The purpose of this study was to explore competencies for teachers to implement flipped
learning effectively. Teachers at the flipped learning should be able to develop various forms
of pre-class materials, design an on/off-line learning environment, and utilize appropriate
instructional strategies when considering diverse students’ characteristics and task types.
Thus, competencies need to be explored for teachers to effectively implement flipped
learning class. For this purpose, literature reviews on competency requirement for teachers
was performed, followed by interviews with experts and teachers. Through these processes,
a draft of the competency criteria was derived. Then, delphi survey of elementary and
middle school teachers was conducted and the derived criteria was confirmed. As a result,
eight competency factors and twenty-four competency indicators were finally derived
according to three instructional stages (before-class, in-class, and after-class) of flipped
learning: Learning design competency and learner management competency at the
before-class stage, learner facilitation competency and moderating learner performance
competency at the in-class stage, and supporting in-depth learning competency and
evaluation competency at the after-class stage. The findings from the results will be used for
developing competency-based teacher training program. In addition, the identified
competencies in this study will be used for teachers to evaluate their own readiness for
flipped learning.
