The current research was to investigate the effects of discussion activities based on Havruta style on elementary school students' social studies communication skills. For this purpose, we examined a comparative study between 5th grade students and other students of partner schools. As research results, first, online classes using video conference equipment and smart devices will enhance the students' interest and participation in class. Second, the Havruta style helps students not only acquire and internalize knowledge by themselves through the course of reciprocal questions and discussions but also improve presentations and participations. Third, it is necessary not only to draft a new lesson plan and to reconstruct the education process for video and online classes but also to develop the classes with a lesson plan after preparations and discussions with colleague teachers; the process of reflection, such as writing a lesson research journal, has a positive effect to improve the quality of cooperative classes. Fourth, using SNS discussion activities to serve as a complementary activity is good, and two teachers can evaluate each of the students' achievement. It is necessary to have a sufficient number of schools where video and online cooperative learning is possible with video equipment provided. To maximize the effect of video and online classes, various studies and teacher trainings are needed. Education office needs to provide a server that enables students in small and large classes to freely engage in cooperative learning.

This paper suggests a class model to improve the English oral proficiency for intermediate low English speaking learners. Utilizing the four English skills (reading, writing, listening and speaking), the class model focuses on the learners' schema and discussion strategies. To enhance the learners' motivation and match their cognitive capacity, 10 discussion topics were prepared by surveying the learners. A pilot experiment was conducted to investigate the teaching effects of the discussion class model with 26 college students majoring in English in Seoul. The participants' oral proficiency was measured both before, and after the instructions by OPIc (Oral Proficiency Interview in computer). As a result of the experiment, the percentage of participants whose oral proficiency levels were lower than intermediate mid decreased from 82% to 47%. In addition, the percentage of participants with higher oral proficiency than intermediate low was increased dramatically from 18% to 53%, which supports the claim that through discussion, the class learners' diverse and creative ideas need to be expressed in a formal and intelligible language. Finally, through the findings of the study, the possibility of a discussion class can be expected, regardless of the learners' low level of oral proficiency.

최근 나온 일련의 인물비평서들이 언어 폭력에 의한 비방으로 전락할 우려가 있다는 지적이 있다. 하지만 건전한 토론문화의 장을 열고 공개적인 비판과 평가의 장을 마련함으로써 성숙한 지식사회를 이루는 계기가 될 것이라는 시각은 설득력 있게 다가온다.

This study aims to analyse the effectiveness of the mathematics teacher's training program: whether the training program is effective to improve mathematics teachers' professional competency of the developing assessment instrument (including items) or not. The teachers who were attendee of the program did pre-test before the program and post-test after the program. They wrote the opinions on the pre-developed items which had many errors in the beginning and discussed their opinions each others in the middle of program. The differences between pre-test and post-test and between opinions in the beginning and in the middle were analysed. The first result of the study is that the teacher's professional competency which is evaluated as self-perceived points is improved with regard to understanding the standardized test, item difficulty and item discrimination. Secondly, the proportion of the opinion with concrete reasons is increased as the program progressed. Thirdly, the effective elements of the program are the discussion in the group, discussion between groups, and feedback from the instructor. But the ineffective element of the program is the insufficient time for practicing.

With the popularity of smart phones for mobile learning on the rise, cyber universities in Korea are trying to build a reliable mobile campus infrastructure. Such advances in smart phone technologies have made it increasingly easy for users to stay connected and this heightened interaction through smart phones has educational potential for collaborative learning. Thus, to fulfill its educational potential and ultimately provide optimal learning environments on the smart phones, this study has developed a discussion-based interface prototype for collaborative learning. The proposed interface design was evaluated through cognitive walkthrough of the expert reviewers and its usability improvements were also offered.

Judgment and decision-making studies have shown that people are easily influenced and biased by information irrelevant to the object of judgment. There is a great deal of research that indicates that bias exists in the legal judgment scene. One of them is a bias induced by defendants' character evidence. This study examined whether cognitive activities such as discussion, counterfactual thinking, and peer assessment could reduce the bias induced by the character evidece. In Experiment 1, 121 college students were asked to give the percentage they believed the defendant to be guilty. There was no cognitive activity for the control group. There were three different cognitive activities for the experimental group: discussion, counterfactual thinking and discussion, and counterfactual thinking and peer assessment. Results showed reduction in bias for all the experimental groups, and there was no difference between them. In Experiment 2, there were 125 participants from general population for the same procedure as in Experiment 1. Results showed reduction in bias only for the counterfactual thinking and discussion group. In general discussion, we speculated the implication of the results and the reason for the difference between the two experiments.

CIWS의 성능 및 유용성에 관한 토론은 안전한 실제시험의 구상이 어려우며, 성능입증자료가 부족하다. 유도탄이 안전하게 목표지점을 향해 접근할때 항상 대유도탄 방어체계가 준비되도록 제작자들은 요구받고 있다. 장래의 고객이 미 해군의 지연된 Goalkeeper체계의 평가결과를 아는 것은 가치가 있는 일이다. 그러나 미 해군은 Phalanx 체계에 대한 엑조세(Exocet)와 하-푼(Harpoon) 유도탄의 시험결과를 비밀에 부치고 있다.
