  • It is important to construct a firm basis for accusing potential violators of academic integrity in order to avoid spurious accusations and false convictions. Educational researchers have developed many statistical methods that can either uncover or confirm cases of cheating on tests. However, most of them rely on simple correlation-based measures, and often fail to account for patterns in responses or answers. In this paper, we propose a new statistical index denoted by a Standardized Signed Entropy Similarity Score to resolve this difficulty. In addition, we apply the proposed method to analyze a real data set and compare the results to other existing methods.

  • This paper provides a review of the historical development story of the NCTM 1989 Standards based on perspective of history of U. S. mathematics education and research in the 1970s and 1980s. In contrast to other nations, the U. S. has always favored local over national control of education. But by 1983, mounting evidence of failures of U. S. education moved the authors of A Nation at Risk to recommend strengthened requirements, rigorous Standards, and higher expectations for all students. In response to A Nation at Risk, the NCTM began to develop the nation's first educational Standards. This paper satisfies the readers who desire to know the entire development story of the first Standards.

  • Background Phenomenography suggests that more variation is associated with wider ways of experiencing phenomena. In the discipline of mathematics, broadening the 'lived space' of mathematics learning might enhance students' ability to solve mathematics problems Aims The aim of the present study is to: 1. enhance secondary school students' capabilities for dealing with mathematical problems; and 2. examine if students' conception of mathematics can thereby be broadened. Sample 410 Secondary 1 students from ten schools participated in the study and the reference group consisted of 275 Secondary 1 students. Methods The students were provided with non-routine problems in their normal mathematics classes for one academic year. Their attitudes toward mathematics, their conceptions of mathematics, and their problem-solving performance were measured both at the beginning and at the end of the year. Results and conclusions Hierarchical regression analyses revealed that the problem-solving performance of students receiving non-routine problems improved more than that of other students, but the effect depended on the level of use of the non-routine problems and the academic standards of the students. Thus, use of non-routine mathematical problems that appropriately fits students' ability levels can induce changes in their lived space of mathematics learning and broaden their conceptions of mathematics and of mathematics learning.

  • In this study, we investigate the effects of the methods of time allocation in lecturing on the mathematical academic achievement of freshmen in institute of technologies. The subjects are 392 freshmen from three universities participated in ABEEK(Accreditation Board for Engineering Education of Korea). They belong to three groups in accordance with the methods of time allocation in lecturing; 75 minutes twice a week(79 students) and 150 minutes continuously once a week(77 students) (university 1 of 156 students), 100 minutes twice a week(56 students) and 200 minutes continuously once a week(60 students) (university 2 of 116 students) and 50 minutes and 100 minutes separately once a week(62 students) and 150 minutes continuously once a week(58 students) (university 3 of 120 students). The results of this paper are summarized as follows: Firstly, the achievement of separate time-allocation groups is higher than that of continuous time-allocation groups. Secondly, the achievement of middle class students and low class students has higher effects when they are taught by using the methods of separate time-allocation in lecturing. Finally, the achievement of groups using 75 minutes twice a week is higher than that of using 50 minutes and 100 minutes separately once a week. In conclusion, this study suggests that the method of separate time allocation in lecturing using 75 minutes twice a week could be an advisable means to help those who achieve middle and low scores in the first college mathematics.

  • This study was inspired by the growing importance of information as a resource for improving the quality of life, the lack of systematic research about the information environment of Koreans in the United States and the lack of understanding of the relationships between individual characteristics and information seeking behavior. During 1990 and 1991, 204 Koreans, 18 years old and more, residing in the City of Los Angeles, were interviewed. Generally the information seeking behavior of Koreans appeared to be similar to that of the socioeconomically advantaged segment of the general public. They are relatively well aware of their information needs. capable of articulating them, and willing to pursue information to meet their needs. Major findings include: (1) the dominance of educational information needs: (2) positive feelings of hope, curiosity. and interest associated with information needs: (3) the tendency to pursue information with the expectation of potential rather than immediate rewards: (4) the expertise of information sources and their ability to provide information directly relevant to a need as criteria for selecting an information source: (5) the generally heavy reliance on informal interpersonal information sources and the high ranking of professionals as the starting point for information seeking and in judgements of usefulness: and (6) the dominant use of Korean ethnic information sources. Statistically significant correlations found at the 0.05 level relate (1) level of education, age, and gender with type of information need, the feelings associated with an information need, motivations to seek information, and the use of information sources, (2) proficiency in English and length of residence in the United States with the extent to which ethnic information sources are used, and (3) pattern of daily use of media with the use of media in seeking information.

