It is well known that high school girls' mean achievement levels in science tests are lower than high school boys' and that fewer women than men are employed as scientists and engineers pursue scientific careers. Many research attributed the sex difference in achievement level in science and the lack of women in science among others, to the experiential differences in scientific activities and the differences in attitudes toward science and scientists. Therefore, the study had its object to examine the sex difference by high school students in scientific experience and attitudes toward science and scientists. The differences in science experiences were identified at eight schools over rural and urban areas in Kangwon province. Science activities surveyed included use of experimental materials and instruments, observation of scientific phenomena, and extracurricular scientific activities. Attitude scale contained the nature of science, scientific research methods and philosophical views held by scientists. The study found sex differences in scientific experiences and attitudes. i. e.: fewer high school girls than boys had experience with scientific activities, especially with extracurricular activities; however, girls had more positive attitude toward science and more active desire to participate in science. Consequently, the study implies that, in order to narrow the gaps between achievement levels for boys and girls, science education should take consideration of the sex difference in experiences with and attitudes toward science.

The purpose of this study was to investigate the effects of science toy making activities on the scientific interest and the conceptual understanding of elementary school students. In this study, science toy making activities were applied to an experimental group and traditional learning activities were applied to the control group. The science toy making activities comprised thirteen steps and were administered during class. In the scientific interest test, there was a statistically significant difference between the score of the experimental group and that of the control group. In particular, post-test scores were higher than pre-test scores in the experimental group, while they were lower than this in the control group. It appeared that students had positive thoughts about science toy making activities. These science toy making activities had positive effects on the conceptual understanding of the experimental group students. The post-test scores of the experimental group were higher than that of the control group in all domain concepts. From these results, it can be deduced that the science toy making activities were more effective than traditional teaming activities. They were an effective teaching technique which enhanced the scientific interests and the conceptual understanding of the students in question.

This research centers around an experiment conducted to determine the relative effectiveness of constructivist cooking activities as compared to traditional cooking activities for young children. Forty-six children, aged five years in two kindergarten classes were assigned to a experimental and comparative group. The experimental and comparative group participated in 12 units. The experimental group participated in the constructivist cooking activities, while the comparative group participated in the traditional cooking activities. Analysis of covariance revealed significant differences between the mean scores of the two groups on the posttests for scientific attitudes and creativity, indicating that the children in the experimental group performed significantly better on the tests than the children in the comparative group. The results of this study suggest that such constructivist cooking activities are able to improve the scientific attitudes and creativity of young children.

This study focuses on the knowledge-transfer activities of Korean universities at the organisational level. Considering the idiosyncratic characteristics of the Korean university system, as well as those of universities in other recently developed Asian countries experienced a rapid economic catch-up, this study is more interested in the relationship between the scientific capacity of universities and their knowledge-transfer activities, and between universities' funding sources and their knowledge-transfer activities. According to the results of the study, scientific capacity in a specific discipline, such as engineering, is important for universities in both other developed countries and in Korea, while scientific capacity (regardless of the discipline) is apparently not important for Korean universities, particularly in the area of domestic publication. Furthermore, this result supports the proposition suggested that strategically chosen industrial sectors in rapid catch-up countries are closely related to the scientific capacity of universities in specific disciplines. In terms of funding sources, the amount of funding from industry is strongly related to the knowledge-transfer activities of universities, whereas the proportion of funding from industry relative to the total amount of funding is not as significantly related to knowledge-transfer activities. The failure to identify a significant relationship between central government funding and knowledge-transfer activities may be due to less strict requirements for commercialisation in central government R&D programmes. Otherwise, central government funding fails to generate meaningful knowledge-transfer activities in universities.

