The purpose of this study was to examine the effect of Small-Scale Chemistry(SSC) lab program on the academic self-efficacy and the science-related affective domain of 11th grade science-majored students. For this study, a SSC lab program was developed on the basis of analyzing the textbook of high school chemistry I in the 7th curriculum, and the experimental group was received SSC experiment lessons(SSC group), and the comparison group was received traditional experiment lessons. After students were grouped high and low level according to the students' prior science achievement score, the differences between the two groups were investigated using 2-way ANCOVA. From the result of this study, we found that the SSC lab program was more effective than the traditional Large-Scale lab program based on the textbook in academic self-efficacy. And the scores of interest toward science-related careers and creativity for the SSC group, which are subcategories of science-related affective domain were significantly higher than those for the comparison group. In students' perceptions on the SSC lab program, majority of students thought that the SSC lab program was convenient, effective and interesting.

The purpose of this study is to analyze the problems of rock specimens used for science education in elementary schools and to provide improvements of them. For the study, 20 sets of rock specimens were randomly selected from the five elementary schools in K city of Gyeongbuk Province and they were photographed and investigated. Also three elementary school teachers with more than 5 years of scientific career were interviewed. As a result, the sets of rock specimens that reflected the elementary curriculum were only 10%. The sets of rock specimens had many problems as follows: they were purchased a long time ago (up to 30 years), information presented in the nameplate and documentation was errorneous, some of rock specimens were too small and they did not show typical characteristics for education. In addition, the purchase and verification procedures of rock specimens were often neglected. With lack of interest and knowledge of teachers and lack of information about rock specimens, it was difficult to purchase good rock specimens for education. To improve the situation, a set of rock specimens should be verified by experts and should reflect the contents of curriculum and textbooks thoroughly. A manual of rock specimens is provided for science education in elementary schools.

The 7th curriculum which was administered to high school science courses from 2002 asked for a revel specific curriculum. But those curriculums were not developed. The purpose of this research was to develop a level specific curriculum for high school science courses, apply it to high school science courses, and then investigate the effects of this curriculum through the change in attitude towards science and perception towards level specific curriculum. The results are as follows. 1) The two types of level specific curriculum for high school science course was developed. In the first type, the level specific curriculum instruction was conducted in the same class whereas, instruction was divided in the second one, according to the students' intellectual levels. 2) Result on the perception of the test showed that developed level specific curriculum was ineffective in changing the students' attitude towards science, even though they recognized the importance of the curriculum. This was because the students perceive science as a difficult and uninteresting subject.

Environmental education, effectively performed at school, is very important to solve the environmental problems. Moreover the survey for teacher's perception is essential. The purpose of the study was to investigate the perception of environmental problems of middle school teachers in Pusan. The survey was done twice in 2007 and 2012, and based on the time intervals, careers, and major of the teachers. 200 teachers were chosen in 2007 and 300 teachers in 2012. How many environmental problems occurred during this time period affected the 471 teachers' perception was investigated and analyzed. The results are as follows. First, the perception difference of environmental problems was meaningful between two time intervals (p<.01). Especially, the perception of modern environmental problems and carbon emission showed considerable increase in both science and non-science major teachers. This may be caused by the climate change and the severity of lifestyles of indiscriminate consumerism. Second, the perception difference of environmental problems by careers was also meaningful (p<.01). Overall, the perception was obvious on the aspects of modern environmental problems, carbon emission, destruction of ozone layers, nuclear wastes, environmental hormones, and red tides. Teachers, having more careers irrespective of their teaching subjects, showed higher perception on the seriousness of environmental pollution, the necessity of environmental conservation, and the importance of health. Third, the perception of environmental problems between science and non-science major teachers was meaningful (p<.01). Particularly, the perception in the broad environmental problems was distinctive between them.

The purpose of this study is to analyze high school chemistry curricula in Korea and China in order to identify possible implications for the improvement of the Korean curriculum. The school curricula of Korea and China had been developed by the Ministry of Education of both countries as national curricula. The 1996 Chinese high school chemistry curriculum, and the 7th Korean high school chemistry curriculum announced in 1997 were compared in respect to the characters, objectives, history, time allotment, structure, subject contents, and assessment plans. Based on the comparative analysis of the curricula, some of the ideas, which provide implications for the improvement of Korean chemistry curriculum, were identified. The identified ideas were elaborated to seek directions for the solutions of current problems in chemistry curriculum. such as common science subject. tentative implementation of curriculum, compulsory provision of chemistry, subjects in science course, enlargement of curriculum, and methods of assessment.

