The specific objectives of the study were (1) to determine the preferences for three home economics curriculum designs(HECD) categorized by Majorie Brown(Technical HECD, Self Actualization HECD, and Practical Reasoning HECD), (2) to determine the differences between middle school HE teachers and high school HE teachers on each curriculum element, and (3) to determine the relationships between preferences for three HECD by curriculum elements and personal and professional characteristics of HE teachers. For these objectives, the subjects were randomly selected from HE teachers of secondary schools in the areas of Seoul, In-Cho, and Keungi. The 300 data collected by mailed survey were analyzed into frequency, percentage, Chi-square, and contingency coefficient using SAS program. The major findings were as follows: 1) the majority of HE teacher respeondents preferred the Practical Reasoning HECD about the following curriculum elements: Purpose of HE education, knowledge, subject matter, teaching method, society and culture, learner, learning atmosphere, and HE teacher's role. 2) No significant difference emerged when Chi-square was applied to determine difference between the two groups(middle and high school HE teachers) on three HECD according to each curriculum element. 3) The contingency coefficient between preferences of HE education purpose for three curriculum designs and age was 21, years of teaching was 23, between preferences of learning atmosphere of three curriculum designs and location of school was. 17. These mean that the younger and more beginning teachers perferred HE purpose of the Practical Reasoning HECD, and HE teachers working in urban area more preferred learning atmosphere of Practical Reasoning HECD.

The purpose of this study is to suggest the interior architecture design studio through the pedagogical method of educational technology for college students who lack self-directed learning. The pedagogical method has been organized to make a student-centered class based on the operation of existing architectural design studios. This teaching and learning method emphasizes the role of teachers as facilitators to help students lacking in self-directed learning in the design process, the BIM visualization to give students an expression of design project and the critics to give students an experience of working circumstances. The results of this study can be summarized as follows. First, This pedagogical model can improve the self-directed learning of students, accomplish the design process well through teamwork, and provide problem based learning (PBL) to settle obstacles that come up during the project. Second, through this model, students can improve their field design capacity by instructor, design feedback and criticism. Finally, This model can suggest new pedagogical methods for interior architectural design studios and management of student-centered studios.

The purpose of this study is to provide an opportunity for better understanding and application of 2009 revised elementary school mathematics textbooks through survey data and focus group interview on structures of textbooks. First, We collect online survey results which 2333 elementary school teachers participated. Next, We interview focus group(8 teachers) about shapes of textbooks, quantity of learning contents, activities and problems for evaluation in the mathematics lessons. Storytelling is especially issued in the 2009 revised mathematics curriculum. We intensively discuss learning and teaching methods with application of storytelling textbooks; interests of students, role of storytelling textbooks etc. As results of analysis, the positive rate to use the 2009 revised textbooks is relatively high about shapes and activities of textbooks. But there is more considered about storytelling method. Storytelling may be positive on improvement of learning interests and participation of students. In order to develop these advantages, studies in relation of storytelling are more proceeded and teaching materials for teachers are required effectively in order to applicate to the elementary school.

We adopt a spirit of Problem based learning to the class of Multivariable Calculus in a school of scientifically talented students and observed effects of our teaching-learning method in the Spring Semester of 2010. Twelve students who enrolled in this class participated in this research. We have proceeded with classroom experiment for the half of semester after midterm exam so that the students could compare our teaching-learning method with usual traditional one in the subject of multivariable calculus. Especially, we investigated changes in the learning attitude and cognitive development of the students toward definition and theorem of mathematics. Each group of 4 students worked on a sheet of our well-designed structured problems of several steps in each class and presented how they understood the way of constructing new definition and related theorems. Instructor's role in this research was to guide students' activities as questioner so that students could attain the clear meanings of definitions and theorems by themselves. We firstly analyzed students' process of mathematization of definition through observing their discussions and presentations as well as their achievements in the quizzes and final exams. Secondly, we analyzed students' class-diaries collected at the end of each class in addition to pre/post surveys.

The purpose of this study is to investigate the effect of computer pointing game on the visual perception ability of children with severe intellectual disability. Based on a literature review, we developed a computer pointing game to improve visual perception ability, which consisted of three stages; catching a hamburger, catching a hamburger and a soda, and catching various foods. At each stage, different instructional models were applied by difficulty level of the contents. Experiments were performed among four children with severe intellectual disabilities for three weeks. They belonged to H public school in Kyeonggi, Korea. Their visual perceptions were quantitatively measured four times by utilizing the Korean Developmental Test of Visual Perception tool (K-DTVP-2). For qualitative evaluation, an observation assessment diary was written and analyzed. All four children at the fourth test showed better visual perception ability, compared with the ability at the first test. As a result of the analysis of the observation assessment, they were considered successful in their learning and ordinary life related to visual perception. It can be concluded that the computer pointing game may play a role in helping children with severe intellectual disabilities improve their visual perception ability.

