In the present study, the changes of mathematics teachers' verbal feedback between ten years ago and later were examined using a coding scheme on the types of teacher verbal feedback. Based on the analysis, it is found that teachers intend to use encouraging strategies to make responses to students ten years later. In addition, the duration used in communication between the teacher and individual student is being longer while the frequency of communication becomes less compared ten years ago. Meanwhile, the difference between good lesson ten years ago and common lesson ten years later is not so apparent. It can be inferred that the quality of teaching has being developed.

In this paper I attempt to survey on the theories of observation and analysis of mathematics classroom discourse. In order to discuss applicability of the theories I look at preservice teachers' observation of mathe-matics classroom and teachers' conception of mathematics lesson. In examining reports from preservice teachers' I identify how they understand mathematics lesson and how the theories can enhance their understanding. Not surprisingly, there are lots of obstacles for teachers to practice mathe-matics educational theories. 1 find some features of their efforts or attempts to overcome the obstacles in an attempt to gain insights into alternative ways of concep-tualizing the methods of observation and analysis through the interview and the discussion with teachers.

The purposes of this study were to review developmental stages of acculturation, to establish dimensions and components of intercultural communicative competence, and to suggest teaching methods in the elementary school based on the dimensions and the components of the stages. In order to achieve these purposes, theoretical research on the nature of intercultural communicative competence and teaching methods of intercultural dimensions and components was carried out in terms of developmental stages of acculturation. The stages of acculturation have relation to cognitive domain, affective domain, and cultural awareness. In the domain of cognitive development, the models such as Cummins (1981), Wong-Fillmore (1983), and Ausubel (1968) were presented. In the affective domain of second language research, the models of Gardener and Lambert (1972), Maslow (1954), and Bloom (1974) were argued. Modifying the models of Ausubel, Cummins, Wong-Fillmore, the dimensions and components of intercultural communicative competence were established. In addition, it was suggested that cultural syllabus and lesson plan based on tourist and survivor stage should be considered.

The purpose of this study is to help the students in middle school improve their English listening comprehension by presenting effective teaching and learning techniques using animation. A good animation provides a self-contained world with language expressed in a virtual context. A few animation such as "Mulan", "The Emperor's New Clothes", and "Gulliver's Travel" are presented. The materials are primarily for English listening comprehension, enhance awareness of American culture and life-styles, and to encourage students' active role in learning English. It is suggested that their use with content-based instruction, where animation provides relevant schema background, makes language relevant and comprehensible. Practical aspects of classroom instruction are discussed, focusing on the adaption of pre-viewing, while-viewing, and post-viewing activities to the selected animation. It is concluded that careful animation selection, purposeful lesson planning, and the integration of pre-viewing, while-viewing, and post-viewing activities into the content-based lesson encourage natural language skills, especially the listening comprehension and students' interest in English.

This article introduces a proposed lesson to help younger or lower level mathematics students conceptualize area. The objective for the proposed lesson was for the student to demonstrate an understanding of the concept of area by identifying the area, in square units, of polygons drawn on computer dot board constructed by computer software, Geometer's Sketchpad. The concept of covering is the key to develop the concept of the area. The article proceeded from rectangular figures, to right-triangular figures, to non-right triangular figures, then to polygons to find the area and develop the formula for the area of the figures. It is meaningful that this kind of materials can be developed within interactive computer environment since students feel successful in loaming and teachers use them directly in their measurement classes.

This study engages in the features of interaction in elementary school mathematics lessons as reflected in the class discourse. 28 pre-service teachers documented the discourse during observation of their tutor-teachers' lessons. Mapping the interaction patterns was performed by a unique graphic model developed for that purpose and enabled providing a spatial picture of the discourse conducted in the lesson. The research findings present the known discourse pattern "initiation-response-evaluation / feedback" (IRE/F) which is recurrent in all the lessons and the teacher's exclusive control over the class discourse patterns. Hence, the remaining time of the lesson for the pupils' discourse is short and meaningless.

This paper shows that novel engineering (NE) is a creative learning process (CLP) based on Seymour Papert's constructionism. First, the paper introduces NE, CLP, and constructionism. Next, a sample NE lesson is explored. NE is an innovative way of integrating literacy into an engineering discipline that was developed by the Center for Engineering Education and Outreach (CEEO) at Tufts University. NE consists of seven steps: picking a book, identifying problems, designing solutions, building, feedback, upgrading solutions, and reconstructing stories. Lifelong Kindergarten by Mitchel Resnick of the MIT Media Lab describes CLP, and the four elements necessary for a lesson to be creative. NE can be viewed as one of the most creative, comprehensive learning models ever developed. NE integrates several paradigms in Korea, following all the constructs of both CLP and constructionism. The aim of this paper is to show that NE is based on both CLP and constructionism.

The purpose of this study is to figure out how teachers conduct an experiment in measuring the size of the Earth and how students recognize it. For this study, an in-depth interview was conducted one week after the lesson on the experiment about measuring the size of the Earth. The participants were five secondary school teachers and five secondary school students. The in-depth interview was recorded and transcribed. The result of the interview was drawn through an inductive categorized analysis method. As a conclusion of this study, the teachers taught the students the lesson using alternate angles instead of using the altitude of the Sun. Their lessons were based on Eratosthene's story or some related illustrations suggested in the textbook and not based on an explanation of the principle. Also, students measured the Earth's size only by using alternate angles and didn't understand the meaning of the shadow in the experiment. The results of this study show that teachers need to reconstruct the textbook and understand the accurate experimental principle for the students to have a meaningful experience of the experiment on measuring the size of the Earth.

The purpose of this study is to understand teaching and learning mathematics in elementary school classroom by considering mathematics as a kind of social practices and mathematics classroom as a kind of community of practice. The research questions of this study are as followings: 1) Which kinds of lesson organization reveal? 2) Which kinds of social participation structure reveal? 3) Which processes of making meaning reveal? This study was based on ethnomethodology. It was executed participation observations, interviews and surveys with teacher and 5 graders to collect the data related to the social practices formed their classroom. The social practices of mathematics classroom was analyzed from three aspects such as lesson organization, social participation structure and making meaning. The results from which we analyzed the social practices of the mathematics classroom are as followings. From the aspect of lessons organization, the teacher had a lot of power and authorities in the classroom and used them to elicitate students' responses. From the aspect of social participation structure, five SPSs(social participation structures) which revealed in Jo(1997)'s economics classrooms, were shown in this mathematics classroom, but there were a difference to the situations or frequencies which the SPSs appeared. From the aspect of making meaning, it was common that meanings are formed by the explanation of the teacher, but the teacher didn't deliver the mathematical meanings directly. She tried to interact with students to arrive shared meanings.

This study was aimed to find the impact of science lessons using e-NIE on science process skills and scientific attitudes of elementary students in comparison with that of traditional lessons. Subjects of this study were 5th graders from two separate classes at a elementary school located in U city. And the experiment has been conducted throughout 10 lessons for the duration of total 12 weeks, where one class, experimental group, attended e-NIE based lessons, while the other, comparative group, with traditional lessons for the same period, in an effort to collect both pre and post test results to compare. Findings from this study were briefly listed below: Firstly, e-NIE applied lessons were more effective in improving science process skills than traditional lessons, especially in the domain of integrated science process skills, with meaningful difference. Secondly, lessons combined with e-NIE enhanced scientific attitudes of elementary students more than traditional lessons with meaningful difference.
