To achieve effective learning, knowledge must be shared and developed through interaction with peer learners. Therefore, science education emphasizes small group inquiry activities that solves tasks through the interaction of members. The effect of small group inquiry activities depends on how to compose small groups. The way in which a group is composed is a very important factor for improving interaction. In particular, it has been reported that the gender of peer is a very important factor in the interaction between students in the composition of small groups. Meanwhile, studies are being conducted on the types and stability of verbal interactions in small group inquiry activities using social network analysis. The purpose of this study is to analyze the types and stability of verbal interaction types and stability according to gender-grouping in elementary school students' small group activities using social network analysis. To this end, 60 5th graders in elementary school were conducted with different gender in the composition of the group of male, female and mixed-gender students. The study found that the composition of a group by gender had little impact on the type or stability of verbal interaction. However, the frequency of verbal interactions was higher in mixed-gender groups than in other groups. Through this process, the gender-grouping in elementary school students' small group activities suggests a mixed-gender group.

본 연구의 목적은 학업 성취가 매우 뛰어난 우리나라 고등학생들이 이공계 진로를 선택하거나 또는 선택하지 않는 이유를 설명하며 성별차를 탐구하는 것이다. 과학고등학교와 국제고등학교에 재학 중인 1학년 학생들이 참여하여 과학 활동, 과학 학습을 위한 자신의 강점, 과학 전공을 선택하거나 선택하지 않는 이유를 묻는 개방형 문항에 응답하였다. 학업성취가 뛰어난 고등학생들의 과학 전공 선택 이유로서는 내적 흥미가 가장 비중이 크며 다음으로 자기효능감의 비중이 큰 것으로 드러났다. 그러나 과학을 전공으로 선택하지 않으려는 것에는 흥미의 부족보다는 자기효능감의 부족이 더 큰 관련이 있는 것으로 드러났다. 이 외에 과학 학습에 대한 자아개념과 정규 수업 외의 과학 활동을 분석하고 비교하였으며 교육적, 정책적 시사점들을 논의하였다.

The purpose of this study was to know that the 'Thinking Science' activities affects the enhancement of critical thinking skill by the logical thinking skill about pupils in the $5^{th}$ and $6^{th}$ grade of elementary school in Korea. The 19 activities of 'Thinking Science' as the teaching materials was implemented to 40 pupils in elementary school over 13 weeks. Results indicated that the experimental group presented statistically meaningful improvement in logical thinking skills(p<.05). Those teaching materials contributed to improve 3 logical sub-elements significantly(p<.05) as the proportional logical element, the probabilistic logical element, and combinational logical element. But, there was no significant improvement in conservational logical element, control of variable element, and correlational element(p<.05).

In this research, the change of Korean middle-school science education environments is investigated through analyzing eighth graders' survey data collected over the past 20 years of TIMSS. We extracted educational context variables that provide meaningful information on changes of Korean science education, and have been surveyed more than 3 study cycles up to TIMSS 2015. The selected educational context variables include school resources and school climate from the school principal's questionnaires, and teacher characteristics and instructional activities from the teacher's questionnaires. For each context variable, we analyzed its trend over TIMSS cycles, and discussed its implications in light of Korean educational policy and curriculum changes. Based on the results, we recommended several ways that help to improve science teaching and learning in light of lab assistants, computer availability, teacher learning community, and middle school Earth science curriculum.

본 연구에서는 2009개정 교육과정의 중학교 과학교과서에 포함된 탐구 활동이 기존 과학교육에서 강조되어왔던 탐구 기능과 구체적 학생 활동이 강조되는 NGSS의 8가지 과학 실천 측면에서 상호 분석되었을 때 어떤 특성을 나타내는지 생명과학 단원을 중심으로 분석하였다. 분석 결과 학년 구분 없이 탐구 기능에서는 '추리', 관찰', '분류' 순으로 많이 치중되었고, 과학 실천에서는 '자료 분석하고 해석하기'와 '설명구성하고 문제해결 고안하기'에 치우쳐 있었다. 이를 통해 중학교 교과서 내 생명과학 탐구 활동이 탐구 기능뿐만 아니라 과학 실천 요소에서도 다양성이 부족하며 제시하는 활동의 목표가 한정적이라는 것을 보여주었다. 또한 과학탐구 기능과 과학 실천 요소 각 상호 매칭작업을 통해 탐구 기능 중심에서 과학 실천으로의 이행 시 내용 관련성을 검토하고 교과서의 탐구 활동에서 보이는 결과와 비교 분석한 결과 사전 매칭분석에 비해 교과서 내 탐구 활동의 결과가 대체적으로 기초탐구-자료해석/기초탐구-설명고안에 치우쳐 있어서 단조롭게 매칭 되었다. 이는 교과서에 제시된 활동내용의 다양성이 부족함을 보여주는 결과라고 할 수 있다. 본 연구에서는 2009개정 교육과정의 교과서 분석을 통해 단순하고 다양성이 부족한 탐구 활동에서 벗어나 2015개정 교육과정을 구현해나가는 과정에 다양한 과학 실천 요소를 포함시키도록 하는 노력이 절실하게 요구됨을 제언한다.

