온-오프라인 혼합 학습환경에서 과학교사의 교수 지향과 PCK 특징

This study explore characteristics of teaching orientation and pck of science teachers in online-offline mixed learning environment. Data consisted of open-ended survey, semi-structured interview, class observation, field notes from 12 science teachers. We categorized teaching orientation considering both science education goals and science teaching·learning orientation. There were 8 different teaching orientations such as ‘understanding science concepts-lecture centered’ ‘constructing science concepts-inquiry based’ ‘applying science concepts and inquiry-inquiry based’ ‘applying science concepts and inquiry-lectured centered’ ‘analyzing and judging science information-inquiry based’ ‘developing scientific attitude-inquiry based’ ‘developing scientific attitude-lecture centered’ and ‘developing perception of interrelationships among science, technology, and society-inquiry based’. Teachers with inquiry based teaching·learning orientation seemed to have knowledge of science curriculum specific to online learning environment for student inquiry. While teachers with ‘understanding science concepts-lecture centered’ teaching orientation appeared to have questioning strategy of checking student understanding and strategy of repeating a lecture, teachers with ‘constructing science concepts-inquiry based’ teaching orientation appeared to have knowledge of instructional strategies to perform online group activities targeting student construction of knowledge and to replace face-to-face group activities with virtual experiments and individual experiments. While teachers with ‘understanding science concepts-lecture centered’ teaching orientation did not show knowledge of student science learning, teachers with ‘constructing science concepts-inquiry based’ teaching orientation appeared to have knowledge of student difficulties in inquiry based learning.
