The aim of this study was to investigate the patterns of the elementary school students' interests to animals and plants based on affinity toward animals and plants, and curiosity about animals and plants by using a cluster analysis. In addition, the differences of the big five personality traits by the identified clusters was examined. A total number of 411 elementary school students participated in the study. The students were clustered into four distinct interest groups with respect to the level of interests to animals and plants. Cluster 1 'Developed Interest to Organisms group' showed high levels in the interest to both animals and plants. Cluster 2 'Developed Interest to Animals group' showed high interest to animals and relatively low interest to plants whereas cluster 3 'Developed Interest to Plants group' showed high interest to plants and relatively low interest to animals. Lastly, cluster 4 were identified as 'Lack of Interest to Organisms group' by showing low levels of interest to both animals and plants. The four identified groups also showed different distributions of students according to gender and school year. These results support gender difference in the interest to animals and plants and suggest the decreased and specialized interest with school year. The Big Five personality traits excluding neuroticism were positively related with the interest to organisms and the identified groups showed significant differences in the traits. These findings indicate that agreeableness, conscientiousness, extraversion, and openness can be significant predictors of the interests to animals and plants.

The purpose of this study was to analyze the responses of pre-service elementary teachers to the plant learning using plant-observation activities and observation journal writings. Thirty pre-service teachers participated in this study. Before and after practicing plant observation and observation journal writing for 11 weeks, pre-service teachers' interest to plants, attitude to plant-observation teaching, and plant-observation teaching efficacy were examined using a questionnaire. Also, the observation journals, reflective journal writings, and interviews were analyzed to investigate their qualitative change. In addition, the pre-service teachers were classified by multi-dimensional scaling and cluster analysis with respect to attitude to plant-observation teaching and observation journal writing, and teaching efficacy. While the pre-service teachers showed significant increase of the interest to plants and plant-observation teaching efficacy, and positive change of the attitude to plant-observation teaching, there was a little difference between gender with more positive effects on females. The positive attitude changes of pre-service teachers included positive recognition about plants and the diversity, increased interest and curiosity about plants, careful observation about nearby plants, and independent learning and positive inquiry with plants. In terms of teaching efficacy, they showed positive change such as enjoyment and satisfaction with plant-observation, confidence as elementary teachers in the future, and recognition about the importance of elementary teachers for plant education. However, the changes were different among the groups classified by attitude to plant-observation teaching and observation journal writings, and plant-observation teaching efficacy.

Background and objective: The concept of 'money' in the numbers and operations domain is a fundamentally necessary domain of economic life. This study was conducted to examine the effects of a horticulture-mathematics integration program on mathematical attitude and money calculating ability of high school students with intellectual disabilities. Methods: We analyzed the changes in the mathematical attitude and money calculating ability of students with mild intellectual disabilities in S special school in the city of D, Republic of Korea, with 12 students in the control group and 12 students in the experimental group, from August 27 to October 29, 2019. Results: The results of the comparison showed no statistically significant changes in the three items of mathematical attitude for the control group, while the experimental group, which took part in the horticulture-mathematics integration program, showed statistically significant differences across all three items, such as self-concept about the subject (p = .003), attitude toward the subject (p = .004), and study habit related to the subject (p = .012). The horticulture-mathematics integration program, which was developed by integrating horticultural activities and the mathematics curriculum, used plants and horticultural activities to provide students with positive experiences in mathematics. These included the sense of closeness, curiosity, interest, attention, and enjoyment, leading to positive changes in mathematical attitude. In terms of money calculating ability, both the control group and experimental group showed statistical differences across the three items, but the experimental group showed greater degrees of increase, 15.0 or more, in the scores compared to the control group. Conclusion: These results suggest that utilizing horticultural materials as a part of purchase learning programs with elements of money calculation chapters in the mathematics curriculum could lead to the improvement of students' ability in money calculation. These positive changes are thought to be related to the high degrees of interest in horticulture among students, which led to active participation in the program and enabled the simple and repeated purchase activities in the program to generate positive changes in the money calculation ability of the students.

위대한 철학자이자 미적분을 발견한 수학자로 잘 알려진 라이프니츠(Gottfried Wilhelm Leibniz, 1646~1716)가 인삼에 대해 물었다는 사실은 거의 알려져 있지 않다. 유럽의 계몽주의를 열었던 라이프니츠는 왜 인삼에 관심을 가지게 되었을까? 이 글은 라이프니츠가 남긴 방대한 기록 속에서 인삼을 찾아내고, 개인적 생애와 당대의 지적 흐름을 엮어 그가 인삼에 관심을 갖게 된 경로를 추적한 작업이다. 16세기부터 유럽에서는 약물지와 같은 고대 그리스 텍스트의 재발견과 해외에서 들여온 새로운 식물들로 인해 본초학이 크게 발달하게 되었다. 같은 맥락에서 '구대륙' 중국에서 만병통치약으로 이름을 떨치던 인삼 또한 여행기 등을 통해 유럽에 소개되기 시작했다. 중상주의 기치 하에 유용한 약용식물에 대한 관심이 커 가던 유럽에서는 과학단체들을 중심으로 본격적으로 인삼에 대한 연구가 시작되었다. 라이프니츠는 그런 연구의 중심지였던 왕립학회와 프랑스 왕립과학원을 방문하고 학자들과 교류를 나누었으며 독일에 그와 같은 연구기관을 설립하는 것을 평생의 목표로 삼았다. 라이프니츠는 로마를 방문했을 때 예수회 선교사들과 긴밀하게 교류하는 기회를 갖게 되었다. 그 과정에서 중국에 대한 지적 호기심이 한층 더 깊어갔고, 그 맥락에서 인삼에 대한 관심도 커갔다. 라이프니츠는 그리말디, 부베 등 중국선교에서 핵심적인 활동을 했던 학자들과 인삼의 효능에 대한 정보를 주고받게 된다. 이 논문은 유럽의 계몽주의에서 전혀 주목받지 못했던 인삼이 17세기 말 유럽의 학문적 지형과 지식인들 사이의 교류, 중상주의적 해외팽창을 얽어내는 단초가 될 수 있음을 제시한 것이다.
