The problem solving processes of elementary school children who are talented in science have been seldom studied. Researchers often resort to thinking aloud method to collect data of problem solving processes. The major purpose of the study is investigating high ability elementary school students' problem solving processes through the analysis of written responses to science problems in everyday context. 67 elementary students were participated Chungcheongbuk-do Elementary Science Contest held on October, 1997. The written responses of the contest participants to science problems in everyday context were analyzed in terms of problem solving processes. The findings of the research are as follows. (1) High ability elementary students use various concepts about air and water in the process of problem solving. (2) High ability elementary students use content specific problem solving strategies. (3) The problem solving processes of the high ability elementary students consist of problem representation, problem solution, and answer stages. Problem representation stage is further divided into translation and integration phases. Problem solving stage is composed of deciding relevant knowledge, strategy, and info..ins phases. (4) High ability elementary students' problem solving processes could be categorized into 11 qualitatively different groups. (5) Students failures in problem solving are explained by many phases of problem solving processes. Deciding relevant knowledge and inferring phases play major roles in problem solving. (6) The analysis of students' written responses, although has some limitations, could provide plenty of information about high ability elementary students' problem solving precesses.

이 연구에서는 해결자 청취자 활동이 예비 화학교사의 지필평가문항 제작 과정에서 고려된 교과교육학 지식(PCK) 구성 요소 사이의 상호작용에 미치는 영향을 조사하였다. 2명의 예비교사로 구성된 4개조의 해결자 청취자 활동을 통한 지필평가 문항 제작 활동을 분석한 결과, 해결자와 청취자 역할과 상관없이 PCK 구성 요소 중 과학 평가에 관한 지식 측면을 가장 많이 고려하였으며, 과학 내용에 관한 지식과 학생에 관한 지식 측면에 대한 고려도 비교적 많았다. 그러나 과학교육과정에 관한 지식과 과학 교수 전략에 관한 지식을 고려한 경우는 적었다. PCK 구성 요소 사이의 통합 수준에서는 PCK 구성 요소 중 2가지 측면 또는 3가지 측면의 통합이 다양한 유형으로 많이 나타났으며, 4가지 및 5가지 측면의 통합도 일부 나타났다. 그러나 과학교육과정에 관한 지식 측면 등을 포함한 통합은 비교적 적었으며, 과학 교수 전략에 관한 지식 측면을 포함한 통합은 매우 드물었다. 이를 통하여 예비교사의 지필평가 문항 제작 능력 신장 및 PCK 계발전략으로서 해결자 청취자 활동의 유용성, 제한점, 효과적인 활용방안에 대하여 논하였다.

문장제 문제는 단순한 수학적 수식으로 구성된 연산문제와는 달리 언어적으로 표현된 문제 안에서 수학적 내용을 찾아 그것을 수식으로 표현하는 과정을 필요로 한다. 이는 고차원적인 인지적 전략을 요구하며 학습자는 수학적 사고력과 추론능력, 이해력, 언어와 읽기 등을 고루 활용해야 한다. 하지만 대부분의 학습장애학생들은 문장제 문제를 해결하는데 어려움을 겪고 있다. 본 연구에서는 학습장애학생이 인지적 과부하를 적게 받으면서 인지적 전략을 학습할 수 있으며 또한 학생들에게 전문가의 예시를 단계적으로 제시하는 WOE (Work-Out Examples: WOE) 기반 스마트러닝 학습시스템을 제시한다. 본 시스템의 특징은 다음과 같다. 첫째, WOE를 순차적으로 따라하면서 학습자는 인지적 부하 없이 자연스럽게 문제해결전략을 습득할 수 있다. 둘째, 학습자의 학습 동기를 높이고 흥미를 유발시킨다. 셋째, 시공간을 초월한 학습이 가능하기 때문에 학습자 스스로 학습을 조절하는 자기주도적 학습능력이 향상될 수 있다. 본 시스템의 적용결과는 다음과 같다. 첫째, 학습장애학생의 수준에 맞는 학습 단계가 제공되고 지속적인 피드백이 있기 때문에 학습자의 개별화학습이 가능하였다. 둘째, 학습자들이 학습내용을 자연스럽게 습득함으로써 문장제 문제해결능력이 향상되었다. 셋째, 학습과정에서의 성공경험으로 인하여 학습에 대한 자신감 및 학습동기가 향상되고 긍정적인 자아개념이 형성되었다.

In this paper, we investigate the comparative effectiveness of two kinds of instructional methods in transfer of mathematics learning: one based on the situated cognition, i.e. situated learning (SL) and the other based on traditional learning (TL). Both classes (of grade 2) studied addition and subtraction of 3-digit numbers. After that, they completed two written tests (Written Test 1 included computation problems, Written Test 2 included computation problems and story problems) and a real situation test. As a result, no significant differences were found between the two groups' performance on computation skill in Written Tests 1 and 2. But the SL group performed significantly better on the performance of story problem and real situation test than TL group. This result indicated that the SL made improvement in transfer of mathematics learning. As a result of interviews with 12 children of the SL group were able to use contextual resources in solving real situation as well as story problems.