The objective of the present study was designed to examine that metacognition education had any promoting effects on the development of students' reasoning ability. Two classes in the 5th grade were asked to participated for the present study. Prior to the metacognition teaching, both the experimental and control group classes were given to the preliminary test in which students' basic ability for mathematical reasoning was graded. Then, the students in the experimental group were given 8hour teaching for the topics on the symmetric properties of geometric figures. The present findings indicate that educational application which motivates metacognition can improve mathematical reasoning ability in elementary students. It is widely accepted that metacognition is an active and conscious mental activity, helps the students perceive voluntarily the study items, and further plays an important role in constructing independent and active thinking processes. Accordingly, the present results implicate that the practical performance of metacognition education into the class indeed contributes to build up or strengthen students' voluntary ways of reasoning.

The purpose of this study was to get an implication on teacher education program, by exploring the difficulties pre-service elementary teachers have with their science lessons. 37 pre-service teachers were requested to write an anecdote about their science lessons during their 4 week practicum. By analyzing these anecdotes, the difficulties were grouped into several categories by the researcher, and then reconfirmed by the pre-service teachers themselves. The result showed that there were far more difficulties with practical work (cases: 48), than with content knowledge teaching (cases: 17). Among practical work related difficulties, the most frequent cases were: 1) when they have unexpected result different from scientific theory (cases: 10), 2) when they teach process skill and usage of lab equipments (cases: 8), and 3) when they do not have enough preparation for practical work (cases: 7). Unlike the result of preceding research on secondary pre-service teachers, there was no affective aspect problems. These difficulties also can be divided into 'problems' and 'dilemmas'. Whereas 'problems' can be settled by removing obstacles, 'dilemmas', a conflict-filled situation, require choices between competing values or aims. The use of scientific language, the decision on the level and amount of knowledge they teach, and disposal of unexpected experiment results caused such dilemmas in science lessons. The research results imply practical work should be more strengthened in the elementary teacher education program. And both teacher educators and pre-service teachers need to understand that practical teaching is a complex enterprise accompanying some 'dilemmas'. The role of science teachers as managers of dilemmas could be considered.

According to the new multi-media appeared as a result of rapid growth of the information and science technique, the school library must be changed to the integration of the teach-study media resource from the existing print media. It means that the school library has to play a role of the study center with a different media from the existing teaching material, teaching instrument, facility and opportunity. The Information education must be conducted in the way of an integrated education course and able to do both information transaction and problem settlement. The education facility to solve this problem is the school library. Therefore, the school library becomes important more and more. It means that the school library is the center of entire study and education material for the teacher and student is focused on it. It is urgent to make the standard of the school library In order to cope with the new education and information environments. And especially it is very important to make a plan about the location and scale of the school library to improve the quality of the children's studying activity. The location of the school library is decided under consideration of the relationship with other room of school house and the proper scale of it is between 2.5units and 7.0units of classroom based on the number of class.

Probability plays a very important role in modern society as an essential tool for solving various kinds of problems from our real life or scientific province. However, most of precedent studies on probability pointed out that many students had difficulties in understanding the nature of it, and that probability teaching method in the classroom is easily led only to calculation system, which is isolated from practical applications. In this paper, I make a close study further onto these themes, by analyzing the 8th grade textbooks through these following questions; how do the textbooks deal with calculation of probability that certain two events occur at the same time? On the practical basis, how do they make use of probability as a problem-solving instrument in both actual life and scientific fields? After these, I try to extract some features and issues of probability teaching method in current Korean textbooks.

In most child-care facilities, homeroom teachers take the responsibilities for safety education, which has been conducted in class hours on a regular basis. It was found that most homeroom teachers are lacking in teacher training opportunities, and the younger they are, the less training experience they get. Teachers with fewer teaching careers had a greater interest in safety education and training courses. In addition, homeroom teachers have been utilizing monthly toddler magazines as a method to acquire knowledges for safety education and prevention of safety accidents. The safety accidents which have most frequently occurred in care-care facilities turned out to be stumble and tear, and infants aged 3 years or younger were found to be easily exposed to the safety accidents mainly due to the frolic between peers during the free-choice activity time. The homeroom teachers recognized only traffic safety education among the range of safety training courses, which varied depending on teaching career such as traffic safety education and indoor/outdoor safety environment training, etc. In addition, it turned out that the safety training methods were limited to the utilization of discussion techniques, role-playing, description and demonstration.
