Chung, Young-Lan ; Lee, Joo-Youn ;
Journal of The Korean Association For Science Education, volume 24, issue 5, 2004, Pages 805~813
Our educational system clearly places much greater value on left hemisphere learning. Students who process information in other ways are at a serious disadvantage and may not be learning efficiently. Since mind mapping emphasizing visual and spatial language, it helps students to use the whole brain and promotes more effective comprehension. The purpose of this research was to determine the effects of the instruction using mind map on the science achievement of students. A pretest-posttest control group design was employed. Subjects were 153 male and female, first grade students in a middle school. A control group of 83 was instructed with a traditional teaching method, and an experimental group of 70 was instructed by using a mind mapping strategy. Two groups were treated for 50 hours during 17 weeks. Tolerance's 'Style Of Learning And Thinking(SOLAT)' was used to assess students' lateralization preferences. A 30-item multiple choice posttest was used to assess students' achievement. To analyze the data, we used an analysis of covariance(ANCOVA) and i-tests. It was found that 21.6% of students was left brain dominant, 31.4%, right brain dominant and 47.1 % was integrated style. There was no gender difference in hemispheric dominance. Significant differences existed between the test scores when they were taught by using a mind map. Mind mapping turned out to be a valuable learning technique for the right brain students, helping them to achieve the same level of subject mastery as left brain students. There was a significant difference between males and females in relation to mind map application. Female scored significantly higher than males.

Suh, Jung-Ah ; Jo, Kwang-Hee ; Song, Jin-Woong ; Pak, Sung-Jae ;
Journal of The Korean Association For Science Education, volume 24, issue 5, 2004, Pages 814~824
This article presents the effects of estimation activities related to speed and density on students' concept-understanding, answer-prediction, and answer-calculation in problem solving procedure with quantitative and qualitative methods. Participants were one hundred and ninety two seventh graders from one coeducational school in Seoul. Half of them participated in the estimation activities and the other half did in the measurement activities. Discussions of three students during estimation activities on density and their post-interviews were tape-recorded. Pre- and post-assessment scores were analyzed for the whole classes, and students' discussions and interviews served this research as evidences for the case analysis. Results of scores indicated that students in the estimation activities were significantly better than those in the measurement activities for predicting answers, but not for understanding concepts. Analysis of the cases revealed that estimation activity helped them to understand the relations of mass, volume and density, empirically, which enhanced their prediction ability. Furthermore, the ability could help a student with low calculation ability to comprehend the calculation problems. Thus, it is concluded that estimation activities could influence students' empirical learning on quantitative concepts, which enhanced their prediction ability.

Jeon, Kyung-Moon ; Park, Hyun-Ju ; Noh, Tae-Hee ;
Journal of The Korean Association For Science Education, volume 24, issue 5, 2004, Pages 825~832
In this study, the history of science (HOS) presented at the chapter of "Inquiry of science" in high school science textbooks developed under the 6th and 7th national curriculam was analyzed and compared. A total of 57 sections from 19 textbooks (6th: 12 textbooks, 7th: 7 textbooks) were analyzed in terms of the domain and the presentation level of the HOS described. The results revealed that the frequencies of HOS per page of the textbooks under the 7th curriculum tended to be higher than those under the 6th one in all the domains (conceptual, procedural, and contextual), of which the difference in conceptual domain was statistically different. Regarding the describing level (limited and extensive) at the presentation of the HOS, the frequencies of extensive descriptions per page for the textbooks under the 7th curriculum were also significantly higher than those under the 6th one. The improvement of frequencies and presentation level of HOS in 7th national curriculum could help students to understand scientific concept and nature of science and to have an interest about science.

Cho, Boo-Kyung ; Go, Young-Mi ;
Journal of The Korean Association For Science Education, volume 24, issue 5, 2004, Pages 833~842
The purpose of this study was to explore kindergarten students' attitude toward science by their gender and teachers' background. 90 kindergarten teachers and 180 5-year-old students were intentionally sampled in a suburban area. The research instruments used in this study were the interview questions of student attitude to science and the teacher's background questionnaire. The interview questions constructed by two researchers, based on "The Students' Attitude to Science Scale"(Pell & Farvis, 2001). It was composed of 13 questions; 7 questions on preference for science and 6 on perception to science. The teacher's background questionnaire was consisted of I question on educational background, I on career, and 51 on scientific literacy("Test of Basic Scientific Literacy")(Laugksch & Spargo, 1996). The results revealed that the students' attitude to science was positive and was different by their teachers' educational background, not by their gender and their teacher's career and scientific literacy. However, the students showed different preference for science by their teachers' scientific literacy. These results imply that early childhood teachers should have enough chances to be more educated and to improve their scientific literacy.

