Logic and intuition are considered as the opposite extremes of teaching geometry, and any teaching method of geometry is to be placed between these extremes. The purpose of this study is to identify the characteristics of logical and intuitive approaches for teaching geometry and to derive didactical implications by taking Euclid's Elements and Clairaut's Elements respectively representing the extremes. To this end, comparing the composition and contents of each book, we analyze which propositions Clairaut chose from Euclid's Elements, how their approaches differ in definitions, proofs, and geometrical constructions, and what unique approaches Clairaut took. The results reveal that Clairaut mainly chose propositions from Euclid's books 1, 3, 6, 11, and 12 to provide the contexts that show why such ideas were needed, rather than the sudden appearance of abstract and formal propositions, and omitted or modified the process of justification according to learners' levels. These propose a variety of intuitive strategies in line with trends of teaching geometry towards emphasis on conceptual understanding and different levels of justification. Specifically, such as the general principle of similarity and the infinite geometric approach shown in Clairaut's Elements, we could confirm that intuition-based geometry does not necessarily aim for tasks with low cognitive demand, but must be taught in a way that learners can understand.

On the standards or elements of teaching evaluation, the Korea Institute of Curriculum and Evaluation(KICE) has carried out several research as follows : 1) establishment of observation elements for selecting examples of good instruction between 2001 and 2002, 2) development of the standards on teaching evaluation between 2004 and 2006, and 3) investigation on the elements of Pedagogical Content Knowledge including Subject Matter Knowledge between 2007 and 2008. The purpose of development of mathematics teaching evaluation standards through those studies were to improve not only mathematics teachers' professionalism but also their own teaching methods or strategies. Especially, the standards on mathematics teaching evaluation were developed based on the standards on general teaching evaluation. In this study, the standards were revised and modified by analyzing the results of those studies (namely, evaluation standards) focused on SMK. For this purpose, four domains such as the knowledge of curriculum reconstruction, knowledge of mathematical contents, methodological knowledge, mathematical value were new established based on the theories relevant to SMK and on the base of these four domains, standards or elements on teaching evaluation focused on SMK were reconstructed.

This study investigated how pre-service mathematics teaches' experience in microteaching influences their motivations toward teaching behaviors and changes by analyzing their teaching records and class reports. Although respondents planned to conduct various strategies pertaining to motivations, some of them were not used. Also, motivations toward their teaching behavioral changes leaded to positive aspects, but also leaded to negative ones. These findings imply that only two times microteaching experiences would not be sufficient to lead to positive teaching behavioral changes through their motivations. However, pre-service mathematics reported a high level of intention to change their teaching behavior through a comprehensive review process regarding their teaching. Therefore, teacher eduction institutions should develop well structured educational programs and apply them to pre-service mathematics teachers for a better understanding of their teaching and its review through motivations. In addition, providing opportunities for pre-service mathematics teachers to experience various educational programs including microteaching would be necessary for improving their teaching behavior through motivations.

The Korea Institute of Curriculum and Evaluation(KICE) has carried out the research on the development of the standards on teaching evaluation between 2004 and 2006, and particularly on the 'mathematics' teaching evaluation in 2006. The purpose of development of mathematics teaching evaluation standards is to improve not only mathematics teachers' professionalism but also their own teaching methods or strategies. The standards on mathematics teaching evaluation were developed based on the standards on general (not individual subject) teaching evaluation. They were revised and modified by analyzing the results of the interviews and survey with teachers about the adaptability of the standards in school. The standards were classified into four major areas of knowledge, planning, practice, and professionalism. Each area of these four were categorized into 6 smaller divisions and 36 elements. In addition, it was presented that brief descriptions on each teaching evaluation standards(element), guideline for evaluation methods, evaluator's observation index, and performance level with explanation for the standard achievement in four stages.

This study investigated the content and the effect of peer discussion about classroom practices on their science teaching. Participants included three science teachers with chemistry backgrounds in middle and high schools. Each of them had their classes videotaped and observed the footage as well as discussed the lessons together. The teachers had six meetings on 15 recorded lessons including one meeting beforehand. Teachers' discussions were also audio-taped and the data was transcribed. Teachers extensively discussed their lessons not only in terms of instructional strategies and scientific concepts but also the curriculum organization and teaching goals. Analysis of video-recorded lessons showed that instructional strategies were changed partially, but the aspects of curriculum organization in relation to teaching goals were not changed. Analysis of the recorded data revealed that teachers recognized the problems in their science teaching and considered the practical alternative ideas suggested by peers, but teachers proposed the necessity of experience to practice in their class. The study shows that observing and discussing each other's classes is one possible way to improve the class. Implications about teaching improvement for other teachers were discussed.

As a case study, we analyzed the professor's teaching professionalism in college of science-engineering based on pedagogical content knowledge. Two professors from the college of science-engineering located in Chungcheongbuk-do participated in this study. After collecting their syllabi, we observed their classes and conducted semi-structured interview before and after the classes. Analysis were conducted on their syllabi, taped videos, field notes and transcripts of the interview. As a result, both professors' orientation to teaching was not only related to learning subject matter knowledge, but also developing job competencies or communication skills. Their orientations were transformed according to the educational situation. After establishing the final learning goals, the professors organized weekly plan by listing the topics. However, they were unaware that the goals of each topic should be presented in detail in the class. Also, one of them presented a lack of understanding of the students' prior knowledge and showed low understanding of what aspects of the topics make students difficult to learn. In addition, the two professors applied various teaching strategies such as giving examples, questioning, and problem solving, but the degree of students' participation was not enough in the process of teaching. In the aspect of assessment, the professors had low understanding in students' achievement or feedback. Based on the results of the analysis, this study proposed methods and strategies for improving the teaching professionalism of science-engineering professors.

This paper addresses construction of a new network of invention education through the internet and creates a plan to apply it to practical invention education. We examined the status of invention education in Korea, the U.S., and Japan to consider problems of practical invention education and to draw a particular direction for the future invention education. Various papers, books, and documents related invention education were reviewed to make teaching and teaming strategies of invention education. Based on the analyses, criteria of teaching and loaming were identified as how to challenge teachers, students, parents, and administrators to successful implement invention education practices. Using the criteria of teaching and teaming, we designed a framework for a website and constructed a practical website concerned with invention education, including constructive components in the framework. This will require an experimental application during which teachers and researchers can do revisions and add supplementary information. This network system will provide practical information in regard to invention education and created a communications system for in charge of invention education.
