  • The Inquiry Activities the newly developed Korean High Schol Biology Textbooks were evaluated using SIEI(Seientific Inquiry Evaluation Inventory). The textbook evaluated are five Introductory Biology books and five Advanced Biology books developed in 1990. The instrument, SIEI, was developed by Myung Hur in his doctoral study at Columbia University in 1984. The major findings of the study are summarized below. 1. The inquiry activities in the textbooks are focusing on the low level science process skills 2. Students are rarely asked to formulate a hypothesis or to design an experiment. 3. The structure of the Inguiry Activities are mostly competitive, thus inhibiting the inquiry achievement of students. 4. The Inquiry Indices of the textbooks are between 14 and 16, meaning only 14 to 16 percent of the total instructional time are to be devoted to inquiry activities.

  • 7차 교육과정에 따라 개발된 7학년 과학교과서 물질 영역의 탐구활동을 분석하여 교과서의 개발과 학습에 대한 교육적 시사점을 찾고자 하였다. 교과서의 탐구활동을 탐구유형, 탐구과정, 탐구상황 등의 3개의 영역으로 나누어 분석하였다. 6개 출판사에서 발간된 과학교과서의 ‘물질의 세 가지 상태', ‘분자운동', ‘상태변화와 에너지'를 분석 대상으로 하였다. 7학년 물질 영역의 탐구 활동 분석 결과를 종합하였을 때, 탐구 유형이나 탐구 과정 요소 및 탐구 상황의 편중성이 두드러졌으며, 이러한 부분을 보완할 수 있는 탐구 활동으로 학생들을 지도하여야 할 것이다. 또한, 과학과의 교육 목표에 부합되는 교과서 개발을 위해 탐구 활동을 검토하고 교과서 검정 기준에 탐구 활동의 평가틀을 제공하여야 할 것이다.

  • The purpose of this study was to point out the problems of the competency exam for college education, a new college entrance exam, and to suggest the improvement ideas for it For this purpose, the test items of science inquiry were taken from the first, the second and the third pilot studies of the competency exam for college education which National Institute of Educational Evaluation had done. These tests were administered to 1,223 students of the general high school(422 for the 1st 400 for the 2nd, and 401 for the 3rd test). Also, those students' and the high school science teacher's opinions about the tests and the new college entrance exam were surveyed. The evaluation objectives of those test items were analyzed and the test item analyses were done. The results were as follows; (1) The evaluation objective analysis showed that most of the test The purpose of this study was to point out the problems of the competency exam for college education, a new college entrance exam, and to suggest the improvement ideas for it For this purpose, the test items of science inquiry were taken from the first, the second and the third pilot studies of the competency exam for college education which National Institute of Educational Evaluation had done. These tests were administered to 1,223 students of the general high school(422 for the 1st, 400 for the 2nd, and 401 for the 3rd test). Also, those students' and the high school science teacher's opinions about the tests and the new college entrance exam were surveyed. The evaluation objectives of those test items were analyzed and the test item analyses were done. The results were as follows; (1) The evaluation objective analysis showed that most of the test items were constructed based on the evaluation framework which was composed of scientific inquiry thinking ability, science concept, and scientific inquiry context dimensions. But, those items were unevenly distributed into a few areas of the evaluation framework. (2) The boys had higher mean scores than the girls in all of the tests, but these differences were not statistically significant. The natural science course students had significantly higher mean than the humanities course students in all of the test:(1st, F=12.643, p=0.0004 ; 2nd, F=45.757, p=0.0001 ; 3rd, F=36.162, p=0.0001). A significant interaction of sex and course was found in only 1st test( F=11.352. p=0.0008). (3) Most students answered the test was difficult and they needed more time to finish it Also, they added they had to study in a different way from the traditional one in order to prepare the new college entrance exam. Science teachers answered that those evaluation objectives of the tests corresponded well with the educational objectives of high school science and that the tests were suitable as measuring instruments of the scientific thinking abilities. But they pointed out it would be very difficult for them to teach students for preparing the exam under the exsting educational conditions. To carry out successfully the competency exam for college education, the following improvements were suggested. (1) Good evaluation methodology should be developed. (2) In-service science teacher training models on evaluation should be put in force. (3) Effective teaching models and strategies should be developed.(4) The high school science curriculum should be revised.
