The purpose of this study was to analyze the responses and the behavioral characteristics between mathematically promising students and normal students in solving open-ended problems. For this study, 55 mathematically promising students were selected from the Science Education Institute for the Gifted at Seoul National University of Education as well as 100 normal students from three 6th grade classes of a regular elementary school. The students were given 50 minutes to complete a written test consisting of five open-ended problems. A post-test interview was also conducted and added to the results of the written test. The conclusions of this study were summarized as follows: First, analysis and grouping problems are the most suitable in an open-ended problem study to stimulate the creativity of mathematically promising students. Second, open-ended problems are helpful for mathematically promising students' generative learning. The mathematically promising students had a tendency to find a variety of creative methods when solving open-ended problems. Third, mathematically promising students need to improve their ability to make-up new conditions and change the conditions to solve the problems. Fourth, various topics and subjects can be integrated into the classes for mathematically promising students. Fifth, the quality of students' former education and its effect on their ability to solve open-ended problems must be taken into consideration. Finally, a creative thinking class can be introduce to the general class. A number of normal students had creativity score similar to those of the mathematically promising students, suggesting that the introduction of a more challenging mathematics curriculum similar to that of the mathematically promising students into the general curriculum may be needed and possible.

The purpose of this study is to explore the changes caused by using smart technology in school science inquiry. For this, we investigated 12 elementary school teachers' perceptions by using an open-ended questionnaire, group discussions, classroom discussions, and participant interviews. The results of this study indicate that the introduction of technology into classroom inquiry can open up the various possibilities and can cause additional burdens as well. First, teachers explained that smart technology can expand the opportunities to observe natural phenomena such as constellations and changing phases of the moon. However, some teachers insisted that, sometimes, learning how to use new devices disrupts students' concentration on the inquiry process itself. Second, teachers introduced the way of digital measurement using smart phone sensors in inquiry activities. They said that digital measurement is useful in terms of the reduction of errors and of the simplicity to measure. However, other teachers insisted that using new devices in classroom inquiry can entail additional variables and confuse the students' focus of inquiry. Communication about inquiry process can also be improved by using digital media. However, some teachers emphasized that they always talked about both the purpose of using SNS and online etiquettes with their students before using SNS. Based on these results, we discussed the necessity of additional analysis on the various ways of using digital devices depending on teachers' perceptions, the types of digital competency required in science inquiry using smart technology, and the features of norms shaped in inquiry activities using smart technology.

The main purpose of this study is to examine the effects of explicit instructions on the nature of science (NOS) on the understanding of science-gifted students. Participants were engaged in 8 explicit NOS instructions spanning 6 months. Data were collected before and after the instructions from 20 science-gifted students using student worksheets, open-ended questionnaires (Views of Nature Of Science, VNOS), and in-depth interviews. The results of this study showed that explicit instructions were helpful in improving the understanding of the tentativeness in science and socially and culturally embedded aspects of science. However, participants not only still possess naive views on the nature of science about the distinction of law and theory and the empirical aspects of science, but also had conflicting views and misconceptions in some areas. The study has implication for development of science-gifted program that the explicit instructions on NOS and science inquiry should be provided concurrently, given the complementary relationship of the two activities.

본 연구는 우수한 학업 성적을 보이는 재미 한인 영재 청소년들이 민족적 정체감을 어떻게 형성해 나가는지를 알아보는데 그 목적이 있다. 이를 위해 미국 뉴욕의 학업영재아를 위한 고등학교에 재학중인 25명의 한인 영재아들을 대상으로 Phinney의 민족적 정체감 평가지가 사용되었다. 민족적 정체감의 평가를 위해 3가지의 민족 정체감 구성요인들이 사용되었는데, 이들은 민족적 자기 정의, 민족집단에 대한 평가와 민족집단에 대한 참여이다. 개방형 문제에 응답을 한 학생들은 두 명의 독립적인 관찰자에 의해, 자신이 정의한 민족집단에 대한 탐구와 헌신의 정도에 따라, 3단계의 민족 정체감 발달 단계로 나누어졌다. 이 3단계 중 첫번째 단계는 자신이 속한 민족집단에 대한 무관심과 낮은 참여도를 보이는 민족 정체감 무관심의 시기이고, 두 번째 단계는 자신의 민족집단에 대한 관심을 가지고 그 집단의 역사와 철학, 문화, 그리고 주류사회 속에서 해당 민족집단의 사회적 위치와 편견 등에 대해 관심과 참여를 보여주는 민족 정체감 탐구의 시기이며, 마지막 단계는 민족 정체감 완성 시기로, 자신을 그 집단의 구성원으로 완전히 수용하면서, 민족적 정체감에 안정된 모습을 보이는 단계이다. 각 민족 정체감 구성요소들과 민족 정체감 발달 단계내의 집단차를 논의하기 위해 ANOVA가 사용되었다. 연구에 참여한 대부분의 영채아들은 자신을 재미아시아인이 아니라, 한국인 혹은 재미동포로 정의하였고, 이러한 민족적 자기 정의는 학생들의 민족집단에 대한 평가도와 참여도에 중요한 역할을 한다는 것을 알 수 있었다. 또한 민족집단에 대한 긍정적인 평가는 민족집단에 대한 활발한 참여와 밀접한 관련성을 가지고 있었다. 연구에서 나타난 결과들을 바탕으로 재미 한인 영재 청소년들이 높은 자아 존중감을 지닐 수 있도록, 현재 교육현장과 실생활에서 활용할 수 있는 여러 방안들과 함께, 앞으로 필요한 보다 많은 연구를 위한 제언이 제시되었다. 사고력 계발에 보다 충실할 수 있도록 내용의 폭을 넓히고 접근방법을 달리하는 심화 중심으로 교육과정을 구성하고 운영한다고 하였다. 그러나 현재 개발된 교육과정 편성과 운영은 창의성 교육의 구현보다는 압축형 속진 교육과정의 특성이 강하여, 이와 같은 운영지침을 실현하기 어려운 것이 현실이므로 교육과정 편제의 개선이나 운영지침에 적합한 교육내용의 개발이 시급히 이루어져야 할 것이다. 둘째, R&E(Research ＆ Education)는‘연구를 통한 교육’,‘교육을 통한 연구’를 의미하며 과학영재교육과정의 가장 큰 특징이라 할 수 있는 자율연구와 위탁교육을 위한 프로그램이다.여주는 것으로 나타났다.보였다. 5.

The modern society is rapidly changing, and accordingly, the required teacher image is changing as well. Middle school students are immature, when they undergo major changes both physically and mentally, and teachers have a great influence. How students perceive the teacher determines the relationship between teachers and students. Therefore, it is necessary to analyze what kind of teacher image middle school students want. The purpose of this study is to analyze the image of a science teacher who prefers and avoids each class situation perceived by middle school students. To this end, 502 middle school students were divided into five classes: class type, class material presentation method, subject instruction method, subject content explanation method, and class atmosphere, and the image of science teacher who prefers and avoids is described in an open format. Concepts presented by middle school students were analyzed through semantic network analysis (SNA). The conclusions of this study are as follows: first, in order to make middle school students interested in science, an inquiry-centered experiment class should be conducted. Second, the change of class by science teacher can change it into preferred science class. Third, student-centered classes should be conducted according to the level so that students can understand. Finally, science teachers continue to strive through communication between science teachers and students, and students and students, and look forward to changes in science classes through this.
