과학영재 교수방법에 대한 초등과학 영재교사의 지식에 대한 사례연구
여상인 ( Sang Ihn Yeo ),진현숙 ( Hyun Suk Jin ) 경북대학교 과학교육연구소 2012 科學敎育硏究誌 Vol.36 No.1
이 연구는 세 명의 초등 과학영재 담당교사의 전문성을 영재교육 교수방법의 관점에서 알아보고자 한것이다. 세 명의 교사는 모두 영재교육연수를 이수하였으며, 주위로부터 영재교육 전문성이 높다고 추천을 받은 교사이다. 두 명의 교사는 영재교사 경력이 5년 이상이고, 한명의 교사는 영재교사 경력은 1년이나 교직경력은 11년이었다. 참여 교사의 수업지도안, 수업관찰, 교사면담을 통해 자료를 수집하였고, 모든 수업자료와 면담자료는 전사된 후 분석하였다. 연구결과 다음과 같은 몇 가지 특징을 보였다. 첫째, 교사들은 영재교육을 위한 여러 가지 교수-학습 모형은 인지하고 있었지만, 렌줄리의 3부 심화학습모형을 가장잘 알고 많이 활용하고 있었다. 둘째, 수업에 활용할수 있는 영재교육 프로그램에 대한 자원에 대하여 교사들은 주로 한국교육개발원에서 개발한 교수-학습자료에 대한 의존도가 높았다. 셋째, 교사들은 영재학생의 수준과 특성에 맞게 보급된 영재교육 프로그램들을 재구성하였지만, 실제 영재수업에서는 충분히 발현되지는 않았다. 연구 결과를 토대로 영재수업의 질을 높이기 위한 교수-학습 방안에 대한 시사점 등을 논의하였다. The purposes of this study is to identify the professional knowledge of the three elementary teachers for science-gifted students in teaching method. All teachers have received in-service program in gifted education, and have been recommended by their colleagues. Two teachers have instructed the gifted for more than five years, one teacher have instructed the gifted for one year and the general students for eleven years. For for this study, each teacher`s lesson plans were collected, videotapes were recorded during lessons, and in-depth interview for each participant were conducted. All recoded data were transcribed and analyzed. Some unique characteristics of teaching method for the gifted were identified from the class instruction of participants. They had knowledge of teaching model for the gifted, especially Renzulli`s three pod enrichment model. And they mainly used the materials developed by KEDI for the gifted. Also they had capability to be able to reconstruct them, but their lesson plans did not be realized well in their class. Some implications from findings of this study were suggested, such as teaching methods to improve the quality in the classes of the gifted in science.

In order to find out a proper connecting bridge between 5-fluorouracil(5-FU) and a macromolecule such as a polypeptide, potentially hydrolytic N1-derivatives of 5-FU have been synthesized and evaluated for their biological activity. When tested with in vitro leukemic L1210 cells all the obtained derivatives exhibited slightly higher antitumor activity than the parent 5-FU. Among them the N1-carbamoyl analogue 2 and N1-acetamido analogue 6b showed 50% inhibition of the L1210 Cell growth at the concentrations of 5.01 X 10-8M and 1.03 X 10-7M, respectively. When tested against sarcoma 180 tumor cells inoculated into mice, the compounds 2 and 6b exhibited, respectively, 62% and 54% inhibition of the solid tumor growth at the 5-time doses of 100 mg/kg/day. Both compounds, N1-carbamoyl analogue 2 and N1-acetamido analogue 6b, released the parent 5-FU when incubated in the L1210 cell cultural media for 5 hrs.

In order to find out a proper connecting bridge between 5-fluorouracil(5-FU) and a macromolecule such as a polypeptide, potentially hydrolytic N^1-derivartives of 5-FU have been systhesized and evaluated for their biological activity. When tested with in vitro leukmic L_1210 cells all the obtained derivartives exhibited slightly higher antitumor activity than the parent 5-FU. Among them the N^1-carbamoyl analogue 2 and N^1-acetamido analogue 6b showed 50% inhibition of the L_1210 cell growth at the concentrations of 5.01×10^-8 M and 1.03×10^-7 M, respectively. When tested against sarcoma 180 tumor cells inoculated into mice, the compounds 2 and 6b exhibited, respectively, 62% and 54% inhibition of the solid tumor growth at the 5-time doses of 100 ㎎/㎏/day. Both compounds, N^1-carbamoyl analogue 2 and N^1-acetamido analogue 6b, realeased the parent 5-FU when incubated in the L_1210 cell cultural media for 5 hrs.
