  • Argumentative discussion is one of the important components of an educational program, which allows students not only to learn the process of social negotiation through discussions, but also to improve students' overall research abilities. The purpose of this study was to examine a) the changes between inquiry of before-argumentative discussion and inquiry of after-argumentative discussion, and b) the connections between the inquiry changes and online argumentative discussion. This study analysed 726 messages in an online argumentative discussion, as well as in first research reports and second research reports. The results of the study indicate that science-gifted students' research abilities were improved through on-line argumentative discussion that provided them with feedback based on interactive discussions, and encouraged them to re-examine hypotheses and experiment processes. The science-gifted students showed knowledge and abilities for identifying simple errors in research processes and arguing problems in the flow of the whole logic of research.

  • 지구과학 탐구 대상은 다른 학문의 탐구 대상과 달리 거대한 시 공간적 규모, 접근 불가능성, 통제 불가능성, 복잡성 등을 지니고 있다. 그렇기 때문에 지구과학의 탐구 대상을 실험실 내에서 실제 조작을 통해 탐구하는 것은 매우 어렵거나 심지어 불가능하다. 따라서 지구과학에서는 실제 조작을 하지 않고도 탐구를 할 수 있는 대안이 필요하다. 실제 조작을 하지 않고 탐구를 수행하는 대표적인 탐구인 사고실험으로부터 추론의 역할을 재조명하고 추론을 사용한기존의 탐구 수업 모형들의 특징을 조사하였다. 각 탐구 모형들을 지구과학에 적용하는데 있어서의 시사점을 살펴보고 이들을 바탕으로 지구과학적 현상의 탐구에 적합한 추론 중심 탐구수업 모형을 제안한다.

  • The purposes of the 'Students' Science Inquiry Experiment Tournament' which is one of the 'Students' Science Inquiry Olympic Tournaments' are; 1) cultivate students' intellectual interests, inquiry abilities, and scientific attitude dealing with students' scientific reasoning abilities, problem solving abilities, and experimental apparatuses operation abilities. 2) contribute substantiality of science education through experimental inquiry learning. 3) make the ground of basic science development of the future society by selecting excellent students who have talents for science. 4) elevate science teachers' morale by this tournament. The test items set and evaluation results of the tournament were analysed in this study. The results of this study were ; 1) the discrimination ability of the paper-and pencils test and the experiments were low because the students' scores of the items were not normally distributed and standard deviations were very small values. 2) most of the tournament participation students did not answered to the subjective type test items. 3) according to the responses of the tournament participation students, the tournament contribute to the students' interests in science. But the opinion was dominant that the tournament didn't contribute to school science education improvement.

  • This study examined the instructional influences of MBL programs on elementary school students' science achievement, scientific inquiry skills, and science learning motivation. The perceptions of students and their teacher toward science classes using MBL programs were also examined. The subject of this study was sixty four 4th grade students from two classes. The experimental group engaged in science classes that applied MBL and the control group engaged in traditional science classes based on the textbook and experiment workbook. As results, there was no significant difference in academic achievement, scientific inquiry skills, however, were significantly higher for the experiment group compared to the control group. There was also significant difference in the relevance and confidence, the sub-categories of science learning motivation. In the analyses of students' perceptions toward science classes using MBL, students showed positive perceptions in aspects of interests of science classes, content comprehension, and convenience of experiments. The teacher also showed positive perceptions using MBL in elementary science classes. Educational implications of appling MBL in elementary science classes were discussed.

  • Students' argumentation during science inquiry should be regarded important as it could help students to make meaningful connections between theories and experiments and to make scientific claims based on evidences. In this study, elementary science-gifted students' argumentation during small group inquiry was analyzed according to inquiry process. There were three stages of argumentation during students' inquiry. The first argumentation was to predict what would happen(Prediction stage). In this stage, the scientific problem was presented by concept cartoon as a way to start and to facilitate students' argumentation. The second argumentation was to design an experiment to solve the problem(Planning stage) and the third was to interpret the result of experiment(Interpretation stage). The discourse move, level of grounds and their relationship were analyzed to find the characteristics of argumentation during science inquiry. In terms of discourse move, 'Asking for opinion' was the most frequent whereas 'Claim' or 'Rebuttal' were rare. Students tended to listen to or ask others' opinion rather than provide their own claims or critics on others' opinion. 'Rebuttal' was shown a few times only during prediction and planning stage. There was no single 'Rebuttal' during interpretation stage. Students tended to easily accept or agree other student's interpretation of data instead of arguing their own ideas. In terms of level of grounds, students mostly provided their ideas without any attempt to justify their position. Especially during planning stage, students tended to suggest or decide ways of measuring or controlling variables without any grounds. They used evidences only a few times during prediction stage. In terms of relation between discourse move and level of grounds, students provided grounds most frequently when they dispute others' claims. The level of grounds were higher when they advocate or clarify their own or others' ideas than when they claim their ideas. The result of this study showed that the quality of elementary science-gifted students' argumentation during science inquiry was undesirable in many ways. Implications for scaffolding and facilitating argumentation during science inquiry were discussed.

  • The purpose of this study was to investigate science related attitudes, scientific knowledge, and scientific inquiry skills of middle school students when HASA(3H-hand, head, heart-at Science Activity) programs were applied to them. The HASA program is a program developed as an alternative to the current educational system. There are some basic principles for developing this program; it should be fun or of interest to students; it should be a manual activity that students can do with their own hands; it should be found in everyday life; and it's final goal is to improve scientific attitudes. The learning program consists of a series of 10 activities (10 periods). One hundred and sixty-two middle school students (7th graders) participated in the study and were divided into three groups. The HASA group (N=58) was exposed to the HASA program and the Lecture group (N=59) was exposed to the expository method of learning scientific knowledge, and the Lab group (N=45) was exposed to the experiment through textbooks. The results were as follows: 1) the HASA group was marginally higher than others but with no significant difference in science related attitudes; 2) the Lecture group had a significantly greater level of achievement in science knowledge; 3) There was no difference in the improvement of scientific inquiry skills.

  • 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.
