  • The purpose of this study was to understand characteristics of eighth graders' conclusions presented in their self-directed scientific inquiry reports. We developed a framework, Analysis of Conclusions of Self-Directed Scientific Inquiry, to analyze students' conclusions. We then compared the conclusions with the inquiry questions students generated to find out whether the questions affected students' conclusions. In addition, we analyzed students' responses from the survey about their perceptions of drawing conclusions. According to the results, the conclusions were characterized into two categories, i.e., scientific basic assumption and scientific explanation. Almost half of the students' conclusions fall under the scientific basic assumptions. Most of the scientific explanations were deductive explanations and inductive explanations. Then, the kinds of conclusions were affected by the inquiry questions because the scientific explanations were made more than the scientific basic assumptions in answering the inquiry questions. Some students couldn't recognize differences between conclusions and experiment results.

  • The purpose of this study was to investigate the effect of specialized thematic science club activities on the students' scientific attitudes. The subjects of this study were ninety students from two high schools in Korea. The study group consisted of forty experimental groups and forty six science clubs with no special topics. The mean, standard deviation, t-value, and significance were compared with the corresponding sample t-test. First, specialized thematic science club activities showed positive effects on students' scientific attitude. Although the average scores of the scientific attitudes of the experiment group and the control group were improved before the operation of the club, the increase of the experimental group which operated the specialized topic was larger than that of the control group and there was a statistically significant difference. In the analysis of sub-elements of scientific attitude, the increase of the experimental group was larger than that of the control group. There were no statistically significant results in the control group, but the experimental group showed significant differences in openness, creativity, and cooperativeness among the subordinate factors of scientific attitude. Second, to investigate the effects of the specialized thematic science club activities on the scientific attitude in school, family, and social situations solving the problems of daily life as well as solving the science problems, there was no significant difference within the group, but there was a statistically significant difference between the experimental group with the specialized topic and the home and school situation. This result indicated that the scientific attitudes required to solve problems in the home and school have improved positively.

  • The purposes of this study were to analyze high school students' understanding about the Earth system and systems thinking process, and to develop science writing programs designed to assess students' understanding about themes of Earth Science such as global warming, volcanoes, and desertification. A total of 8 $11^{th}$ grade students from general high schools participated in the writing program and draw the causal maps. The methods of this study are as follows. First, DAET-C was used to investigate the way of students' understanding about the Earth systems. What the students' best understood was the component of the Earth systems followed by the interaction of the Earth systems and the scientific literacy of Earth science. Second, feedback circulations on the causal maps were found in four students in global warming section, one student in volcanic eruption section, and four students in desertification section, which means that systems thinking was not largely employed by the students. Consequently, the student participants understood that the global change was happening in correlation with complex concepts and factors, but they were short of using systems thinking in their science study. Therefore, the result of this study suggests that more studies be conducted to develop systems thinking in Earth Science learning through science writing programs.

  • The purpose of this study is to investigate the effect of science writing heuristic class on 'seasonal change' on elementary school students' science learning motivation and scientific attitude. In order to carry out this study, 49 students from 6 grade of elementary school in P metropolitan city were selected and 24 students in one class were selected as experimental group and 25 students in the other class were selected as the comparative group. The experimental group was taught science writing heuristic in 10 times classes related to the 'seasonal change' and the general classes related to the 'seasonal change' were conducted in the comparative group. Based on the results of this study, the conclusions are as follows. First, the science writing heuristic class about 'seasonal change' showed a significant effect on elementary school students' science learning motivation for science class. This is analyzed as a result of the students being more familiar with their science class through science writing heuristic class. Second, the science writing heuristic class about 'seasonal changes' showed a significant effect on elementary school students' scientific attitude. This is because the science writing heuristic class offered elementary school students an opportunity to combine their experiences in daily life with the contents of the class. Third, students' participation, satisfaction, and interest in the science writing heuristic class applied in this study were high. Therefore, it seems to be effective if the science writing heuristic class is used for science class for elementary school students.

  • The name of (Ban)wolseong thanks to its having a shape like a half-moon. Wolseong fortress is one of 'Gyeongju Historic Area', world heritage. The Silla kingdom's royal palace previously maintained its capital fortress at the locale of Wolseong. However its real face has been kept in mystery. This study grafts Geophysics on modern Archaeology and approaches with scientific and systematic methods to an excavation plan or archaeological study by means of GPR exploration which can complement archaeological curiosity without destroying Wolseong fortress. The exploration area is $12,000m^2$ in front of Seokbinggo(stone storage for ice). It is only $10\%$ area of Wolseong fortress. As a conclusion, GPR detected 7 of squared buildings($8{\times}8m^2$ size), stone wall, an entrance for the fortress, lots of foundation stones, road(presumptive), and a presumptive pond which size is 35${\~}$40m in diameter.

  • This study is an investigation regarding the understanding of the nature of science among pre-service science teachers majoring in science education. We interviewed 22 senior students in science education who finished their internship courses. Students were interviewed individually for approximately 20 minutes each. Data from semi-structured interview were audio-recorded and transcribed for the analysis. Findings indicated that participants held more complete understanding of the nature of scientific knowledge than the nature of scientific enterprise. Their understandings of the nature of scientific method was that hypothetical-deductive method is more scientific than descriptive-narrative method and there is a single stepwise scientific method to solve problems. These results showed that they have a narrow view of the nature of science. Thus, teacher education programs need to integrate the understanding of the nature of science throughout.
