Observation is one of the important aspects in science and science education. However. observation has so many varieties that the purpose and the meaning of scientific observations used in science education are different in persons, contexts, and subjects. In this study, we tried to understand the natures of scientific observation and investigated students' observational activities using four observation tasks: candle, double pendulum, iron filings around bar magnet, two electric bulbs connected in series. We required the subjects to observe the given tasks and described what did they observe. Based on students' observational descriptions, students' observational activities could be classified in four categories: primitive, interpretive, operational, and interfered observation. Also, we could find that some of the descriptions were non-observational activities such as predicting and questioning and so on. Finally, implications for the teaching of observation in science education are suggested.

The purpose of this study was to analyze the influence of mental capacity and understanding of the oxi-dation-reduction concepts on the completion of the balancing redox equations. Participants were 92 senior high school students and 57 science high school students. Tests were conducted to measure the mental capacity, the understanding of the oxidation-reduction concepts and the completion of the balancing redox equations and the influence on the per-formance was analyzed. The performance of the senior high school students increased as the mental capacity increased, but the performance of science high school students did not change by mental capacity. Most of senior high school stu-dents couldn't understand the oxidation-reduction concepts well. Most of science high school students, however, under-stood the concepts completely and partially. The students who had a good understanding of the oxidation-reduction concepts showed a good performance for both senior and science high school students, regardless of the problem pattern.

The purposes of this study were to develop an Earth Systems-based program for science-gifted students and to investigate the effects of field application. The developed program was composed of six activities focused on 'fault and earthquake'. Each step including exploratory step, enrichment step and application step was designed to be associated with aims for Earth Systems Education. Two instruments for experiments were produced and students' activity sheets and teacher's guide of the program were developed. The program was applied to 14 science-gifted students who were 8th grade belonging to an institute for science-gifted at an university. Data was collected from students' activity sheets, outcomes and questionnaires. The findings were as follows. First, the results of analyzing the students' activity sheets and outcomes indicated that the program was helpful in understanding the interactions among subsystems of the Earth. Secondly, the results of the survey indicated that positive responses in acquiring scientific concepts and the results revealed science-gifted students were much interested in this program. Many students perceived that the level of program was appropriate for the science-gifted students, a few students perceived that the level of contents was high.

This study aims to examine genetics problem-solving processes of high school students with different learning approaches. Two second graders in high school participated in a task that required solving the complicated pedigree problem. The participants had similar academic achievements in life science but one had a deep learning approach while the other had a surface learning approach. In order to analyze in depth the students' problem-solving processes, each student's problem-solving process was video-recorded, and each student conducted a think-aloud interview after solving the problem. Although students showed similar errors at the first trial in solving the problem, they showed different problem-solving process at the last trial. Student A who had a deep learning approach voluntarily solved the problem three times and demonstrated correct conceptual framing to the three constraints using rule-based reasoning in the last trial. Student A monitored the consistency between the data and her own pedigree, and reflected the problem-solving process in the check phase of the last trial in solving the problem. Student A's problem-solving process in the third trial resembled a successful problem-solving algorithm. However, student B who had a surface learning approach, involuntarily repeated solving the problem twice, and focused and used only part of the data due to her goal-oriented attitude to solve the problem in seeking for answers. Student B showed incorrect conceptual framing by memory-bank or arbitrary reasoning, and maintained her incorrect conceptual framing to the constraints in two problem-solving processes. These findings can help in understanding the problem-solving processes of students who have different learning approaches, allowing teachers to better support students with difficulties in accessing genetics problems.

The purpose of this study was to develop the elementary school science instructional material for nurturing students' creativity and to analyze the effects of this material on the changes of students' creativity. This material was composed of student's worksheet and a teacher's guidebook, in which are relevant to the elements of creativity and creative activities that can be applied to elementary science curriculum of 5th and 6th grades. Student's worksheets include various creative activities: imagination, guided imagery, experimental activity, mind mapping as wrap-up, and 'let's think' as an extended activity, game, puzzle, making a cartoon, to be, role playing, and so on. These materials were applied to 5th grade science class, 156 students. They were divided into two groups: the treatment group to which developed material was applied and the control group which was a traditional lecture-centered class. After this material had been applied for 3 months, students of both groups took a test of creativity. Interviews and observation were also carried out with three level groups (higher, medium and lower level) which were divided within the treatment group based on their creativity score. The results of this study were as follows: The treatment group showed higher score on creativity than that of control group(p<0.01). In the result of interviews and observation, the students of the higher and the medium level accomplished their tasks by themselves better than those on lower level.All of them took an interest in visual activity. In a wrapping-up step, the higher level students made mind map more systematically and the medium students improved as time goes on, but low level students feel constrained. In totally, they used various expression methods and were interested in making drawings and cartoons creatively.

