  • This study examined the content diversity of seven authorized science textbooks by comparing the characteristics of the science concept description and the contents of inquiry activities in the "weight of objects" unit. For each textbook, the flow of concept description content and the uniqueness of the concept description process were analyzed, and the number of nodes and links and words with high connections were determined using language network analysis. In addition, for the inquiry activities described in each textbook, the inquiry subject, inquiry type, science process skill, and uniqueness were investigated. Results showed that the authorized textbooks displayed no more diversity than expected in their scientific concept description method or their inquiry activity composition. The learning elements, inclusion of subconcepts, and central words were similar for each textbook. The comparison of inquiry activities showed similarities in their contents, inquiry types, and scientific process skills. Specifically, these textbooks did not introduce any research topics or experimental methods that were absent in previous textbooks. However, despite the fact that the authorized textbook system was developed based on the same curriculum, some efforts were made to make use of its strengths. Since the sequence of subconcepts to explain the core contents differed across textbooks, this explanation process was divided into several types, and although the contents of inquiry activities were the same, the materials for inquiry activities were shown differently for each textbook to improve and overcome the difficulties in the existing experiments. These findings necessitate the continuation of efforts to utilize the strengths of certified textbooks.

  • This study is to propose the possibility of narrative or story as a research methodology in the field of library and information science. To do this, I discuss the power and possibility of storytelling as a epistemological method of social science. Later, I look into turn to narrative in western scholarly traditions. And then, I introduced the process and the characteristic of the narrative inquiry as a subject and a methodology of research. I compare to another research methodology, ethnography and phenomenological research. At last, I reviewed the literature which is conducted by the methodology of narrative inquiry in the field of library and information science. I consider the possibility of adaptation of narrative inquiry in the field.

  • The present study was carried out to analyse the frequency(%) for five kinds of inquiry context elements for six kinds of the high school science textbooks in the 7th curriculum. All the elements was classified into three process achievement level such as the basic, supplementary and further level introduced firstly in the 7th curriculum. Five elements of the inquiry context categories appeared as pure scientific context(61.8%), everyday context(22.2%), natural environmental context(7.7%), techno-industrial context(5.9%), and social context(2.4%) in the basic, supplementary and further level. Social context wasn't appeared in the supplementary level. In five elements of inquiry context, total elements appeared 7,139(85.5%) kfrequencies in the basic level and 691(8.1%) frequencies in the further level. However total elements appeared 529(6.4%) frequencies in the supplementary level. The kinds and frequencies of the elements for the inquiry context suggested in the basic level were more than those in the supplementary and in the further level. The social context was not appeared in the supplementary level. However five inquiry context elements were all appeared in the basic and further level.

  • Inquiry approach in teaching science has been widespread in Korea since the Third National Curriculum in 1970's. But the effect of the approach has never been evaluated systematically in Korea, so the science educators do not know if the inquiry approach really works and if any critical problems inhibit the effect of the approach. In this context, the NAEP of the Unied States and the APU of the United Kingdom were model programs for assessing the effect of the inquiry approach in teaching science. The purpose of this study is to develop an assessment system for evaluating the effect of inquiry teaching in elementary and secandary schools. For this purpose, an assessment framework and 240 test items were developed and tried with a sample of 8,906 students. The results say that the developed tests are reliable. The average Cronbach $\alpha$ reliability coefficient of the tests was 0.69. The discrimination index(point-biserial correlation coefficient) ranged from 0.39 to 0.54 with a mean of 0.49, which indiate they are excellent in discriminating students in terms of their inquiry achievement. The test items were also analyzed by "item response theory." The results also say that the items are successfully developed.

  • The purpose of this study is to figure out gifted elementary science students' improvement in performing open inquiry after peer review. In this study, gifted fifth-grade students performed open inquiry and review of each other as peers after the inquiry. Students' inquiries were evaluated and the influences of the feedback from the peer reviews were analyzed in relation to the inquiry performances. As a result of this study, three key points were discovered: First, the evaluation score increased with frequent feedback or long discussions. On the other hand, with less feedback, the evaluation score didn't rise. Second, there were three types of improvement in inquiry related to peer review: No. 1 was improvement after feedback given by themselves. No. 2 was reflection of feedback given to other groups. As a last type, No. 3 was that the students learned from other groups' presentation without any feedback and improved their inquiry. Third, there were five kinds of giving feedback; (1) feedback understanding the inquiry correctly, (2) insufficiency of peer's inquiry without deep thought. (3) on the usefulness of the inquiry, (4) on the scientific and logic validity through critical thinking, and (5) how to develop the inquiry. In these kinds of feedback, the fourth kind of feedback (4) occurred most frequently but the fifth (5) occurred rarely. It means peer review helps students develop their critical thinking ability and teachers should encourage students to give peers feedback of the fifth kind.

  • This study investigated the effects of scientific inquiry experiments emphasizing social interaction on the academic achievement, the ability for science inquiry and the learning motivation of the students. To examine the differences among the classes of scientific inquiry experiments according to the way of organizing small groups, the effects of the group in homogeneous cognitive level and the group in heterogeneous cognitive level were compared. 255 7th-graders were grouped into the treatment group and the control group. After the treatment group received the scientific inquiry experimental lessons emphasizing social interaction and the control group received traditional lessons for one year, academic achievement, ability for scientific inquiry, and learning motivation were examined. These inquiry experiments were composed of four steps which are eliciting, familiarizing, constructing and bridging. And students can interact with peers and teachers through the process of relating observed phenomena to concept, constructing experiment procedure, and eliciting results. The ANCOVA results revealed that there were significant effects of science inquiry experiments emphasizing social interaction on the academic achievement, the ability for scientific inquiry and the learning motivation of the students. The significant academic achievement of the students in most of the cognitive levels, if not all, was found and degree of improvement in the ability for scientific inquiry was lower than that in the academic achievement. Concerning the effects according to the way of organizing small groups, there were significant improvement in academic achievement and learning motivation of the group in homogeneous cognitive level compared to the group in heterogeneous cognitive level. These results indicate that social interaction in learning is important and it has positive influences on the improvement in academic achievement and ability for scientific inquiry of students.

  • The study aims to investigate self-regulated learning ability (SRLA) of students and analyze its relationship to their science inquiry skill and affective domain of science in middle schools in Korea. For this end, the research questions include the followings: First, what level is SRLA of middle school students? Second, how does the relationship between SRLA and science inquiry skill look like? Third, how does the relationship between SRLA and affective domain of science look like? A research method employed in the study is the survey utilizing three questionnaires: a) a questionnaire of SRLA (Jung et al., 2004); b) a questionnaire of problem finding ability of the science inquiry skill (Jung et al., 2004); and c) a questionnaire of science affective domain (Seo et al., 2008, adopted from 2006 PISA Student Questionnaire). Responses to three questionnaires by 704 students from seven middle schools in Busan, Ulsan, and Gyeongnam in Korea were analyzed. The research findings were as follows: First, mean average scores of SRLA is 3.02 (${\pm}0.63$) in 5 Likert scale (1 = strongly disagree; 5 = strongly agree). Second, students with higher scores in science inquiry skill showed significantly (p<.05) higher scores in SRLA than others. Third, boys scored higher on self-efficacy scale than girls. As students advance their grade level, their affective domain levels of science significantly (p=.048) decreases, in particular, their self-efficacy level most significantly (p=.002) decreases. Fourth, SRLA was significantly (p=.000) correlated with science inquiry skill and affective domain of science. In conclusions, it appeared that the higher SRLA level of students in middle schools is, the higher level of science inquiry skill and affective domain of science is.
