The major purposes of this study are to examine the effects of portfolio assessment on elementary school student's science knowledge, inquiry ability, science attitudes and to investigate students' perceptions on portfolio assessment. Control group consists of 45 fourth-graders at M-Elementary school located at Miwon, Chongwon-gun, Chung-buk and experimental group 36 fourth-graders of G-Elementary school located in Daejeon-si. The inventories of scientific knowledge I, inquiry ability, and science attitudes were administered to both groups as a pre-test. The experimental group was given portfolio assessment instruction and control group traditional instruction for about six weeks. Inventories about scientific knowledge 2, inquiry ability, and science attitudes were administered to both groups as a post-test. A questionnaire on the perception on portfolio assessment was given to experimental group after the treatment. The results were statistically analyzed with SPSS. Control group showed higher score on scientific knowledge than that of experimental group (p<0.5). No statistically meaningful difference was identified in inquiry ability and scientific attitude. More in-depth analysis revealed that scientific attitudes were improved statistically meaningfully by portfolio assessment. The students' perceptions on portfolio assessment is very positive. Students have positive responses on interests in portfolio assessment, feelings of involvement in learning, self-regulated learning, higher levels of thinking, intentions of participation in portfolio assessment.

In this study the authors developed the practice-centered science camp program which was based on the review of out-of-school scientific activities and the standards of HASA (Hands, Head and Heart At Science Activity) curriculum emphasizing on hands-operated skills. After applying this science camp program we confirmed the validity of the program based on the students' responses at the camp. Using students' reports written during the camp and their essays written on the web-site after camp, we analyzed students' responses into four categories; knowledge, inquiry, hands-operated skills, and scientific attitudes. Also we evaluated the components of the science camp programs and students' perception of science and science-related attitudes using a questionnaire before and after the camp. In terms of contents and activities for the development and application of science camp, our result showed that the science camp program should be complemented to connect real life with high-tech science and include more activities related hands-operated skills and competition activities evoking constructive competitive spirits. In conclusion, we can infer that the agencies which take parts of the national policy enterprise related science education, such as Scientific Education Research Center, must develop and specialize science camp program with more competitive human resource system and economic support. Science educators should give more attention on joining school science education with out-of-school science education, which might have a positive effect on students' attitudes and participation toward science.

The purpose of this study is to investigate the characteristics of convergence gifted students through the their perception of the differences about scientists between Science class and Convergence class in gifted science education center. Consequently, this article reports that there are differences in the perception about scientists was distinction between applicants of Convergence and Science class. Science class applicants mainly recognized scientists as pure scientists, but Convergence class applicants recognized scientist were including mathematician, artist, architect, etc. Also Convergence class applicants thought that affective domain including 'effort', 'patience', 'interest' was more important that Science class applicants. On the other hand, when they described the scientists, Science class applicants knew their achievements as scientists more specifically than Convergence class. And to conclude, the characteristics were different between Convergence and Science class applicants in gifted science education center. Based on the result of this study, this paper suggests the following: Firstly, conceptual study is urgent about convergence gifted students in their definition and characteristics. Secondly, information regarding the criteria to select student for convergence class in gifted science education center. Finally, when teaching convergence gifted students, attention should be paid to their characteristics such affective domain.

The Korean Ministry of Education has emphasized the convergent ability for human resource cultivating the development of science and technology in the future. Based on this, Korean STEAM education aims to enhance students' interest and their understanding of science and technology as well as to develop students' convergence thinking and problem-solving skills. Through the camp for gifted students, students are generally introduced to produce self-directed outputs in order to solve the problem in everyday life. In this study, the author aims to find out whether the gifted high school students' creative leader competency and STEAM literacy changed after they experienced STEAM-based camp. 517 gifted students from 52 high schools in the Metropolitan city region join the camp, which is focused on generating student-centered outputs for problem-solving in daily life context. Before and after the camp, the creative leader competency and the STEAM literacy of participants were tested and compared. From the result, we found that the gifted high school students' creative leader competency and STEAM literacy improved after participating in the STEAM camp. In particular, all the sub-factors except for the social value pursuit domains in the social characteristic area of creative leader competency and the areas of creativity, respect, and communication in STEAM literacy increased. Educational implications will be discussed.

