In this study, the effects of STAD cooperative learning strategy on students' achievement, learning motivation, perceptions of learning environment, and perceived classroom goal structure were investigated in terms of students' collectivism level. Two classes (64 students) from an elementary school were respectively assigned to a control group and a treatment group. A individualism-collectivism test, a learning motivation test, a perceptions of learning environment test, and a perceived classroom goal structure test were administered as pretests. The intervention of cooperative learning lasted for 24 class periods. After instruction, an achievement test, the learning motivation test, the perceptions of learning environment test, and the perceived classroom goal structure test were administered. The results indicated that the students of the treatment group significantly outperformed those of the control group in the achievement test. There was a significant treatment-aptitude interaction effect in the scores of the attention subcategory of the learning motivation. In the perceptions of learning environment, the score of the treatment group was significantly higher than the control group in the cohesiveness subcategory, whereas the score of the treatment group was significantly lower than their counterpart in the competitiveness subcategory. It was also found that the score of the treatment group was significantly higher than the control group in the performance subcategory of the perceived classroom goal structure.

Programming education helps learners solve real world problems by applying the principles of computer science. In particular, in the case of object-oriented programming centered around objects or problems that are observed in the real world, learners are able to make the most use of their programming skills in real life. Therefore, in this study, we sought ways to have learners grasp object-oriented concepts in a learner-friendly manner. To this end we conducted an experiment with six students as participants. As a result we could derive two main points. First, the learning tools which can be easily used by learners are required. Second, it is necessary to think thoroughly to learn concepts before implementation of the programming. This study has significance in the sense that it provides a learning method which helps a novice learner to learn the object-oriented programming that he or she feels difficulty to understand.

In-person lectures have structural issues that active communications in the classroom are limited because of the environments where the instructor usually delivers learning contents in a unilateral manner. Therefore, microcontents activities using real-time microblogging were suggested as complementary measures for the lecture in this study. Fourteen students in K University participated in the learning activity for eight weeks using a microblog during instructions. As a result, it was found that participants' positive learning activities increased by producing and collaborating ideas through real-time microblogging. Based on the results, suggestions were made as follows: strategies for the attention to the class, quality management of microcontents, and the development of blended learning design should be more studied further.

Program learning outcome is widely used for assessing and improving program quality. There are various methodologies that can measure program quality and improve program learning outcomes. In this paper, we used formative approach in Capstone design course, since it is the most effective in terms of improving program learning outcomes due to the course's intrinsic nature. To integrate a formative approach into Capstone design course, we develop a feedback structure which is a key element in formative approach and define several sub phases that manage feedback structures and their own evaluation criteria. As a result, we observed a noticeable improvement for students performance in capstone design course.

Contemporary Christian educators emphasize that the student has to become not a passive beneficiaries of knowledge, but an active subject for self-directed learner to pursue a Bible training. In addition, learning environments need to be converted into a learning place in which students can learn the principles of the Word, taste its meaning, and apply them into the scene in their lives. This study is to investigate new possibilities of self-directed volunteer camp, developing it as an alternative program for summer retreat and evaluating its effectiveness. According to qualitative research findings. self-directed volunteer camp provide for the youth students to develop their leadership as well as their faith. Especially, the higher effect of self-directed volunteer camp was found on program satisfaction, promoting cooperation through real problem-solving, and internalizing of the faith. Therefore, self-directed volunteer camp for vacation Bible church programs can be expected as an alternative teaching method for church education in the 21st century.

This study is based on the recognition that the school mathematics education should reinforce the heuristic and constructional aspects related with discoveries of mathematical rules and understanding of mathematical concepts from real world situations as well as the deductive and formal aspects emphasizing on mathematical contents precisely. The 11th grade students of one class from a city high school with average were chosen. They were given time to learn various functions of Excel in regular classes of "Information Society and Computer" subject. They don't have difficulty using cells, mathematical functions and statistical functions in spreadsheet. Experiment was performed for six weeks and there were two hours of classes in a week. Considering the results of this research, teaching materials using spreadsheets play an important role in helping students to experience probabilistic and statistical reasoning and construct mathematical thinking. This implies that teaching materials using spreadsheet provide students with an opportunity to interact with probabilistic and statistical situations by adopting engineering which can encourage students to observe and experience various aspects of real world in authentic situations.

