc.) or to extract lesion-related information (polyps, etc.) have been conducted. However, although grouping or labeling the training images according to similar features can improve the performance of a learning model, various attributes (such as degree of wrinkles, presence of valves, etc.) are not considered in conventional approaches. Therefore, we propose a class-labeling method that can be used to design a learning model by constructing a knowledge model focused on main lesions defined in standard terminologies for capsule endoscopy (minimal standard terminology, capsule endoscopy structured terminology). This method enables the designing of a systematic learning model by labeling detailed classes through differentiation of similar characteristics.

This paper presented a course plan based on the ideas I gained from conducting a lecture on Chinese language for students in the second semester of the Chinese language department at a four-year university. In the paper, we sought to deviate from the traditional grammar-translation teaching style and find ways for students to enjoy learning without difficulty in all areas by using the 'total language approach' such as writing, speaking, listening and reading through reading skills. Therefore, we discussed the educational significance and expression of the 'Chinese Languages' class, and introduced the class stages and methods of progress. In other words, they suggested introduction of text plots, explanation of vocabulary and grammar, presentation of original text, questions about text, arrangement of words, ordering sentences to fit the plot, and understanding the plot while looking at the picture.

The purpose of this research was to determine the effects of the functional lateralization of the brain variables related to the sex, the scientific attitude and the scientific exploration skills. The science instruction is divided in each type of the lecturing class with the experiment class. As for the degree of SMR brainwave activation in each stage are presented while accumulating the brain waves from the right, left and the whole brain waves are analyzed during the science learning activities. It is therefore reasonable to consider the science instruction types and brain lateralization to enhance the science learning effectiveness. Sensorimotor rhythm brainwave as the low Beta is represented well to show the thought process. Category quantification scores and objective scores are calculated to show the visual positioning map for the relationships of the categories by homogeneity analysis.

A prototype selection method chooses a small set of training points from a whole set of class data. As the data size increases, the selected prototypes play a significant role in covering class regions and learning a discriminate rule. This paper discusses the methods for selecting prototypes in a classification framework. We formulate a prototype selection problem into a set covering optimization problem in which the sets are composed with distance metric and predefined classes. The formulation of our problem makes us draw attention only to prototypes per class, not considering the other class points. A training point becomes a prototype by checking the number of neighbors and whether it is preselected. In this setting, we propose a greedy algorithm which chooses the most relevant points for preserving the class dominant regions. The proposed method is simple to implement, does not have parameters to adapt, and achieves better or comparable results on both artificial and real-world problems.
