박헌우 ( Heon Woo Park ) 한국초등과학교육학회 2012 초등과학교육 Vol.31 No.4
The purpose of this study was to examine the effect of utilization of drawing skills in elementary science class on improving scientific drawing. The learning program has been developed for 5th grade students in the regular classes in order to enhance scientific drawing skills. The program was composed of three steps, understanding the kinds of drawing, imitating sample drawing, representing through observation. The developed program was verified by the science education scholars and teachers. Students trained during 3 hours with scientific drawing skills step by step. As a result, students significantly improved skills in scientific drawing skills. Furthermore, the effect was sustained after a month. On the other hand, there were no statistically meaningful differences on scientific attitudes and preferences.

Environmental education contents in science textbooks of South Korea and the United States were compared and analyzed in order to find how to develop environmental education in elementary science education. McGraw- Hill science textbooks for third to sixth grade and science textbooks of Korea based on the 2009 Revised National Curriculum and the 2007 Revised National Curriculum were analyzed and compared. The categories were educational goals, kinds of contents, distributions of contents and tense. The result showed that the environmental education goals in science textbook of Korea and United States were biased to knowledge area. The educational contents of the United States was higher 2.5 times then Korea and distributed in all areas. In quantitative distributions in Korea were biased some special areas. Tense of educational contents were almost present. Attitudes and recognition of students varies gradually over a long period of time, the contents of environmental education will be useful “evenly distributed” for all areas and school year.

In this study, we analyzed request methods and demanding levels of drawing activities in teacher`s guide and supplementary book (experimental observation). Student`s drawing results were also compared to teacher`s guide and supplementary books demanding. As a result, drawing activities of supplementary book were reached to 42.8% of all activities. Activity types were divided to writing, drawing, writing and drawing and writing or drawing activities. Writing and drawing activity type was 44.4%, and drawing activity was 37.8%. The level of teacher`s guide were higher than normal needs. But answer examples and learning levels of teacher`s guide were appropriate for curriculum levels. The students drawing activities were matched to requirements of the teacher`s guide to 72.3% in grade 3 level and 64.5% in 4th grade level. In order to improve effectively learning, statement of supplementary book and teacher`s guide should write more concrete words and creative sentences.
인천만의 검은머리갈매기(Larus saundersi) 번식개체군 변동

There are only 10,000 Saunders` Gull`s(Larus saundersi Swinhoe) surviving in the world today. But they are being threatened by coastal habitat, degradation, development pressure and disturbance by humans. Their first breeding record in Korea was in 1998 and the breeding status has been studied, however, the breeding status is not sufficient for this species. This study was performed from May 1999 to June 2009 to clarify breeding populations and trend of the Saunders` Gull population in Korea. The results indicate that the breeding population has been increasing gradually from 300 to 1,300 individuals, though disturbance increased. As threats to the breeding birds, physical environmental factors such as development and human disturbance were identified as a major threatening factors. Also, as a secondary factor, eggs and chicks are falling pray to predators. Incheon bay breeding places have been created by a landfill projects for the purpose of urban and industrial development, thus, these places will no longer be available for this species. In addition, the breeding habitat has been reduced and changed by expansions of development on the ground. Therefore, well planed management schemes should be provided for the species` breeding population to be continually breed and survive.

The purpose of this study is to examine if any effect on long-term life experience program made changes of science related attitude and environmental awareness. The subjects of this study were primary school sixth graders who live in Daejeon. The life experience program was composed of 21 activities over nine months from March to November, and each of the activities was to support students in life experience. As a result, the scientific attitude and the attitude toward science were a positive change, and the environmental awareness confirmed the significant changes in the entire region. It was concluded that long-term life ex-perience program had a positive effect on students`` science related attitude and environmental awareness. The long-term life experience program should continue to improve the science related attitude and environmental awareness of the students.
사진촬영을 이용한 벌매 (Pernis ptilorhynchus)의 형태적 다양성 및 이동 연구

