The purpose of this study was to examine the relation between students' reflective thinking and providing the reading framework in implementation of argument-based inquiry using the Science Writing Heuristic (SWH) approach. Participants of this study were 60 $8^{th}$ grade students (two classes). One class (31 students) was assigned to an experimental group and the other class (29 students) was assigned to a comparative group. For the experimental group, five activities using the reading framework with SWH writing template were implemented, while three activities using the reading framework with the SWH writing template and two SWH activities without the reading framework were implemented for the comparative group. The result of this study showed that there was no significant difference in students' reflective thinking between both groups. However, results indicated that providing the reading framework with SWH approach facilitated students' reflective thinking. Therefore, the findings show that providing the reading framework consistently in the SWH approach was effective when it came to facilitating students' reflective thinking.

The purpose of this study is to review the foundation of the representative early scientific societies and their major activities. The documents, books, and literature related to this study were collected through internet websites (e.g., google scholar, wikipedia) and analyzed by the qualitative content analysis method. The result of this study shows that requirement for the necessary resources to acquire or to prepare the instruments for the experiment is significantly increased with the rising importance of the experiments to conduct the scientific methods. As a consequence, scientists faced urgent necessities to conduct scientific experiments with cooperation and exchange of the newest information by establishing a community beyond the independent and individual research activity. Establishment of the scientific societies is the result of these necessities. At the beginning of the scientific societies, the resources are provided by either wealthy patron or member contribution or public through foundation of government organization. This study provides the implications for future scientific societies.

본 연구는 방과 후 농업 체험활동 프로그램이 초등학생의 정서지능과 회복탄력성 향상 및 우울감 감소에 미치는 영향을 알아보고자 실시하였다. 서울시 초등학교에 재학 중인 4-6학년(11-13세) 초등학생 총 30명이 본 연구에 참여하였다. 참여에 동의한 30명의 학생 중 농업체험 프로그램에 참여를 희망한 18명은 실험군으로, 농업체험 프로그램에 참여를 희망하지 않은 학생 12명은 대조군으로 집단화 하였다. 실험군은 2018년 4월부터 7월까지, 총 12주간(주 1회, 회기당 60분)의 방과 후 활동으로 본 프로그램에 참여하였다. 초등학생의 정서적 건강 증진을 위해 사회정서학습 이론에 기반한 농업체험 프로그램을 설계하였다. 프로그램 실시 전과 후에 자기보고식 설문지를 이용해 정서지능, 우울, 회복탄력성을 측정하였다. 그 결과, 농업 체험활동 프로그램에 참여한 초등학생의 정서지능이 향상되었고(P=0.031), 우울감이 감소된(P=0.011) 반면 대조군에서는 유의한 차이가 나타나지 않았다(P>0.05). 회복탄력성은 실험군과 대조군에서 모두 실험 전후 유의한 차이가 없었다(P>0.05). 본 농업체험 프로그램에 참여한 아동들은 프로그램에 대해 높은 만족감을 보고하였다. 따라서 본 연구에서 사회 정서학습이론을 적용한 농업체험 프로그램이 초등학교 고학년 학생의 정서지능 향상과 우울감 감소에 효과적인 것으로 나타났다. 추후, 표본수를 확대하여 농업 체험활동 프로그램의 효과 검증 연구가 추가적으로 필요할 것이라 생각되며, 다양한 지역의 초등학생들에게 확대 적용하는 연구도 필요할 것이다.

In this study, we investigated the characteristics of the authentic inquiry components in the inquiry tasks of Science Inquiry Experiments textbooks developed under the 2015 Revised National Curriculum. After classifying inquiry tasks by core concepts, we analyzed the cases that students autonomously planned or performed the authentic inquiry components. The results of the study revealed that investigating multiple materials component most frequently appeared in all units. However, generating research question, selecting variables, observing multiple variables and transforming observations components appeared in a few tasks of history and everyday science units as they were often guided or structured in textbooks. Controlling simple or complex variables, observing intervening variables and considering methodological flaws components rarely appeared in all units as most of textbooks did not consider or indicate explicitly. Authentic inquiry components of everyday science unit tended to be handled in small group activities. On the bases of the results, the implications for the development of the inquiry tasks of Science Inquiry Experiments textbooks are discussed.
