Objectives: The purpose of this study was to examine the influence of cooperative learning on the learning attitude and self-directed learning capability of learners. Methods: The subjects were 50 sophomores enrolled in cooperative learning for 12-week period from March to June, 2014. A self-reported questionnaire was completed by the subjects. The instruments were 16 questions of learning attitude, 32 questions of self-directed learning, academic achievement, and 12 questions of satisfaction with instruction by Likert 5 scale. Cronbach's alpha was 0.84 in the previous study and 0.78 in this study. Self-directed learning was modified by Yoo and Cheong. Cronbach's alpha of self-directed learning was 0.86 in this study. Academic achievement was assessed by before and after the cooperative learning class. Cronbach's alpha was 0.95 in this study. Their learning attitude and self-directed learning capability were evaluated before and after the cooperative learning, and their satisfaction with the instruction and academic achievement were assessed by the written examination. Results: The score of learning attitude increased from 2.89 in the pretest to 3.38 in the posttest. The self-directed learning of the students increased from 2.98 in the pretest to 3.48 in the posttest. The academic achievement of students also increased from 82.0 in the pretest to 85.2 in the posttest. The satisfaction with instruction was 4.24 of Likert 5 scale. There were significant differences in satisfaction with instruction, cooperative learning and academic achievement. Conclusions: It is important to develop the cooperative learning program linked to self-directed learning for the dental hygiene students continuously. This study will provide the basic data and information for the development of new teaching methods for the dental hygiene.

The purpose of this study is to empirical case study for the instructional design of flipped classroom by job-capability advancement of IT business majors. A student of IT business school has learned a lot of management educations for four years. But, they don't recognize a connection between school education and business practice. A subject based on the humanities, and social sciences consisted of mostly the memorization. The undergraduate class lack a practice's curriculum by a creative-oriented lesson rather than memorization-oriented. In particular, An IT business is now recognized as a significance emerging IT investment, the Internet of Things, information security, big data and strategy's ERP. For these reasons, it is important for an instructional design for understanding business practices of the students. Accordingly, Flipped classroom with participatory class be needed increasingly for students' practical sense. We will propose a design method of flipped classroom for inspiring business education. In this, new instructional design overturned traditional teaching method. After the student conducts a prior learn at home, school will accomplish a problem solving through question and answer. This design effected a boredom suppress and creative enforcement of student and an intimacy increase of instructor. In addition, A participatory class and reciprocal peer tutoring will be possible by a spontaneous self-directed learning of student. We were designed course of project type based on big data theory and application to target the fourth-year course. In conclusion, the new instruction provided a help to learning synergy between student and lecturer. During the lessons, the student showed improvement of business sense and enhanced problem solving capability. The lecturer has the intimacy through communication interaction with students.

본 연구의 목적은 초등학교 6학년 학생들의 공간능력과 천체운동개념 및 과학탐구능력의 관계를 알아보고 학생들에게 천체운동개념을 쉽게 이해시키기 위한 교수$\cdot$학습 전략을 찾는데 도움을 주고자 하는데 있다. 연구 결과 첫째, 공간능력과 천체운동개념, 과학탐구능력 성취도에서 남학생이 여학생보다 약간 높게 나타났으나 그 차이는 통계적으로 유의미한 차이를 나타내지 않았다. 둘째, 공간능력과 천체운동개념과의 영향력을 분석한 결과 공간능력은 학생들의 천체운동 개념 이해에 영향력을 갖고 있었다. 천체운동개념에 영향을 미치는 공간능력 하위 요소는 도형유추, 도막세기, 회전등이었다. 셋째, 공간능력은 과학탐구능력의 성취도에 매우 높은 영향력을 갖고 있었으며, 특히 과학탐구능력에 영향을 미치는 공간능력 하위요소는 도막세기가 가장 높았고, 단일요소보다는 여러 요소들이 상호 복합적으로 작용할 때 그 영향력이 더 크게 나타났다.

Etching Process, one of the most important process in semiconductor fabrication, has input control part of which components are pressure, gas flow, RF power and etc., and plasma gas which is complex and not exactly understood is used to etch wafer in etching chamber. So this process has not real-time feedback controller based on input-output relation, then it uses EPD(End Point Detection) signal to determine when to start or when to stop etching. Various type EPD controller control etching process using EPD signal obtained from optical intensity of etching chamber. In development EPD controller we concentrate on compensation of this signal intensity and setting the relative signal magnitude at first of etching. We compensate signal intensity using neural network learning method and set the relative signal magnitude using fuzzy inference method. Potential of this method which improves EPD system capability is proved by experiences.

This study is suggest the test system for BIM(Building Information Modeling) qualification. And this study is the field-based BIM educational program with the acquisition of the qualifying certificates. Since field-based BIM and Curriculum(of University and Junior College) are highly linked to the actual practical affairs, the learning connected to the practical affairs out of the teaching focused on BIM modeling would satisfy students, and it would make the acquisition of the certificates which determinate the capability of the practical affairs. Thus teachers should guide students to get the certificates thoroughly, make them understand the importance of the acquisition of the certificates.

Nowadays, most shop floors using industrial robots have many problems such as constructing robot workcell, generating robot arm moving trajectory, etc.. In the case of programming robot-arms for a specific task, shop operator commonly use the teach pendant to record the target position and determine the moving trajectory. However, such a teaching process may result in an inefficient trajectory in the sense of moving distance and joint angle fluctuation. Moreover, shop operators who have little knowledge about robot programming process need a lot of learning time and cost. The purpose of this paper is to propose a user friendly robot programming method to program robot-arms easily and efficiently for shop operator so that the programming time is reduced and a short and stable trajectory is obtained.

As a consequence of sudden outbreak of COVID-19 pandemic worldwide, educational institutes around the globe are forced to switch from traditional learning systems to e-learning systems. This has led to a variety of technology-driven pedagogies in e-teaching as well as e-learning. In order to take the best advantage, an appropriate understanding of the cognitive capability is of prime importance. This paper presents an intelligent cognitive maturity recognition system for confidence-based e-learning. We gather the data from actual test environment by involving a number of students and academicians to act as experts. Then a Genetic Programming based simulation and modeling is applied to generate a generalized classifier in the form of a mathematical expression. The simulation is derived towards an optimal space by carefully designed fitness function and assigning a range to each of the class labels. Experimental results validate that the proposed method yields comparative and superior results which makes it feasible to be used in real world scenarios.
