참과학과 자연 연결의 측면에서 자연기반학습의 의미 탐색을 위한 실행 연구
형시리,주은정 한국생물교육학회 2022 생물교육 Vol.50 No.2
The purpose of this study is to show how nature-based learning gives meaning to authentic science and nature connection. For the study, nature-based learning based on plant-related units was applied to 4th-grade students in elementary school. In the learning process, a qualitative analysis was conducted to find out how students learn science in terms of authentic science and how it is connected to nature. Student in nature was closely observed and students' behavior and conversations were collected through the teacher diary and students' activity sheets based on observations. And after nature-based learning, a questionnaire was prepared and interviewed students. The data were conceptualized by classifying the data into keywords according to the subject and classified according to the subject using typological analysis. In the results, while experiencing nature as a context of learning, students in nature were interested in science and were connected to active participation. In addition, the students focused on the learning topic and helped them understand and remember what they learned. Nature-based learning provided opportunities for communication and problem-solving and experienced authentic science based on the context in the real world as nature was connected to daily life. Through their experiences in nature, students experienced the enjoyment of nature and empathy and preciousness for creatures. This experience helped connect students with nature, and furthermore, students thought about the relationship between nature and themselves and expressed a sense of responsibility for life.

Only the habitat characteristics and breeding status of Paridae have been studied, in addition to the lack of research on Parus varius varius, there is no study on the home-range in the post fledging period. This study was analyzed the home-range size of Parus varius varius in the post fledging period. The survey was conducted in the site located in Dankook Univ. Cheonan Campus(Middle Chungcheong Province). We captured five newborn Parus varius varius using artificial nest was installed before. Radio-tracking was carried out for analysis of home-range, and MCP (Minimum Convex Polygon) was used for analysis. We analyzed 1 individual tracked 15 days (VT5) and 4 individuals which missing radio-tracking transmitter within 3 days (VT1~VT4). Home-range of VT5 gradually increased to 1,38ha, 1.42ha, 2.14ha in the order of early, middle, late period. On the other hand, moving distance was decreased to 174.558m 125.129m, 120.180m. Home-range of V1~VT4 was estimated as 0.81ha which was 75.3% share of home-range of VT5 in early period. As the result it was found that home-range is formed far apart from artificial nest that has been influenced by human being interference, thereafter gradually adapting to interference and spreading close to artificial nest. through this research, we can construct basic ecological data for protecting habitat of Parus varius varius and increasing life rate. As first radio-tracking study of Parus varius varius home-range in the post fledging period, it is expected to be useful for the future study of home-range.

The problem of the population number of honeybees that is decreasing not only domestically but also globally, has a great influence on human beings and the entire ecosystem. The habitat of honeybees is recognized to be superior in urban environment rather than rural environment, and predicting for habitat assessment and conservation is necessary. Based on this, we targeted Cheonan City and neighboring administrative areas where the distribution of agricultural areas, urban areas, and forest areas is displayed equally. In order to predict the habitat preferred by honeybees, we apply the Maxent model what based on the presence information of the species. We also selected 10 environmental variables expected to influence honeybees habitat environment through literature survey. As a result of constructing the species distribution model using the Maxent model, 71.7% of the training data were shown on the AUC(Area Under Cover) basis, and it was be confirmed with an area of 20.73% in the whole target area, based on the 50% probability of presence of honeybees. It was confirmed that the contribution of the variable has influence on land covering, distance from the forest, altitude, aspect. Based on this, the possibility of honeybee`s habitat characteristics were confirmed to be higher in wetland environment, in agricultural land, close to forest and lower elevation, southeast and west. The prediction of these habitat environments has significance as a lead research that presents the habitat of honeybees with high conservation value of ecosystems in terms of urban space, and it will be useful for future urban park planning and conservation area selection.