  • The purpose of this study is to develop a measurement tool for the quality of information commons. Information commons is a physical, technological, social, and intellectual place where library users can experience various educational, research, and cultural activities. It is recently gaining popularity and several libraries have implemented it to help users share knowledge and interact with each other. It also intends to provide a place for collaboration, learning, and rest. Despite its benefits and usefulness, there is no measurement tool explicitly designed for the quality of information commons. This study used in-depth personal interview, compared prior studies, and conducted a pilot study to elicit library users' perceptions on information commons and factors influencing on the perceived quality of information commons. Groups of initial items were emerged through classifying and clustering key concepts in the data. Then, the validity of the items were verified through a pilot study. The findings of this study will be useful for developing more reliable and valid survey measurement tool.

  • In this paper, we adapted the frame by Lee et al (2013) to investigate to what extent the Korean mathematics textbooks for the 7th graders adapt the principles of Yungbokhap education. The analysis suggests that the textbooks mostly adapt the competence to use language, symbols and texts interactively, and to use knowledge and information interactively. Among the competencies for interacting in heterogeneous groups, the textbooks included the competences to related well to others and to cooperatively work in teams. The competence for acting autonomously was least adapted in the textbooks. The most tasks in the textbooks adapted the monodisciplinary integration and the personal contexts for integration. The results of this research show that Korean mathematics textbooks are limited in implementing the principal dimensions of Yungbokhap education. In the future development of mathematics textbooks, it is necessary to consider how to further reflect the various dimensions of Yungbokhap education to promote students' creativity and autonomy in mathematics class.

  • In today's world where a preference for prestigious brands prevails, it's essential to have creative design conceptions rather than try simple mimicking or following in order to be recognized for creative and objective design works. In that sense, the development of clothes design using construction lines offers a great approach towards the ideas of reinterpreting and creating new designs since it creates new forms by understanding lines as signs of conception and transforming them. That approach allows a designer to improve his or her imagination, creativity and expression in a freer and richer manner, think of many original ideas through diverse changing processes, and develop the skill to visualize the ideas by incorporating geometric forms of abstract lines into clothes. When approaching the conception of clothes design from the standpoint of construction lines, you need to adopt more specific and systematic design methods instead of vague imagination to introduce simple facts or theories to a new design process. That's one of the ways you can approach clothes design easily and enhance your conception skills. The process of clothes design according to the conception of construction lines is composed of the following stages; the preparation stage involves an understanding of the principles and the entire process of clothes design conception based on construction lines; the idea stage requires a designer to make free alterations of the given basic construction lines by moving and replacing the lines and sides in diverse ways; in the creation and expression stage, the designer uses the newly reconstructed construction lines to create clothes design; and in the evaluation stage, the designer makes a presentation of his or her subjective design works and has his or her works assessed and tested in an objective fashion. In today's modern society that demands new and original globalized design, the results of the study will help to invigorate the development of new fashion design in a more systematic and practical manner by suggesting a feasible and gradual educational program for the development of design based on the technique of construction lines.

  • In this study, the impact of the fashion design education on the brain wave and the psychological change of the senior females and its change was intended to analyze. 16 senior females were selected as a subject and the brain wave and the psychology were analyzed before and after the educational program of 4 hours a day for total 3 weeks. Out of the brain wave, the increase of alpha wave represents the mental stability and the comfortable state and its decrease represents the tension and stress. On the contrary, the increase of beta wave represents the tension and the excitation. In the brain wave analysis results, the alpha wave was increased and the beta wave was decreased after the design education program, through which it is deemed that the design education would help to increase the psychological stability and to decrease the tension and the stress in the senior females. In the results of analyzing the psychological test, while the test results for 4 senior females were shown as anxious out of 16 senior females, the BAI score was decreased to 'minor anxiety' after the education and the BAI score was decreased except 2 subjects, through it is deemed that the fashion design education would help to reduce the anxiety in the senior females and it seems that it is coincided with the beta wave analysis results.