The purpose of this study is to identify the differences of argumentation discourses for Socio-Scientific Issues in the types of decision-making and personality traits of pre-service biology teachers. For this study, SSI discussion topics were selected according to four types of decision making: logical reasoning, suggestion of complement, emotional base, and internal conflict. Three groups were constructed based on personality traits such as extroversion, acceptability, and integrity. Each three group used the workbook specially developed and freely used the smart device for discussion. A recorder and a camcorder were used to record each group, their behavior was recorded and the written materials during the discussion were collected for the results. Using Walton's analysis framework, the collected data analyzed in terms of the source of utterance, the process of dialogue shift, and the critical movements that can judge the reasoning of utterance. As a result of the study, it was confirmed that the decision-making type of SSI topics and learners' personalities were influential in the decision-making process of SSI small group discussions. This research shows that there is a need to develop instructional materials considering decision-making types and learners' personality types of students as well as pre-service teachers for SSI discussion.

In this study, we applied a web-based education system to the teaching-demonstrations of the pre-service teachers and identified the usefulness of the system as a method supporting constructive education for pre-service teachers. The pre-service teachers performed the web-based activities for the teaching-demonstrations, and we interviewed them after the teaching-demonstrations. On the basis of the results, we found three situations showing the usefulness of the web-based education system. First, the pre-service teachers examined the materials on the constructive teaching-learning theories and constructed the related theoretical knowledge. At this point the web-based discussion board supported the environment where they thought deeply and investigated the theories carefully. Second, they experienced interaction with others and the academic adviser in the processes of preparing the teaching-demonstrations. This interaction was supported by web-based discussion board, and they were able to form the practical knowledge related to the planning and building constructive teaching. Third, they reflected on their own teaching after the teaching-demonstrations. At this point, the web-based discussion board was able to facilitate the interaction for the reflective thinking processes. In this study, we identified that the web-based education system could provide an effective environment where the pre-service teachers could learn constructive teaching-learning methods.

Calculus is used in various parts of human life and the basis of social science such as economics and public administration. Yet that is still considered important in the field of science and technology only, and there have been a lot of disputes on that phenomenon. Fortunately, calculus is going to be taught as part of the academic high school second-year mathematics curriculum in and after 2010. Students who face calculus for the first time should be helped not to lose interest in differentiation learning, not to be apprehensive of it nor to avoid it. The purpose of this study was to examine the types of errors made by students in the course of solving differentiation problems in an effort to lay the foundation for differentiation education. A pilot test was conducted after generalized differentiation problems to which students were usually exposed were selected, and experts were asked to review the pilot test. And then a finalized test was implemented to make an error analysis according to an error type analysis framework to serve the purpose.

The purpose of this study is to analyse the cases related with PBL and to suggest the activation plan of LAI based on the derived results. The analysis objects were the PBL cases which have been performed from 2000 to 2018 in Korean schools. The PBL cases were analysed in the aspects of school levels, target grades, subject clusters, teaching patterns, information sources, cooperative teaching status, library cooperative teaching status, and educational effects. The results were like these; 1)The PBL was applied at the elementary schools the most, the next middle schools, and high schools. 2)The teaching pattern was the exclusive teaching the most, and the next pattern was team teaching with other teacher, and the lowest pattern was with librarian teacher. 3)The subject cluster was natural science cluster the most and the next was the human & social science cluster and the art, music and physical education cluster. 4)The PBL performed with school library was low. 5)The main effects of PBL were the improvements of academic achievement, learning satisfaction degree, creative ability, problem-solving ability, and self-directed learning capability. As the results, it's proposed that it's important for librarian teachers to have the aggressive attitude for the activation of LAI as well as the cooperation with PBL subject teachers from the planning step to the evaluation.
