The purpose of this research was to determine the effects of the functional lateralization of the brain variables related to the sex, the scientific attitude and the scientific exploration skills. The science instruction is divided in each type of the lecturing class with the experiment class. As for the degree of SMR brainwave activation in each stage are presented while accumulating the brain waves from the right, left and the whole brain waves are analyzed during the science learning activities. It is therefore reasonable to consider the science instruction types and brain lateralization to enhance the science learning effectiveness. Sensorimotor rhythm brainwave as the low Beta is represented well to show the thought process. Category quantification scores and objective scores are calculated to show the visual positioning map for the relationships of the categories by homogeneity analysis.

The purpose of this study was to examine UK students' use of multimodal representations in science. Students were asked to explain their understandings of the scientific concept and presentation of the multimodal representations in a science Assessing Pupils' Progress (APP) task. Participants of this study were fifty-four Year 7 students taught by the same teacher. Students from one class (27 students) were assigned to the experimental group, and then they received instruction encouraging the using of multimodal representations as evidences to support students' claims. One class (27 students) was assigned to the control group and they received instruction with traditional teaching methods. Both groups performed an APP task for assessment. The samples of APP assessments produced by students both from the experimental and control groups were analyzed using an analysis framework of multimodal representations, embeddedness in evidence and understanding of scientific concepts. Data analysis indicated that the students in the experimental group performed better than that of the control group on embeddedness of multimodal representations in the APP task. In addition, there was a significant difference between the two groups in the evaluation of understand of the scientific concepts.

For this study, inquiry-based learning program was developed for promoting elementary students' scientific justification activities based on their uses of scientific evidences. The program was applied to the 5th grade science class to examine the types of evidences and major features of scientific justification activities. Analysis of the data showed that the evidences used by students were classified into knowledge-based evidence, experience-based evidence and authority-based evidence. As for students' justification features, this study reports three major cases: a case evolving evidence and justification to become more valid and logical, as inquiry activities progressed, other case maintaining less valid and illogical evidence and justification, and final case revealing passive and reluctant participation in the inquiry activities. Overall, students' participation in scientific justification process became more valid and relevant, while there were some students who were unable to make the relevant relations between evidences and claims they made. The educational implications were discussed to consider more effective ways to improve the scientific classroom environment through social knowledge construction.

Correct comprehension of the scientific terms is the bottom of understanding the general concepts contained is them. Therefore a study is required to analyze whether the students correctly understand the scientific terms. The associative method was used to evaluate the comprehensibility of the terms. The scientific terms in this study are selected in the textbook of science in the junior high school were selected. The frequency of the same associative word responsed and the frequency of no response from the selected students for given scientific terms were measured for 9 different groups. The terms which are not used in the daily life, especially for the terms with chinese character or abstract terms turn out to be difficult for the students to understand. It is purposed that the instructor should remember the importance of understanding the scientific term and carefully explain them to the science class.

The purpose of this research was to investigate the effect of using digital science textbook on the scientific problem solving of elementary school students. For this research, an instrument to measure student's problem-solving skills was developed. The pretest and posttest scores of one hundred and six 5th grade students' problem-solving skills were analyzed and also the responses of three students who were selected by their levels in the problem-solving science digital textbook class were qualitatively analyzed. The results of this study were as follows; the scores of problem solving skills of science digital textbook groups were higher than that of traditional paper textbook group(p<.05). In the qualitative analysis of the students' reponses in a digital textbook class according to their achievement level, low-achievers' problem-solving skills were much more improved than high- and mid-achievers' skills. In conclusion, science digital textbook has a potential to improve students' scientific problem solving skills, and this possibility will be much higher when science digital textbook is used with teachers' intended instructional goals and strategies like problem-solving lessons.

This study analyzed the types of scientific humors made by scientifically-gifted elementary school students and their perceptions of making scientific humor. For this, 77 students from $4^{th}$ to $6^{th}$ graders of gifted science education center in Seoul National University of Education were selected. Scientific humors made by the students were analyzed according to the number and types. Their perceptions of making scientific humor were also analyzed through a questionnaire and group interviews. The analysis of the results revealed that most of scientifically-gifted students made more than 2 scientific humors, and the number of scientific humor for each students varied from 0 to 11. The most types they made were the descriptive type and the pun using pronunciation type, but they made various types without any special type to be biased. And They made more the dialogue type than the narrative type, especially the riddle type. They used scientific knowledge that preceded the knowledge of science curriculum in their grade level over two or more years. The scientific knowledge of chemistry was used more than physics, biology, earth science and combination field. The name utilization type was more than the characteristic utilization type and the principle utilization type. Scientific humors in the everyday situation were more than humors in artificial situation. The students had various positive perceptions in making scientific humor such as increase of scientific knowledge, increase of various thinking abilities, deep understanding of science concept and principle, increase of interest and motivation about science and science learning, and increase on sense of humor. They had also some negative perceptions related to difficulties in the process of making scientific humor, lack of fun, and lack of time in the class.
