The purpose of this study is to investigate the effects of restricting children’s free play on children’s levels of pretend play. The level of play restriction was examined using the following: How many children can play in the same area of interest, freedom of using toys, the space available for play, and time limitation. The participants for this study were selected through two screening steps. First, a questionnaire concerning the extent of free-play restriction was sent out to 90 teachers... -

이화여자대학교 교과교육연구소 교과교육학연구 2017, 제 21권 4호 13 450-458 (9 pages)
We investigated Korean preservice elementary teachers’ mental images of science inquiry and inquiry teaching with respect to 8 specific Science and Engineering Practices (SEP). The preservice teachers had learned about science inquiry, but were not taught these SEP in their Korean curriculum. We asked them to draw and explain an imagined situation where they would be teaching science inquiry in an elementary science classroom. Some were also asked to describe an imagined situation of scientists... -
건전한 온라인 이용 습관 형성을 위한 초등교육의 방향
한국인간발달학회 인간발달연구 2003, 제 10권 제 1호 4 57-72 (16 pages)
컴퓨터 네크워크가 우리 생활의 모든 부분에 영향을 미치게 되면서 많은 전문가들은 가상경험의 부작용에 대하여 우려의 목소리를 높이고 있다. 특히 아직 자아가 형성되지 않은 온라인 아동 이용자들이 직접 데이트 사이트에 접속하여 성매매에 가담하고 있는 가 하면, 온라인 게임에 중독되어 이를 중단하면 마치 오프라인상의 친구를 잃은 것처럼 금단현상에 시달리고 있다. 뿐만 아니라 화상 채팅을 가능하게 하는 기술발달은 또 다른 중독양상을 유도하고 있으며, 가족간의 친밀감을 손상시키는 등 가상경험은 아동의 인지, 정서 및... -

설정하였다. 디폴트베이즈요인(default Bayes factor)은 Spiegelhalter와 Smith (1982)가 계발한 가상적트레이닝표본법(imaginary training sample method)을 사용하여서 도출하였다. 또한 제안된 베이즈판별변수선택 기준이 지닌 분포의 성질을 이용하여, 추가 판별변수(또는 변수군)가 MDA에 기여하는 부가적인 판별력에 대한 검정법 및 추가판별변수(또는 변수군)의 선택 기준에 대해서도 논하였다. 본 연구에서 새로이 얻은 변수선택기준은 최적부분집합선택법(optimal subset selection method)뿐 아니라 각 단계적방법(stepwise... -

Objective: The aim of this study was to investigate the inter-rater and intra-rater reliability of rehabilitative ultrasound imaging (RUSI) for measurement of muscle thickness with changes in angles of the gluteus maximus (GM) at rest and during contraction. Design: Cross-sectional study. Methods: Twenty-two healthy men volunteered for this study. GM muscle images were obtained in the resting position and during prone hip extension with knee flexion at hip abduction angles of 0° and 30°,...
