The purpose of this action research is to develop a concept-based teaching model and present unit design principles and application methods for ‘deep learning’ in elementary school classrooms through educational technology. To this end, we formed advisory groups and working groups for the development and application of concept-based teaching models and analyzed cases of field classes designed and implemented as concept-based curriculum. In addition, we established a framework for developing a concept-based teaching model and developed the teaching model by repeating the process of case analysis, model planning, model deliberation, and model modification. As a result of the study, the concept-based teaching model was elaborated into concept recognition, concept connection, concept implementation, and concept transfer, and was categorized into inquiry topic classes, competency building classes, and project classes applicable to elementary school classroom classes. In addition, by reviewing the design-implementation-creation process of concept-based classes, the core principles of unit design and teaching methods that affect elementary school classroom classes were presented as: integration and purpose, diversity and connectivity, clarity and effectiveness, and creativity and immersion. In particular, through focus group interviews with the advisory groups and working groups that participated in the study of the concept-based teaching model, implications for the application and implementation of classroom teaching were derived by dividing them into instructor-led ‘expansion of conceptual understanding’ and learner-led ‘implementation of in-depth learning’ aspects.
