The energy crisis has heightened our concern about the economic development. Perturbation in our supply and increasing prices of fossil fuels had created an greatest problem. It demands that the science teacher can serve as dispenser of information and techniques concerned with human life and energy. This article illustrates contents of the written teaching material concerned with the education, which is prepared for the senior high school students, to introduce comprehensive framework of energy conservation. The contents of the material consist of the following three items. 1. What are the preblems in energy consumption and supply? 2. How can we develop the new energy sources? 3. How can we save the energy consumption? Each item illustrated the statistical data, graphs, leading questions and problems for computing. The material also illustrates the laboratories concerned with saving electric power, utilizing the sun light, controling house heating and cooling system. Application of the material was carried out in two class of eleventh grade students, for on month period after class room. Since the period was too short the students had some difficulties to understand the principles of new energy production. They also showed a little difficulty in handling the exprimental equipment and analizing data. They were, however, much interested in the activities of the material.

In this study we investigated problems in the development of high school new sciencen education curricula and tried to find out how to improve them. We collected data from 60 science teachers and 300 students at 60 high schools in Kyungsang-pookdo, and 122 teachers attending the In-Service Training Institute at Teacher's College, Kyungpook University. The results of the investigation are as follows. Students strongly hope the science learning to be an inqury learning, but teachers and school administrators, however, are still sticking to the cramming system under plea of the lack of facilities and equipment or preparations for entrance examinations. This cramming system causes students' poor abilities of scientific thinking and little willing to learn science. The more remote is the place, the poorer is science teacher's ability. Many teachers in rural districts are not familiar with the new trend in science education that they can hardly direct an inquiry learning even if they were provided with facilities and equipment. The status of facilities and equipment gets worse in proportion to the remoteness of the location of school. Junior high schools in urban districts meet about 50% of the needs while those in the rural districts meet some 30%. The case is worse with senior high schools; senior high schools in urban districts meet only 30%. The case is worse with senior high schools; senior high schools in urban districts meet only 30%. As to labratories, almost schools in urban districts have a laboratory but more than half of them are hardly available because of poor facilities. Small schools in the rural districts don't even have laboratories at all. Science teachers are overloaded with 11 hours work a day not counting the hours spent on individual guidance of average sixty students per class, that is four hours ordinary lecture, two hours so called extra lecture, two hours general business, and two and half hours lecture preparation. The cost of materials for the junior high school laboratory work requires 330,000 won per class (15 groups of four students system), but the sum collected from the students in a class amounts only to some 60,000 won. With these data, following matters are discussed: ⑴ The minimum requirment of facilities and equipemtn, ⑵ the cost of materials for junior high school laboratory work, ⑶ the teaching methods of inquiry learnning, ⑷ the loads of science teacher, and ⑸ the systems of science teacher training courses. From above studies, we suggested that: ⑴ An intensive investment should be made for the complement of science education facilities and equipement, not by parent but the authorities, ⑵ The cramming teaching must be changed and such learning methods must be encouraged as will let students inquire voluntarily into nature and feel the joy of discoverly. ⑶ Pre-service and in-service training must be reinforced for the science teachers to cultivate their research abilities. A prefessional science supervisor system and an autonomic local training institute system must be established. ⑷ Science teachers must get rid of overload, and a laboratory assistance must be employed per one laboratory, ⑸ The student's fees of laboratory work must be raised up, and students must be given enough opportunities to work with laboratory. ⑹ Instead of giving extra lecture, schools and teachers must provide to their students enough opportunities to work with their own interested things in science, especially those students who live in agricultural or fishing villages must be given the opportunities to learn about prac- tical problems connected directly with their lives.

C.G.C平面廻折格子에 依한 水素 Spectrum의 測定

Spectral analysis may be one of the most useful ways of introducing the basic concepts of modern science, and some short of research work in secondary school science education. It is, however, not easy to obtain a sufficient accuracy with a popular spectrometer alone. Some short of complementary equipment may be needed for these analysis. The purpose of this paper is to show what accuracy will be obtained when the C, G, C plane grating is utilized with a popular spectrometer. The wavelength of Balmer Series of Hydrogen spectrum Hα, Hβ, Hγ and Hδ were measured with the spectrometer Gaertner 35AW type and the C, G, C Grating 25,000 lines per inch. The Gratng Constant d was calculated by measuring the known lines of mercury discharge spectrum. The Rydberg Constant and the ionization potential of Hydrogen atom were calculated from the measured wavelength. The difference between observed value and theoritical value of Rydberg Constant was about 0.001%, and the difference of the ionization potential was about 0.002%.

國民의 科學化 運動과 科學敎育

For the movement of the modernization of daily life, it demands reformation of the citizen's sense of value, and further cultivation of their scientific ability, especially scientific thinking ability. Since the students will be the future volunteers of this movement, they need to understand way of scientific life, and to acquire more abilities of doing science. It is requested that science curriculums include more practical contents related to the student's daily life, such as energy crisis, food problems, and pollution prevention, because these problems are impending and urgent to the society as well as to the life of the students. The teaching methods should be improved toward individualized instructional approach, and enough opportunities for them to investigate real problems arising in the student's daily life should be given to the students because such a teaching method whould be more effective in obtaining scientific abilities, and in understanding value of science. The laboratories of the schools should be open to the students and the citizens, which will function, as a center of the movement so that the teachers help them to solve their problems scientifically There are, however, several difficulties remained in teaching science by means of these teaching methods, such as insufficency of facilities and equipment, heavy teaching loads, and heterogenity of intellectual levels in the large class size. So it also demands the increase of the government budget of science education to solve these difficulties. It seems, however, more important to create the climate of doing science in the life of students as well as citizens.

崔宗洛,朴德圭 경북대학교 교육대학원 1976 논문집 Vol.6-7 No.-

One-, two-, and three-dimensional optical crystals were constructed with diffraction plates made by photographic reduction. Their structures have been analysed by using a low-power laser beam. Form and structure of lattice points were investigated from one-dimensional optical crystals, and lattice constants were measured and calculated from two-dimensional optical crystals. Orientations of lattice planes in three-dimensional optical crystals were also investigated. The values of above all were in good agreement measured ones with their actual ones. Optical crystals enable one to use effectively as teaching materials for analysing crystal structures at all university levels in both classroom and laboratory.

Recently experimental scientific problem solving skills and scientific attitude have been emphasized on the science education. The method of evaluation of the skill and the attitude, however, has not been much introduces to the science teachers. In this paper the domains, the objectives and the methods of evaluation of physics in high school were discussed related with Piagetian formal operational pattern. The objectives of knowledge and comprehension were divided into six parts according to the Piagetian logical thinking pattern. The objectives of the problem solving skills however were divided into twenty parts. Related with the scientific attitues, the cognitive (analytical and empirical), the value (judgement, commending) and the attitude (emotional response, personal likes) were also discussed in this paper.

The emphasis given to experimental problem-solving skills in the physics curriculum innovation has not been matched by the development of the evaluation istruments. The purpose of this study is to develope the instrument for high school physics teaching. The instrument consists of twenty-two pencil-paper test problems of the unit, "force and motion", in the textbook physics I. These problems are related to integrated process skills and logical thinking ability, and they are classified by means of Piagentian type of logic patterns. The instrument was applied to three high school senior classes. Two hundred ninety five students in total participated in this test. The results of the application showed a considerably good relationship between the score of the test and the intelligence quotient (r=0.7). The reasoning ability was, however, very poor.
