Inquiry has great value in environmental education(EE). Being able to see the world environmentally through 'inquiry-based environmental education' can be an important value and goal of EE. In this study, we intended to develop an EE program of measuring activity of dissolved oxygen(DO), based on the theory of 'inquiry-based EE'. Especially, we recognized the potential that DO meter can be used in 'inquiry-based EE', and we tried to develop a model of inquiry-based EE using DO meter. As a result of this research, we present specific models of inquiry-based EE about how to perform measuring activity of DO and how to use the DO meter in laboratories and streams from the perspective of inquiry of water environment. In the process of program development, we considered organization of the inquiry process, use of concept and knowledge, scientific inquiry and insightful inquiry, integration, sustain-ability, content components of 'Environmental Studies for EE', developmental level and in-forest of students. The developed EE model is a scientific inquiry model, pursuing 'explanation' based on data collection. Through this model, we tried to make students see water environment more deeply. The developed program can be applied to various water environments, like laboratories, streams, ponds, etc. It can be more effective inquiry activity if we perform measuring activities simultaneously with PH, electrical conductivity, and turbidity meters.

The scientific inquiry enterprise consists of formulating hypotheses, testing hypotheses, evaluating evidence, and revising hypothesis. Scientific inquiry in the science classrooms requires students' background experience and knowledge with the phenomenon in order to ask appropriate questions, identify and define variables operationally, formulate hypotheses, and design clear and complete experiment. The ability to test hypotheses has been postulated to play a central role in cognitive processes. The purpose of this study was to analyze what the change of the quantity and quality of the hypothesis, the rejecting or accepting of the hypothesis, and the use results in the repetitional hypothesis activity experiments. To examine the problems, this study analyzed 5 classes which were designed and administered to 16 students of the 7th grade. The results of this study showed that students preferred the engineering method to scientific method and the quality of a second hypothesis got low. The quality of the hypothesis came to be higher through a repetitional hypothesis and the number of hypothesis was reduced. The results of the experiments did not play central roles in revising hypotheses and accepting or rejecting hypothesis.

The purpose of this study is to investigate the effect of STEAM program on students' academic achievement, creative problem-solving ability, scientific inquiry ability and scientific interests of elementary school students. For this, we developed a STEAM program to utilize animation production about 'structure and function of the our body' unit in 5th grade. The STEAM program was developed for a total of 9 sessions and was applied to the experimental group. The theoretical lesson of the 2009 revised curriculum was consisted of 11 sessions and was applied to the comparative group. The results of study showed significant differences of the students' academic achievement, creative problem-solving ability to the experimental group participating in the STEAM program and also showed significant effects in the domains of subject contents and teacher preference, which are the areas of scientific interests compared to the comparative group. This means that the STEAM program to utilize animation production about 'structure and function of the our body' developed in consideration of the characteristics of elementary students positively influenced the academic achievement, creative problem-solving ability and scientific interests of elementary school students. In the future we need to develop STEAM programs more variously that utilize animation production and that it needs to be applied to elementary schools.

This study was accomplished to survey of current situation and management of science education in the special classroom(school) managed by firm. The status of management and the evalution of the scientific inquiry ability were taken on workers attending 17 Special Classes and 9 Special Schools located in Taegu City and Kyungpuk Province. As a responses, most students chose the subject "Science"as an option within their limited 8 units credits. About 88.5% of the students were female. About 78.3% of the classes/schools were conducted in the evening only. About 59.4% of teaching staffs were prevailed with female in these classes, and most of them were young, naive, and unexperienced with their major in chemistry and physics. Insufficient facilities and equipments, crowded classes, understaffed instructors, and inappropriated text materials. etc., were reasons for the students not receiving maximum benefit from these classes and schools. In order to evaluate of scientific inquiry ability, 25 items were constructed and administered to 250 students. The processes of scientific inquiry were classified into 5 categories(category I : establishing a subjects, category II : planning a experiments, category III : conducting a experiments. category IV : interpreting a result of experiments, category V : formulating generalization). As the result obtained from the achivement test analysis, the scores for all the students were significantly low, and the scores for girls were higher than those for boys. The results of test in the selected students showed that inquiry abilities in the category I, II and V were higher than those in category III and IV.

The purpose of this study is to develope and analyze a test for the assessment of physics inquiry experiment. To do this, three experiments about 'analysis of motion', 'the relation of force and acceleration', and 'free fall motion' in high school physics textbooks were chosen, and 5 scientific inquiry domains and 16 science process skills have been specified. For each experiments, test sheet of $29{\sim}44$ questions for assessing students' ability about physics inquiry experiment were developed on the basis of the scientific inquiry processes developed earlier. After instruction about 3 experiments mentioned above, a test was administered to the students who took experiment. After the adminstration of a test, the ratio of correct answers, discrimination index, and reliability were analyzed. Using the ratio of correct answers, we can determine item difficulty. Through the D.I(discrimination index), we can find which items can discriminate the students who took experiment well from those who took experiment badly, and we can also find the stability of a test result by the reliability analysis. The test developed in this study were also administered to the students who did not take experiments, and the results were compared with the those of the students who took experiments. With the comparison by chi-square method, we could find which items can discriminate the students who took experiments from those who did not take experiments.

In this study, a problem-centered learning based STEAM field experience learning program was developed and the effects of applying it were investigated. The program was composed of 8 sessions by using problem-centered learning education method and integrating STEAM elements between disciplines. The contents of program are as follow. In the step of sharing problems and making a problem-solving plan, they understood the various examples and meanings of endangered species, explored the project activities, and made an inquiry plan. In the search and re-exploration phase, a smart device was used to investigate the appearance, habitat environment and cause of extinction for Clithon retropictus, and a site inquiry plan was established for each group. Then, they moved to the field to explore brackish-headed gallops and discuss ways to protect endangered species. In the step of creating a solution, a web-based report was produced as the final product using smart devices based on the results of the inquiry. In the presentation and evaluation stage, the produced web-based report was used to present each group, conduct mutual evaluation, and organize project activities. The developed program was applied to 6th grade 29 students enrolled in the J University Gifted Education Center. In order to find out the effectiveness of the program, tests of science process skill, creative problem-solving ability, and scientific attitude were conducted before and after of program learning, and the results were statistically analyzed by t-test. In addition, a STEAM program satisfaction test was conducted after project in order to find out the satisfaction of the class. As a result of application of the program, the results were significantly improved in openness, criticism, and creativity among the sub-factors of creative problem-solving ability and scientific attitude. Satisfaction with the STEAM program was also high, but no significant result was found in science process skill. Therefore, the program of this study could be influenced on improvement of creative problem-solving ability and scientific attitude of gifted students in elementary science.
