The purpose of this article is to investigate the effect of visual working memory, the types and contents of graphic annotations on English learning. The participants of the experiments were 5th and 6th graders. The result showed that animation was effective only in the word test for children with large visual working memory, whereas text-only-annotation yielded better performance in the comprehension test in Experiment 1. The effect of relevance of animations was tested in Experiment 2. Context-relevant-animations yielded better comprehension than the animations denoting the typical meaning, whereas the opposite pattern was reported in the word test. The result of the two experiments was interpreted in terms of cognitive load theory and the generative theory of multimedia learning.

In this study, the relationships among high school students' epistemological views on theory and data, science process skills, the perceptions of the preferred laboratory learning environment and attitudes toward laboratory work were investigated. The results indicated that science process skills, all subcategories of the perceptions of the preferred laboratory learning environment (student cohesiveness, open-endedness, integration, rule clarity, and material environment) and attitudes toward laboratory work were significantly correlated with epistemological views on theory and data. The results of multiple regression analysis revealed that science process skills, open-endedness and material environment and attitudes toward laboratory work significantly predicted epistemological views on theory and data.

As the 7th mathematics curriculum reform in Korea was implemented with its goal based on Freudenthal's perspectives on mathematization theory, the research on the effect of mathematization has been become more significant. The purpose of this thesis is not only to find whether this foreign theory would be also applied effectively into our educational practice in Korea, but also to investigate how much important role teachers should play in their teaching students, in order that students accomplish the process of mathematization more effectively. Two case studies were carried out with two groups of middle-school students using qualitative-research method with the research instrument designed by the researcher. It was found that we could get the possibility of being able to apply effectively this theory even to our educational practice since the students engaged in their mathematization using the horizontal mathematization and the vertical mathematization in geometry. Also, it was mentioned that teachers' role was so important in guiding students' processes of mathematization, although mathematization is the teaching-learning theory, stimulating students' activities. Since the Freudenthal's mathematization applied in the thesis is so meaningful in our educational practice, we need more various research about this theory that helps students develope their mathematical thinking.

We developed a Web courseware using multimedia based on STS(Science-Technology-Society) and constructivism on fossil of fourth grade natural science in Primary school, which is recognized to be hard to simulate and watch the phenomena in real life. At present, there are several researches manifesting the effectiveness of the theory with off-line instructional materials. However, there are few results which demonstrate its ability on the Web. The main objective of the paper is to apply the STS theory on a Web courseware and to observe its efficacy. The Web courseware based on the theory allows students to observe and experiment in the Web environment and to have diverse experiences and thoughts through communication via Web. The paper shows that Web courseware based on STS theory can improve its effectiveness in a collaborative learning environment by providing Web facilities such as E-mail, Web search, information sharing, chatting, and so on.

The purpose of the study was to explore experience of self-awareness of nursing students in 'Counseling theory and practice' online class. Participants were 40 of nursing students learning of counseling theory subject in online, and Colaizzi's phenomenological method was used. The results were as follows. There were five theme clusters that 'find hidden my inner side', 'improve my healthy inner self', 'reflection of myself', 'recognize each others' different viewpoints' and 'create an aspiration and an impact'. Therefore, nursing students established self-awareness after learning of 'Counseling theory and practice' online class.

This descriptive study identifies nursing students' methods of studying related to the learning stages, based on a sample of 251 nursing students in a Korean university. The main findings of the study are as follows. The major learning styles of nursing students were accomodation (68.6%), divergen (53.6%), and convergence (38.8%) for the first, second, third, and fourth year group. For all students, the majority (71.3%) showed accomodation or the divergence. The learning styles for grade level were significantly different, (x2=110.021, df=9, p=0.001). The stage of concrete experience was the majority for all of the first year group (51.8%), the second year group (57.1%), and the third year group (61.3%). But, active experimentation (41.9%) was the majority for the fourth year group. Also there were significant differences between the stages of learning by age (x22= 64.391, df=9, p=0.001). The most significant result of the study was the establishment of different modes of learning stages by year, thus supporting the experiential learning theory. The greatest change of style from the first year group to the second year group was reflective observation (7.3%longrightarrow12.9%). That from the second year group to the third year group was the abstractive conceptualization (14.3%longrightarrow21.3%); and that from the third year group to the fourth year group was active experimentation (12.0%longrightarrow41.9%). This reflects the same cycle as indicated by the experimental learning theory of Kolb. According to the study, nursing students' learning stages tended to be more unbalanced as year increases. Therefore this calls for a careful review of the current nursing curriculum.

Many educators say that one of the key theory which is widely accepted teaching-learning process in the 7th mathematics curriculum is constructivism. They believe constructivism is very powerful as a background theory in teaching-learning mathematics and in this point of view, each student can construct knowledge by himself in the inner world. Therefore, the aspect of teaching-learning methods in the 7th mathematics curriculum focused on inquiry learning, self-directed learning, cooperative learning. Through this methods, the 7th mathematics text also composed of ease, interesting and dynamic activity oriented subjects. And constructive teaching-learning methods in mathematics is implemented variously by those whom attracted in constructivism. Thus, the purpose of this study is to build up a model that is required to systematize teaching-learning process in mathematics as a guideline for teachers. Another purpose of this study is to make clear that the presented model is appropriate process for teaching-learning in mathematics.

Rule based machine learning techniques are very important in our real world now. We can list out some important application which we can apply rule based machine learning algorithm such as medical data mining, business transaction mining. The different between rules based machine learning and model based machine learning is that model based machine learning out put some models, which often are very difficult to understand by expert or human. But rule based techniques output are the rule sets which is in IF THEN format. For example IF blood pressure=90 and kidney problem=yes then take this drug. By this way, medical doctor can easy modify and update some usable rule. This is the scenario in medical decision support system. Currently, Rough set is one of the most famous theory which can be used for produce the rule. LEM2 is the algorithm use this theory and can produce the small set of rule on the database. In this paper, we present an improvement of LEM2 algorithm which incorporates the variable precision techniques.

Nowadays in Korea the subject of English education has been rising as one of the essential matters which need to be emphasized, reorganized, and thus refined. From the history of about one century to the current, English education may be compared to an adolescent who should be paid much more attention to grow as an independent adult. Although we recognize that there was much improvement in the past age of English education, a lot of assignments to solve await us. This study aims to suggest a recipe for optimal learning in English classes by linking theory with practice: First, the nation-wide academic associations of English teaching should act more energetically and cooperatively than ever. They need further specialization, dynamic participation, and systematic organization. At the same time the academic journals of their own should be publicized broadly, internationally as well as nationally. Second, there should be close contact and discussion between professors and secondary-school teachers. To achieve better learning in English classes, an effective cycle of equilibrium ought to be maintained by combining theory with practice. For example, language institute in universities/colleges can serve instructional programs such as lectures, colloquiums, and intensive courses for conversation. Third, native speakers of English should be positively utilized. Teachers had better keep close contact with native speakers as frequently as possible if they want to become fluent or at least acceptable speakers in English. Teachers may also use native speakers as aides in their classes.
