The purpose of this study was to analyze changing aspect of teacher and student's value in mathematics instruction. For this purpose, teacher and student's value are analyzed through value questionnaire by four times. The results of this study revealed that although value are individual's deep decision mechanism, it could change considerably by the time. Teacher wasn't compel students to follow her value. Rather, teacher was modified instruction goal to reflect students thinking what is important in mathematics lesson. First, in case of mathematical value, rationalism, objectism, mystery were convergent each other. And control was almost unchanged and openness has been onwards and upwards. Second, in case of mathematics educational value, understanding, pleasure, terminology and application were convergent each other. However achievement was almost unchanged. Also, to teach effectively, teacher using several kinds strategy while negotiate with student's value continuously. On the basis of these results, this paper includes several implications for the future study about values in mathematics which could be the critical factor in student centered instruction.

The purpose of this study is to support the understandings of teachers about the instructional strategies of collaborative problem solving and mathematical modeling as presented in the 2015 revised mathematics curriculum. For this, tasks of the Cubes unit from six grader's and lesson plans were developed. The specific problem solving processes of students and the practices of teachers which appeared in the classes were analyzed. In the course of solving a series of problems, students have formed a mathematical model of their own, modifying and complementing models in the process of sharing solutions. In particular, it was more effective when teachers explicitly taught students how to share and discuss problem-solving. Based on these results this study is expected to suggest implications on how to foster students' problem solving ability as mathematical subject competency in elementary classrooms.

Of computing skills in the field of multi-media, particularly augmented reality technology contents may provide realistic learning experiences with 3D pictures through the learners' manipulation activities. However, the marker systems in the existing studies were not well developed as to maintain the students' interest and concentration. In this study, we have designed the first lesson ("Earth and Moon") of 5th graders' science with augmented reality combined system so that we could deal with manipulation activities of the relationship between augmented objects, From the experimental study, using combined augmented reality contents made a significant difference in their learning achievement and motivation. Thus augmented reality combined system can be utilized for a variety of topics to maintain students' learning motivation.

This study aims to investigate high school students' misconceptions in the subject of Korean geography, and further to create categories to systematically understand the misconceptions. The researcher asked experienced geography teachers to produce a list of students' geographic misconceptions, and then classified the misconceptions. The following five categories were created: 1) self-centered understanding based on everyday life and experience, 2) confusion by words, 3) inappropriate applications of operational definition or geographic concepts, 4) naive inference, and 5) inflexible generalization. The validity of this classification was established through a panel discussion with experts in geography education. The misconceptions that belonged to the categories of naive inference and inflexible generalization occupied a great portion. The misconception list in this study provides a useful data-set for researchers whose interest lies in misconception, and geography teachers can devise a lesson plan that explicitly emphasizes correct geographic concepts to prevent students from establishing misconceptions.

In a EFL situation, most Korean students and teachers are exclusively dependent on English textbooks to acquire the cultural factors of English. Therefore, it is necessary to analyze cultural elements in the English Textbooks. The results of the study are as follows: First, although all of the textbooks contain the culture part at the end of each lesson, it is insufficient for students to build a cultural schema. Second, in the analysis of cultural types, three types of cultures are presented in a similar percentage. Third, the culture elements were analyzed based on the 7th national curriculum revised in 2011. The most dominant is the culture regarding arts and literature. Forth, in nationality analysis, universal culture takes up the largest portion. Therefore, it is required more efforts to improve students' knowledge of the American and English culture.

In this paper we have developed metadata system in order to utilize and refer to ICT educational resources which stand on the basis of standard international metadata " DC Core Education" by analyzing into the time input resources during each lessons. This metadata system makes addition metadata elements(introduction, development, review) in the flow of a general lesson to many ICT educational resources and high quality educational information in the web. It means elementary school teachers feel easy and convenient by offering systematically interface and unify reference. The system could expect to willing to help effectively lessons with ICT.

The purpose of this study was to investigate effects of nutrition education program and pamphlet for the lower grades elementary students focused on individual daily needed food exchange units using Food Exchange System. Program consisted of four lessons (40 min/lesson), "5 major nutrients & function", "6 food group and sources", "daily needed food exchange units for normal body weight", and "smart snack choice and exercise". Pamphlet as activity book was developed for the program. The subjects were 3rd grade elementary students (educated group, 31 vs. non-educated group, 31). Educated group were lessoned as group and/or individual. We examined the differences in nutrition knowledge, dietary attitudes, dietary intakes and satisfaction of the program and pamphlet. In educated group, there were positive improvements on nutrition knowledge score "function and foods of 5 nutrients" and on dietary attitudes "type of breakfast and snacks". In the evaluation of dietary intakes according to KDRI, there were positive improvements on intakes level of riboflavin, vit. C, folate, Ca, P, Fe and Zn in educated group. In satisfaction with the program and pamphlet, contents, font size, visual, figure, difficulty and program curriculum were over 2.90/3.0. It showed that the developed nutrition education program and pamphlet focused on individual daily needed food exchange units using Food Exchange System improved nutrition knowledge, dietary attitudes and nutrients intake level in the lower grades elementary students.

This research aims to suggest a math-based convergence instructional model. The convergence instructional model with emphasis on problem solving ability was developed based on each subject and the STEAM model. Then, the appropriateness and limit of the classroom model were investigated, through examining the aspects of its realization in each stage of the class instruction model while enacting a four part lesson on 6th graders. As a result, each stage of the classroom instruction model influenced in helping the students discover various problem solving skills, critically examine the process of the solving, and attain positive perspectives on the classroom instruction. However, appropriate intervention of the teacher was needed to lead the students to further synthesize the explored issues in mathematics and to expand the scope of their emotional experience. This paper closes with suggestions in implementing math based convergence lessons.

Through the systematic analysis on articles about the environment in newspapers, the news reports were considered as effective materials, so after being reconstructed, they were used as learning materials in a lesson on environment contamination which is newly introduced in Earth Science I from the 2009 curriculum revision. To examine students' attitude toward science, before and after NIE application to the students, Test of Science Related Attitudes(TOSRA) as a test tool was carried out which was composed of 7 categories - four optional questionnaires for each category, 28 in total were used. The result was as follows: in a pretest, based upon the average scores by factors the factors ranked from the highest to the lowest as follows: the social meaning of science, the acceptance of the scientific attitude, the commonness of a scientist, the attitude to scientific exploration, the pleasure in science class, the vocational interest in science, the concern over science as a hobby, and in posttest, their ranking as follows: the acceptance of the scientific attitude, the pleasure in science class, the commonness of a scientist, the social meaning of science, the attitude to scientific exploration, the vocational interest in science, the concern over science as a hobby. Also they were all statistically significant at a significant level p<0.05. However, the test revealed that there were some negative effects on the social meaning of science and the attitude to scientific exploration and therefore it is judged that in order to overcome those influences, some bright articles about solving the environment contamination should be applied to the lessons and be complemented effectively by experiments and various media: NIE as well as science magazines, data from Internet search and treatises on science.