Noh, Tae-Hee ; Kim, Kyung-Sun ; Yoon, Seon-Ae ; Han, Jae-Young ;
Journal of The Korean Association For Science Education, volume 24, issue 5, 2004, Pages 843~850
This study investigated the effects of group processing in cooperative learning using task-oriented reward on students' science achievement, science learning motivation, and attitude toward science instruction. Eighth graders (N=58) selected from a middle school in Seoul, were randomly assigned to either the treatment or comparison group, and taught on the 'Separation of Mixture' over 8 class hours. The treatment group received cooperative learning using task-oriented reward containing group processing (GCL), while the comparison group received cooperative learning using task-oriented reward without group processing (CL). Significant interactions between the instruction and prior achievement level were found in the achievement and the attitude toward science instruction. High-level students in the GCL group performed better than those in the CL group, while low-level students in the CL group performed better than their counterparts.

The aim of this study is to acquire a better understanding of how natural history(NH) and natural history museums(NHM) are perceived among students, teachers and parents by administering a questionnaire. A total of over 2500 people participated in this survey. We developed the questionnaire which was categorized by three specific areas: 1) people's overall perceptions of natural history and natural history museums; 2)the way of people's getting such perceptions and knowledge; 3) people's possessing interests in NH and NHM. The summary of survey results included; firstly people had paid attention to nature and natural environments; secondly NH and NHM were not familiar to people, but they expressed their eagerness to learn about them; thirdly the first image occurred to people was dinosaur, when they recalled NH and NHM with describing them to be mysterious and education.; on the fourth, NH and NHM were informed through TV programs; lastly, most people responded that they never learned about NH and NHM in schools but they wanted to learn them.
The Changes of Preservice and Inservice Elementary School Teachers' Concepts of the Solar System Based upon Their Exposure to the Earth Motion Centric Solar System Model
Chae, Dong-Hyun ;
Journal of The Korean Association For Science Education, volume 24, issue 5, 2004, Pages 886~901
The purpose of this study was to document the changes in astronomical concepts for preservice and inservice elementary school teachers after being presented with the newly devised Earth Motions Centric Solar System Model. The subjects of the study were 31 preservice and 30 inservice elementary schools teachers in the Jeonbuk Province. First, the author investigated the naive theories of the subjects, and then, compared that data to the data obtained after their exposure to the model. The total number of items on the instrument for this study was 10. These items included questions about the motion of interior planets, the phases and sizes of interior planets, and the motion of exterior planets and comets. After analyzing the answers to the items before the experiment, the author was able to confirm the existence of the naive theories regarding astronomical phenomena. Also, after the experiment, the author was able to observe the conceptual change in thought of the preservice and inservice elementary school teachers. Results showed that learning through the new model had positive effects on the preservice and inservice elementary school teachers' conceptualization of the interior planets' motion, phases and sizes, and the exterior planets' motion.

