The purposes of the study are to investigate the experiences of major stakeholders (i.e. science teachers, program instructors, local experts, etc.) who participated in implementing Community-Based Socioscientific Issues Programs (SSI-COMM) and to provide educational implications for further implementation. SSI-COMM dealt with three issues (i.e. abandoned pets, fine dust, and recycling) that students often encountered in their local community. Each program, lasting over 16 class periods in a free semester, included in-school and out-of-school activities in order to promote their interest and participation in community. Four teachers, four program instructors, and six local experts joined the interviews to explain their experience of participating in the programs. As a result, school teachers, program instructors, and local experts positively appreciated their experiences of the program implementation and perceived educational potentials of SSI-COMM. All the stakeholders mentioned that they became more interested in local socioscientific issues and strongly perceived the need for the implementation of such programs linked to their own community. The science teachers appreciated the opportunities to identify students' potentials through SSI-COMM and believed that SSI-COMM would contribute to reducing the gap between learning and practice. The program instructors, observed that out-of-school activities contributed to enhancing students' self-confidence and fulfillment in learning. Finally, the local experts obtained a sense of belonging to their community and were very satisfied with their contribution. The SSI-COMM programs are expected to be one of the educational models that will help to encourage the participation of students and stakeholders in facilitating educational activities in relation to the community.

This study is to review the content organization and developmental ways of the unit on the mixed calculations and explore the alternatives on the basis of students' responsive examples and error patterns with relation to the mixed calculations, mnemonics of PEMDAS and historical context with relation to the order of operations. Then I analyzed the textbook and manual for teachers of the unit of mixed calculations of fourth grade and improvement about teaching the mixed calculations. First, I pointed out illogical connection between practical problem and rules of order of operations. Second, I suggested constructing a textbook by considering conventional character of order of operations. Third, I pointed out the importance of structural understanding of an expression of mixed calculations and various strategies with relation to teaching and learning. This study is suggestive for textbook development of the mixed calculations.

In most curricular model for gifted children, independent study is included as an important element for developing students' study ability and producing creative production Gifted children also prefers this style of learning and they study more easily and with more fun when they learn in the learning style they prefer. This study aims to find out how gifted children in math area performs independent study and how teachers who teach them recognize independent study; survey study was used to analyze the reality of the production in relation to independent study. In result, gifted children's independent study ability was rather very low and teachers recognized the necessity of independent study but lacked understanding of the method of independent study.

The purpose of this paper is to survey the major elements that have changed English from a synthetic language to an analytic one. Therefore, this paper has looked at the differences between synthetic languages and analytic ones. In synthetic languages, the relation of words in a sentence is synthetically determined by means of inflections, while in analytic languages, the functions of words in a sentence are analytically determined by means of word order and function words. Thus, Old English with full inflectional systems shows the synthetic nature. However, in the course of time, Old English inflections came to be lost by phonetic changes and operation, which made English dependent on word order and function words to signal the relation of words in a sentence. The major phonetic changes that have shifted English are the change of final /m/ to /n/, the leveling of unstressed vowels, the loss of final /n/, and the decay of schwa in final syllables. These changes led to reduction of inflections of English as well as the loss of grammatical gender. The operation of analogy, the tendency of language to follow certain patterns and to adapt a less common form to a more familiar one, has also played an important role in changing English.

This paper critically reviewed the role of negative feedback in second language acquisition with a focus on recasts based on the findings of recent research investigating the effects of recasts on second language acquisition. First, recasts as negative feedbacks or negative evidence were reviewed in terms of Pinker's four criteria: the evidence of existence, availability, use, and necessity of recasts in second language acquisition. Second, the issue of the nature of recasts, whether they have benefits in SLA as a negative or positive evidence, was discussed with reference to Leeman(2003)'s research findings. Then, in relation to availability and use of recasts, the issue of the extent that they are noticed by learners was reviewed based on the findings from Philp(2003)'s study. Finally, the limitations of these two studies and the research orientation of future study were mentioned.

The purpose of this study was to analyze effects of child's age, language ability, social competence, parenting style, and socioeconomic status on preschoolers' theory of mind. The subjects were selected randomly from kindergartens and composed of three hundred 3-, 4-, and 5-year-olds and their parents and teachers. The data was analyzed by analysis of covariance and t-test. The major findings of this study were summarized as follows: it was found that language ability, parenting style, SES, and social competence had a positive effect upon preschoolers' theory of mind. This relation remained significant with children's age controlled. Children's theory of mind was more strongly related when their parents were highly affectionate with their children, children's language ability was greater, parents held higher socioeconomic status than those who had less prominent one, or children with higher social competence.

In this paper, we describe the design and implementation of the FDRA(Fault Detection Recovery based on Agent) running on distributed multimedia environment. DOORAE is a good example for distributed multimedia and multimedia distance education system among students and teachers during lecture. It has primitive service agents. Service functions are implemented with objected oriented concept. FDRA is a multi-agent system. It has been environment, intelligent agents interact with each other, either collaboratively or non-collaboratively, to achieve their goals. The main idea is to detect an error by using polling method. This system detects an error by polling periodically the process with relation to session. And, it is to classify the type of error s automatically by using learning rules. The merit of this system is to use the same method to recovery it as it creates a session. FDRA is a system that is able to detect an error, to classify an error type, and to recover automatically a software error based on distributed multimedia environment.

Almost every children are naturally non competitive, so they have test anxiety. Because grading in paper-pencil tests is related to competition with their friends. Intense competition should not be a part of the classroom environment. This study intends to reflect current standardized tests(summative evaluations) in an elementary school mathematics(2008) and reconstructed it's problem. Teachers should provide students with rich situational problem-solving opportunities. Therefore we conclude "summative evaluation are consisted of some large problem type which contain some subproblems, or from easy(simple) problem with relation to difficult problem)".

The purpose of this paper was to take an in-depth look at early American English around the $17^{th}$ and $18^{th}$ century when immigrants from different European countries started to move into the New World. The paper attempted to describe early American English in relation to the process of immigration and settlement from a historical perspective. With a focus on major features of early American English such as uniformity, archaism and richness of lexicon, the paper tried to answer the questions such as how settlement influenced the formation and distribution of regional dialects across the continent, why immigrants tended to show a preference for a uniform way of speaking rather than choosing a variety of regional dialects for communication, and what role foreign languages played in the development of early American English. The overall findings based on the answers to these questions showed how American English went through a variety of processes and changes at the early stages of its development to become a national language later. The paper concluded with some remarks about the implications of the findings for EFL learning and the direction of future research on early American English.
