One of the important competencies in knowledge and information society is the competency of Knowledge information processing. This is closely related to science education and described as one of the core competencies in the 2015 national curriculum revision. Even with a general agreement of the educational necessity of this competency, its practice in class depends mostly on teachers' will. Therefore, we surveyed science teachers' perceptions and classroom condition about the competency of Knowledge information processing, and we analyzed the questionnaires of 64 middle and high school teachers in Seoul and interviewed three teachers. As a result, all teachers shared the importance of Knowledge information processing competency and explained it in terms of social paradigm and goal of the subject. However, there were not many cases of actual practice in class. The teachers answered that time for Knowledge information processing competency is not enough in class and they also lack of PCK on this competency. About half of the teachers had experiences in teacher training about Knowledge information processing competency but most of their experiences are related to information utilization literacy. The importance of Knowledge information processing competency was very high in three factors (collection, analyzation, and utilization), among which information analysis was the highest. Middle school teachers showed higher scores in most questions even though the differences were not significant, and high school teachers showed higher scores in the importance of information sources at a significant level. In order to cultivate competencies, it is necessary to expand the meaning of science inquiry so as to cover this competency and to consider ways of linking with other subjects and develop methods of teaching and learning.

현대사회를 지식 정보사회라고 한다. 정보 매체인 컴퓨터의 등장은 모든 분야에 획기적인 변화를 가져왔고 그 변화는 계속되고 있다. 교육의 분야도 예외가 아니다. 업무처리와 학생지도에 컴퓨터가 도입되면서 능률적인 일처리와 다양한 방법의 학습지도가 가능하게 되었다. 초등 컴퓨터 교과가 재량활동의 교과로 선정되면서 컴퓨터 교과에 대한 교육과정 개발과 평가방법의 연구가 활발하게 전개되고 있다. 모든 교육활동에 있어 평가라는 부분을 그 교육활동의 성패를 좌우하는 중요한 요소이기에 아주 중요한 부분이다. 초등 컴퓨터 교과에 대한 전반적인 내용과 평가 방법을 살펴보고, 각 단계별 영역별 내용에 따른 평가 예시를 하였다.

NCS 기반 교육과정은 산업현장의 국가직무능력(National Competency Standards: NCS)을 고교 직업교육과정에 적용한 2015 개정 교육과정이다. 따라서 전문교과 교사는 학습자가 학습 종료시점에 NCS 수행준거를 만족하는 역량을 갖추도록 교육할 수 있는 교수역량을 필요로 한다. 이에 본 연구는, NCS 기반 교육과정 '전자' 교과의 실무과목, 학습모듈, NCS를 분석하여, 기초과목이나 실무과목으로 편성되지 않은 마이크로 프로세서 기본 역량에 대한 선수지식을 여러 영역에서 요구하고 있음을 밝혔다. 그러므로 NCS 기반 교육과정의 원활한 운영을 위해 '전자' 교과 교사는 마이크로프로세서관련 지식, 기술, 태도에 대한 교수역량을 강화할 필요가 있고, 학습모듈과 NCS는 수정 보완될 필요가 있음을 제안한다.

Geological information on the Korean Peninsula plays a significant role in science education because it provides a basic knowledge foundation for public use and creates an opportunity to learn about the nature of geology as a historical science. In particular, the Mesozoic Era, when the Korean Peninsula experienced a high degree of tectonic activity, is a pivotal period for understanding the geological history of the Korean Peninsula. This study aimed to analyze whether content regarding the geology of the Mesozoic Era are reliably and consistently presented in the 'Geology of the Korean Peninsula' section of Earth Science II textbooks based on the 2015 revised curriculum. Four textbooks for Earth Science II were analyzed, focusing on the sedimentary strata, tectonic movement, and granites of the Mesozoic Era. The analysis items were terms, periods, and rock distribution areas. The consistency within and among textbooks and of textbooks and scientific knowledge was analyzed for each analysis item. Various inconsistencies were found regarding the geological terms, periods, and rock distribution areas of the Mesozoic Era, and suggestions for its improvement were discussed based on these inconsistencies. It is essential to develop educational materials that are consistent with the latest scientific knowledge through collaboration between the scientific and educational communities.

