The purpose of this study is to provide the basic pedagogical resources for designing the optimum teaching and learning environment in e-Learning through the survey study on learning behavioral styles (LBS) of the gifted students and ordinary students who have experienced e-Learning. And the major results of the study are as follows: The Major field made a very strong difference to the learning behavioral styles between the gifted students and the ordinary students in e-learning environment. On the basis of the study, the LBS sequence of gifted students is the 'passive learning behavioral style', 'environment-dependent and self-directed learning behavioral style', 'positive and cooperative learning behavioral style', 'environment-independent and self-directed learning behavioral style', and the LBS sequence of ordinary students is the 'passive learning behavioral style', 'positive and cooperative learning behavioral style', 'environment-dependent and self-directed learning behavioral style', 'environment-independent and self-directed learning behavioral style'. Simultaneously, there are some individual difference in the learning behavioral style by gender, grade, and the time of using computer between the gifted students and the ordinary students.

This study is to diversely analyze teachers' Pedagogical Content Knowledge (PCK) regarding to the area of plane figures and discuss the consideration for the materialization of the effective class in learning the area of plane figures by identifying the improvements based on problems indicated in PCK. The subjects of inquiry are what the problems with teachers' PCK regarding to the area of plane figures are and how they can be improved. In which is the first domain of PCK, teachers need to fully understand the concept of the area and the properties and classification of the area and length, recognized the sequence structure as a subject of guidance and improve the direction which naturally connects the flow of measurement by using random units in guidance of the area. In which is the second domain of PCK, teachers need to establish understanding of the concept for the area and understanding of a formula as a subject matter object and improve the activity, discovery and research oriented class for students as a guidance method by escaping from teacher oriented expository class and calculation oriented repetitive learning. They also need to avoid the biased evaluation of using a formula and evenly evaluate whether students understand the concept of the area as a performance evaluation method. In which is the third domain of PCK, teachers need to fully understand the concept of the area rather than explanation oriented correction and fundamentally teach students about errors by suggesting the activity to explore the properties of the area and length. They also need to plan a method to reflect student's affective aspects besides a compliment and encouragement and apply this method to the class. In which is the fourth domain of PCK, teachers need to increase the use of random units by having an independent consciousness about textbooks and supplementing the activity of textbooks and restructure textbooks by suggesting problematic situations in a real life and teaching the sequence structure. Also, class groups will need to be divided into an entire group, individual group, partner group and normal group.

This study develops a training program for vocational high school students. This study implemented the ADDIE teaching-learning model and was conducted in the sequence of analyses, design, development, implementation and evaluation. In the analysis phase, the existing studies related to vocational competency training were analyzed along with an analysis of the current education programs and suitability assessment. Based on the analysis, the education program was designed and contents were determined. The program consisted of 5 chapters and 17 unit hours of instruction. Reigeluth's (1987) theory was used as the framework for organizing educational materials in the development phase. The programs were implemented on students and evaluated by students as well as experts. Students evaluated the program in terms of the degree of motivation for learning, comprehension of learning content, perceptions of lessons in classes as well as the advantages and disadvantages of the program. Experts evaluated the program in terms of program validity. The results indicate the developed program was useful for training students vocational competencies as shop managers. This study contributes to the field of fashion education, by presenting an example of systematic development of an educational program in connection with industry.

The purpose of this study is to investigate the difficulties of teachers and students on the unit about 'measuring weight.' In this research, we have acquired data about teachers through survey, interview, and self-reflection journals, at the same time we have collected information on the students through survey, assessment test, and interview. We have extracted the difficulties from analysis with constant comparison method. In addition, we have analysed the curriculum of science and mathematics to know the leaning sequence. The analysis had been checked up by experts in science education. The result of the study is as follows: The difficulties of teachers are from the lack of teachers' descriptive knowledge, disorder of conceptual hierarchy in the curriculum, poor experimental instruments, and low psychomotor skill of students. The difficulties of students are from common misconceptions, opaque concepts, lack of manipulation skill, insufficiency of mathematical ability, difficulty of application of principles to the real situation, and lack of problem-solving ability. In addition, teachers have recognized that students face more difficulties in experiment class, while students think that they face more difficulties in conceptual understanding class.

Evaluating the level of achievement and providing the knowledge which is appropriate at the evaluated level have great influence in studying of the human beings. This shows the importance of the order of training and the training order should be considered in machine learning. In this research, to assess the influence of the order of training, we propose a method of controlling the order of training samples utilizing the experience of supervisor in the training of MLP. The supervisor finds out the current state of MLP using teaching experience and student evaluation, and then selects the most instructive sample for MLP in that state. We use CRF to represent and utilize the experience of supervisor. While the proposed method is similar to active learning in selecting samples, it is basically different in that selection is not to reduce the number of samples to be used but to assist the learning progress. The result from classification problem shows that the method is usually effective in terms of time taken in training in contrast to random selection.

