  • This study was performed to develop a model for mentorship education in the science education institute for the gifted. Existing mentorship education models were focused on R&E, which involved science high school students as research participants. For this purpose, a new model was proposed with comparatively definite stages and terms, and based on the theoretical background concerning science inquiry abilities and scientific creativities or the mentorship education in the science education institute for the gifted. Existing mentorship models for science-gifted students were analyzed and compared with the scientific inquiry process and science paper form. A science paper form consisting of four stages was selected. A new model was constructed consisting of six stages, and this model was modified to be made fit for application to students in the physics mentorship course at the science education institute for the gifted in K National University. Good points and improvable points of the model through the application were identified, and the model was modified accordingly. In conclusion, a new model was proposed as a mentorship model for science-gifted students. This model was constructed using the PREPARATION-INTRODUCTION-METHOD-RESULT-CONCLUSION-FINISH format.

  • The purposes of this study are to analyze the learning contents on the measurement of reaction rate which is introduced in the high school ‘science’ and ‘chemistry II’ textbooks, and to revise the experiment appropriate to the learning contents. We examined 11 kinds of ‘science’ textbooks, 8 kinds of ‘chemistry II’ textbooks and 11 kinds of teacher’s manuals used in Korea and additionally surveyed teachers’ opinions on this subject. Most of textbook and teacher’s manuals described that ‘the reaction rate generally decreases through the time’, teachers’ conception also agreed with it. But most of experimental activities in the textbooks were inadequate to explain the concept that the reaction rate generally decreases with time. We analyzed the reasons and revised the experimental condition to solve this disagreement between the description in textbooks and an experimental result. Then we compared improved experimental result and theoretical prediction data. The improved experiment in this study is expected to help to describe the conception of chemical reaction rate in the textbook more clearly.

  • The purpose of this study was to analyze the characteristic of the linguistic interaction according to leadership type of the leader in the scientific inquiry activity groups and examine how leadership factors affect the linguistic interaction within a group. In this investigation, leaders among 12 elementary school students were chosen by considering results of the leadership diagnosis that tested 3 leadership factors: vision and promotion, assignment responsibility, and decision-making. The members of the groups were organized according to scientific inquiry ability and academic achievement; the groups were assigned to perform scientific inquiry activities. The linguistic interaction was largely divided into the cognitive domain and the affective domain for analysis. According to the results, the frequency of linguistic interaction within a group sorted by leadership type is more influenced by the cognitive domain than the affective domain. The highest frequency of linguistic interaction appeared within the group that had vision and promotion type leader. Assumedly, the vision and confidence of the vision and promotion type leader produced such an outcome. While solving the assignments, linguistic interaction in all three groups had more cognitive domain than affected domain. Linguistic interaction in cognitive domain displayed only low level of linguistic interaction in relation to the experiment itself: high level of linguistic interaction barely occurred. In the case of affected domain, active participation appeared more frequently than maintaining the mood: Interactions related to restricting the group members actions to solve the assignment appeared more frequently than those for maintaining the mood.

  • In this study, reliabilities of holistic scoring method and analytic scoring method were analyzed in performance assessments of middle school students' science investigation activity. Reliabilities of 2, 3, and 4~7-level rubric ratings for analytic scoring methods were compared to figure out optimized numbers of rubric ratings. Two trained raters rated four activity sheets of 60 students by two rating methods and three kinds of rubric ratings. Internal consistency reliabilities of holistic scoring methods were higher than those of analytic scoring methods, while intrarater reliabilities of analytic scoring were higher than those of holistic scoring methods. Internal consistency reliabilities and intra-rater reliabilities of 3-level rubric rating showed similar patterns of 4~7-level rubric ratings. But students' discriminations, item difficulties and item-response curves showed that the 3-level rubric ratings was reliable. These results suggest that holistic scoring method could be adapted to increase internal consistency reliabilities with improvement in intra-rater reliabilities by rater's conferences. Also, the 3-level rubric rating would be enough for good reliability in case of adapting analytic scoring methods.

  • An assessment instrument dealing with secondary students' views on the nature of science was developed in this study. The features in aspects of the nature of science are generally accepted as characterizing the scientific enterprise and we have focused on are: 1) the purposes of the scientific enterprise, 2) the nature of scientific enquiry, 3) the nature and status of scientific knowledge, and 4) the nature and functioning of the scientific community. The questionnaire is made of three sections; that is, "Scientific Question", "Experiment", and "Belief". The Scientific Questions probe was designed to examine the ways in which learners mark out science as a particular domain, and particularly the types of questions that they think are open to scientific investigation. The Experiment probe was designed to throw light on the ways in which learners may think about theories and their relationship to evidence in a range of contexts. A related aim concerns the sorts of activities that learners consider to be experiments, and their reasons for this. The Belief probe was designed to see whether students are able to articulate the grounds for their acceptance of a proposition and, if they are, to explore the nature of these grounds. The reliability of the instrument developed in this study was found to be 0.86.

  • This study aims to understand the trends and characteristics of elementary science textbook research. For this purpose, among the papers published in science-related journals from 2001 to 2021, 156 studies related to elementary science textbooks were analyzed to examine the research trends on textbook analysis. The analysis criteria consisted of two major categories, 'outward feature' and 'topic.' The subcategories of 'outward feature' consist of 'year of publication,' 'target curriculum,' 'target grade,' 'science content area,' 'subject of study,' and 'publishing institution.' The sub-categories of 'topic' consist of 'comparison,' 'content,' 'illustration,' 'inquiry activity,' 'perception of textbooks,' and 'others.' As a result of the analysis on 'outer feature,' textbook-related research was conducted almost every year, and the research on the 2009 revised science curriculum, on the 3-6 grades, and on the whole field of science had the most. The science textbook researches were published not only in science education-related journals but also in other areas' journals. As a result of the analysis of the 'topic,' the number of papers was higher in the order of comparative research, content analysis, illustration, inquiry activities, and perception of textbooks. Implications for accredited textbook system of elementary science were discussed based on the analyses on the elementary science textbook research trends.

  • High school 'science' in the 2009 revised curriculum in Korea was developed for the purpose of enhancing students' scientific literacy needed for citizenship in a democratic society. For this analysis, 'science' includes a variety of scientific topics from the origin of the universe to the birth of life, and the relationship between technology and modern society. It aims to make students understand the process of scientific inquiry and foster interest and curiosity about science. On the other hand, interest has been studied as a psychological construct to affect academic achievement and career selection of students. In this study, the authors investigated students' interest in high school 'science' in view of the 2009 revised curriculum. To carry this out, a survey tool was developed according to previous research, with 997 high school students' responses analyzed with descriptive statistics and factor analysis. The result showed that the students' interest in high school 'science' in view of the 2009 revised curriculum can be interpreted into three dimensions such as motivation, activity, and topic, which has several sub-dimensions. Students' interest in motivation dimension was higher than in activity or topic dimension, while the average value was slightly higher than the middle value. They showed different distribution of interest by gender and job orientation, especially in activity and topic dimensions. From this study, the authors can infer the multi-dimensional property of students' interest in high school 'Science' and the different distribution of interest by dimensions.