The purpose of this study was to analyze teachers' pedagogical content knowledge on probability. Teachers' pedagogical content knowledge on probability was analyzed in detail into 2 categories: (a) subject matter knowledge, (b) knowledge of students' understanding and misunderstanding. The results showed, in terms of the subject matter knowledge, that the teachers have some probability misconception. And, it showed, in the point of the knowledge of students' understanding, they could not explain why students have difficulties to solve some tasks with regard to probability. This study raised several implications for teachers' professional development for effective mathematics instruction.

지식하부구조는 '능력'의 형태를 띠고 있다. 능력은 기본적으로 지식의 형태로 존재하게 된다. 그러나 이 지식은 기초연구 또는 교과서나 설계도와 같은 형식화된 지식만을 지칭하는 것이 아니라 공식언어로는 제대로 표현되지 않는 암묵적인 지식(tacit knowledge)까지 포괄하고 있다. 암묵적인 지식은 일반적으로 기업 특수적 성격을 지니고 있거나 산업 특수적인 성격을 지니고 있다. 암묵적인 지식은 공동의 경험을 지닌 사람들이나 조직들 사이에 공유되는 지식이기 때문이다. 이러한 측면에서 보았을 때, 능력으로서 존재하는 지식하부구조는 특정 산업이나 영역에서 국지성을 지니고 있다고 파악된다.

21세기는 지식과 정보량이 폭증하여 방대한 정보를 신속하고도 체계적으로 전달할 수 있는 정보통신 기술의 중요성이 그 어느 때보다 강조되는 지식정보화 시대이다. 지식정보화 사회는 무엇보다 컴퓨터와 정보통신기술(ICT: Information ＆ Communication Technology)이 주도하는 사회로서 정보와 지식의 생산과 소멸이 급속하게 이루어지기 때문에, 이러한 변화에 적극적으로 대처하기 위해서는 자신에게 유용한 정보를 찾아내고 분석하여 활용하는 능력이 필요하다.(중략)

This study analyzed the items for the Home Economics teacher selection test, which were carried out through the school year 2002 to 2010, based on Pedagogical Content Knowledge in Home Economics Education (H-PCK). Two frameworks were used: (1) H-PCK matrix transformed from the Content Knowledge in Home Economics Education (H-CK) and the Pedagogical Knowledge; (2) Five components of H-PCK. The results of this study were as follows: (1) The test items were classified into H-CK items and H-PCK items from the H-PCK matrix analysis. (2) While the number of items on knowledge of teaching strategies was the highest, no item on knowledge of understanding students was identified. Since the test can be considered as Measurement-Driven Instruction, it will have backward influences on the teacher education program in universities. Thus, if promising and capable new Home Economics teachers are to be recruited, the test items should include all the components of H-PCK.

The new knowledge in the textbooks for Physiology and Hygiene in Korea 1905-1910 was focused on the problems of hygiene. Lighting, ventilation, dryness were proposed as main conditions fer hygienic housing, for which management and planning methods were explained. This knowledge was taught as 'scientific' or 'modern' knowledge based on the physiological theory and air property, thereafter the conditions were placed as important conditions of modern housing.

The purpose of this paper was to investigate the pedagogical content knowledge of a middle school mathematics teacher manifested in his mathematics instruction by identifying the components of the pedagogical content knowledge of the teacher. For the purpose of the study, I conducted an interpretive case study by collecting qualitative data. The results showed that the pedagogical content knowledge of the teacher was characterized by: (a) knowledge of mathematics including connection among topics and various ways of solving problems; (b) knowledge of students' understanding involving students' misconceptions, common errors, difficulties, and confusions; and (c) knowledge of pedagogy consisting of his efforts to motivate his students by providing realistic applications of mathematical topics and his use of materials.