While the 7th national education curriculum is gradually proceeding, science education tries various teaching-learning method for integration in science education. The first purpose of this study is to investigate Earth Systems Education(ESE), which is approaching method to integrate science education, especially in its focus on planet Earth. Also, the second purpose is to know what the reactions of students are obtained after 'The Global Climate Game' in ESE active learning program is applied to the field. The results of this study are as follows; ESE is to propose the integrated approaching method of searching for natures and ESE teaching-learning method is to try to overcome fixed conventional teaching-learning method focus on the text book, and practical application of ESE teaching-learning method is that we can develope the student-emphasized instructional program through the discussional cooperation-teaming models, role-play instructional models. In this study, 'The Global Climate Game' found that was suitable of understanding about relating of atmosphere, hydrosphere, lithosphere and biosphere composing Earth System. Reaction of most students for ESE was showed a positive change of aspect affective region and ESE active learning program is more efficient to improve schoolwork achivement and students positive attitude toward science subject than conventional teaching-learning method. Thus if ESE active learning program is applied for a long time, the general positive attitude of students concerning science will be increased, and then the students is expected to extend the ability of application of science in their life.

This study was performed to analyze the secondary students' perceptions and self-efficacy of performance assessments in the science subject. The data was obtained from 236 middle school students and 222 high school students in seoul. The students had generally proper understanding about characteristics of performance assessment which include purposes of assessment and differences from other conventional achievement assessments. They responded that the performance assessments were not useful in their science learning and developing their potential abilities. They were not satisfied with reliability and validity of the performance assessments. The middle school students more positively responded than high school students regarding the reliability of the scoring system and the originality of the evaluating materials. The female students more positively thought than males about the reliability of assessment and the usefulness for learning science. The students' self-efficacy level of performance assessment were not low in comparison with another existing assessments. They had high level of self-efficacy in understanding of experimental procedures, and utilizing of experimental apparatuses, but had low level of self-efficacy in understanding purposes of experiments or issues of discussions, processing of experimental results, answering of problems in experimental discussions. The female students' self-efficacy of performance assessment were higher than male students'. There was statistically correlated with females' scores and their level of self-efficacy of performance assessment.

The research is aimed at investigating the development and application of high school biology classes utilizing discourse-typed inquiry learning program fitted with POE, and the corresponding effect on student's academic achievement and attitude toward science. 4 classes of 11th graders in a general high school located in Busan were selected as subjects. Biology I, 'Circulation' unit was lectured for 4 weeks (6 classes), and the experimental group underwent classes utilizing discourse-typed inquiry learning program fitted with POE. The control group was taught identical major learning contents, but based on the learning objectives and research activities provided by Biology I textbook. As a result of application, first, the discourse-typed inquiry learning program fitted with POE exhibited positive consequences of linking previously acquired knowledge and the new learning attained through experiments, as well as not only improving the students' problem solving capacity through diverging questions from the teachers to drive the students' higher-level contemplation, but also enhancing student academic achievement by assisting their logical thinking. Second, POE-fitted discourse-typed inquiry learning program rendered presupposing session of the experiment that resulted in drawing learners' attention in advance, and incited active participation in the learning process through solving the contradiction between what was actually observed and what was expected, which eventually proved to lay out positive impact on students' attitude toward science.

The purpose of this study is to develop a science field study area using Geumgang(Geum River), fossil origins and various geological resources in Youngdong area of Chungcheongbuk-do as educational resources; and utilize them to develop an education program to cultivate earth science and topophilia. The Youngdong sedimentary basin (Cretaceous period) has a well-developed outcrop along the Geumgang and it is therefore easy to find various geological structures, plant fossils, and dinosaur fossils. Also, it has a distinct sedimentary structure, such as mud cracks, ripple marks and cross-bedding. Science field study area(6 observation sites) were developed based on school curriculum, textbook analysis, and professional earth science education panel discussion to create a convergence education program. The result of validating the developed program showed that all the items were satisfactory ($CVR{\geq}0.88$) in the test categories. The science field study teaching-learning model was applied to actual classes. The evaluation result for class satisfaction was positive, scoring Rickert scale 4.18. The result of observation about the outdoor classroom process in the science field study area revealed that students were able to form a new image of the beautiful scenery of the Geumgang. Also, the students could gain a new understanding, concept and value of various geological objects (sandy beach, stepping-stones, dinosaur footprint fossils, sedimentary formation), which naturally allowed them to form topophilia.

This study is intended to reconsider the meaning of the education for gifted/talented children, the foundation object of science high school by examining the behavior characteristics between gifted students and talented students in open-end mathematical problem solving and to provide the basis for realization of 'meaningful teaming' tailored to the learner's level, the essential of school education. For the study, 8 students (4 gifted students and 4 talented students) were selected out of the 1 st grade students in science high school through the distinction procedure of 3 steps and the behavior characteristics between these two groups were analyzed according to the basis established through the literature survey. As the results of this study, the following were founded. (1) It must be recognized that the constituent members of science high school were not the same excellent group and divided into the two groups, gifted students who showed excellence in overall field of mathematical behavior characteristics and talented students who had excellence in learning ability of mathematics. (2) The behavior characteristics between gifted students and talented students, members of science high school is understood and a curriculum of science high school must include a lesson for improving the creativity as the educational institutions for gifted/talented students, unlike general high school. Based on these results, it is necessary to try to find a support plan that it reduces the case which gifted students are generalized with common talented students by the same curriculum and induces the meaningful loaming to learners, the essential of school education.