Journal of The Korean Association For Science Education, volume 24, issue 5, 2004, Pages 902~915
Science drama can be an useful tool for understanding the nature of science, Science-Technology-Society relationship by providing indirect experiences to young students. Specific science concept and knowledge can also be learned with high interests. In this study, to explore the usefulness of science drama in elementary science lessons, two scripts of science drama and lesson plans were developed and implemented. Six step model for science drama lessons was also suggested. One was 'Manhattan Project' which dealt with social, ethical responsibility in using science & technology (science argument drama), and the other was 'Mom, My blood type is O' which explained the heredity of blood type (science concept drama). Two teachers were asked to write their journals during preparation and implementation of science drama lessons, and the lessons were observed by the researcher and video taped for analysis. Some students were interviewed just after the lessons by the teacher and all students were asked to write their impressions, change of their thought, what is leant etc. Overall responses of students and teachers on the two science drama lessons were very positive, 'Mom, My blood type is O' got more positive responses, and girls were more positive than boys. Some students anticipated another science drama even suggest topics for it. 'Mom, My blood type is O' was successful in making students (grade 3) understand the knowledge related with heredity of blood type (71% of the students got perfect answer). In 'Manhattan Project' students (grade 5) perceived more diverse location of responsibility after the lesson, but the danger and harmfulness of atomic power was embossed. This implied the need of more careful planning for the relevant learning activities before and after the play of science drama.Two teachers perceived the science drama as a new, useful tool for some subject which is hard to deal with by other teaching method. They were also satisfied with students' high interest and engagement during the science drama lessons but the extra time and effort for the lessons were pointed out as a main difficulties.

Lee, Myeong-Je ;
Journal of The Korean Association For Science Education, volume 24, issue 5, 2004, Pages 916~929
The purpose of this study is to investigate issues in science curriculum reform studies. For the study the papers in ERIC data base were selected on the key words, 'science education', 'curriculum' and 'reform'. The number of papers are the most on the late 90s which has been increasing since the late 70s. During the last decade the 132 papers were identified on 30 May 2003 and the 18 journals which have more than two articles in each journal have 66% of the total papers. The identified reform issues were 'reform themes', 'program introduction', 'critics and vision of reform'. Reform themes are 'teachers', 'scientific literacy', 'integration and teaching', 'reform processes'. The contents on 'teachers' are related to almost teachers' knowledges and beliefs on the reform, those on 'scientific literacy' are related to the loose definitions of scientific literacy, those on 'integration and teaching' are related to difficulties in teaching with integration, those on 'reform processes' are related to power problems between persons or groups who participated in reform processes, and those on 'critics and visions' are related to the embodiment of science education standards and the problems on the nature of science. This study remarks that these issues should be considered sincerely for the reform of science curriculum in the future.

Journal of The Korean Association For Science Education, volume 24, issue 5, 2004, Pages 930~936
Science field trip on historical heritages in Korea has developed since 1998. There are a few discussion of effectiveness of science field trip on historical heritages. In this research, the aim of science field trip on historical heritages was discussed in view of developing scientific perspectives on historical heritages with cases of science field trip of Hwasong fortress. Material for science field trip of Hwasong fortress was developed and instructional strategy was designed. The material contained convergent and divergent scientific inquiry activities. The goal of the activity was to help students to build scientific perspectives on the historical heritage, so they can evaluate the scientific excellency of historical heritage. The subjects were ten ninth grade students of middle school science club in Seoul. A questionnaire, "evaluation of scientific excellency of historical heritage" was administered before and after the field trip. From the analysis of a change in perspective by field trip, it was investigated how the scientific perspective on historical heritages was developed. The first draft of material for science field trip of Hwasong fortress was developed based on science education experts' discussion. The material has three parts; activities before the trip, activities during the trip and activities after trip. Instructor's guide has the same structure. Before the field trip, students watched the videotape and learned the short history lesson about Hwasong fortress to develop familiarity. During the trip, there were exploring stage and intensive inquiring stage. These activities were designed to develop scientific perspective on historical heritage. After the field trip, evaluation activity about scientific value of Hwasong was done based on the activities done during the trip. After the science field trip of Hwasong fortress, most of students showed positive changes. Some of them reflected on their previous thoughts. Some recognized the necessity of the proper criteria for scientific excellency of historical heritage. All changed in their perspective on evaluating scientific aspects on historical heritage, such as considering the social environment, scientific principles and the influence of science and technology of that age on the society, when the fortress was built. These results show that the science field trip focused on the criteria for evaluating the scientific excellency of historical heritage was significant in helping students to develop the scientific perspective on historical heritage.

