The purpose of this study was to compare the ideas of pupils with that of the scientists about controlling and identifying of variables, in the two cases: open or guided inquiry. The subjects were the 7th grade boys and girls in a school, in Seoul, Korea. For the guided inquiry, the problems were given by the experiments of pupils' text. Pupils were asked to identify the variables in the experiments. For the open inquiry, pupils set their own inquiry problem. The pupils whose marks are within upper one-third of three classes were chosen. Pupils' ideas on variables were investigated in the design of experiment for their problems. In that, questionnaire developed by researchers was used. In the former, many of the pupils identify just only one variable despite of the fact there were two independent or dependent variables in the experiments. In the latter, the number of independent variables increased two or three. However, pupils do not control independent variables: they vary two independent variables simultaneously in the design of experiment. From these, we compared the pupils' ideas on variables with the scientists'

The purpose of this study was to grasp the characteristics of composition regarding the material-centered integrated unit of environmental and natural studies, a science subject in Finland, to investigate a need for applying the material-centered integrated unit to the science curriculum of Korea. For the purpose, the study made an analysis on contents, inquiry activities, and visual materials (the most important in the elementary science curriculum and textbook composition), and it brought following results: First, as a result of analyzing the area of contents, the bicycle material-centered integrated unit comprised a large proportion of 44 pages (25.3%) of the whole 174 pages from the environmental and natural studies textbook for the third grade. The contents included such various concepts as traffic rules, safety, environmental protection and pollution, recycling and separate collection, tubes and triangular structures, wedges and screws, leverage, wheels, axles, gears, elasticity (spring), friction, and so on. Second, as a result of analyzing contents related to the thinking ability of inquiry activities, "expecting or confirming expectations" and "application" are included in every lesson, and one lesson is composed in such a way that students can study on bicycles as a practical material for their daily life and they can improve various thinking abilities. Third, as a result of analyzing the circumstances of inquiry activities, daily circumstances made up eight lessons (80.0%) and technical and social circumstances made up two lessons (20.0%) by focusing on bicycles, a material related to students' daily life. Fourth, as a result of analyzing visual materials, the percentage of pictures and photos was high at 53.4% and 45.2% respectively. As a result of analyzing the role of visual materials, the percentage of the illustrative role and explanatory-complementary role was high at 52.1% and 47.9% respectively. Lastly, as a result of analyzing from the epistemological view to interpret the relation between visual materials and students and the position of visual materials, the visual textbook materials were provided toward a way that students can decrease their feeling of epistemological separation in the three fields of ideational metafunction, interpersonal metafunction, and textual metafunction.

This study analyzed the uses of visual representations of particles in the matter units of the middle school science textbooks developed under the 2015 Revised National Curriculum. The material units in four textbooks were divided into explanation, inquiry, and evaluation sections, and visual representations of particles presented in the science textbooks were analyzed by the use type, the activity type, and the level of activity. In the explanation section, the visual representations of particles were mainly presented in the auxiliary use type, and in the inquiry and evaluation section, they were mainly presented in a direct use type. In terms of the activity types of the direct use of visual representations of particles, the interpreting activity was mainly presented in the explanation and evaluation sections, while the generating activity and completing activity were presented in relatively higher proportion in the inquiry section than the other two sections. In terms of activity level, identifying was the most common activity level in the explanation section, and inferring was the most common activity level in the inquiry and evaluation sections. Based on these results, the implications for the presentation and uses of visual representations of particles in science textbooks are discussed.

The purpose of this study wasto analyze the factors that enhance their learning achievement in a fieldtrip environment. For this academic goal, we analyzed a pattern of fieldtrip-related perception and attitudes of 19 science-talented students who participated in the 2007 KESO winter school. As for the perception type, the result of analysis showed that the science-talented students understood a fieldtrip as an experimental inquiry from an inquiry perspective, and that their understanding about a fieldtrip was based on anthropocentrism, positivism and instrumentalism from a science philosophy perspective. Regarding theattitudes type, the result revealed that the purpose of the winter school was mainly to learn knowledge in earth science, and that there was a significant tendency for the participating students to become a future scientist more eagerly than their parents expected. Students' fieldtrip-related academic self-concept was mostly positive while the participants experienced both positive and negative emotions.

The purpose of this study is to analyze the safety contents presented in high school science textbooks of the 2015 revised national science curriculum. For these, we found safety contents in the inquiries and appendices of 63 science textbooks: integrated science, science inquiry experiment, physics I, II, chemistry I, II, biology I, II, and earth science I, II. We analyzed these safety contents using six safety factors based on the seven standards for safety education. The main results are as follows: First, 81(46.0%) inquiries among 176 curriculum inquiries contain safety contents, and these contents are mainly found in chemistry textbooks, and the least in 'science inquiry experiment' textbooks. Second, safety contents are found the most in 'laboratory safety rule', followed by 'safety symbol' and 'usage of protection equipment'. Third, the safety contents of appendices are mainly in 'laboratory safety rule' and 'accident treatment'. Based on these results of this study, it is concluded that these textbooks have problems; that there is a big difference in describing safety contents in each textbook; that these safety contents are not presented in detail and that the educational effect is reduced. Furthermore, the safety symbol is not standardized. We also discussed ways to improve the safety contents of science textbooks.

The Purpose of this study is to find the effects of the portfolio assessment on elementary students' scientific knowledge, inquiry process skill, scientific attitudes in the teaching of science. And finally the parents' response to the portfolio assessment is also investigated. In order to reach the goal of this study, the investigator developed the evaluation instrument such as an experimental report and a cumulative observation sheet for the 4th-grade Unit-1 'Light Propagation' and Unit-3 'Separating Mixtures', and then these were administered to 42 4th-grade elementary students in Inchon. Based upon the findings and within the limitations of this study, several conclusions can be drawn regarding the problems investigated. First, as the portfolio assessment offers enough information about individual student's performance, it has a highly positive effect on evaluating the students' scientific knowledges. It can also make possible to grasp the several aspects of the student's progress. Second, the portfolio assessment can be implemented without giving students any psychological pressure from testing itself. Therefore, the portfolio assessment is an effective means of appraising inquiry process skills. Third, the portfolio assessment is effective to evaluate the students' attitude toward science by means of individual records which include such aspects that is hardly found by the teacher who teaches science in the class. Fourth, as most parents showed a positive response to this portfolio assessment, it is considered to be effective method of appraising the result of teaching science at elementary school. Accordingly, this study demonstrated that the portfolio assessment is an effective method that can assess students' scientific knowledges, inquiry process skills, and scientific attitudes gained from science teaching-learning. Therefore, it is necessary to implement the portfolio assessment to other grade students as well in the following study where teacher may give more encouragements and suggestions to sti dents for the better learning motives. Also teachers should suggest more definite evaluation criteria to students so that they may improve the students' self and peer evaluation skills.

The purpose of this study was to develop an inquiry-based professional development program for in-service secondary science teachers and to investigate it's application. The inquiry-based professional development program was reconstructed based on SSCS problem-solving model, which is composed of 4 stages of search, solve, create, and share. The 28 science teachers' understanding of the SSCS program were investigated as implementing the program. As a result of this study, 8 SSCS modules have developed as the science teachers have searched, solved, created, and shared various situated problems. The science teachers found themselves to have positive perception of SSCS program. The SSCS program was effective in changing the learners' teaching/learning attitude and to develop individual scientific thinking. To make the SSCS problem solving successful and more effective, both science teachers' professionalism and pedagogical knowledge for selecting topic as the levels of learner should be considered.
