The purpose of this study was to investigate the nature of pre-service elementary teachers' metaphors on mathematics textbooks. Their metaphors describe individual and collective patterns of thinking and action on mathematics teaching and learning. To analyze their metaphors, qualitative analysis method based on Lakoff and Johnson's theory of metaphor (1980) was adopted. Metaphors on mathematics textbooks were elicited from 161 pre-service elementary school teachers through writing prompts. The writing prompt responses revealed three types and thirteen categories: As Type I, there were (1) 'Principles', (2) 'Summary', (3) 'Manual', (4) 'Encyclopedia', (5) 'Code', (6) 'Guidelines', and (7) 'Example'. As TypeII, there were (9) 'Assistant', (10) 'Friend', (11) 'Scale', and (12) 'Ongoing'. As TypeIII, there was (13) 'Trap'. Among these categories, 'Guidelines', 'Assistant', and 'Ongoing' were the most frequently revealed. These results indicate that the relations of mathematics curriculum, textbooks, and classrooms are not a unilateral way but should communicate with each other.

The purpose of this study is to examine the effects of small group discussion on elementary students' science writing. In this study, four 6th grade students were chosen from an elementary school in Seoul. Students were involved in eight science writing classes and the contents of a small group discussion and interactions were recorded and observed. Students' science works were collected and analysed based on three domains: scientific thinking, logic and originality. The result of this study showed that the contents of a small group discussion greatly affected the scientific thinking domain. A low-achieving student received lots of help from a high-achieving student. It was easy to improve in the logic domain through the science writing classes. Average students got good grades in an originality domain when the subject was related to their real life. A small group discussion would have an effect on science writing ability positively if the students acquired proper guidance on the procedure and manner of discussion. The science writing lesson would be more effective if the learning group was organized homogeneously in the aspects of intelligence achievement and interpersonal relationships.

The aim of this study is to investigate the change of science writing ability between pre and post-science writing which was written before and after argumentation activity and to show how argumentation influences the science writing ability. To fulfill this aim, eight 5th grade students were chosen from an elementary school. They were involved in the nine science writing themes which was compose of scientific contexts and social scientific contexts. Students' science works in argumentation and writing activity were collected and analysed based on four domains of framework for science writing ability: scientific thinking, logic, creativity and expression ability. The result of this study showed that the affirmative change of four domains of science writing ability on post-science writing written after argumentation was observed. Also, an affirmative change was observed in all of the scientific and social scientific themes. A lot of changes of the scientific writing ability were observed especially when the themes were familar to student. The degree of change depended on the level of the student, but overall it influenced all participating students with a positive improvement for their scientific writing ability. Students with high grade of academic achievement showed high improvement in science writing ability, but students who had low grade of academic achievement also showed a positive improvement in science writing ability.

As the value and importance of mathematical communication was recognized, mathematical communication in mathematics education has been strengthened more and more. Written communication as well as verbal communication is emphasized. On the other hand, storytelling is introduced for elementary students to learn mathematical concept more naturally and easily in the 2009 revised curriculum. So, we noticed that they are familiar with story. In this study, we analyze the story writing activity levels with a focus on story writing, and how to think about it. And we offer some suggestions about mathematical story writing activity.

This study aims to explore group inquiry using science writing heuristic in elementary school science. We observed and examined what elementary students experienced in their science classes and moreover how they used their data to support their claims in the view point of scientific epistemology. The research question of this study is 'what is the result of coherence measurement for figuring out the relationship between argument and ground in group inquiry activity?'. To solve the study question, one fifth-grade class at an elementary school was selected. Four lessons in group inquiry using a worksheet of science writing heuristic were videotaped and transcribed. It was found that the hours of group inquiry when students can discuss meaningfully occupied approximately 37 to 45%. When measuring coherence in each lesson by developing a scale from one to five to estimate the coherence of the work sheet designed, the total average was 3.424. It implicated that students had their claims supported by some of their evidences. Although the figure was not enough to assist that they found strong bonds between their claims and data, they started to move forward to epistemological approach in their science lab works.

Since textbooks for elementary school mathematics in accordance with the seventh curriculum are 'Class I' textbooks, which are used as one and only one textbooks throughout the country, the following aspects have been considered： In the legal aspect, the contents including the curriculum for mathematics asked of the Writing Committee by the Ministry of Education were reflected; in the aspect of theory of mathematics education, the textbooks are written in a way appropriate to theory of mathematics education; and in the aspect of application of reality, the textbooks are written to help improving mathematics education in classrooms. Therefore, the main frame of writing the textbooks is to make students feel proud enough to say "I have done mathematics", through helping students rationally solve problems surrounding them by themselves with their experiences and activities. In the above viewpoint the following sentence is reflected upon: "Hundred explanations are not equal to one manipulation activity."

The purpose of this study is the reorganization of the curriculum on the measurement, a part of the second grade math curriculum, for the improvement of the estimation capability in the elementary school students. Research questions were as follows: (1) how are the estimation capabilities of the students who have taken lessons on the diversified estimation strategies? and (2) how are the mathematical writing capabilities of the students who have taken lessons on the diversified estimation strategies? The study using reconstructed lessons was conducted on 18 second grade students in an elementary school located in Seoul. Results show that the students' estimation capabilities and have improved. They started to use 'about' when writing estimation results, different from writing the accurate measurements. Measurement errors were gradually reduced, ending up with a student who could accurately estimate exactly 1m. In addition, their estimation capabilities in using appropriate estimation strategy and writing skills describing the estimation strategy have improved.

The purpose of this study were to know the effects of making science newspaper activity on the science inquiry process ability of elementary school students and to analyse the writing context about their articles. The 33 sixth grader were participated in this program and they made 3 or 4 make a group, 9 groups made their own science newspaper. The results are as follow: first, there were statistically significantly differences(p<.01) on the basic science inquiry process abilities especially measurement and reasoning on making science newspaper activity. But there were no significantly differences on the integrative science inquiry process abilities; second, according to their articles on science newspaper, in personal context, they used many terms such as ecosystem, producer, consumer, decomposer, balance, but it was not personalized. And in social context, They pointed the cause and solution for the pollution and destruction in ecosystem, but it was superficial. Lastly in physical context, They used well their science concepts from class and format in newspaper in making science newspaper.
