In distributed autonomous robotic systems, each robot must behaves by itself according to the its states and environements, and if necessary, must cooperates with other orbots in order to carray out a given task. Therefore it is essential that each robot has both learning and evolution ability to adapt the dynamic environments. In this paper, the new learning and evolution method based on reinforement learning having delayed reward ability and distributed genectic algorithms is proposed for behavior learning and evolution of collective autonomous mobile robots. Reinforement learning having delayed reward is still useful even though when there is no immediate reward. And by distributed genetic algorithm exchanging the chromosome acquired under different environments by communication each robot can improve its behavior ability. Specially, in order to improve the perfodrmance of evolution, selective crossover using the characteristic of reinforcement learning is adopted in this paper, we verify the effectiveness of the proposed method by applying it to cooperative search problem.

This study examined the effects of free writing in writing class targeted for engineering students on their writing skills. To assess the effects, we have asked 100 engineering students from writing class to write free writing, classifying them as the test group(N=50) and the control group(N=50). We have also compared their learning effect, their writing ability, and learning satisfaction via pre and post intervention surveys. The results showed higher change in learning effect, interest in writing, learning attitude, writing ability, learning satisfaction in the test group compared to the control group. This positive change proves that free writing is a significant teaching method in writing class for engineering and science students.

프로그래밍 학습은 프로그래밍을 통한 문제 해결과정을 경험함으로써 고차원적인 사고력의 향상을 목적으로 하는 경향이 있다. 프로그래밍 학습은 주로 학습자 개인의 사고와 원리를 바탕으로 자기 주도적으로 이루어져 왔다. 그러나 선행 연구들 중, 논리적 사고력과 창의성을 바탕으로 하는 소집단 협동학습이 효과가 있다는 결과가 보고된 바 있다. 이에 본 논문에서는 프로그래밍 학습에서 문제해결과정에 소집단 협동학습을 수행하는 것이 문제 해결력 향상에 미치는 영향을 검증하였다. 이를 위하여 문제해결 5단계를 기본으로 소집단 협동학습을 포함하는 모형을 개발하여 적용하였다. 그 결과 소집단 협동학습은 프로그래밍 학습에서 문제해결력 향상에 효과가 있으며, 인지양식에 대해서는 유의미한 차이가 나타나지 않았다.

The purpose of this study was to develop the learning program using sharing nature that can be utilized in Korean elementary science classes and explore the its effects of science academic achievement, inquiry ability, scientific attitude of students after applying it. Sharing Nature used a playful and inspirational teaching strategy and was named after Flow Learning based on universal principles of how people learn. To examine the effects of Sharing Nature Learning Program this learning materials were applied to elementary science curriculum, and an experimental group and a control group were selected from 4th graders at a elementary school located in Icheon City, Gyeong-gi province. The results of this study found significant difference in the student's enhancement of the science academic achievement, inquiry ability, scientific attitude. In conclusion, Sharing Nature Learning Program is useful to develop the elementary school student's science academic achievement, inquiry ability, scientific attitude and had better be widely applied to science education.

The purpose of this study was to investigate whether elementary children's time-use and self-regulated learning ability was different according to gender and whether children's gender and time-use effects self-regulated learning ability. Participants were 2,122 children who participated in KCYPS longitudinal study from their first grade to third grade. Time-use was reported by children's parents. Children's self-regulated learning is invented by Yang(2000). Components of self-regulated learning scale was achievement value, mastery goal orientation, action control, academic time management. The major findings were as follows. First, children's self-regulated learning was different according to chidren's gender. Girls' achievement value, mastery goal orientation, academic time management scores were higher than the boys'. Second, children's daily time was different according to their gender. Third, children's daily time-use affected their self-regulated leaning, however children's gender didn't.

