        초등학교 자연과 학습자료 준비를 위한 연구 : 초등학교 4 학년 자연과 중심으로 Based on the Natural Science for 4th Grade

        김해경,남철우,김정길,한광래,문두석 한국초등과학교육학회 1997 초등과학교육 Vol.16 No.1

        In this study, the teaching-learning materials in the natural science text book for 4th grade, written based on the 6th natural science curriculum, were analysed and classified with preparing method. The purpose of this study is to help science teachers ready for the teaching-learning materials, by providing the some information about the means and method of preparation and resources. As a results, the total number of these materials is 697 and the number of kinds is 246. And the number of kinds with preparing method is 50 for purchase(69.9%), 36 for gathering(14.6%), 18 for collecting(7.3%), 8 for manufacturing(3.2%), 4 for breeding-growing(1.6%) and 30 for others(12.2%) respectively. This study, furthermore, suggests the several substitution materials, and developed outdoor learning materials with relation to stratum and fossil as well as manufactured slide program showing various environmental pollution in Kwangju and Chunnam local area.

        초등학교에서 과학과 전담제의 실태와 적용 효과

        김정길,김석중,송판섭,한광래,최도성,문두석 한국초등과학교육학회 2005 초등과학교육 Vol.24 No.1

        This study is purposed to research the present status and outcomes of adaption of science teacher system in elementary school. The subjects of this study are science teachers, schoolmasters, science supervisors, and 3rd-6th grade students in western office of board of education, Gwangju Metropolitan city. It was found that there are 264 teachers who teach one subject and only two of them were science teachers. In elementary schools, most classroom teachers didn't want to be science teachers and schoolmasters or science supervisors could not afford to adapt science teacher system. After applying science teacher system to 3--6th grade students during one school year, many students were improved in academic achievement and inquiring ability, and they have increased of interest and participation in science activities. This means that science class by science teacher is more effective than that by classroom teacher. Therefore, science teacher system should enlarge to science class in elementary school.

        The purpose of this study is to guide and apply gettable and accessible materials around everyday life into classroom instruction, and to find out their effects on student academic achievement. In order to achieve it, this study was tried to develop and guide available materials around life in learning activities, to provide a preliminary assignment that could apply the available materials, and to compare its academic achievement to one from field trip learning. For the hypothesis testing, first, the experimental and comparing classes were selected based on the results of basic learning diagnostic evaluation, which conducted by the researcher being served as a full-time science teacher of the third and sixth grade of K elementary school in Kwangju for 2 years. Secondly, the instructional use of the available materials around life was applied to the experimental class. Also, the instructional use of the existing materials was applied to the comparing class. Finally, for the testing of the effects on academic achievement, the posterio test was implemented after conducting the experimental instruction in knowledge·understanding, inquiry process, and attitude domains classified by the unit characteristics. Using SPSS/WIN program the t-test was performed in order to compare the differences between the two groups. Major findings were as follows: 1) In the achievement test of knowledge·understanding domain, there were no significant differences at the 5% level between the experimental and comparing classes. It could be difficult to say, therefore, that the instructional use of the available materials around life was more effective than the instructional use of the existing materials. However, it had some effects on differences between the third grade final achievement test and sixth grade experimental class. 2) In the achievement test of inquiry process domain, there were some significant differences in that the sixth grade experimental class was higher than the third grade out-of classroom experience unit. It was indicated that the instructional use of the available materials around life had some effects on improving the students` inquiry ability. 3) In achievement test of attitude domain, there were some significant differences. It was shown that the self-evaluation test of the sixth grade experimental class unit was higher than that of the third grade out-of classroom experience unit; Especially, the learning activities in the experimental class were more active, and the experimental practice ability was improved. It was presented that the instructional use of the available materials around life had some effects on the students` academic achievement in attitude domain. It was concluded from this study that the instructional use of the available materials around life was less effective on knowledge·understanding domain, but was effective on improving their scientific inquiry ability and interest on science education.
