The science teaching materials in primary schools are very important to stimulate the curiosity of the children, and to advance their science inquiring process, and especially to educate effectively the children who are in the stage of concrete operations. This thesis is an analysis of the research on the actual state of administration of the science teaching materials in primary schools in Choong Buk Province. According to the analysis, the administration of the science curriculum is found difficult, that is, only 32% of the required materials had been prepared a very poor ratio. In addition, the difference of the preparations between city and rural schools is very significant is, 39% in city and 25% in rural. Between the city and rural schools, the correlation coefficient of the order difference(Spearman's ρ) is 0.49%. (the order is determined according to the great ratio of each prepared material to required). Therefore, We can tell that there is no great difference of the order according to the territory. We know that the preparation of new science teaching materials for use in the classroom is at a lower rate than the preparation of other teaching materials, whereas, the preparation is going to large in its degree according to their use, year by year. It appeared that most schools do not consider not only the using frequencies of the teaching materials, but also the needed amount of materials in a class. When retraining coursework opens, We will instruct the primary schoolteachers in the importance of the science teaching materials and in the differentiation of their usage. Lastly, the school administration should be assisted financially for the least quantity of materials necessary, and studied further for the methods of effective use.

This paper is the result of a petrochemical study on the Jongam granite mass which intruded metasediments of Ogcheon zone, locating about 10km northwest from Miweon town, and the mass is $2.5km^2$ in area. In this study, the granite was petrographically analysed in such ways, modal analysis, myrmekite analysis, petrochemical study analysis and tectonic analysis of joint system. The findings are as follows: 1) The area of the granite distributed is a basin surrounded by metasediments. The granite is magma origin. 2) The major mineral composition of the granite are quartz, plagioclase, microcline orthoclase and biotite, and accessaries are muscovite, sericite, magnetite, zircon and sphene. 3) In triangles of $Qu-K{\cdot}fp-PI$, Bi-Or-Hb+Mt and Qu-Ab-Or, the data point areas are similar to those of the NW zone of D.S. Lee (1971) 4) The granite mass can be divided into three granites; quartz monzonite, granodiorite and biotite granite, by petrological aspect in detail. 5) It shows inverse ratio of content between quartz and plagioclase. 6) The myrmekite-texture of the granite are stem type and dominating in northern part. 7) In the tectonic analysis of joint, the strikes are almost constant in direction, N-S direction of dominant joints 8) The geological age of the granites estimated to be Jurassic in age. 9) According to the mineralogical distribution and joint systen, the intrusion direction of the granite magma was infered as from north to south.

This model of earth science curriculum is developed paying attention to the cognitive stage according to child ages with the analysis of Piaget's cognitive domains, competency goals, and performance indicators. It is the function of the school to help children develope their cognitive abilities through their educational year. Elementary school teachers need to become aware Piaget's theory, particulary the preoperational, concrete, and formal levels so that they can diagnose thinking problems and respond more wisely to children. The unit of ocean should be emphasized especially because of Korea is surrounded with oceans, therefore ocean chapter has been developed in sixth grade according to the results of the questionaire. consequently earth science has to emphasized as domestic science rather than theoretical science has to emphasized as domestic science rather than theoretical science in elementary science education, with greater importance attached to the oceangraphy area in earth science.

In recent years, compression molding of lone fiber-reinforced thermoplastics has been increased in commercial aspects. In the process of compression molding of composites, the flow analysis must he developed in order to accurately predict the finished part properties as a function of the molding process parameters. In this model FRTP is assumed to be nonisothermal fluid, which has different viscosities in extensional and in shear. For verification of the model, the formation of a knit line in the L-shaped parts is compared with that of experiments results. In this paper we will discuss the effects of extensional & shears viscosity ratio ξ and slip parameter α on the other mold fill-ing parameters

