The purpose of this study was to analyze the types of questions of energy field in the elementary science textbooks and to know the preference types of questions of students by grade. To accomplish this study, the analyzing framework on the types of questions was made and ensured the validity. To know students' preference types of questions, a questionnaire was made and the survey was conducted to the students of D elementary school in B city. The results can be summarized as follows: First, of the questions in the elementary science textbooks, the types of limited question were the most frequent(56%) and the next was the type of relevant question(41.82%). In the type of limited question, the element of propositional type was the most frequent and in the type of relevant question, the element of applicable type was the most frequent. Second, from the result of analyzing students' preference types of questions by grade using questionnaire, we could find as follows. Most of the graders chose retrospective type of question as the easy types of questions. And 3, 4, 6th graders chose justificative type and 5th graders chose applicable type as the difficult ones. Third, as interesting type and want-to-select type, 3th graders students chose propositional type and 4, 5th graders chose retrospective type and 6th graders chose inferring type.

This study examines the introduction of fractions in the third grade mathematics textbooks focusing on stages of units coordination and suggests alternative activities to help students develop their understanding of fractions. As results, the sessions of introduction units in textbooks was well organized to allow students to construct more extensive fraction schemes (i.e., Part-whole fraction scheme → Partitive unit fraction scheme → Partitive fraction scheme). However, most of the activities in textbooks were related to stages 1 and 2 of units coordination. In particular, the operations and partitioning schemes (i.e., equi-partitioning and splitting schemes), which are key to the development of students' fraction knowledge, were not explicitly revealed. Fraction schemes also did not extend to the Iterative fraction scheme, which is central to the construction of improper fractions. Based on these results, this study is expected to provide implications for the introduction of fractions in textbooks focusing on stages of units coordination to teachers and textbook developers.

The purpose of this study was to find a desirable time to ask a question to effectively improve creativity as an engineering viewpoint and apply it to daily schedule as a diverse teaching method in daily schedule of young children's curriculum. Forty five young children among three kindergarten of G Metropolitan City, aged 5, were selected as a subject for this study. Type A of Thinking Creatively with pictures, TTCT was used as an instrument, and the resistant score for the lower level of elements: Fluency, Ingenuity, Originality, Abstractness of Titles, hasty conclusion. The total score of creativity was highest in the 1st-time period ($M=95.52{\pm}12.21$). As a result, it was concluded that desirable story-telling time should be after 10 a.m., the 1st-time period, to improve the highest creativity.

Today, art education needs education of media image production or media in the extended field. The purpose of this study is to develop the basic visual grammar and communication ability. We developed and applied the teaching plan for the interview video production as the fusion lesson. 3 classes were conducted for 30 middle school students. The results obtained through the analysis of the pre & post questions and student works are as follows. First, the students used the shot size and stable composition through the interview video production. As a result, this class was effective for the acquisition of the basic video grammar. Second, students improved their ability to ask and listen, understand and organize through interview. As a result, students were able to apply the basic video grammar through the interview video production lesson, effectively producing the interview image.

The purpose of this study is to improve education program for Informal Science Education Institution by analyzing education program of Natural History Museum, one of informal science education institution. This research subject is Seodaemun Museum of Natural History, located in Seodaemun-Gu, Seoul. It is Public Natural History Museum, which runs more than 60 education programs every year continuously for recent 6 years. Objects of this study are 32 education programs for 3rd to 6th grade of elementary school. The result of study shows that teaching materials of programs, run by informal science education institution, don't contain enough script and activity for improving creativity and inquiring mind. As the result of the study, it is required that guidance plan of education program be developed with more activities, teaching method and script, to seek quality of class than quantity of that when developing education program of science education institutes. And it is required to develop teaching material using creative technique and to improve medium and long term program for development of feedback.

In this study, in order to use history of mathematics in mathematical learning effectively, we investigate application of history of mathematics shown textbooks in simultaneous equations. History of Mathematics can be used in order to enhance comprehension and increase interest in an introduction to the simultaneous equations. It also can be used to help motivate middle school students to solve the simultaneous equations with much interest during the development phase, and develope open thinking and reflective thinking in the enrichment learning.

This study attempts to analyse mathematical thinking and attitude of students related to mathematization in the problem solving process and provide implication of teachers' roles. For this, this study analyses mathematical thinking and attitude by dividing the process of solving problems of triangular array into several steps. And it makes a proposal for teachers questioning which can help students according to steps. Therefore this study results students' mathematization needs various steps and compositive mathematical thinking and attitude when students solve even a problem. From the point of view of teachers who attempt to wean students on mathematization, it is necessary for teachers to observe and analyze how students have mathematical thinking and take a stand for mathematics in detail. It also indicates that it is desirable for students who can not move on next step to provide opportunities to learn on their own rather than simply providing students mathematical thinking directly. Students can derive pleasure from the process of solving difficult problems through this opportunity and realize usefulness of mathematics. Finally this experience can build mathematical attitude and prepare the ground to be able to think mathematically.

In this paper I have tried to find the points which current Math teachers should reconsider in their classes and suggested how to improve the teaching methods in the class. For these answers, I analysed Teaching plans of 30 Math teachers in K province and observed their model classes. The conclusions acquired by these observations are the followings. First, Math teachers should have a great deal of enthusiasm in their classes. Second, Math teachers must understand the curriculum. Third, Math teachers have to understand their students. Fourth, Math teachers should endeavor with other teachers through the workshop. Fifth, Math teachers should be professional and open-minded to make their classes public anytime.

The purpose of this study is to investigate the pattern and characteristics of elementary school teaching and learning processes in science based classes. The study participants' class was recorded in video and instructional conversation transcription. The pattern of the observed class was analyzed using the classification frame suggested by Mogan &Saxton(2006). In result, the questioning for elicit information was most frequent and questioning for shape understanding and the questioning for press for reflection in its priority. In result, the presence of elicited questioning for the attainment of knowledge and understanding is more prominent in science-based classrooms. It was revealed that the participating teachers used the questioning sentence pattern more frequently and the self-sustained inquiry that accelerates creative thinking of the student was lacking. It was discovered that teaching elicited questioning, which accelerates creative thinking, as well as fact confirmation pattern is a necessary element of training for teachers.
