In this paper, an inverse approach based on uniform load surface (ULS) is presented for structural damage localization and quantification. The ULS is excellent approximation for deformed configuration of a structure under distributed unit force applied on all degrees of freedom. The ULS make use of natural frequencies and mode shapes of structure and in mathematical point of view is a weighted average of mode shapes. An objective function presented to damage detection is discrepancy between the ULS of monitored structure and numerical model of structure. Solving this objective function to find minimum value yields damage's parameters detection. The teaching-learning based optimization algorithm has been employed to solve inverse problem. The efficiency of present damage detection method is demonstrated through three numerical examples. By comparison between proposed objective function and another objective function which make use of natural frequencies and mode shapes, it is revealed present objective function have faster convergence and is more sensitive to damage. The method has good robustness against measurement noise and could detect damage by using the first few mode shapes. The results indicate that the proposed method is reliable technique to damage detection in structures.

The purpose of this study is to examine the sociolinguistic competence of female marriage-immigrants through analyzing their free colloquial discourse. Because previous studies on female marriage-immigrants have not been performed based on the natural illocutionary data, an accurate diagnosis of their communication method will be necessary for the efficiency of the Korean education aimed at them, and for the development of their communication ability. For this study, the colloquial discourse situation from five female marriage-immigrants from China, the Philippines and Vietnam was recorded. The sociolinguistic characteristics were analyzed centering on the use of designation, respect terms, and regional words. 'Eomma' was used as a designation for their husband's mother, which means that 'intimacy' worked for the designation of their husband's mother. The respect-word classes for others were limited to the 'haeyo' form and the 'hae' one, and the reception for listeners was often discarded. In addition, the influence of regional words was found in the vocabulary and grammar, and the more proficient the Korean language, the more frequent the regional word occurrence. Based on the above result, the teaching method of Korean for the immigrants shall be suggested as follows: the teaching has to focus on respect words positively influencing the relationship with the counterpart.

Teachers' perception on educational attributes of new technologies can be dealt with a critical factor for enhancing educational effectiveness through using new technologies in education. The present study attempts to identify teachers' perceptions on educational attributes of cutting edge technologies established through a government-driven educational agenda, "The rural public school model", To achieve this purpose, e-survey was conducted for analyzing the differences of teachers' perceptions on educational attributes of TPCs, e-Whiteboards, and Fastel according to teachers' working areas, school levels, teaching experiences, and training experiences. Participants were 123 elementary school teachers (male:62, female:61) and 66 middle school teachers (male:37, female:29) who are working in the rural public model schools (Gyeonggi: 29, Chungcheong: 12, Jeolla: 30, Gyeongsang: 88, Gangwon: 22, Jeju: 8). The results are as follows: firstly, there were statistically significant differences according to regions, but no significant difference according to school levels; secondly, significant differences in teacher's perceptions on educational attributes of TPCs and Fastel according to teacher's teaching experiences were not shown; thirdly, differences in teachers' perceptions according to their training experiences were meaningfully significant in terms of three new technologies, Based on research results, the implications and further studies are suggested in order to increase educational effectiveness and efficiency for using the technologies.

It takes elementary school teachers long time to search for instructional materials. They have also difficulties with choosing proper contents among much of the overlapping materials. Thus this study set out to investigate the current utilization of web materials by teachers, analyze the materials in the existing homepage, and identify useful materials for teachers. For those purposes, the investigator developed an evaluation framework to analyze science education materials in the existing homepage and analyzed materials using the framework. The materials had developed in the past failed to reflect the demands of teachers, who were the users, actively. Therefore, we took a survey to analyze their demands and reflected the results to establish a set of criteria to analyze materials. After dividing materials according to utilization and format, the external and internal elements of materials were assessed according to the evaluation items. If they systematically select many teaching and learning materials developed for elementary science and make efforts to vitalize their educational usage by sorting out overlapping materials and developing new needed ones, they will be able to save a huge amount of expenses and maximize the efficiency as educational materials.

Although there was an introduction of the class with in mind learner's individual learning ability as a method improving problems of the class which consists of students with various kinds of levels, it was a burden to both teacher and students because of many realistic problems. In this paper, we investigate the efficiency of peer tutoring teaching method which is the one that students having a superior ability for learning become peer tutors and they teach other peer tutee under the teacher's guidance and supervision. After we apply the class-wide peer tutoring to some sophomore classes, we obtain that this teaching method affects positively the students's learning achievement and learning attitude in mathematics class. In particular, we obtain that the peer tutoring is more effective in three to one group than in one to one group.

This study examines the history and current debates on the standardized testing in the United States, particularly focusing on the role that the Carnegie Foundation for the Advancement of Teaching (CFAT) played in the process. It discusses the particular history of the United States associated with the pragmatic and scientific culture, rise of mass secondary education, and the social efficiency movement as the backdrop of the expansion of standardized testing. The role of the CFAT in this movement is investigated as to the way it contributed to setting standards for American secondary and higher education through promoting standardized tests such as SAT and GRE, and by establishing the ETS, a highly influential testing agency. The underlying educational assumptions and practices in standardized testing are critically examined in light of a more personal or context-bound and social justice-oriented paradigm for educational evaluation.
