Due to the rapid development of computer technology, online learning using ICT technology is already quickly settling in our lives. Music education was conducted mainly in an offline-based environment, but research is being conducted to switch to online because there is no time and space constraint of online education and interactive education led by learners is possible. In this study, we propose design and implement an adaptive learning system to enable adaptive learning online among music education. This system has the following advantages. First, by providing an LMS-based platform, one can solve the social education problem corresponding to economic and geographical factors. Second, both objective learning feedback provided automatically by the online adaptive harmony learning system and teaching feedback. Third, learners can be provided with recommended answers to given harmony exercises. The adaptive online learning system of harmony will lead professors and learners to effectively teach and study.

The purpose of the present study is to investigate the effects of mathematical communication-centered teaching using peer feedbacks on students' mathematics achievement and mathematical dispositions toward mathematics, and then this study examined the characteristics of feedbacks used by students. To do this study, two sixth grade classes selected from an elementary school in Seoul participated in the current study; one class for a treatment group applying mathematical communication-centered teaching using peer feedback, and the other for a comparison group applying traditional teaching using teacher-centered communication. The results of this study showed the fact that a treatment group of mathematical communication-centered teaching applying peer feedback scored statistically higher than a comparison group applying teacher-centered communication with respect to both students' mathematical achievement and disposition. Especially, this communication-centered teaching program focused on peer feedback was more effective to middle or lower level students than higher level students. In addition, mathematical communication-centered teaching applying peer feedbacks helps students reflect their own thinking process about problem solving, and students experienced the improvement of their confidence about mathematics from opportunities to provide peers with feedbacks. Finally, the present study suggests the important role of communication in mathematics learning, particularly student-to-student feedbacks rather than teacher-to-students feedbacks. That is to say, students need to have many opportunities to represent their own mathematical thinking processes using mathematical language.

The purpose of this study was to examine the effects of formative assessment with detailed feedback on students' science achievement, attitude, and interactions between the teacher and the students. For the study, 133 seventh graders were selected from a girl's middle school in Seoul, and assigned to the experimental and the control groups. The duration of the treatment was over a period of nine weeks. In the experimental group, detailed feedbacks on the solution, teacher's comments on the results, and relevant references were provided after each formative assessment. However, only the answers were presented in the control group. Prior to instructions, a achievement and a attitude tests were administered. After the instructions, follow-up tests which were similar to the pretests were also administered. The results showed significant difference between the two groups in science achievement. It was found that the usage of formative assessments with detailed and supportive feedbacks was more effective in stimulating students' interest, raising their confidence in the subject, increasing their participation, as well as reducing their anxiety. The results also strongly indicated that detailed feedbacks were more effective in improving the interactions of the teacher and the students. The results strongly suggest that formative assessment utilizing detailed and supportive feedback is a necessary component of effective science teaching and learning.

현재 과학과 수행평가는 교사평가가 주를 이루고 있기 때문에 평가 결과의 피드백이 신속하게 이루어지지 못하고, 동료평가가 거의 이루어지지 않는다는 문제점이 있다. 따라서 본 연구에서는 웹의 장점을 이용하여 인터넷 상의 다양한 자료를 보고서 작성에 이용할 수 있고 동료평가와 교사평가를 동시에 시행할 수 있는 웹 기반 과학 보고서 수행 평가 시스템을 설계하였다. 이 시스템의 흐름은 교사의 평가 과제 제출을 시작으로 학생들이 각자 다양한 정보를 수집하여 보고서를 작성하며 작성된 보고서를 동료 및 교사가 일정한 평가 기준에 의거하여 평가한 후, 학습자에게 평가 결과를 피드백하는 것으로 설계되었다. 이러한 시스템을 통해 교사의 업무 부담 경감은 물론, 학습자의 학습 의욕과 성취도 향상을 기대할 수 있다.

Thanks to the spacial and timely flexibility of laboratory's environment, the distance learning based real time PLC education system has been brought into relief as a next generation laboratory alternative. The developed system was installed using a relatively cheap PLC and PC camera. Providing image feedback through the PC camera, the system provides the student's interests of the lab as well as an opportunity to monitor the lab's activities and results.

웹 기반 교육 시스템에서 문제 집합 구성은 주로 고정 출제 방식, 무작위 출제 방식, 난이도에 따른 출제 방식으로 이루어진다. 문제 집합의 구성 시 문제 은행에서 문제 난이도에 대한 객관성을 유지하는 것이 무엇보다 중요하다. 따라서 본 논문에서는 난이도를 재조정하는데 학습자들의 문제 풀이 결과를 반영하는 새로운 난이도 재조정 알고리즘을 제시한다. 본 논문에서 제안하는 학습자 피드백 기반 문제 수준 조절 방법은 개인 시험 결과, 그룹 시험 결과 그리고 개인의 특정 섹션 시험 결과를 함께 고려하여 난이도를 조절한다. 기존 알고리즘과 비교 분석한 결과 문제 난이도의 변화율 측면에서 보다 현실적인 문제 난이도 변화를 확인할 수 있었다.

The purpose of this study was to identify the relationship of instructional design, perceived learning transfer, and satisfaction. The data were collected using questionnaire from the sample of 239 nursing students. The level of learning transfer was explained by introduction with learning context & providing guidance and initial attention. The level of learning transfer was explained by learning object with motivation, learning goal alignment, accessibility and feedback & adaptation. The level of program satisfaction was explained by introduction with learning context & providing guidance and initial attention. The level of program satisfaction was explained by learning object with motivation, presentation design, interaction availability, feedback & adaptation, learning goal alignment and contents quality. The findings serve as basic data to design e-Learning program to improve learning transfer and satisfaction.

This study explored effective teaching-learning activities under the hybrid teaching model combining flipped learning, direct instruction, cooperative learning and distance learning. Subjects were 99 college students enrolled in 2 teacher preparation courses. Students evaluated effectiveness of 22 teaching-learning activities according to Likert scale at the end of the semester. As a result, all 22 teaching learning activities were considered effective more or less. They facilitated motivation, comprehension, participation, thinking, and led to mastery of the task. ② Activities scored low were 'questioning and answering at the beginning of online class', 'open book test'. ③ Hybrid teaching model was favored over traditional instruction. Open ended responses were consistent with the ones in the questionnaire. This research supports the notion that key teaching models to be combined for successful flipped learning in college setting are direct instruction and cooperative learning. Furthermore, effective and ineffective teaching strategies for flipped learning were found.

Touch screen phone which is expected to play a big part of the mobile market for the next few years, has many merits but demerits of inaccurate feedback. It offers audio and tactile feedback to strengthen the weak point. This study aims to see if audio feedback and vibration feedback react upon each other under realistic conditions. We had a qualitative research in perception after using touch screen phone feedback. The result showed that with any feedback users were satisfied more than without any feedback and there was diversity in response. We ran the study again to see the performance level and the projective workload between the kind of feedback and interrupting feedback environment Performance rates were faster with audio feedback and according to the projective workload assessment users felt that task was easier and less annoying with audio-vibration feedback. The results suggest that audio feedback could be more effective than vibration feedback. A future study will figure out the relationship between the factors of qualitative-controlled feedback and learning time and the performance, and the main cause to make people prefer one feedback over another in a realistic world.
