The purpose of this study was to explore and to suggest the effective teaching methods for university students to improve their speaking abilities through peer assessment-feedback and self assessment-feedback based presentation and debate class. The objects and content of the study were the students who took a class "Reading and Communication" of H university, and here examine closely the speaking activities and their effects during the integrated activities of 'reading, speaking and writing'. In speaking education peer and self assessment feedback is to form an emotional consensus among the students and encourage active participation, and enable self-discovery and communication learning to students. As a result of the study, it was found that the variety speaking practice had a very positive effect on the attitude of speaking and the psychological aspect, and it was confirmed that the evaluation and feedback activities had a meaningful learning effect on the students. Effective speech education and guidance measures should be continuously studied and developed.

Generative Adversarial Networks (GANs) are typically described as a two-player game between a generator and a discriminator, where the generator aims to produce realistic data, and the discriminator tries to distinguish between real and generated data. However, this setup often leads to mode collapse, where the generator produces limited variations in the data, failing to capture the full range of the target data distribution. This paper proposes a new training system to mitigate the mode collapse problem. Specifically, it extends the traditional two-player game of GANs into a multi-player game and introduces a peer-evaluation method to effectively train multiple GANs. In the peer-evaluation process, the generated samples from each GANs are evaluated by the other players. This provides external feedback, serving as an additional standard that helps GANs recognize mode failure. This cooperative yet competitive training method encourages the generators to explore and capture a broader range of the data distribution, mitigating mode collapse problem. This paper explains the detailed algorithm for peer-evaluation based multi-GANs training and validates the performance through experiments.

Current performance evaluation of the natural science section mainly focuses on teacher evaluation, which causes slow feedback on the evaluation result and little evaluation on colleagues due to limits of time and space. In addition, report performance evaluation, which is a main target of the evaluation in the natural science section, is conducted mostly based on records of experiments and observation without any systematic forms. Such performance evaluation cannot meet expectation on the evaluation for a self-adjustment through instant feedback on the evaluation result and improvement of motivation through sharing common performance standard. Therefore, the study here completes an experiment/research report through information sharing and discussion among colleague learners based on the web and uses it for colleague or teacher evaluation. In addition, it is intended to recognize needs of learners and develop a performance evaluation system that can provide learners with appropriate feedback through the result.

Peer evaluation is an evaluation centered on the student, through which interaction among students becomes active. The peer evaluation has a greater influence on students than a unilateral directions from the teacher has. This study aims to develop performance assessment models and tasks in which students participate using the remote responder in 4th grade social studies classrooms in the elementary school. It also aims to apply the developed models and tasks to class and to find out how they affect students' academic achievement and attitude. The student participation performance assessment using the remote responder appeared to bring a positive influence on social studies academic achievement and showed statistically significant results. The survey on the students' interests in using the remote responder and its effects conducted after the performance assessment showed positive results.

The purpose of this study was to investigate the effect of a peer evaluation method on the core fundamental nursing skills competency, learning attitude, critical thinking and self-leadership of graduating nursing students. A survey using a questionnaire was administered to 326 nursing students. The data was analyzed using SAS(ver. 9.8) and AMOS(ver.20.0) The results of peer evaluation showed that the fundamental nursing skills competency was 3.77(${\pm}.62$), the learning attitude was 3.17(${\pm}.47$), critical thinking was 3.44(${\pm}.41$) and self-leadership was 3.60(${\pm}.49$). Core fundamental nursing skills competency showed statistical differences based on gender, major satisfaction, practice satisfaction, pre-learning and satisfaction with the peer evaluation. Core fundamental nursing skills competency was positively correlated with learning attitude(r=.295, p<.001), critical thinking was positively correlated with core fundamental nursing skills competency(r=.384, p<.001) and learning attitude(r=.623, p<.001), and finally, self-leadership was positively correlated with core fundamental nursing skills competency(r=.353, p<.001), learning attitude(r=.529, p<.001) and critical thinking(r=.690, p<.001). The factors affecting fundamental nursing skills competency were critical thinking and self-leadership. Core fundamental practical education programs to improve learning attitude, critical thinking and self-leadership need to be developed to increase core fundamental nursing skills.

The purpose of this research was to investigate how the peer review activity of lab report in the problem-solving experiment effected on the description ability and the quality improvement. The students who were taking the general chemistry experiment course were the subjects for this study. They finished lab reports and received peer review from their peers more than two times. The students who got feedback answered on peer review, revised their reports, and subsequently, completed final reports. The result showed that peer review affected the qualitative improvement of the lab report, specially in the process of 'designing experiment' and 'drawing conclusion and evaluation'. Students could organize their thoughts through writing lab reports. During this process, peer review activities provided the opportunity of self-examination and the way for viewing as objective standpoint. Moreover, the activities established communication fields for exchanging mutual opinions and learning.

The purpose of this study is improving the teachers' self-efficacy for pre-secondary music teachers. The research questions for this study were the improvement for teachers' self-efficacy for pre-secondary music teachers and the pre-secondary music teachers' perception about peer mentoring. In this study performed the interview and analyzed the in self-reflection journal in order to identify the improvement effect of teachers' self-efficacy and the participants' perception change in the peer mentoring. As the results from analyzing the change in participant's perception about peer mentoring the mentors had the opportunity to review previous learning contents and practice experiences while developing their team activity and for the mentees. Mentees said that they were given various help from the mentors' advices and their interactions and communication with mentors. From these results, it could identify that there was positive change in participant's perception about the peer mentoring. Based on these results, this study analyzed that it would need to require some chances for pre-secondary music teachers to be given some educational practice and field experience utilizing various teaching methods in order to improve their self-efficacy and the perception of peer mentoring.

지금까지 대학교육의 질적인 측면을 평가하려는 다양한 지표 개발이 있었다. 교육의 성과를 간접적으로 평가하는 지표들이 대표적인 사례다. 하지만 지표들이 질적인 측면을 제대로 평가하지 못한다는 한계점을 드러내왔다. 이를 볼 때 커리큘럼 평가는 해당 분야의 전문가들을 대상으로 한 동료평가 방식으로 진행하는 것이 타당하며 통계상의 오류를 방지하기 위한 보완이 뒤따라야 할 것이다.

Recently diversity of research field is emphasized all over the world. Nations with advanced programs in research field keep developing new R&D programs for interdisciplinary studies. These new research atmospheres need objective validity in evaluation process. Peer review is recognized as a best evaluation method for national research and development programs. However, peer review system has restrictive boundary because of its subjectivity of the reviewer. Scientometrics has been developed as an alternative system to peer review. But the effectiveness of quantitative indicators which also has qualitative aspect is rarely analyzed in real program evaluation. In this study, we suggest distribution of marks of peer review and newly developed quantitative review through analyzing deviations between two different reviews in real national R&D program evaluation. Moreover, we could have significant correlation between two review systems in the same case study.
