  • The analysis targeted the curriculum of general, subject education, and apecial activities that are required for SW education of 11 universities of education where SWEET project is applied. The results showed that the average credits related to SW education in elementary school teacher training institutions were 2.2 for general, 2.3 for subject education, and 0.6 for special activities. As a result of analyzing the changes in the curriculum by year, it can be interpreted as an effect of the SWEET project because the proportion of credits and hours in subject education increased and because the proportions of general and special activities decreased. However, on average, the credit related to SW education was 5.1, whereas the credits related to mathematics and science were 6.5 and 7.8, respectively, which indicated a need for revising and improving the curriculum for SW education.

  • 오늘날 지식정보사회에서는 국가의 과학기술이 그 나라의 국가 경쟁력을 좌우하게 되기 때문에 우수한 잠재력을 가진 영재를 조기에 육성하고 교육하는 일은 매우 중요하다. 특히 요즘처럼 지식정보사회로의 전환이 급속도로 진행되고 있는 현실을 고려해 볼 때에 영재교육 중 정보과학영계교육의 중요성은 더욱 커지고 있다. 사람들은 흔히 '영재'라는 이유로 기초가 되는 부분을 소홀히 하고 넘어가는 경우가 많다. 정보과학영재를 위한 교육과정 중 기초기술소양교육도 마찬가지였다. 대부분 프로그래밍 같은 고급기술을 요하는 것만 중시하지 워드프로세서나 프리젠테이션 프로그램 활용 같은 컴퓨터 사용에 기본이 되는 것들은 간과하고 넘어가는 경우가 맡았다. 하지만 기초가 단단해야 튼튼한 건물을 지을 수 있고, 뿌리가 깊어야 바람에 안 흔들리듯이 정보과학영재를 위한 교육과정 중 기초기술소양교육의 중요성은 무시할 수가 없다. 특히 컴퓨터에 대한 강한 호기심과 높은 창의력 등 정보과학영재로써의 많은 것을 갖추고 있지만 단지 기초기술이 부족한 아동은 정보과학영재가 아니라고 단정지어 말 할 수가 없기 때문에 기초기술소양교육은 매우 필요한 것이다. 따라서 본 논문에서는 정보과학영재교육의 필요성과 초등정보과학영재를 위한 기초기술소양교육의 필요성을 생각해 보고, 현재 일반적으로 이루어지고 있는 기초기술소양교육을 분석해 보고 단편적인 기능이 중심이 아닌 문제 해결 중심의 새로운 기초기술소양교육방안을 제시하고자 한다.

  • This study was expected to yield the meaningful conclusions from the experimental group who took lessons based on inductive activities using GeoGebra at the beginning of proof learning and the comparison one who took traditional expository lessons based on deductive activities. The purpose of this study is to give some helpful suggestions for teaching proof to mathematically gifted elementary students. To attain the purpose, two research questions are established as follows. 1. Is there a significant difference in proof abilities between the experimental group who took inductive lessons using GeoGebra and comparison one who took traditional expository lessons? 2. Is there a significant difference in proof attitudes between the experimental group who took inductive lessons using GeoGebra and comparison one who took traditional expository lessons? To solve the above two research questions, they were divided into two groups, an experimental group of 10 students and a comparison group of 10 students, considering the results of gift and aptitude test, and the computer literacy among 20 elementary students that took lessons at some education institute for the gifted students located in K province after being selected in the mathematics. Special lesson based on the researcher's own lesson plan was treated to the experimental group while explanation-centered class based on the usual 8th grader's textbook was put into the comparison one. Four kinds of tests were used such as previous proof ability test, previous proof attitude test, subsequent proof ability test, and subsequent proof attitude test. One questionnaire survey was used only for experimental group. In the case of attitude toward proof test, the score of questions was calculated by 5-point Likert scale, and in the case of proof ability test was calculated by proper rating standard. The analysis of materials were performed with t-test using the SPSS V.18 statistical program. The following results have been drawn. First, experimental group who took proof lessons of inductive activities using GeoGebra as precedent activity before proving had better achievement in proof ability than the comparison group who took traditional proof lessons. Second, experimental group who took proof lessons of inductive activities using GeoGebra as precedent activity before proving had better achievement in the belief and attitude toward proof than the comparison group who took traditional proof lessons. Third, the survey about 'the effect of inductive activities using GeoGebra on the proof' shows that 100% of the students said that the activities were helpful for proof learning and that 60% of the reasons were 'because GeoGebra can help verify processes visually'. That means it gives positive effects on proof learning that students research constant character and make proposition by themselves justifying assumption and conclusion by changing figures through the function of estimation and drag in investigative software GeoGebra. In conclusion, this study may provide helpful suggestions in improving geometry education, through leading students to learn positive and active proof, connecting the learning processes such as induction based on activity using GeoGebra, simple deduction from induction(i.e. creating a proposition to distinguish between assumptions and conclusions), and formal deduction(i.e. proving).

  • The purpose of this study is to develop the syringe experiment device which is able to analyze the relationship between the length of the air pillar and resonance frequencies quantitatively for the education of sound resonance. We made an air pillar resonance device with a 'Head', which is used by the disposable syringe and the plastic sphere for constructing molecular models. We also assembled PC experiment equipment which is used by commercial software. As a result, it appears this equipment can be used instead of the current device used by experts. It was proved that this syringe device is not the 'pipe' but the 'Helmholtz resonator'. It appears that data through resonance experiments can prove the sound resonance phenomenon. In conclusion, this syringe resonator is the experiment device that can be used in the gifted education for middle-high school students and acoustic experiments for university students.

  • This study used the text mining method to analyze the research trend of the Journal of Creative Information Culture(JCIC) which is the journal of convergence. The existing research trend analysis method has a limitation in that the researcher's personality is reflected using the traditional content analysis method. In order to complement the limitations of existing research trend analysis, this study used topic modeling. The English abstract of the paper was analyzed from 2015 to 2019 of the JCIC. As a result, the word that appeared most in the JCIC was "education," and eight research topics were drawn. The derived subjects were analyzed by educational subject, educational evaluation, learner's competence, software education and maker culture, information education and computer education, future education, creativity, teaching and learning methods. This study is meaningful in that it analyzes the research trend of the JCIC using text mining.