Journal of The Korean Association For Science Education, volume 24, issue 5, 2004, Pages 937~945
In this study, we examined high school students' abilities for solving problems under single concept situations and complex concept situations and their mental capacities. Single concept situations are defined as the problems which can be solved with a scientific concept or principle and complex concept situations are the problems combined with more than 2 single concept situations. 152 11th-graders were participated in this study, who had taken natural science track. FIT 752 was used to measure their mental capacities. And an instrument, made up of six questions under three single concept situations and three complex concept situations, was used to assess students' problem solving abilities. As results, students' problem solving abilities were lower in complex concept situations than in single concept situations. There wasn't significant difference in mental capacities between of students who succeeded in solving problems and ones who did not under both single and complex concept situations. Although students solved the problems of single concept situations, some of them failed in solving the problems of complex concept situations composed of single concept situations which they succeeded in solving. They belonged to relatively low mental capacity group, of which students who failed in solving problems of complex situations had lower metal capacities than ones who succeeded in solving them. According to these results, it could be concluded that mental capacity is one of main variables which have influence on problem solving of complex concept situations composed of solvable single concept situations.

Lee, Mee-Kyeong ; Jeong, Eun-Young ;
Journal of The Korean Association For Science Education, volume 24, issue 5, 2004, Pages 946~958
The purpose of this study was to investigate factors in school science influencing students' attitudes toward science. In order to achieve the purpose, a total of 1,002 students at 5th, 7th, and 10th grade levels was sampled and surveys were carried out to examine attitudes toward science and reasons that students liked and disliked science. According to the results, male students liked science more than female students did at all grade levels and 10th graders liked science less than 5th and 7th graders did. The main reason that students liked science was experiments. And the main reason that students disliked science was science teaching methods including science activities, instructional materials, science textbooks and science teachers. Among the reasons that students liked science, factors that affected attitudes toward science were contents and characteristics of science subjects and experiments. Among the reasons that students disliked science, factors that affected attitudes toward science were experiments and science teaching methods. The results suggest that it is desirable to apply appropriate methods according to students' interests in science to develop positive attitudes toward science effectively.

Journal of The Korean Association For Science Education, volume 24, issue 5, 2004, Pages 959~976
The purpose of this study was to investigate high school students' ideas related with dinosaur extinction, to classify students' responses types with alternative hypotheses of inconsistent with their ideas, and then to examine their cognitive conflict levels and the degree of ideas change. To investigate students' ideas, we analyzed responses 98 eleventh graders of a high school in Anyang area. The results of this study were as follows: First, most of the students responded a large scale asteroid impact with the cause of dinosaur extinction, and rest of them responded changed Earth's climate accompanying tectonic activity, extreme volcanic activity, shortage of food, disease(virus) and decrease of their habitat. Also, they thought that dinosaur was exterminated not by just one reason but by several complex reasons. Second, the students' responses of alternative hypotheses were classified into six types: rejection, reinterpretation, uncertainty, belief decrease, partial theory change, and theory change. Third, except rejection and reinterpretation types, other four types were arousing of cognitive conflict and the percentage of the students who felt cognitive conflict was 62.3% and that of the students who took the theory change was just 6.1 %.

Journal of The Korean Association For Science Education, volume 24, issue 5, 2004, Pages 977~986
The purpose of this study was to investigate the general transfer effects of Thinking Science program on the problem solving with compensational reasoning of the elementary school students. For this study, 156 5th grade and 138 6th grade students were selected from four elementary schools. The students were tested with SRT(Science Reasoning Task) and compensational reasoning task. Statistically significant gains on the development of compensational reasoning were shown by the experimental group implemented with Thinking Science activities compared to the group implemented with compensation activity only. The achievement of the experimental group was higher than that of the compensation activity group in solving problem with compensational reasoning, specially for the boys and students in both the mature concrete and the concrete generalization stage. The results of this study implied that implementation of Thinking Science program related to several formal reasoning were effective for the development of reasoning ability as a general-transfer.

Journal of The Korean Association For Science Education, volume 24, issue 5, 2004, Pages 987~995
The purpose of this study was to analyze characteristics of problem solving process with proportional or compensational reasoning of the elementary school students. For this study, 85th grade students were selected and tested with Science Reasoning Task, information processing ability test and proportional and compensational reasoning tasks. This study revealed that students in mid concrete stage could solve the proportionality task and easy compensation task. But, most of the students could not solve difficult compensation task. And as the students got higher score in information processing test, it took them less time to solve the problem. The types of strategy used in solving proportional and compensational problem were categorized as the factor of change, building-up and the cross-product. Most of the students failed in problem solving used incorrect schema knowledge, procedure knowledge and strategy knowledge. Many students tended to use proportionality strategy to solve the difficult compensation task. Result of this study suggested that various task included different structure and the same schema knowledge can be effective for the advancement of students' proportional and compensational reasoning ability.