Background: The purpose of this study is to investigate the effect of the online team project based learning on problem-solving, cooperative self-efficacy, and cooperative self-regulation of college students. Design: Single group pre-post design. Methods: The online team project based learning was conducted for a total of 92 college students for 8 weeks. A survey was conducted on problem-solving ability, cooperative self-efficacy, and cooperative self-regulation. In the online team project-based class, two projects were performed. It consists of video lectures and real-time video conferencing. Through the real-time video conference, the project was carried out based on discussion among learners and feedback was provided. Results: There was a significant difference in the change in problem-solving ability compared to before learning (p<0.05). As a result of the evaluation of cooperative self-efficacy, there was a significant difference (p<0.05). There was a significant differences in cooperative self-regulation compared to before learning (p<0.05). Conclusion: The online team project-based learning are effective in improving learners' problem-solving ability, cooperative self-efficacy, and cooperative self-regulation.

The purpose of this study is to develop online educational contents and verify its effectiveness in order to strengthen the learning capabilities of college students. The theme of mind map online education contents is a mind map series for effective learning arrangement, and has been developed into a total of six contents. Each contents consisted of 20-30 minutes, and the details consisted of the concept, principle, learning case, how to write a mind map, and how to use a digital mind map. The results of the study are as follows. First, it was confirmed that the higher thinking ability of college students who took the mind map online education contents was improved. Second, it was confirmed that the self-directed learning attitude of college students improved after taking the mind map online education contents. Third, the reason why students' higher thinking ability and self-directed learning attitudes improved in this study is that they were developed in consideration of the composition of contents and appropriate video time. Therefore, in order to increase the effectiveness of online educational contents, it is necessary to examine specific cases using concepts from conceptual approaches to specific topics, and to faithfully reflect the procedure in which each learner can actually use the concept.

본 연구는 유전에 관한 학업성취도와 학생들의 학습성향과 논리적 사고력과의 관계를 분석하여 학습자에 대한 이해를 돕고 효과적인 수업 설계를 위한 기초적 자료를 제공하고자 실시되었다. 서울 시내 중학교 3학년 149명의 학생을 대상으로 유전단원에 관한 학업성취도 검사를 실시하였다. 학생들이 학습과제에 대하여 유의미적 또는 암기적 으로 학습하는 경향을 알기 위하여 Biggis(1987)의 학습성향 검사지를 사용하였고, 학생들의 논리적 사고력 수준을 파악하기 위하여 GALT 축소본 검사지를 이용하였다. 본 연구의 결과, 학생들은 감수분열과 유전 법칙에 대한 이해도가 낮았으며 여학생이 남학생보다 유의미적으로 학습하는 경향이 있고 학생들은 대부분 (48.76%) 과도기의 사고력 수준에 머물러 있음을 알았다. 학습성향과 논리적 사고력은 학업성취도와 상관이 있었으며, 학습성향과 논리적 사고력 사이에는 상관이 거의 없었다. 또한, 학습성향은 학업성취도 대하여 11.6%의 예측력을, 논리적 사고력은 24.7%의 예측력을 가지며 학습성향과 논리적 사고력은 모두 정성적 문항에서 보다 정량적 문항에 높은 예측력을 보였다. 학습성향 수준에 따른 학업성취도와 논리적 사고력 수준에 따른 학업성취도는 통계적으로 유의미한 차이가 있었고, 학업성취도에 대한 학습성향 수준과 논리적 사고력 수준의 상호작용 효과는 없었다. 또한, 과도기와 형식적 조작기에서 유의미 학습자는 암기적 학습자보다 높은 학업성취도를 보였으나 구체적 조작기에서는 유의미 학습자와 암기적 학습자의 학업성취도에 차이가 없었다.

The 121 five-year-old Korean subjects of this study were divided in 3 groups based on their experience in learning a foreign language (English). A battery of tests was administered to measure spoken and written language ability and the 3 metalinguistic domains of phonological, semantic, and syntactic awareness. Spoken language ability was positively correlated with semantic and syntactic awareness. The relative importance of each metalinguistic domain varied with level of written language development. Phonological awareness was the only predictor of decoding. Syntactic awareness and phonological awareness were significant variables in sentence comprehension. Metalinguistic ability was a better predictor of written language development than spoken language ability. Foreign language learning experience had an effect on syntactic awareness: low experience was superior to no experience, but high experience was not superior to low experience.
