  • The purpose of this study is to examine the effects of small group inquiry skills on improving science process skills and attitudes toward science in elementary school science. The research questions of this study were as follows. First, effects of small group inquiry skills on improving science process skills in elementary school science. Second, effects of small group inquiry skills on improving attitudes toward science in elementary school science. The subjects of this study is two classes from 6th grade elementary classes in Busan. The experiment class practiced small group inquiry skills, while the control class practiced self inquiry. To verify the effect of the experiment, ANOVA was conducted. The main findings of this study are as follows. First, the small group inquiry skills gave a significant influence on increasing the science process skills, including the basic science process skills and the integrated science process skills, of students. Especially, among subordinate factors of science process skills between groups, it was effective to increase abilities of observing, reasoning, interpreting data, formulating hypothesis. It is necessary for teachers to make an effort to teach according to steps of the small group inquiry skills and to support inquiry activities, in order to increasing the science process skills. However, frequency of additional lessons have a little influence on increasing the science process skills. Second, there is meaningful change in the attitudes toward science for those who studied the small group inquiry skills. Also, they affected subordinate factors of the attitudes toward science, like the attitudes toward science inquiry, the happiness about science class. This study shows that the small group inquiry skills give a positive influence on the science process skills and attitudes toward science in elementary school science.

  • In this study, we analyzed activities in life science chapters of middle school 'science' textbooks for the 2009 revised Korea national curriculum and examined the difference between the analysis based on scientific practices and the analysis based on inquiry skills. As a results, there was a lot of inquiry skills in the order of 'reasoning', 'observing', 'classification' in the all of grade. In scientific practices, 'data analysis and interpretation' and 'constructing explanations and devising problem solving' were biased. This shows that life science inquiry activities in middle school 'science' textbooks are lacking in diversity in scientific practice elements as well as inquiry skills, and that the goals of the activities are limited. In addition, through the interrelationships between scientific inquiry skills and scientific practice elements, we examined contents relevance in the transition from inquiry function center to scientific practice, and compared with the results of inquiry activities in textbook, The results of this study were matched monotonously due to the tendency to basic inquiry-data interpretation / basic inquiry-explanation. This comes from results of the lack of diversity in activities presented in middle school 'science' textbooks. In this study, it is suggested that efforts should be made to include diverse scientific practice elements in the process of realizing 2015 revised Korea national curriculum from the simple and diversity-less inquiry activity through analyzing the textbooks of the 2009 revised Korea national curriculum.

  • The scientific creativity problem solving ability of children has been greatly emphasized in recent years, because it has been regarded as an example of highly developed reasoning and thinking skills. This study aimed to identify the relationships between scientific aptitude, creativity, and scientific creative problem solving abilities in children. The subjects were 100 5th graders residing in Seoul and a small city in Choongnam. Data was analyzed by t-test and by correlation using spss program packages. The main results of this study were as follows: first, a significant difference was found in the scientific creative problem solving ability of children by their respective levels of science aptitude. Secondly, the scientific creative problem solving ability of the children by their levels of creativity was found to be insignificant. Thirdly, no significant difference was found between creativity and scientific creative problem solving ability among the children examined; however there was a significant difference found between the science aptitude and scientific-creative problem solving ability and between science aptitude and creativity in the children who participated in this study.

  • The purpose of the present study was to test the hypothesis that student's abductive reasoning skills play an important role in the generation of hypotheses on pendulum motion tasks. To test the hypothesis, a hypothesis-generating test on the pendulum motion and a prior knowledge test about the length of the pendulum motion were developed and administered to a sample of 5th grade children. A significant number of subjects who have the prior knowledge about the length of the pendulum motion failed to apply that prior knowledge to generate a hypothesis on a swing task. These results showed that students' failure in hypothesis-generating was related to their deficiency in abductive reasoning ability, rather than the simple lack of prior knowledge. Furthermore, children's successful generating hypothesis should be required their abductive reasoning skills as well as prior knowledge. Therefore, this study supports the notion that abductive reasoning ability beyond prior knowledge plays an important role in the process of hypothesis-generation. This study suggests that science education should provide teaching about abdctive reasoning as well as scientific declarative knowledge for developing children's hypothesis-generating skills.

  • This study was analyzing what studying factors are affecting on the development of science process skills of the 5th graders in the elementary school. For this research, 2 hundreds of elementary students were chosen and questioned on 3 factors like teacher, school environment, and learning strategy which are supposed to affect the development of science process skills. According to the result, there were differences in the categories according to the region. Especially, science process skills were significantly different in level of school category(p<.05)). Science process skills were significantly correlated with teachers and school category, and learning environment in 5th grade. Based on these results, it is expected to perform analysis about the influences that studying variables have on science achievement and attitude as well as scientific reasoning ability. Also, further study is needed about the influence that these small difference have on middle and high school students, though studying variables are not statistically significant on this research.

  • The main purpose of this study was to develop a teaching program, especially designed to improve the skills of control variables. The secondary purpose was to investigate the effect of the program on enhancing students' scientific reasoning and understanding. The program was designed based on the 3-step learning model: i.e. students recognize the necessity of controlling the variables (step 1), perform their own experiments (step 2), and reflect on their variables control process (step 3). The program included 9 topics of increasing difficulty. In results, Lawson's SRT scores increased in both experimental and control groups after application of the program, but the difference was not statistically significant. After the application, there was an increase in type A and type B which implied that students' skills of control variables was improved. In addition, responses of students in the experimental group to the open-ended items showed that it was challenging for them to think scientifically and critically when controling variables, but they ended up feeling proud of their achievement after the program.

  • In this paper the negotiation skills, which have been so far known as non-scientific or artistic field, are analyzed on the basis of behavioral science view point. Negotiator's behavior and psychological situation are believed to influence the negotiation result significantly, therefore, those factors are reviewed with behavioral science framework. Some concepts developed in Cognitive Psychology to explain the decision making models - prominence, commitment, escalation of commitment, framing, adjustment and anchoring, endowment effect - are reconceptualized and applied to the negotiation skill analysis and negotiation skill development in this paper. As the results of this research, various negotiation skills which have been so far believed as irrational and artistic are now able to be explained on the basis of sound logic and reasoning. This means also that valuable and elegant negotiation skills should be further developed by behavioral scientists.

  • In this study, elementary students' science communication competence was investigated based on the grammatical features expressed in their language-use in classroom discourse and science writings. The classes were designed to integrate the evidence-based reasoning framework and traditional learning cycle and were conducted on fifth graders in an elementary school. Eight elementary students' discourse data and writings were analyzed using lexico-grammatical resource analysis, which examined the discourse text's content and logical relations. The results revealed that the student language used in analyzing data, interpreting evidence, or constructing explanations did not precisely conform to the grammatical features in science language use. However, they provided examples of grammatical metaphors by nominalizing observed events in the classroom discourses and those of causal relations in their writings. Thus, elementary students can use science language grammatically from science language-use experiences through listening to a teacher's instructional discourses or recognizing the grammatical structures of science texts in workbooks. The opportunities in which elementary students experience the language-use model in science learning need to be offered to understand the appropriate language use in the epistemic context of evidence-based reasoning and learn literacy skills in science.
