There arc numerous techniques available to appraise pupil achievement in elementary school mathematics. The teacher must utilize a variety of approaches to assess pupil growth in the mathematics curriculum. Each evaluation technique has its strengths as well as weaknesses. Thus, a specific evaluation technique may be utilized as a check on other approaches to appraisal. Pupil achievement must be assessed in terms of stated relevant understandings. skills, and attitudinal objectives. It is not adequate to appraise pupil growth in terms of understandings objectives only. Pupils must also be assessed in terms of skills objectives. The understandings acquired by learners must be utilized; thus, skills objectives need to be stressed adequately in ongoing units of study in elementary school mathematics. Adequate emphasis also needs to be placed upon pupils achieving attitudinal goals. Desireable attitudes on the part of learners aid in achieving understandings and skills objectives. A defensible program of evaluation would then stress that pupil achievement be adequately appraised in terms of understandings, skills, and attitudinal objectives.

The purpose of this study was to seek desirable direction of science teaching and to present meaningful ideas for implementing the science curriculum and teaching materials by measuring the degree of the students' understandings on science and comparing it with those of American students. The researcher comprised 790 primary and middle school students for the study and administered them questionnaires developed by Trowbridge, Bybee, and Sund. The questionnaires were analyzed along with three categories such as science method, science theory, and the achievement of scientists. The researcher used t-test and ANOVA in order to compare the difference of their understandings in accordance with grades and gender, and later compared Korean students' understandings with those of similar aged American students administered by the National Assessment of Educational Progress (NAEP) The research loathed to the overall conclusions as follows; Both primary and middle school students' understandings on science revealed positive and appeared no significant difference in gender. And it is thought that science education was being carried out hopefully to enhancing Korean students' scientific literacy, therefore, science teaching like what is implemented to the classrooms currently should be kept on in future. On the other hand, it is necessary to change primary school children's understandings on attitude and value of scientists while to change middle school students' understandings on scientific processes by experiment. Also primary school children need to understand that scientists are willing to change their ideas when new information becomes known.

This paper presents an analytical framework of Conceptual Understandings of Earth Systems (CUES) that shows a relationship between disciplinary knowledge of Earth systems and the specific thinking skills required to understand that knowledge. This framework is developed through an extensive literature review of students' and teachers' understandings of earth systems concepts and systems thinking in earth science context. This study first presents the categories of disciplinary knowledge of Earth systems, Earth System Knowledge (ESK). This study then illustrates a relationship between categories of ESK and the ontological categories (Matter, Process, Systems) that has been used to study students' conceptual understandings of Earth systems. Finally, this study presents the CUES framework to show the relationship between disciplinary knowledge and thinking skills. The implications of using this framework for curriculum development, assessment, and teacher education and ESS research are discussed.

본 연구는 Gess-Newsome(1999)의 변형적 관점에서 수학교사의 수학적 이해와 잠재적 학생들을 가르치기 위한 지도방법 간의 관계를 면밀히 이해하고자 중등 수학교사 4명을 대상으로 질적 사례 연구를 수행하였다. 구체적으로, 대수식 쓰기 문제해결을 위한 발달에 핵심적인 이해를 조사 후, 연구 참여자들이 이에 주목하여 문제를 해결하는지 분석하였다. 나아가 대수식 쓰기를 지도하기 위한 수업을 예상하는 과정에서 나타나는 교수적 행동과 수학적 이해 사이의 연관성을 분석하였다. 분석 결과 KDU에 주목한 2명은 대수식 쓰기 문제해결에 성공했으나, 다른 2명은 가분수 상황을 그림으로 나타내거나 상호적 추론을 요구하는 문제를 어려워하였다. 또한 교사들이 구상한 대수식 쓰기를 지도하는 방법에서 확인된 교수적 행동은 그들이 문제해결 과정에서 주목했던 수학적 이해가 투영되어 있었다. 본 연구 결과는 특정 수학 내용에 대한 교사의 KDU와 교수 활동을 위한 지식과의 연결 사례를 제시함으로 교사교육 연구에 기여한다.