조류의 깃털은 종을 동정하고 연구할 수 있는 형태학적인 정보를 제공하는 가장 기본적이고 핵심적인 특징이다. 그러나 이러한 정보는 표본이나 채집을 통해서만 가능하기 때문에 개체수가 적고 관찰이 어려운 수리과(Accipitridae) 조류나 해양성 조류에는 적용하기 어렵다. 수리과 조류는 먹이사슬의 최상위 포식자로 생태적 기능이 중요하다. 그러나 대부분 개체수가 적어 세계적으로 멸종위기에 처해 있어 보호와 관리가 필요한 분류군이다. 벌매(Pernis ptilorhyncus)는 시베리아 남부, 몽골 북부, 중국 동북부 및 일본에서 번식하고 남쪽에서 겨울을 지내는 종으로 조류의 이동 행동 및 진화 생태를 연구하기에 적합하고 매력적인 분류군이다. 우리나라에서 관찰되는 벌매는 특정시기에 대규모 개체군을 형성하여 바다를 건너 번식지와 월동지를 이동하는 생태적 특징을 가지고 있다. 또한, 깃털이 다양한 변이가 있어 성별, 유조와 성조 등의 개체 구분이 가능한 분류군이다. 벌매에 대한 연구는 대부분 이동기 개체군 규모 및 이동경로에 대한 연구와 우리나라 번식사례 연구가 대부분이다. 벌매의 보호와 관리를 위해서는 해마다 어느 정도의 성조와 유조가 이동을 하는지와 깃털의 형태적 다양성에 대한 정보 그리고 이에 대한 다양한 연구방법의 개발이 필요하다. 본 연구는 2014년부터 2016년까지 3년간 가을철 소청도를 통과하는 벌매를 대상으로 개체 단위로 촬영된 사진 분석방법을 이용하여 개체군의 형태적 다양성과 성별, 연령별 이동 특성을 알아보기 위하여 실시되었다. 촬영된 1,366개체의 벌매를 분석한 결과 2년생 이상 성조는 전체의 15.37%이었고, 당해 태어난 유조는 83.6%로 대부분 유조가 통과하는 것으로 나타났다. 성조 암수 비율에서는 수컷이 11.79%, 암컷이 3.58%로 수컷이 3배 정도 많았다. 이동 시간대는 암컷 성조와 유조는 10시~11시와 13~16시 사이에 주로 이동하여 유사한 패턴을 보였으나 수컷 성조는 10~16시까지 꾸준히 이동하였다. 조사된 개체수 분석결과 암컷 성조, 수컷 성조, 유조 간 통계적 유의미한 차이가 있었다(two-way ANOVA test, F=32.266, df=2, p<0.05). 깃털의 형태적 다양성 분석에서는 수컷 성조는 적갈색형(red-brown morph)이 39.13%, 중간형(intermediate morph)은 36.02%이었고, 암컷 성조는 적갈색형이 48.98%, 중간형은 20.14%의 비율로 나타났다. 유조의 경우 깃털의 형태적 다양성 비율은 통계적 유의한 차이가 없었으나 연구기간에 따라서는 유의미한 차이가 있었다(two-way ANOVA test, F=0.8, df=2, p<0.05). 조류에 있어서 동일한 종 내에서 깃털의 형태적 다양성을 보이는 이유는 성 선택과 더불어 다양한 행동, 생리 및 생활사 특성과 관련한 다양한 적응 기능을 제공하는 것으로 알려져 있다. 본 연구는 사진촬영 분석방법을 이용하여 소청도를 경유하여 이동하는 북동시베리아 벌매집단의 형태학적 다양성을 규명하고, 연령과 시간대별 이동 양상에 관한 정보를 확보한 첫 연구사례이다. The Oriental Honey-buzzard Pernis ptilorhyncus, which breeds in the areas of southern Siberia, northern Mongolia, northeastern China, Korea and Japan, and that migrates south for winter is a suitable and attractive subject for studying the behavioural and evolutionary ecology of bird migration. In this study, we investigated the morphological diversity, sex, and age - related characteristics of the Oriental Honey-buzzard populations using photographic analysis methods as they pass by Socheong island in autumn from 2014 to 2016. According to the study of analyzing 1,366 individual birds, 15.37% of the birds were more than 2 years old and 83.6% of the birds were juveniles. The sex ratio was 11.79% for males and 3.58% for females. Males were three times more than females. At the time zone of migration, females adult and juveniles migrated at 10 to 11 and 13 to 16 o’clock while male adults continued to move 10 to 16 o'clock. In the analysis of populations, there was a statistically significant difference between females, males and females(two-way ANOVA test, F=32.266, df=2, p<0.05). The morphological diversity analysis showed that 39.13% of red-brown morphs and 36.02% of intermediate morphs were males. And females were 48.98% reddish brown and 20.14% middle females. However, in the case of juvenile, the morphological diversity ratio of the feathers was not statistically significant, but there was a significant difference according to the study period(two-way ANOVA test, F=0.8, df=2, p<0.05). This study was the first case to identify the morphological diversity of oriental honey buzzard populations using photographic analysis methods. As the same time, it was the first study to confirm the information on the age and time-based mobility patterns.
