This study was conducted to examine the effects of Internet ethics education. To do so, I compared the knowledge, affectivity and behavior of students on the copyright infringement between before and after Internet ethics education. The subjects of study were 150 students who had taken Internet ethics course in university. Upon comparing their knowledge and affectivity on the copyright infringement between before and after Internet ethics education, they scored higher after education than before, which was statistically significant. The subjects' behavior on the copyright infringement had a tendency to increase after education, but there were not significantly increased. This result showed that the current Internet ethics education has some limitation in making the students practice what they know. To resolve this problem, it is important to do early-childhood Internet ethics education. And more research on diverse teaching and learning methods in Internet ethics education is needed to produce educative results.

As one of the casting plans to improve the scientific inquiry ability of the students, the aims of this study are to develop and apply a basic inquiry program for the inquiry subject of Seogwipo fossil formation, and analyze the basis inquiry ability of the students to show in the inquiry activity process actually. The results obtained in 5th grade 48 elementary school students of Seogwipo-city are as follows; Students executed observing activity using an appropriate senses such as senses of vision and touch, and showed the tendency which tries to observe the form overall rather than the partial form of the fossil formation. But the ability to utilize appropriately for predicting and inferring with the facts which could depend on observing activity was low. And we found out that the misconceptions influence on inquiry activity. Therefore, to help understanding deeper for the students' basic inquiry element, it is thought that a study of the various educational guidance ways is necessary to this. The teachers also have to study the various ways to induce the scientific conception through the application of proper teaching-learning for correction of misconceptions because misconceptions have an influence on inquiry activity together. If various inquiry programs considering the regional-specific characteristics are developed to cause students' interest, students would come to participate in inquiry activity aggressively a little more.

The purpose of this study wasto analyze the factors that enhance their learning achievement in a fieldtrip environment. For this academic goal, we analyzed a pattern of fieldtrip-related perception and attitudes of 19 science-talented students who participated in the 2007 KESO winter school. As for the perception type, the result of analysis showed that the science-talented students understood a fieldtrip as an experimental inquiry from an inquiry perspective, and that their understanding about a fieldtrip was based on anthropocentrism, positivism and instrumentalism from a science philosophy perspective. Regarding theattitudes type, the result revealed that the purpose of the winter school was mainly to learn knowledge in earth science, and that there was a significant tendency for the participating students to become a future scientist more eagerly than their parents expected. Students' fieldtrip-related academic self-concept was mostly positive while the participants experienced both positive and negative emotions.

It is significant that students understand why they have to learn mathematics, because such understanding has a powerful impact not only on affective but also on cognitive aspects in mathematics education. However, studies on in what ways students perceive the purpose of mathematics education are not sufficient. Given this background, this study examined 6th grade students' conception on the intention of learning mathematics by survey and Interview in order to raise subtle but important issues to improve mathematics education. Elementary students showed that they didn't perceive the multiple purposes of mathematics education. Their conceptions were focused on practicality, academic values and the preparation for the future of mathematics. Lower achievers had a tendency to relatively more negative responses to the purposes of mathematics education. This study underlines the importance of the purpose of studying mathematics on the part of students.

The purpose of this study is to find out the influence of Home Economics learning on the recognition and attitude of middle school boy’s home life and to suggest the basic materials for the development of the Home Economics education through students’opinion of Home Economics. For this purpose, a survey was conducted in Cheong-ju area using questionaire. The subjects were 487 boys who studied Home Economics (HE group)and 480 boys who studied Technique (T group) in middle school. The statistics used for data analysis were t-test and x$^2$-test. The results of this study were as follows： 1. The recognition and attitude to home life on the general characteristics of home life； In urban area, the interests in bealth and the role of the consumers were higher than those of rural areas-on the bases of the standard of life, the middle class students had a higher interest in nutrition and food habits, the students whose father were engaged in special job had a higher interest in health and nutrition. 2. The difference of the recognition and attitude between HE & groups； In the field of food life, HE’s knowledge about the six nutrients and the basic food groups and attitude toward buying food were higher than T’s. In the field of family life and resources, HE and T accepted the importance of family life and the role of home as important, hoped to get psychological relax from home and to take the right sexual education. In the field of clothes life, HE and T had the general tendency to have their clothes in proper manner and to select their clothes for themselves, but HE took a higher interest in clothes mending and the role of clothes. 3. The opinions on Home Economics； HE answered that Home Economics was useful to them (more than 90% of HE) and that 57.1% of HE were interested in Home Economics. The order of interest among three fields were as follows： food life, clothes life, family life and resources. 71.9% of T hoped to take Home Economics course.