In this study, the relationships among learners' cognitive variables, motivational variables, and conceptual understandings in learning with analogy were investigated. The instruments regarding analogical reasoning ability, field dependence-independence, mental capacity, and logical thinking ability were administered. Some subtests (self-efficacy, expectancy, self-concept of ability, and value) of the Patterns of Adaptive Learning Survey were administered. After students learned with a worksheet that included analogy, a conception test regarding 'stoichiometry that included limiting reagent' was also administered. It was found that learners' conceptual understandings were significantly correlated with the logical thinking ability and the field dependence-independence among the cognitive variables, and the self-efficacy and the self-concept of ability among the motivational variables. The multiple regression analysis of the cognitive variables on conceptual understandings revealed that the logical thinking ability was the most significant predictor. The field dependence-independence also had predictive power. In the analysis of the motivational variables, the self concept of ability was the only significant predictor.

The purpose of this study was to examine preservice elementary teachers' understandings and instructional strategies about children's science misconceptions. The participants were sixty senior students from a national university of education located in the midwestern area of Korea. A questionnaire, developed on the basis of Gomez-Zwiep's semi-structured interview questions, was used. The results of this study are as follows: first, many of the preservice teachers showed appropriate understanding of 'definition of misconceptions' (96.67%), 'examples of misconceptions' (78.33%), 'resistance to change of misconceptions' (71.67%), and 'impact on instruction of misconceptions' (91.67%), except for 'sources of misconceptions' (45.00%); second, although almost all the preservice teachers (96.67%) appreciated the necessity of identifying children's misconceptions before instruction, 43.33% of the preservice teachers did not show appropriate understandings on when and how to identify children's misconceptions; third, most of the preservice teachers (81.67%) were generally aware of instructional strategies to address children's misconceptions.

Pre-service teachers' understandings on magnet was investigated through the questionnaire method. The questionnaire was composed of 17 questions about the strength of magnet, the magnetized object and the direction of magnetic field around magnet. In this investigation study, 225 pre-service teachers were selected through random sampling method, who were sophomores in a National University of Education. The formation rate of the scientific conceptions on the strength of magnet was 30.3% and that on the direction of magnetic field around magnet was 53.9%. The average formation rate of scientific conception of all questions on magnet was 44.13%, which doesn't seem to be high as expected. It shows that many of subjects of the questionnaire don't understand fully the concept of moleclar magnet model and the superposition effects of magnetic field around magnet. The formation rate of the scientific conception on magnet of females who took courses in sciences in high school were higher than that of females who took courses in arts in high school, which had meaningful difference (p<.05).

The purpose of this study was to investigate science teachers' understandings about scientific argumentation in the classroom. Seven structured interview protocols were developed, asking the definition of scientific inquiry, the differentiation between scientific inquiry and hands-on activity, the opportunity of student argumentation, explicit teaching strategies for scientific argumentation, the critical example of argumentation, the criteria of successful argumentation, and the barrier of developing argumentation. The results indicate that there are differences and similarities in understandings about scientific argumentation between two groups of middle school teachers and upper elementary. Basically, teachers at middle school define scientific inquiry as the opportunity of practicing reasoning skills through argumentation, while teachers at upper elementary define it as the more opportunities of practicing procedural skills through experiments rather than of developing argumentation. Teachers in both groups have implemented a teaching strategy called "Claim-Evidence Approach," for the purpose of providing students with more opportunities to develop arguments. Students' misconception, limited scientific knowledge and perception about inquiry as a cycle without the opportunity of using reasoning skills were considered as barriers for implementing authentic scientific inquiry in the classroom.

Nowadays we needs the ship design ability strongly for our shipbuilding industry to attain the 2nd position among the competitive world marine industries. But we have short experience in ship design, so several ship design terminologies are used without clear understandings. Here, papers on ship design procedure and design methodology are summarized with some investigation about our present status. In addition, the state arts and new developments of Computer Aided ship Design in advanced ship building countries are treated. It is hoped that we-ship designers of our country-do have common understandings about the ship design terminologies.