The underlying purpose of this paper is to interest scholars in 'Trade English'. 'Trade English' has to be recognized as one area of 'International Trade' disciplines and more studies have to be carried out with more attention from the scholars. Although there are many areas to be dealt with in 'Trade English', this paper discusses about the syllabus design of 'Trade English' from an educator's point of view. First of all, this paper reviews some theoretical background researches about needs analysis and syllabus design in 'Trade English' teaching and learning as ESP. With a systematic structure under the decent syllabus, selection and sequence of contents get clear and easier. Secondly, along with the rationals based on theoretical researches, how these theories are being or can be applied to the real classroom are discussed for further studies. A different syllabus would be designed according to needs analysis. In reality, the syllabus for practitioners who are doing their jobs in International Trade areas has to be definitely different from the one for pre-practitioners who are studying in International Trade areas at the tertiary education level. Namely, different learners present different needs and different needs make up the different syllabus. In order to provide these learners with the syllabus which can address their own needs, more researches or studies have to be done in the future. Since 'Trade English' is the discipline where two areas-International Trade and English as a second/foreign language-are mixed, the researches or studies also have to be carried out collaboratively by scholars from both areas.

Numerous methods can be employed to teach students and farmers on soil science and fertilizer. The cartoon is one of the most effective teaching aids both for instructors and students. Instructor becomes a director of the cartoon to organize the framework of story based on the chapter of lecture. Director should adapt the regular sentence on soil science into the short and concise scenario suitable for the visual expression of the cartoon, followed by the selection of the scene for drawing. Next is to cast the instructor for the role of actor or sometimes supporter. After casting, the director starts to draw each cut of the cartoon in sequence. I published the cartoons in weekly serials in the farmer's newspaper for three years. Each cartoon was composed of eighteen cuts and formatted with the introductory, main and conclusive issues. Cartoon started with dialogues between the cast on subject to stimulate the interest by farmers, inserted the tables and graphs for the scientific knowledge and summarized the chapter. Major contents covered in the cartoons were glossary, nutrient uptake, pH, salt accumulation, moisture, pollution, chemical fertilizer, compost and other general aspects of soils. Cartoons had been very popular serial of the newspaper and are archived in the web for reviewing.

The purpose of this study was to elucidate elementary school teachers' pedagogical content knowledge regarding the subject of "weight and pressure in water". 6 elementary teachers in charge of the 6th grade were selected for this study. The 7 hour lessons were observed over $15{\sim}20$ days, and a variety of data including scenarios, questionnaires for teachers, interviews of teachers were analyzed. As a result of this study, teachers who had long career histories thought that the purpose of teaching science was to teach the use of science principles, and teachers who had only taught for a relatively short time thought the purpose was satisfying students' curiosity. Most of the teachers felt that the science content knowledge related to buoyancy was insufficient. They had acquired most of the science content knowledge from teaming experiences in middle and high schools. The pre-service teacher education programs didn't help them to satisfactorily acquire the science content knowledge under analysis here. Most of the teachers taught the science lessons according to the order of sequence as shown in the science textbook. They didn't teach the contents that they thought were needed if they were not already included in the science textbook. Only one teacher who had taken science courses in high school managed the science classes freely according to his own thoughts and opinions. From the results of this research, it could be concluded that most elementary school teachers did not have enough pedagogical content knowledge to teach their students effectively.

First: The common points from "syllabus" period to that of "Course of study" are as follows: 1) with no introduction explained. the "Syllabus" or "Course of study" was made to be completed in accordance with the allotment of time (unit). 2) To teach how to rear animals and grow plants, and to make specimens with collected samples formed a great significant field of learning, which meant giving more emphasis on learning classification, life-centered education and basic field of learning than discipline-centered education. 3) The reason why the field of applied biology was emphasized on was that both periods had ideals in Common to educate persons more necessary and useful to the society than to major the pure academic field. 4) Both periods mainly dealt with problems of diseases, and physical health discussed all over the world in 1950's which accounts for necessity of the society to free from ignorance. Second; "The first curriculum period" and "the second one" are observed as follows: 1) The former took the unit (credit) system for the first time. It tried to lay down the conceptual hierarchy with "Biology I" and "II" divided, while "Biolgy I" is better systematized than "Biology II". 2) Discipline-centered education and structure fo knowledge are put more emphasis on especially in "the 2nd curriculum period". 3) And also in this period are included serious problems such as urgency of pollution, importance of nature conservation, population due to the development of industry. 'Third; With the recent curriculum laid down, experiments and teaching contents of subjects are put in harmony with each other and accordingly the process of Inquiry is laid emphasis on. Fourth; It is necessary to set up conceptual sequence and scope effectively in the curriculum.

This study aims to design and implement individual complete learning system based on IPI(Individually Prescribed Instruction) model. Most of current web based learning systems do not consider individual students' ability and just follow the sequence of instructing contents $\rightarrow$ providing problems $\rightarrow$ presenting the result of evaluating. However, this system focuses on individual ability prior to studying subjects. In individual complete learning system, it is acknowledged that a period and a pace to complete each task will differ from students to students, therefore until they complete the whole unit, they are not allowed to move onto the next unit. After completing each unit, there will be a process of evaluating students' performance. It is necessary to show the correct completion of 80% of the evaluation to move onto next step; for those who are evaluated as inadequate to move on, an individual supplementary instruction will be provided. Therefore, this study intends to supplement the deficit of prior learning and provide feedback dependent on individual's learning ability so that the goal of Individual Whole Complete Learning could be accomplished.
