  • This study aimed to analyze the relationship between the observation ability and scientific creativity of elementary students through observation learning of outdoor plants and to identify the factors that influence the two constructs. The study recruited 21 fifth-graders in Seoul. After evaluating observation ability and scientific creativity through observation tasks, qualitative data were obtained through interviews with students about their observation of the plants. Additionally, the study collected various materials, such as the observation records and worksheets of the students to verify the validity of research. The main results of this study are as follows. First, the students were first classified into four groups according to levels of observation ability and scientific creativity. The result demonstrated that the higher the level of observation ability, the higher the level of scientific creativity. Second, observation ability and scientific creativity pointed to a positive correlation. Furthermore, originality, which is one of the components of scientific creativity, indicated a weak positive correlation with observation ability. Third, the factors that influenced observation ability were frequency of plant observation and interest and cooperation in observation learning, and those of scientific creativity were observation ability and the level of plant-related knowledge. Lastly, the study discussed educational methods for improving observation ability and scientific creativity.

  • Scientific observation has been recognized as one of the fundamental aspects in scientific inquiry. However, more detailed discussions and practical guides for teachers' and students' understanding about the nature of scientific observation have not been conducted. Therefore, based on literature reviews, we described the nature of theory-laden scientific observation as 11 detailed statements. Using theses statements, we investigated science teachers' and students' recognition of each statement. According to results, certain aspects of theory-laden scientific observation were determined as important aspects to be considered for science teachers' in-service programs or for students' learning activities in understanding the nature of science.

  • The purpose of this study is to investigate the meaning and process of scientific observation. Hence, this study reviewed and discussed meanings and process of scientific observation described in philosophy, the philosophy of science and science education. Major researches on scientific observation are focused on a characteristic and type of scientific observation behavior. These research can suggest what is the characteristic of observation facts generated by observer. But it cannot show what is the meaning and process of scientific observation, it should be provide to students. According to the result in this study, scientific observation is affected by observer's subjective factors, such as experience, background knowledge, interpretation(not inference) and observation skill. All factor are integrated as an intellectual framework, and it is able to be changed by the observed facts. On the other hand, inference is excluded on scientific observation, but it have constantly affect on intellectual framework through feedback. This study on scientific observation provides a scaffold in various activities of scientific observation to be provided to students.

  • The purpose of the study was to investigate the effect of observation knowledge generation based on a scientific observation strategy in 6th grade students. In this study, we selected the topics related to the observation in elementary science curricula and developed worksheets and guidelines such that subjects accomplished the systematic observation based on the method and strategy of the observation knowledge generation. Seventy-five 6thgraders, 38 for the experimental group and 37 for the control group, were chosen for this study. The experimental group was taught the science lessons with 14 sessions based on the generation of various scientific observation types, whereas the control group was provided with traditional lessons. Before and after the treatment, a candle-burning task was set for subjects to test the effect of the lessons of scientific observation knowledge generation. According to the results, subjects in the experimental group were more effective in the generation of various observations than subjects in the traditional one. The observation abilities of the experimental group was shown statistically to have a significantly higher performance in richness and the diversity. In addition, they showed higher scores in the scientific observation ability task than the control one. Therefore, the systematic lesson strategy in scientific observation is presumably effective to improve students' ability of scientific observation knowledge generation.

  • The purpose of this study is to examine the effect of PBL-based astronomical observation on the science process skills and scientific attitudes in elementary science-gifted students. To verify research problems, the subjects of this study were forth-grade students selected from one classes of an elementary science-gifted class in Busan National University of education : the research group is composed of twenty students who were participated in PBL-based astronomical observation program. During four weeks, the PBL-based astronomical observation program instruction was executed in the reasearch group. Post-test showed following results: First, the research group showed a significant improvement in the science process skill. We look into detailly this, the research group showed a significant improvement in the basis science skill. The sub-factor 'expectation' of the science process skill effects a significant improvement. Second, the research group showed a significant improvement in the scientific attitudes. In conclusion, PBL-based astronomical observation program was more effective on science process skill and scientific attitudes. However, since the study has a limit on an object of the study and the applied program, the additional studies need to be conducted with an extended comparative group and program.

  • This research attempts to extract the factors that generate scientific interest, and verify the effect of extracted factors on the generation of scientific interest in middle school students' observation activity on life phenomenon. In order to analyze interest-generating factors, observation programs were applied four times in the science class of 3rd grade middle school students. And an interview was conducted towards students who had strong scientific interest among students who participated in the observation activity. After classifying the interview results according to the types, and 21 interest-generating factors were extracted. Interest-generating factors were classified into 5 categories; the characteristics of the observation object, the characteristics of the observation activity, the characteristics of the observation result, the characteristics of the observer, and the characteristics of the extrinsic factor. It was verified that interest-generating factors have an effect on the generation of scientific interest in the observation activity. First of all, in order to confirm whether the extracted generation factors would have an effect on the generation of interest in observation activity, as survey of interest-generating factors was drawn up. The observation activity program of 4 times' volume was applied towards third grade middle school students, and survey paper on interest-generating factor was input. Analysis result showed that factors have effect on the generation of interest. That is, it was confirmed that extracted interest-generating factor has a significant effect on the generation of scientific interest. The cause analysis on the uninteresting observation activity was possible, and it would play an essential role in developing an interesting observation activity.

  • This study aims to investigate how pre-service elementary school teachers understand 'something scientific', 'being scientific', 'scientific events' and 'scientific questions' through semantic network analysis. To achieve this purpose, this study carried out a central analysis of the frequency and density of words and the degree of connection between key words, a concentric analysis, a click analysis and a common network analysis through text semantic network analysis by using NetMiner 4.0 Program. Based on the results of these analyses, this study came to the following conclusions. Firstly, in perceiving 'something scientific', pre-service elementary school teachers recognized 'verification', 'objective' and 'experiment' as most important words. In other words, they perceived that main grounds for something scientific should be provided through clear facts, possible to be verified and accompanied by an exact and logical theoretical system. In regard to 'being scientific', they perceived 'explanation', 'objective' and 'verification' as most important words, while having a traditional point of view that science is a set that can be explained objectively. Secondly, in regard that the term, 'observation', is contained in 'scientific events', they showed a high rate of understanding it as a scientific event. In regard to scientifical reasons, they showed the highest frequency of 'observation', and for unscientific reasons, they showed the highest frequency of 'behavior'. In perceiving 'scientific questions', they showed the highest frequency of determining bacteria-related questions as scientific. As a reason why they thought as scientific, they mentioned 'observation' most frequently like 'scientific events', while mentioning 'value judgement' as a reason why they thought as unscientific most frequently. From the results of integrated network analysis, this study found out that words pre-service teachers commonly used in stating scientific events or scientific questions were overlapped with words they mentioned for scientific events or scientific questions. As a result, it was found there were many pre-service teachers having interpreted scientific words without clearly distinguishing scientific events or scientific questions.
