본 연구의 목적은 초등예비교사의 과학개념 수준에 따라서 수업곤란도, 수업만족도, 수업평가는 어떻게 달라지는가를 알아보는 것이다. 본 연구를 수행하기 위해서 P교육대학교 1학년 117명의 학생들을 대상으로 초등과학 '지구와 우주'영역의 개념수준에 따라서 두 집단으로 나누어서 이들 집단의 수업곤란도, 수업만족도, 수업평가에 대한 사전 사후 점수의 결과를 추출하여 결론을 도출하였다. 본 연구의 결론은 다음과 같다. 첫째, 초등예비교사들의 과학 개념수준이 높은 집단이 낮은 집단에 비해서 수업곤란도가 유의수준 .05에서 통계적으로 유의미하게 나타났다. 이것은 개념수준이 높으면 수업단원을 효과적으로 지도할 수 있다는 사실을 말해준다. 둘째, 초등예비교사들의 과학 개념수준 높은 집단이 낮은 집단에 비해 수업만족도 점수는 상대적으로 높게 나왔지만, 유의수준 .05에서 통계적으로 유의미하게 나타나지 않았다. 이것은 수업의 만족도는 교수자의 능력뿐만 아니라 학습자의 수준이나 학습 환경 등 다른 요인이 더 많이 작용하기 때문이다. 특히, 수업자의 언어구사능력, 상호작용 능력 등이 동시에 작용하기 때문이라고 생각된다. 셋째, 초등예비교사들의 과학 개념수준이 높은 집단이 낮은 집단에 비해서 수업평가 점수가 유의수준 .05에서 통계적으로 유의미하게 높게 나타났다. 이것은 개념수준이 높으면 수업을 효과적으로 지도할 수 있다는 것을 말해준다.

강의평가 결과에 영향을 미치는 특성변수로는 교과목 수준의 다양한 강좌특성 변수들과 수강생 수준의 다양한 인적특성 변수들이 있다. 특정 수강생은 다수의 교과목을 이수하기 때문에 다수의 교과목들은 동일한 수강생 안에 속하게 됨으로써 공유되는 특성이 있게 된다. 즉 강의평가 결과는 교과목 수준의 강좌특성 (1-수준)과 수강생 수준의 인적특성 (2-수준)에 의해 영향을 받는 다층구조 (multilevel)를 가지게 되며, 위계적 자료 특성을 가지는 복수의 분석단위의 구조가 된다. 따라서 전통적인 회귀분석에서와 같이 개별 교과목들이 독립이라는 가정을 할 수 없게 된다. 본 논문에서는 강의평가결과에 영향을 미치는 다층구조의 특성을 가진 변수들의 영향력을 보다 타당하게 분석하기 위한 방법으로 위계선형모형 (HLM; hierarchical linear model)을 이용하였다. 분석결과는 다음과 같다. 먼저 교과목 수준의 특성변수들 중에 강좌규모, 개설학년, 담당교수의 전임여부, 해당 교과목의 총 평균평점, 원어강좌 여부가 통계적으로 유의하게 강의평가 결과에 영향을 미친 것으로 나타났다. 또한 수강생 수준의 인적특성 변수들 중에는 성별, 학과계열, 대입당시 전형방법, 평균평점 등이 유의하게 강의평가 결과에 영향을 미친 것으로 나타났다.

The results of frequency analysis, exploratory factor analysis, independent samples t-test, IPA analysis by using SPSS 20.0 were as follows. First, Iquadrant included education contents of enhance ability to ingenuity, teaching method of provides option, teaching method of encourage participation activity, education contents of the aspect of fun, evaluation of motor function and emotion, education contents of explains key contents easily, and education contents of understanding overall context. II quadrant included education environment of good sport facility, class environment of fair opportunity for activity, class atmosphere of arouses interest, and class atmosphere of autonomous and voluntary. III quadrant included diverse teaching method and instructor's demonstration, class atmosphere of systematic learning, evaluation of fairness, objectivity, and credibility, and an atmosphere that can exercise. IV quadrant included education contents of enable acquisition of knowledge and degree of improvement into consideration, and class atmosphere of trust and respect between instructor and student.