This study analyzed the aspect of occupational contents shown in total 24 types of Technology & Home Economics (1). (2) textbooks for middle school in accordance with the 2009 revised curriculum. Analyzing the type of occupation shown in textbooks based on the Korean Standard Classification of Occupations(hierarchical classification), the frequency(ratio), and the aspect of occupational contents in each unit of textbooks and each data type, this study provided basic data to be able to understand diverse aspects of occupational contents. In the results of study, in case of Technology & Home Economics textbooks for middle school, the large area of 'home life' presented occupational contents in the relatively high ratio than the 'world of technology' while the frequency(ratio) of occupational contents was very much different in each publisher, large area, and unit. The occupation name presented in textbooks provided very limited information in the level of 5.27% of occupations presented in the Korea Dictionary of Occupations. Especially, providing occupational information concentrated in professionals & relevant practiceans in the type of the Korean Standard Classification of Occupations(hierarchical classification), it was limited to provide opportunities to learn the diversity related to occupation. Based on such results of study, on top of introducing diverse occupational contents to make students cherish all the occupations, it would be also necessary to seek for institutional measures related to textbook development/career education, so that they could explore career by considering their aptitude and interest.

Transposable elements (TEs) occupy approximately 45% of the human genome and can enter functional genes randomly. During evolutionary radiation, multiple copies of TEs are produced by duplication events. Those elements contribute to biodiversity and phylogenomics. Most of them are controlled by epigenetic regulation, such as methylation or acetylation. Every species contains their own specific mobile elements, and they are divided into DNA transposons and retrotransposons. Retrotransposons can be divided by the presence of a long terminal repeat (LTR). They show various biological functions, such as promoter, enhancer, exonization, rearrangement, and alternative splicing. Also, they are strongly implicated to genomic instability, causing various diseases. Therefore, they could be used as biomarkers for the diagnosis and prognosis of diseases such as cancers. Recently, it was found that TEs could produce miRNAs, which play roles in gene inhibition through mRNA cleavage or translational repression, binding seed regions of target genes. Studies of TE-derived miRNAs offer a potential for the expression of functional genes. Comparative analyses of different types of miRNAs in various species and tissues could be of interest in the fields of evolution and phylogeny. Those events allow us to understand the importance of TEs in relation to biological roles and various diseases.

In this study, we analyzed the PCK components in the materials units of the third and fourth grades of the Korean government-authorized teacher's guides for elementary school, developed in the 2015 revised national curriculum. The results showed that the PCK components were presented in a relatively balanced manner compared to the teacher's guides for middle school. Knowledge of the subject matter accounted for the highest proportion, and knowledge of instructional strategies in science accounted for a higher proportion than knowledge of the science curriculum. The knowledge of assessment in science showed the greatest deviation among publishers, and knowledge of students tended to show the lowest. By subcomponents, experiments and inquiries had a higher proportion than concepts and theories. The ratio of horizontal articulation was lower than that of vertical articulation or lesson objectives, and lesson objectives were presented in various ways, such as in core competencies and achievement standards for science. As questioning was emphasized, teaching strategies and questioning appeared at a similar rate. Motivation and interest, misconceptions were linked to teaching strategies and questioning. In some cases, assessment items and assessment criteria were presented at each level, and various PCK components were linked to these two components. Components with relatively large differences among publishers were supplementary or in-depth concepts, inquiry in textbooks, instruction sequence and method, subject-specific strategies, and assessment items. From the results, the implications for the development of teacher's guides were discussed.

This study analyzes the results of a survey based on classes conducted in the field to understand the educational needs of learners, and reflects the elements necessary for SW education. In this study, various experimental elements according to learning motivation and learning achievement were constructed and designed through previous studies. As a survey applied to this study, experimental elements in three categories: Faculty Competences(FC), Learner Competences(LC), and Educational Conditions(EC) were analyzed by primary area and secondary major, respectively. As a result of analyzing CT-based SW education by area, the development of educational materials, understanding of lectures, and teaching methods showed high satisfaction, while communication with students, difficulty of lectures, and the number of students were relatively low. The results of the analysis by major were found to be more difficult and less interesting in the humanities than in the engineering field. In this study, Based on these statistical results proposes the need for non-major SW education to improve into an interesting curriculum for effective liberal arts education in the future in terms of enhancing learners' problem-solving skills.
