고차적 질문 생성 전략이 초등 과학 수업에 미치는 효과
배진호,김정아 韓國生物敎育學會 2008 생물교육 Vol.36 No.4
This research was conducted to find out what influences high-level questions-generated strategies have on the students' science learning characteristics by applying them to the 6th grade's science class units, "Comfortable Environment" and "Combustion and Extinction." This research could obtain the next three results. First, the high-level questions-generated strategies impressed academic achievement and adoption of the attitudes toward science lessons. Even though scientific inquiry skill and scientific attitudes do not show significant difference, their average points were higher after the instruction. Especially, 'Date Analysis', 'Hypothesis Foundation', 'Variables Control' and 'Generalization' factors under the scientific inquiry skill section and 'Life Esteem', 'Application', 'Criticism' and 'Openness' factors of the scientific attitudes section make difference. Second, 1,856 questions requested by the treatment group during 16 lessons demonstrate that they have positive contributions to facilitating critic and reasonable thinking. Besides, the ratio of high-level questions rather than low-level went up as the class was taken. Third, changes of academic achievement, scientific inquiry skill, scientific attitudes and the attitudes toward science lessons were significant in proportion to question level.
초등 예비 교사들의 전공심화과정에 따른 에너지 절약 관련 태도 및 행동에 대한 차이

본 연구에서는 초등 예비 교사들의 전공심화과정에 따른 에너지 절약 태도 및 행동에 대한 차이에 대해 조사하였다. 그 결과, 초등 예비교사의 에너지 절약 태도 점수는 초등학생의 에너지 절약 태도 점수보다 높게 나타났다. 에너지 절약 태도는 전공심화과정별로 유의미한 차이가 나지 않았으며, 에너지 절약 태도의 모든 하위 영역에서도 전공심화과정별로 유의미한 차이가 나지 않았다. 반면에 에너지 절약 행동 전체 평균 점수는 전공심화과정별로 이학계열, 예체능계열, 인문계열의 순으로 높게 나타났다. 또한 에너지 절약 태도의 점수와 비교해 볼 때 행동에 관한 평균 점수가 낮게 나타났다. 에너지 절약 행동에 관한 결과는 전공심화과정별로 유의미한 결과를 보였다. 특히 이학계열과 인문계열이 매우 유의미한 차이를 보였고, 이학계열과 예체능계열도 매우 유의미한 차이를 보였다.

In this study, I researched how the inquiry activity through plants results in scientific process skills, science attitude and observation skills for the elementary school students. For that, a comparative group and a experimental group are chosen. After inquiry activity through plants. I compared scientific process skills, science attitude and observation skills of experimental group with those of comparative group. This study showed the followings. 1. inquiry activity through plants is effective in scientific process skills in observation and classification. 2. inquiry activity through plants is successful in the attitude about science in understanding and interest for science. 3. inquiry activity through plants is also effective in scientific attitude in safety, straightforwardness and objectivity of scientific attitudes. 4. inquiry activity through plants is meaningful in observation skills in finding eifferent pictures.

N/A Effects of Si and Ni addition on the microstructure and mechanical properties of the Cu-12wt.%Al-5wt.%Fe-1wt.%Mn alloy have been investigated experimentally. Microstructure of the as-cast specimen is found to be refined markedly by additions of Ni and Si. By the addition of Ni, volume fraction of the k phase is increased, but volume fraction of the y phase is decreased. Hardness is increased with the addition of Ni, due to increasing of k phase which is harder than y phase. However, Charpy impact value is not significally decreased possibly due to the formation of isolate k phase. (Received February 19, 1998)

The purpose of this study was to identify the conception and misconception on the biological phylogenetic classification of the elementary students. For this study, the multiple choice and a subjective question of questionnaire consisted of 10 items on the biological phylogenetic classification was developed and administered to 158 elementary students. The results of this study are as follows : They have many trobles in conception of the phylogenetic classification between flowering plants and flowerless plants, dicotyledons and monocotyledons, sympetalous flowers and schizopetalous flowers, complete flowers and incomplete flowers.