Journal of The Korean Association For Science Education, volume 24, issue 5, 2004, Pages 996~1007
In this study, we investigated the effects of small group discussion using episodes from the history of science on students' understanding about the nature of science (NOS), achievement, enjoyment of science lessons, and science learning motivation. Participants were 138 ninth graders from a middle school in Seoul and they were assigned to a control group and a treatment group. Students in the treatment group were provided with two contrasting perspectives concerning the NOS and were encouraged to discuss them in small groups. The intervention lasted for 5 class periods. The results revealed that students of both the control group and the treatment group were found to possess similar views about NOS in a NOS pretest, whereas students of the treatment group exhibited more sophisticated understanding in a NOS posttest. The scores of the treatment group were also significantly higher than those of the control group in an enjoyment of science lessons test and a learning motivation test. However, there was no significant difference between two groups in the achievement test scores.

Journal of The Korean Association For Science Education, volume 24, issue 5, 2004, Pages 1008~1017
In physics education, language is an fundamental learning tool as in other subjects. In writing activity, students can get fair opportunities to express their own ideas during the class. Even though there are various styles of writing, students are usually supposed to make a report in their science classes. But there have been few studies in science education on the tasks and features of student's science writing. In this research, different styles of writing tasks were designed for science classes, and students' writing was analysed in terms of conceptual and emotional aspects. Also the usefulness of each task type was discussed relating to school physics education. Four types of writing, i.e.
writing were developed, and 'The reflection of light' was selected as the theme and given to students. Four types of writing were analysed in this paper. In each type of writing, students showed different features in their conception. They also showed emotional expressions in imaginative writing types, that is,
types. Based on these results, it is recommended that in physics teaching various types of writing need to be designed, developed and applied according to the aim of a particular lesson.

Journal of The Korean Association For Science Education, volume 24, issue 5, 2004, Pages 1018~1027
The purpose of this study was to identify and compare the types of scientific questions which were generated by elementary students and preservice teachers on the tasks of scientific observation. To identify the types of scientific questions, 4 observing tasks, dry grapes contained in soda pop, candlelight, celery, and a rock were administered to 40 sixth elementary students and 20 elementary preservice teachers. And then, the types and frequency of scientific questions generated by them were compared. The results showed that the types of scientific questions were classified into conjectural questions, causal questions, predictive questions, methodical questions and applicative questions. Further more, subordinate questions to the above questions were classified into object exploration questions and object verification questions, explicans exploration questions and explicans verification questions, result exploration questions and result verification questions, example exploration questions and example verification questions. Subordinate questions did not come out from the methodical questions. The types of scientific questions generated by elementary students and preservice teachers were identical, however, there were differences in frequency. This study supports that elementary students also have cognitive capability to generate various scientific questions. The results of this study may be used as a teaching strategy for the guidance of the direction and the method of scientific inquiry.

Kwak, Young-Sun ;
Journal of The Korean Association For Science Education, volume 24, issue 5, 2004, Pages 1028~1038
This study investigated how the 7th national elementary school science curriculum was implemented at science classrooms. Data from surveys with 140 elementary schools, 18 science classroom observations, and in-depth interviews with teachers were used to examine the characteristics of elementary school science instruction. Based on the data, I explored (1)how science curriculum is operated in terms of objectives, contents, methods and evaluation of school science, and (2)how student-centeredness and localization themes are reflected on the reconstructed school science curriculum. It was found that the degree of the reorganization of the national curriculum at the teacher level was minimal. And most of the elementary teachers followed the directions and contents of the science textbook and teacher's guidebook regardless of their own local situations. For most teachers, restructuring science curriculum meant reordering the sequences of the contents, and adding or deleting some units or topics. I also examined why elementary teachers have difficulty in reconstructing science curriculum at the classroom level. The necessity of curriculum reconstruction at the teacher level is also discussed.