Learning graphical representations for statistical data requires understanding of the context related to measurement in statistical investigation since the choice of representation and the features of the selected graph to represent the data are determined by the purpose and context of data collection and the types of the data collected. This study investigated whether middle school students can think critically about measurement and scales integrating contextual knowledge and statistical knowledge. According to our results, the students lacked critical thinking related to measurement process of data and scales of graphical representations. In particular, the students had a tendency not to question upon information provided from data and graphs. They also lacked competence to critique data and graphs and to make a flexible judgement in light of context including statistical purpose.

This study aims to investigate how secondary mathematics teachers use mathematics curriculum materials such as textbooks and teachers' guide in planning lessons and for their learning. 24 in-service mathematics teachers participated in surveys and two among them were interviewed. The findings from the data analysis suggest that: a) the teachers actively engaged in decision-making processes of the transition from written curriculum to intended curriculum; and b) the teachers showed a tendency of consulting to the ideas suggested in the curriculum materials for selecting objectives and contents for lessons and the what to assess, not ideas for selecting teaching methods and how to assess. Also, various factors such as students' achievement, participation, interest in mathematics, family environment, and college entrance were identified to influence the teachers' use of the curriculum materials.

By designing and applying the lesson helping to discover the power laws, we tried to investigate the characteristics on the class. To do this, we designed a discovery lesson on the power laws and applied to 54 8th grade students. As results, we could observe the overproduction of monotonous laws, tendency to vary the type of development and increase error to students without prior learning experience, and various errors. All participants failed to express the generalization of $a^m{\div}a^n$ and some participants expressed an incomplete generalization using variables partially for the base or power. We could also observe an error of limited generality or a representation error which did not use the equal sign or variables. In the survey of students, there were two contradictory positions to appeal to the enjoyment of the creation and to talk about the difficulty of creation. Based on such results, we discussed the pedagogical implications relating to the discovery of power laws.

In this study, the tasks of thermal equilibrium and heat insulation concept were divided into scientific and everyday contexts to analyzed the level of familiarity, feeling of knowing, state curiosity, and state anxiety that students feel in task contexts and their relationship. The subjects of this study were One hundred nine students in sixth grade of elementary schools located in metropolitan cities. The results of this study were as follows. First, there was no difference in the level of feeling of knowing, state curiosity, and state anxiety in the task of scientific and everyday contexts. In the case of familiarity, there was no consistent tendency in the concept of thermal equilibrium and heat insulation. And the group who recognized the task context familiarly had higher feeling of knowing and lower state anxiety than the group who recognized the task context unfamiliarly. Second, familiarity and feeling of knowing showed high positive correlation, state anxiety and familiarity showed negative correlation, and state anxiety and feeling of knowing had also negative correlation. In addition, familiarity had a negative effect on state anxiety, and FOK had a positive effect on state curiosity and a negative effect on state anxiety. There was no significant moderating effect of the task context. Third, in case of state curiosity, the group perceived the knowledge gap was very small had the highest state curiosity, and the group perceived the knowledge gap was very large had the lowest state curiosity. In case of state anxiety, the less the knowledge gap was perceived, the lower the anxiety was triggered. This study broadens our understanding of the learning process and provides implications for effective instruction strategies for students' cognitive and emotional states.

As cyber threats have been increased over the Internet, the invasions of personal information are constantly occurring. A malicious user can access the Web site as a normal user using leaked personal information and does illegal activities. This paper proposes an effective method which authenticates a genuine user with real-time. The method use the user's profile which is a record of user's behavior created by Membership Analysis(MA) and Markov Chain Model(MCM). In addition to, user's profile is augmented by a Time Weight(TW) which reflects the user's tendency. This method can detect a malicious user who camouflage normal user. Even if it is a genuine user, it can be determined as an abnomal user if the user acts beyond the record profile. The result of experiment showed a high accuracy, 96%, for the correct user.
