Through quantitative video analysis of four algebra classes and statistical analysis of various types of teacher evaluation behavior in the classroom teaching, we get: (1) Teacher evaluation behavior in classroom is close to take 1/5 of the total time of the classroom teaching, and it appears most frequently in class exercises and take the longest time; (2) There are many forms of teacher evaluation behavior in classroom, and most of the behaviors are positive assessment; (3) Recognition evaluation is relatively conservative in a single form without losing fairness; (4) Classroom assessments of teachers' behaviors are primarily concerned about students' knowledge and skills mastery, and it is less involved in student feelings, attitudes and behaviors; (5) The correct teacher evaluation behavior in classroom will inspire students to create internal motivations; and (6) The correct teacher evaluation behavior in classroom can stimulate the potential of students.

In this Study, I concerned the learning-teaching of the use of letters in algebra. Our Study can be summarized as follows; First, I tried to establish the theoretical Foundation necessary for the learning-teaching of the use of letters in literal expressions. Second, I made a course of study that leads to the understanding of the meaning and the use f literals in algebraic expressions. Third, Based on this course of study, I held classes on First-grade students in middle school and I carried on an investigation their understanding of the meaning and the use of literals in algebraic expressions. Finally, I made an analysis of findings in this investigation and identified student's a better understanding of the meaning and the use of literals in algebraic expressions.

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.

The purpose of this research is to study the effectiveness of applying Information technology to education, so-called education informatization. Education informatiantion consists of building information infrastructure, educational course operation and improvement of the teacher's ICT ( Information and Communication Technology) ability to consolidate and teach educational information development and diffusion. In this study, we've studied the effects of the use of IT on the improvement of student's class Participation and understanding level, We set the hypotheses and tested them. A method of teaching and learning using IT influences the degree of class participation. Educational courses and a method of teaching and learning have been proved to affect the understanding of a lecture. Also, we validated the educational effectiveness on the educational course and class teaching by setting WIS (Weighted least square) on the IT utilization time.

It is important that the teacher, in an inquiry learning gives his student sufficient thinking time regarding the teacher's question and the child's response. In an inquiry loaming, it is essential that children should have an enough time to understand question fully and find out correct answers. The purpose of this study is to investigate an effect of science teaching, when Wait-time theory is applied, on the scholastic and thinking ability, thinking trend and scientific attitudes of elementary children. We could draw several meaningful conclusions from the study concerned with improving the effect of science teaching that changed from teacher centered teaching to children centered erie.

The aim of this study is to analyze critically the meaning of 'good instruction'. In this article, the researchers emphasized the activities of teaching and learning as two essential elements of good instruction. The antecedent studies on good instruction have limitations in that they regarded good instruction as an instrument rather than valuable activity itself. This study consisted of three parts. Firstly, the researchers tried to clarify the meaning of good instruction underlying antecedent studies on instruction. Secondly, the researchers tried to analyze characteristics of good insturction suggested by antecedent studies. Thirdly, the researchers attempted to define a new meaning of good instruction. A new meaning of good instruction should be defined in accordance with characteristics of three commonplaces composing instruction such as teaching activity, learning activity and good interactions between teacher and learner. Good instruction can be defined as followings. Good instruction means an instructional activity which can change the student's meanings of experience as a result of interactions among teacher, learner, and educational materials.

To reveal secondary teachers' in-service education needs, in-depth interviews were conducted with 15 individual teachers based on semi-structured questions and qualitative data analysis procedures were adopted. They wanted to have; a. more knowledge of one's subject, subject related information, culture and common sense, counseling psychology, foreign language, and the 7th curriculum, b. better skills of student-centered teaching-learning methods, guidance and class management, good use of computers, and educational evaluation, c. improved attitudes regarding democratic problem solution processes, conversation with and service to students from their viewpoints, commitment to preparations for teaching, educational innovation and improvement, elimination of improperness, and pride of teaching job.

Science has developed along with human society and history. In today's society ruled by pluralism, an educational approach using the historical materials which represent their own cultures will make science education more effective. The purpose of this study was to search for the meaning of science education related with a history of science, and to suggest the possibility for science education based on Korean history of science. The conclusions of this study is below: (1) The history of science is useful to teaching science in K-12 setting. That is because it was helpful to make a scientific concept and to invite student's interest about learning science. Moreover, it was most suitable to teach the nature of science as well as the relation between science and society. (2) A model which consists of 15 types of science education materials using Korean history was suggested. This model plays a potential role as a R&D framework of developing teaching & learning materials based on the history of Korean Science.

In this paper, we present a new environment of learning and teaching of trigonometric, exponential and logarithmic functions, the most difficult parts for students to learn among functions, through sound and music, students like the most. First, by using sound and music, we try to arouse student's interest. Second, we let students see and hear properties of transcendental functions so that students can understand and remember them easily. Finally we encourage students to compose their favorite song using transcendental functions so that they can experience the practicality of transcendental functions.

In this paper we discuss the Socratic method from the aspects of subject education and examine the meaning of the method in mathematics education that is the most suitable subject for the realization of the Socratic method. In addition, as a realization of the Socratic method, we conducted a teaching-learning experiment of complex natural exponential function with a 2nd year college student. The results of the experiment are analyzed with the intention of improving instruction of the complex analysis that is one of the college mathematics courses.
