본 연구는 260명의 중학생을 대상으로 과학 성취도와 동기적 학습 환경, 성취 목적, 학습 전략 사이의 영향을 경로분석을 통해 조사하였다. 분석 결과, 심층적 학습 전략만이 과학 성취도에 직접적인 영향을 미치는 것으로 나타났다. 과학 교사에 의한 학습 장려와 동료 학생들의 자기 발전 추구는 과제 지향 목적에 영향을 미치고, 이는 심층적 학습 전략을 거쳐 과학 성취도에 긍정적 영향을 미쳤다. 동료 학생들의 자기발전 추구와 상대적 비교 추구는 심층적 학습 전략을 경유하여 과학 성취도에 영향을 주기도 하였다. 또한 동료 학생에 의한 상대적 비교 추구는 수행 지향 목적에 영향을 주고 이는 심층적 학습 전략을 거쳐 과학 성취도에 영향을 주었다. 이는 과학 성취도가 학습 전략과는 직접적 경로를 가지고 있으며, 동기적 학습 환경이나 성취 목적과는 간접적 경로를 가지고 있음을 보여준다. 본 연구 결과는 인지적 요인뿐만 아니라 동기적 요인에도 관심을 기울이는 것이 과학 성취도를 향상시키는 데에 효과적이라는 점을 시사한다.

The purpose of this study was to examine the role of cognitive conflict in the conceptual change process. Ninety-seven high school students in Korea participated in this study. Before instruction, we conducted pretests to measure learning motivation and learning strategies. During instruction, we tested the students' preconceptions about Newton's 3rd Law and presented demonstrations. After this, we tested the students' cognitive conflict levels and provided students learning sessions in which we explained the results of the demonstrations. After these learning sessions, we tested the students' state learning motivation and state learning strategy. Posttests and delayed posttests were conducted with individual interviews. The result shows that cognitive conflict has direct/indirect effects on the conceptual change process. However, the effects of cognitive conflict are mediated by other variables in class, such as state learning motivation and state learning strategy. In addition, we found that there was an optimal level of cognitive conflict in the conceptual change process. We discuss the complex role of cognitive conflict in conceptual change, and the educational implications of these findings.

Purpose: This study was performed to explore the effect of the delivery format on teaching presence, learning presence, and learning outcomes in distance learning of nursing students. Methods: A descriptive survey was conducted to understand teaching presence, learning presence, and learning outcomes depending on the delivery format of distance learning. Quota sampling methodology was used to recruit 295 nursing students from all over the country, and data collection was done from July 27 to September 10, 2020. The first delivery format for distance learning was synchronous learning in which communication between the instructor and students occurred simultaneously. The second delivery format was asynchronous learning in which prerecorded videos were provided and communication did not occur simultaneously. Results: In synchronous learning, teaching presence (especially direct facilitation) and learning presence (especially emotional expression) had a statistical significance that was higher than in asynchronous learning. However, in learning outcomes, there was no statistically significant difference. There were significant positive correlations between teaching presence, learning presence, and learning outcomes, and there were significant positive correlations. Conclusion: It can be suggested that learning outcomes can be improved if presence is improved in the distance learning environment based on the results of this study. It is necessary to add contact with nursing students and instructors to improve teaching presence in the asynchronous learning, and it is necessary to help students express their emotions to improve learning presence.

The purpose of this study is to examine the structural relationship among factors affecting learning engagement, satisfaction, continuance intention in China-MOOC. For this study, data were collected from 334 students who were taking MOOC classes. and structural equation model ling analyses were employed to examine the causal relationships among variables. From the results of this study, First, self-regulated learning and interaction significantly affected learning engagement. Second, interaction had direct effects on satisfaction. Third, satisfaction significantly affect continuance intention. Furthermore, satisfaction mediated relationships between interaction and continuance intention. These results imply that self-regulated learning, interaction, learning engagement should be considered for designing and implementing China-MOOC learning. Further implication are discussed in the study.

Nowadays environmental education is getting important. So, it is necessary to teach for students to realize the protection environment. Self-direct homepage was developed for 'Ecology & environment' environmental education. This homepage was made for sharing searched data and can be interactive each other on the internet. Therefore, in this study, environmental teaming was planned and practiced for high school 'Ecology & environment' class by e-PBL. Self-directed teaming, collaborative teaming and performance assessment are emphasized in the 7th educational curriculum. The PBL is efficient learning model for them. This study designed for a teaching and teaming method and strategies using PBL based upon the theories and practices. This study will also develop an e-learning. As a result, it is indicated that the teaching and learning method using PBL has the positive effects on learning that the development of self-directed learning and collaboration teaming Is observed by reflect journal and presentation of students. e-PBL is a teaming model for learning-centered that adapted many school and subject. Therefore e-PBL makes full use of be 'Ecology & environment' class and environmental education.

The purpose of this study was to evaluate a group activity, reciprocal peer tutoring (RPT), in order to investigate advantages and challenges of RPT in promoting cooperative and collaborative learning environment for EFL University reading instruction. The participants in this study were 89 students taking an English reading course at a Korean university. RPT is a learning strategy whereby learners help each other and learn by teaching. This program was supported by a Vygotskyan perspective which assumes that learners gain mastery and develop cognitive skills through social interaction with more proficient others and their environment. This study relied particularly on participant perceptions through questionnaire survey and Anonymous Online class Report of the course. This study showed various advantages for tutors such as learning through teaching and becoming more autonomous and responsible for their own learning. Non-threatening and highly motivating learning atmosphere are parts of benefits for tutees. Other advantages for tutees included improved level of academic self-confidence, and motivation. This study also revealed several drawbacks associated with the problem of inaccuracy in students' production and students' demand for more direct teacher role. (182 words).

In this paper, we propose a reference input odification-type iterative learning control law for a class of discrete-time nonlinear systems and prove the convergence of the output error. We can get the high-precision in case of the trajectroy control when the proposed control law is properly combined with a feedback controller, and we can easily implement the learning control law compared to the control input modification-type learning control law. To show the validity and the convergence perfodrmance of the proposed control law, we perform experimentations on the trajectroy control and rejection of periodic disturbance for a 2-axis SCARA-type direct drive robot.

In this paper, we present an iterative learning control (ILC) framework for tracking problems with predefined data points that are desired points at certain time instants. To design ILC systems for such problems, a new ILC scheme is proposed to produce output curves that pass close to the desired points. Unlike traditional ILC approaches, an algorithm will be developed in which the control signals are generated by solving an optimal ILC problem with respect to the desired sampling points. In another word, it is a direct approach for the multiple points tracking ILC control problem where we do not need to divide the tracking problem into two steps separately as trajectory planning and ILC controller.The strength of the proposed formulation is the methodology to obtain a control signal through learning law only considering the given data points and dynamic system, instead of following the direction of tracking a prior identified trajectory. The key advantage of the proposed approach is to significantly reduce the computational cost. Finally, simulation results will be introduced to confirm the effectiveness of proposed scheme.