Problem development is important to Problem-Based Learning (PBL) and is key to the creativity and problem-solving skills of successful learners. The purpose of this study is to have PBL classes that effectively materialize problem development stages, and to develop learning using problems suitable for elementary school English Science classes. In this study, the steps for developing the problems are identifying educational content, identifying learners' characteristics, discovering problems, setting up roles and situations, and writing problems. Based on these steps, five PBL problems were developed by selecting a subject suitable for the PBL method of an English Science class, which is one of the English curriculums in elementary schools. Creative thinking, problem-solving skills, presentation skills, confidence, self-directed learning, cooperation, and communication skills are required in the rapidly changing society of the 21st century, rather than teacher-centered instruction, acquiring knowledge for correct answers only, and uniform assessments, which still take place in many English education settings. Therefore, developing problems suitable for PBL learning should be continuously studied.

Path generation methods are required for safe and efficient driving in unmanned autonomous vehicles. There are two kinds of paths: global and local. A global path consists of all the way points including the source and the destination. A local path is the trajectory that a vehicle needs to follow from a way point to the next in the global path. In this paper, we propose a novel method for local path generation through machine learning, with an effective curve function used for initializing the trajectory. First, reinforcement learning is applied to a set of candidate paths to produce the best trajectory with maximal reward. Then the optimal steering angle with respect to the trajectory is determined by training an artificial neural network. Our method outperformed existing approaches and successfully found quality paths in various experimental settings, including the cases with obstacles.

4차 산업혁명으로 기존 일자리가 사라지고 있으며, 보다 창의적인 진로전략이 요구되고 있다. 기존의 진로전략이 구직(求職), 즉 '직업을 찾는다.'는 개념이었다면, 4차 산업혁명 시대의 중요한 진로전략인 창직은 구직의 틀에서 벗어나 개인이 직업을 적극적으로 발굴하고 일자리를 창출하는데 초점을 두고 있다. 즉, 개인이 직업을 '발굴하고', '선택한다.'는 점이 중요하며, 구직이 '남이 나를 고용한다.'는데 의미가 있다면, 창직은 '내가 나를 고용한다.'는 점에서 구직자의 주체적이고 적극적인 의지를 더욱 필요로 하고 있다. 창직교육을 통해 청소년이 자신의 진로를 직접 발굴하고 선택할 수 있는 진로결정 자기효능감의 향상이 자기고용을 이루기 위한 주체적이고 적극적인 의지를 반영하는 창업의지에 미치는 영향을 분석하기 위해 본 연구를 진행하였다. 본 연구의 결과는 다음과 같다. 창직교육 프로그램을 처치한 실험집단은 총 293명으로 검증 시 진로결정 자기효능감, 대인관계기술, 자기주도 학습력, 기업가정신, 기회발견, 기회활용, 사회적 문제해결력, 창의성역량, 창업의지 전 항목에서 통계적으로 유의한 수준에서 평균값의 상승을 보였다. 창직교육 프로그램을 처치하지 않은 통제집단은 총 85명으로 사전/사후의 평균값이 미미한 수준의 차이를 보였다. 실험집단은 통제집단에 비해 자기주도 학습력과 창의성역량이 매우 두드러지게 향상되었고, 진로결정 자기효능감과 창업의지가 두드러지게 향상되었다. 반면, 통제집단은 실험집단과 비교하여 자기주도 학습력과 창의성역량이 미약하게 향상되었고, 진로결정 자기효능감도 미약하게 향상되었으나 오히려 창업의지는 감소하였다. 본 연구로 창직교육을 통한 자기주도 학습력과 창의성역량의 향상이 진로결정 자기효능감과 창업의지에 매개변수가 되어, 진로결정 자기효능감과 창업의지를 향상시켰음을 알 수 있다.