90년대는 일본 학생들의 문자이탈 현상 및 그에 따른 독해력 저하가 심각한 사회 문제로 대두되었던 독서의 위기 상황이었다. 그러나 이러한 상황을 전환점으로 삼아 학교도서관 및 관련 기관들은 관련 법률을 제정 개정 하고, 학교도서관 및 독서관련 사업을 펼치는 등 다양한 방면에서 어린이 독서활동의 환경 정비에 주력하였다. 본 연구에서는 90년대부터 활발하게 진행된 학교도서관을 둘러싼 독서환경 정비를 위한 각계각층의 노력들을 소개하고 정리함으로써 일본 학교도서관의 거시적 환경을 이해하고 한국의 학교도서관이 나아가야할 방향을 제고한다.

The purpose of this study is to discover and develop any implications which may arise in relation to science teachers' professional growth and development by investigating the difficulties experienced by elementary school teachers in science classes. 196 elementary school teachers were requested to write an anecdotal report regarding their science lessons. 30 science teachers in middle school also answered the same questionnaire. By means of inductive categorical analyzing, the difficulties were grouped into several categories. The results were as follows: (1) The difficulties elementary teachers experience in their science lessons fall into three categories; 'professional science knowledge(9.8%)', 'science laboratory activities(78.3%)', 'teaching methodology(11.2%)'. (2) Science teachers in middle school experienced similar difficulties. However, distribution differed from that of elementary school teachers; 'professional science knowledge(39.0%)', 'science laboratory activities(35.6%)', 'teaching methodology(27.1%)'. (3) The causes of these difficulties were identified as follows; a lack of time to prepare for science classes, insufficient substantial pre-service teacher education, and a lack of adaptive support to elementary school teachers.

The purpose of this study was to compare the configuration changes of content elements and inquiry activities between 2009 and 2015 revised national elementary school science curriculum, and to examine the trends in achievement standards. The results of this study were as follows. First, the number of content elements presented in the 2015 revised science curriculum was slightly decreased in comparison to 2009 revised one, but fell short of goal level for revision, that was to cut 20 percent of present achievement standards. The characteristics of changes in achievement standards were to enhance the relation to practical life, to integrate the content elements separated, and to adopt the achievement standard to introduce new concept. Second, the number of inquiry activities presented in the 2015 revised science curriculum was also slightly decreased, and to be linked with the changes of achievement standards. In some cases, the range of inquiry activity was adjusted, or the unit to present it was changed. Teacher should know exactly about the elements to be changed in the 2015 revised national elementary school science curriculum, and it will be needed them to make an efforts in the cause of its smooth application.

본 연구는 학교도서관에서 정보활동을 통한 미래자서전 쓰기 프로그램을 전개한 후 고등학생의 자아정체감에 어떤 영향을 미치는지를 알아보는데 목적이 있다. 이 연구는 고등학교 2학년 198명을 대상으로 진행하였다. 정보활동을 통한 미래자서전 쓰기는 주 1회 50분씩 총 15차시에 걸쳐 학교도서관에서 이루어졌으며, 학생들은 자신과 자신의 삶에 대해 알아볼 수 있는 정보활동을 전개한 후, 이를 바탕으로 미래자서전을 쓰고 한 권의 책으로 만들어냈다. 사전-사후 대응표본 t-검증을 통해 미래자서전 쓰기 프로그램 적용 전후의 자아정체감 변화를 분석한 결과 유의미한 차이가 있는 것으로 나타났다.

This study was conducted to analyze the distribution and characteristics of fungal species in meju using the traditional method. Fungal distribution in meju was investigated using metagenomic and morphological analyses, based on which Aspergillus flavus/oryzae strains were identified as the dominant fungi in all meju samples, followed by Pichia, Rhizopus and Lichtheimia spp. As A. flavus/oryzae was dominant, we further evaluated the aflatoxin production ability and enzymatic activity of the isolates. Thin-layer chromatography and polymerase chain reaction revealed that the A. flavus/oryzae strains isolated from meju are non-aflatoxigenic fungi. Based on the analyses of amylase and protease activities, strains with high activities of amylase or protease were identified, which are proposed to be used as starters for meju fermentation.
