The purpose of this study was to analyze one science teacher's understanding of student argumentation and his explicit teaching strategies for implementing it in the classroom. One middle school science teacher, Mr. Field, and his students of 54 participated in this study. Data were collected through three semi-structured interviews, 60 hours of classroom observations, and two times of students' lab reports for eight weeks. Coding categories were developed describing the teacher's understanding of scientific argumentation and a description of the main teaching strategy, the Claim-Evidence Approach, was introduced. Toulmin's approach was employed to analyze student discourse as responses to see how much of this discourse was argumentative. The results indicated that Mr. Field defined scientific inquiry as the abilities of procedural skills through experimentation and of reasoning skills through argumentation. The Claim-Evidence Approach provided students with opportunities to develop their own claims based on their readings, design the investigation for evidence, and differentiate pieces of evidence from data to support their claims and refute others. During this approach, the teacher's role of scaffolding was critical to shift students' less extensive argumentation to more extensive argumentation through his prompts and questions. The different level of teacher's involvement, his explicit teaching strategy, and the students' scientific knowledge influenced the students' ability to develop and improve argumentation.

The present study tested the hypothesis that maturation of the prefrontal lobes is a crucial factor determining the performance of scientific reasoning tasks, Functions of the prefrontal lobes, such as activating relevant information, sequential planning and monitoring, and inhibiting irrelevant information, are related thinking patterns with scientific reasoning. Therefore, we inferred the idea that the prefrontal lobes play an important role in scientific reasoning. To test the hypothesis. the present study investigated a prefrontal lobe patient's task solving procedures in scientific reasoning tasks and the correlation and regression analysis between a test of prefrontal lobe function and two scientific reasoning tasks, The perseverative errors in the Wisconsin Card Sorting Test(WCST) was used as a measure of the prefrontal lobe function, The Melinark Type Task and the Classroom Test of Scientific Reasoning were used as measures of scientific reasoning abilities. Ages and Group Embedded Figure Test were also used as measures of two alternative hypotheses, general maturation and field independency respectively. The prefrontal lobe patient showed a crucial deficiency in solving scientific reasoning tasks. In the tasks, the patient could not used the reasoning of If... and... then... therefore pattern. In correlation study, the perseveration errors of the WCST showed a significantly negative correlation with two scientific reasoning tasks. Multiple regression study also showed that the perseveration errors measured as a function of the prefrontal lobes have more contribution to scientific reasoning ability than contributions of alternative hypotheses. Therefore, the present study supported the hypothesis that prefrontal lobes play a crucial role in scientific reasoning ability, What function of the prefrontal lobes do play crucial role in scientific reasoning? The present study provided an explanation for the question, which inhibiting ability of the prefrontal lobes is responsible for the scientific reasoning ability, in a part at least. That is, perseverative tendency in task-solving procedures causes a deficiency of an ability to inhibit the wrong information to solve a task. The present study provided a possibility of neuropsychological approach in science education research. The present study also showed an importance of the prefrontal lobe development in the performance of scientific reasoning task.

In addition to exceptional abilities and domain-specific aptitudes, frequently creativity potentials are used to explain high achievements in science and technology. In the Guilford tradition, research focuses increasingly on convergent versus divergent thinking, that is, a suspected dichotomy between intelligence and creativity. Despite important insights from this about relationship of ability and creativity, a number of important questions remain unanswered. These relate not only to conceptualization and measurement problems regarding the hypothetical constructs "scientific ability" and "creativity", but also their diagnosis and nurturance in childhood and adolescence. It would appear that, in view of current research paradigms, the role of ability and creativity needs to be redefinded in order to more reliably predict and explain excellent achievements in science and technology. Advances are mostly expected from synthetic approaches. Thus, I will be presenting new theoretical models and empirical research results. Finally, consequences for the prediction and promotion of mathematical-scientific and technical talents will be discussed including the consideration of sex-related problems.

This article is a part of a research on the elementary science curriculum development to enhance creative problem-solving abilities. The components of the curriculum have been identified as 'scientific knowledge', 'process skills' & 'divergent/critical thinking'. Among these components, construction of the scientific knowledge that enables creative problem-solving abilities has been selected as an intensive research topic for the purpose of the present research. To avoid or to prevent the knowledge learned from separate facts and concepts, five themes have been selected so as to incorporate with all three areas of the elementary science curriculum, i.e., physical science, earth science and life science. The five themes are, 'structure', 'change', 'interaction', 'energy' and 'stability'. The contents of elementary science, which have been selected from the 3rd, 6th and 7th National Elementary Science curriculum, were reconstructed based on the five themes given above. The results of reconstruction are presented in the form of matrix, such that the vertical axis represents how the concepts are related within each domain of science, while the horizontal axis shows how the concepts are interconnected between domains of science. Therefore, based upon the five themes, individual or separate knowledge can be put into more unified knowledge so that contribution of knowledge transfer to new ones can be expected for leaners who will be creative in problem-solving. The process and products of the curriculum development as well as the background of the present research are described and discussed in detail.

While scientific explanation is a fundamental component of science, teachers often lack familiarity with the formal structure of scientific explanations and the criteria for assessing their quality. Consequently, this study aims to clarify the concept of scientific explanation and proposes a tool for constructing scientific explanations. The primary objective is to explore the tool's impact on enhancing the explanatory skills of pre-service teachers when it comes to the phenomenon of condensation. The research findings indicate that many pre-service teachers initially operated at a description level during the pre-test. However, the implementation of the tool enabled them to advance their explanatory skills beyond the associative level. Notably, the tool was analyzed for its ability to provide pre-service teachers with a conceptual framework for explaining phenomena and guiding logical explanations and micro-level interpretations. This study holds significance in demonstrating that pre-service teachers can comprehend the formalities and criteria of scientific explanations and apply them to enhance their own explanatory abilities. Moving forward, efforts should be made to enhance the scientific explanation level among pre-service teachers across various topics and subject areas. Furthermore, pre-service teachers need classroom experiences that foster the construction of scientific explanations in authentic contexts.