The purpose of this study was to investigate the characteristics and proprieties of the granite observing results in the 4th grades elementary students' scientific inquiry activities. For this, the 4th, 94 students participated in granite observing activity which had objects to collecting applicable scientific facts for the distinguishing granite among the volcanic rocks. Following are the study results. First, the 829s of total results (879s) were admitted as the facts, but the rest, 50s were not the facts but the inference results. Second, the 542s results which were related to the shape, weigh, size, smell, sound, and touch (feeling) containing glittering of the rock specimen were the useless for the inquiry objects. And only the 85s results were the scientific facts which were deserved the admitting propriety for the inquiry objects. Third, the 185s results which were targeting to the particles (minerals) on the rock specimen were the admitting facts, but the 163s facts which were related to color, size and shape of the particles were deserved as admitting propriety for the inquiry objects. Consequently, the focusing on the proprieties of the granite observing results in the elementary students' scientific inquiry activities, only the 248 results (28.2%) of the total 879s were the admitting proprieties as the meaningful scientific facts in the scientific inquiry activities.

This study was conducted based on the fact that children in institutions for early childhood education located in cities lack the opportunity to experience nature. Therefore, urban parks are where it is possible to observe nature and natural environment, through which we examined the effects of nature activities on kindergarten children's curiosity and scientific problem-solving ability. The subjects of this study were 5-years old kindergarten children in attending public kindergartens in Cheonan and Asan and 42 children were randomly selected. The pretest and posttest were conducted on curiosity and scientific problem-solving ability before and after nature activities. The results showed that nature activities in urban parks had significant effects on improvement of kindergarten children's curiosity and scientific problem-solving ability (p <.05). Therefore, nature activities in urban parks had positive effects on preference for unknown and exploratory behavior, which are sub-factors of kindergarten children's curiosity. Nature activities also had positive effects on discovery and statement of the problem, creation and application of ideas, and conclusion to problem solving.

In this study, it is assumed that understanding the nature of science (NOS) would enhance students' performance of scientific inquiry in more authentic ways. The ultimate goal of this study is to suggest new models for developing scientific inquiry activities through understanding the NOS by linking the NOS with scientific inquiry. First, the various definitions and statements of the NOS are summarized, then the features of the developmental nature of scientific knowledge and the nature of scientific thinking based on the philosophy of science are reviewed, and finally a synthetic list of the elements of the NOS is proposed, consisting of three categories: the nature of scientific knowledge, the nature of scientific inquiry, and the nature of scientific thinking. This suggested synthetic list of the NOS is used to suggest a model of scientific inquiry through the understanding of the NOS. This list was designed to provide basic standards regarding the NOS as well as practical guidance for designing activities to improve students' understanding of the NOS.

The purpose on this study is to identify how effectively experiential learning involving eco-activities make changes in environmental literacy and scientific attitude of elementary students by categorizing those activities into 5 fields of "marine", "rivers", "ecosystem", "climate" and "recycling" and applying those scheme specifically to 5th graders in a elementary school. The conclusion of this study is following. Firstly, after scientific attitude are applied to subjects, a significant disparity was found between experiment group and control group throughout all parts of environmental literacy. In the cognitive category, each specialist concerning his or her own topic was invited to educate the students, and subsequently a positive impact was detected in the category of environmental issue knowledge. In behavioral category, having eco-activities made a significant disparity in all sub-categories of environmental function, active participation, saving activities, recycling activities and so forth. Secondly, experiential learning involving eco-activities made a significant disparity between the two groups in terms of Scientific Attitude, showing effectiveness in all sub-categories except curiosity.

The purpose of this study was to investigate the characteristics of lesson planning of pre-service elementary teachers to develop scientific communication skills for elementary school students. For this purpose, lesson plans and lesson planning journals written by the 53 pre-service teachers were collected and analyzed. The results of the research were as follows. The pre-service elementary teachers used an implicit and contextual approach to develop scientific communication skills. Teaching and learning activities for enhancing scientific communication were mainly conducted in words or in writing. There were many activities expressing elementary school students' thoughts and presenting the results of experiments in the lesson plan. There were many cases in which the pre-service teachers' lesson plans did not include the evaluation of scientific communication skills. In their lesson plans, there are a lot of mutual activities between teachers and students, team and whole students, and inter-students within teams together, and students' individual activities from requests of teachers. We found that the pre-service teachers had various difficulties when they planned the science lesson to develop scientific communication skills. The pre-service teachers were less likely to refer to specialized materials related to science education when planning their classes.