The issues concerning the nature of the attitude toward the study of national language may vary from country to country, depending on the national or racial characteristics. The problem domains and the methodologies dealing with them may vary accordingly. Ever since the Korean language was equipped with a writing system in the year of 1443 through King Sejong's long-cherished desire, investigations have been constantly made into the real nature of the language itself in pursuit of a better method for representing the spoken language in written form. This is how the study of the Korean language began to take shape. Among such investigations are Hunmin-jeong-eum(the Korean script: 1446) compiled by Jiphyon-jon, the royal office of schloarly researches, Doongguk-jeonghun-yokhun (the orthodox script of Korean: 1448), Hongmu-jeonghun-yeokhun(interlinear gloss for the Chinese script of the Ming Dynasty: 1455), An Orthodox Approach to Written Korean (1909) by the institute of the National Script, Re Standardized Spelling System (1933) by Chosun Language Society, An Authorized Dictionary of Standard Korean (1936), How to Write Borrowed Words(1940), and A Grand dictionary of Korea (1947-57). Chu Shi-Gyung's Phonetics of the Korean Script(1908), Korean Grammar(1910), and Sound Patterns of Korean(1914) were all written in this vein; so was Choi Hyun-Bae's Uri-mal-bon (the rudiments of Korean Grammar: 1929/1937). All these achievements in the study of the Korean language are the end-products of the constant endeavor to solve the issues related to the spoken and written farms of the Korean language. And this is how the uniqueness and autonomy of the language study in korea have been established. It should be borne in mind, however, that, in seeking solutions to the problems inherent in the Korean linguistic studies of foreign countries. On the contrary, they have been very active in accommodating such results. While they have set up their problem domains on the basis of the korean language, they been progressively open-minded in looking for the solutions to the problems at hand.

This study investigated university students' (majoring physics education) understanding of some aspects of idealization frequently used in teaching and learning of physics, especially of mechanics. A total of 143 students were given a Questionnaire of six questions requiring written responses. Out of the six questions, the first three were concerned with basic idealized concepts, the next two with the making of the assumptions of ideal conditions for given problem settings, and the last with the identification of the idealization used in the given solution of a problem. Students' written responses were grouped into patterns and the relative frequencies of the patterns were counted. It was found that the students had limited understanding of the idealization and their ideas were diverse and frequently incorrect. The implications of the findings are discussed in relation to the roles of idealization in physics education.

For human beings, language is the most important means of communication. Bloom and Lahey see successful language development as an interaction between form, content, and use. Language knowledge is a social phenomenon produced in a socio-cultural environment through interaction. Teachers have traditionally concentrated on the structure of their student's writing rather than on the message. If writing is to be seen as an interactive social process between humans, it is the content which is responded to. Language acquisition could be a major problem for hearing-impaired children and their acquisition of written language is characteristically problematic. This study is to search the use of microcomputers in written conversational methods, which enable the hearing-impaired student to hear their conversations in a visual form and which usefully extend their written language learning opportunities.

These days, with the emphasis on statistical literacy, the importance of communication is the focus of attention. Communication about statistics is important since it is a way of describing the understanding of concepts and the interpretation of data. However, students usually have trouble with expressing what they understand, especially through writing. In this paper, we examined preservice teachers' difficulties when they wrote about statistical concepts. By comparing preservice teachers' written responses and interview transcripts of the variance concept task, we could find the missing information in their written language compared to their verbal language. From the results, we found that preservice teachers had difficulty in connecting terms contextually and conceptually, presenting various factors of the concepts that they considered, and presenting the problem solving strategies that they used.

This study was performed to survey the achievements in problem solving by the inquiring experiment, which was done by the superior group in the traditional cocepts-centered written tests. The purpose of this study was to identify characteristics of inquiring experimental assessment by analyzing differences between concepts-centered written and inquiring experimental tests. The subjects of this study was 211 applicants. They are the superior group of the 9th grade students, and score in the top 1% of total achievements percentage in school. They also have passed the primary entrance examination. The inquiring experimental test was developed according to the curriculum in school, and is composed of 5 subcategories: problem-perception and formulating hypothesis, designing an experiment, carring out an experiment, recording data and drawing conculsion, and generalizing conculsions and communicaton. The checklists of each subcategory were made and testing methods were divided into observation and report. The major results of this study are as follows: 1. The achievements in each subcategory of inquiring experimental performance were very low in the superior group who took the concepts-centered written tests. 2. The results of factor and correlation analyses in this study confirmed the abilities measured by inquiring experimental assessment differed from abilities measured by existing tests. These results indicated that even students who achieved high in scientific knowledge, these abilities were not automatically transformed inquiry process which many other abilities were integrated into. Therefore, problem solving ability requires integrated abilities which are fostered by inquiring experimental tasks. This suggests that new instrument for assessment must be developed to measure integrating ability especially where scientifically gifted students are selected, or where entrance examinations to the science schools are administered.