This paper presents a characteristic evaluation of commercial gallium nitride (GaN) transistors having two different gate-lengths of $0.4-{\mu}m$ and $0.25-{\mu}m$ in the design of a class-S power amplifier (PA). Class-S PA is operated by a random pulse-width input signal from band-pass delta-sigma modulation and has to deal with harmonics that consider quantization noise. Although a transistor having a short gate-length has an advantage of efficient operation at higher frequency for harmonics of the pulse signal, several problems can arise, such as the cost and export license of a $0.25-{\mu}m$ transistor. The possibility of using a $0.4-{\mu}m$ transistor on a class-S PA at 955 MHz is evaluated by comparing the frequency characteristics of GaN transistors having two different gate-lengths and extracting the intrinsic parameters as a shape of the simplified switch-based model. In addition, the effectiveness of the switch model is evaluated by currentmode class-D (CMCD) simulation. Finally, device characteristics are compared in terms of current-mode class-S PA. The analyses of the CMCD PA reveal that although the efficiency of $0.4-{\mu}m$ transistor decreases more as the operating frequency increases from 955 MHz to 3,500 MHz due to the efficiency limitation at the higher frequency region, it shows similar power and efficiency of 41.6 dBm and 49%, respectively, at 955 MHz when compared to the $0.25-{\mu}m$ transistor.

As an activity of one working group for the Good Practice program at Kumamoto University, we proposed a questionnaire survey on the degree in which students understand the uppermost points of importance in their classes in addition to the usual type of class questionnaire. Each class lists three uppermost points of importance which are essential for understanding the class content. The degree of understanding is classified into four levels: full, most, insufficient, and not at all understandings. Through the analysis of questionnaire replies, the degree of understanding for bachelor students in the Department of Engineering was discovered to be meaningfully affected by the degree of difficulty, the effectiveness of audiovisual aids, self-study time, and class attendance.

This paper introduces a class model based on a course, Internet English, offered by an English department at a university. The course has dual purposes of developing students I English skills and Internet using skills at the same time. In support of using the Internet for language learning, the advantages of project-based language learning and constructivist learning in relation to CALL are explored. The activities in this course, which are basically project-based under the paradigm of constructivist learning perspective, are explained in detail to show the relationship between second language learning theory and teaching application. The way how the four language skills - speaking, listening, reading, and writing - are integrated in this class is described as well. Finally, judgmental evaluation of the course by the students is noted. The results show that a project-based CALL class could be a promising class model to realize an integrative, constructivist, and authentic learning.

In recent years there has been a rise in the use and interest of the flipped learning as a teaching and learning paradigm. The flipped learning model includes any use of Internet technology to enrich the learning in a classroom, so that a professor can spend more time interacting with students instead of lecturing. In the flipped model, students viewed video lectures online outside of class time. Students then performed two kinds of assignments, a teamwork assignment and an individual work assignment, through the class time. In this paper, we propose a flipped educational model for a college class. This experimental research compares class of college algorithm using the flipped classroom methods and the traditional lecture-homework structure and its effect on student achievement. The result data of mid-term exam and final exam were analyzed and compared with previous year data. The findings of this research show that there was not a significant difference in the scores of student between two lecturing methods. The survey result and lecture evaluation by students show that students are in favor of the flipped learning.

Strict priority scheduling scheme is a good candidate for the implementation of service differentiation in an Internet because of simplicity in implementation and the capability to guarantee the delay requirement of the highest class of traffic. However, it is also blown that strict priority starves the lower-class traffic at the cost of prioritizing the higher-class traffic. The purpose of this work is to propose an analytic method which can estimate the average delay performance of Diffserv service architecture and shows that strict priority scheme does not sacrifice the lower class traffic over a diverse condition of the load. From the numerical experiments for three-class Diffserv network we validate our argument that strict priority scheme may be applied to a service differentiation scheme for the future Internet.

This study designed and developed a class using review games as a way to enhance students' interest, class participation, and class comprehension in engineering theory classes, and explored their educational effectiveness. To this end, a review game strategy based on the Creative Training Technique was established and applied to three engineering theory subjects. The types of review games include Jin-jin-ga, Bingo, Challenge Golden Bell, Finding hidden terms, and Completing initial sentences. As a result of applying this review game strategy to the classes over the past decade, students' satisfaction and lecture evaluation scores significantly increased compared to before application, and it was confirmed that students' interest in and understanding of the class increased significantly. Furthermore, this gamification class strategy can be a way to increase students' participation in theory classes regardless of their major, and can be applied to non-face-to-face online classes.