Environmental education must develop students' habit of mind to preserve our environment through the Intel-nationalization of value about environmental preservation. The purpose of this study is to develop and administer simulation instruction in order to internalize the value of environment preservation and foster the habit of mind to preserve the environment. Two 6th-grade classes are randomly sampled from an elementary school located in Chongju-shi. One class is assigned to experimental group and the other to control group. Experimental group is exposed to simulation instruction, and control to traditional instruction. Pre- and post-test was administered to both groups. Pre- and Post test consist of three inventories; academic achievement on environment preservation, the awareness of environmental issues, and the level of internalization of values on environmental preservation. Teachers' instructional practice on environmental education was also investigated with a questionnaire developed by the researcher. The major findings of the study are as follows. Teachers reported the lack of instruction material, and teaching plan on environmental education. Teaching plan was developed based upon five step instructional model, problem identification, exploration, responding, revising, and advancement. Simulation activities are given in the final stage, advancement. The effects of simulation instruction are as follows. First, students showed changes from direct and sensory to perceptive responses though simulation instruction. Simulation instruction seems to enhance students thinking abilities on environmental issues, hence to help them exploring the solution to environmental problems. Second, The mean score of experimental group is higher than control group by 14.3% on the test of the level of internalization of values on environmental preservation. Third, the experimental group showed higher increase than control group in the score of academic achievement especially in the sub-domain of thinking skills. As a conclusion, the simulation instruction make students be placed in various roles, hence foster their judging abilities through value-conflict experience. Students perception on environmental issues changed positively, and their academic achievement was also increased.

In 1967, the science of education study group was organized by the science faculty members whom were prof. Kim, Sang-ok, prof. Kim, Young-dae, prof. Choi, Byung-mun, full time lecturer Cho, Seon-hyeong(joined in 1970), full time lecturer Moon, Chan-ho(joined in 1972), and prof. Park, Tae-woo at Dept. of Education at the Cheongju National Education College. The others were teacher Lee, Bu-young at the Attached Elementary school of Cheongju National Education College and Neil Woodruff, a United States Peace Corp member in 1970. They imported the Science Curriculum Improvement Study(SCIS, Berkeley team head Karplus, University of California, 1965) program materials which were textbooks, teachers guides, teaching materials and others in 1967. And then We translated the SCIS textbooks and the teacher's guides and the teaching materials manuals on korean language, and prepared or bought teaching materials for one class. The study group put the SCIS program materials into experiment classroom in attached primary school of Cheongju National Education College, step by step, from first to fifth grade which class were nether changed and nor mixed for 5 years from 1968 to 1972. In 2002 and now after 30 years have passed, the author studies the trace research according to students who learned in the SCIS science curriculum in primary school, but too many years passed to analyzed things at that time. The result of this study are as follows: First, SCIS Program showed no significant effect to improve students' learning achievement under the National Curriculum at the time. Second, the program showed significant effect on improving the ability of scientific thought and the formation of scientific concept which was supported by the previous researches. Third,, for the students who were experienced in the Program inspite of became middle school students, but in case of high school students decreased the students preference of science. Fourth, the efforts of SCIS Program in elementary school showed no significant effect of the students decision of their high school or university course. Fifth, the SCIS Program had an effect when the students who had formed the ability of scientific thought and the scientific concept, and experiencing in the Program learned middle school science. Sixth, the SCIS Program didn't have an influence on the decision of job and social life of the students' who had experienced the SCIS Program. It was showed the Third National Curriculum in Korea which had been effected by SCIS Program was a disparate curriculum on the problem solving of real life. Seventh, The students thought The SCIS Programs about 30 years ago are too many influence to social life and got jobs in these days.

The purpose of the research is to investigate the effects of a portfolio system on students' socio- psychological classroom environments in elementary science class. Two schools were selected from a metropolitan area, a city, and one school from a rural area in central Korea. Two fifth-grade classes were sampled from each school selected, and one class is assigned to experimental group and the other to control group, respectively, The total number of participants of the study is 399. Portfolio system was administered to experimental group, and conventional teaching to control group for two and half month. WIHIC, an inventory to measure socio-psychological classroom environment, was administered as a pre-and post-test. Experimental group gained statistically higher scores on WIHIC after administering portfolio system. They showed more positive perceptions on sub-areas of WIHIC such as teacher support, task orientation, and equity. There is interaction between region and group: the effects of the portfolio system is highest in rural area, lowest in metropolitan area, and the city in between. Portfolio system have positive effects on students' socio-psychological classroom environments. Enhanced socio-psychological classroom environments is expected to contribute to positive self-concept, higher science achievements, and self-directed learning.
