The purpose of the study is to design a lesson plan model for character education in primary education, and to elicit the related stakeholders' opinions and suggestions on the proposed lesson plan model. As a qualitative design research, the data in this study were collected through written document analysis and interview. Criterion sampling method was used to determine the participants of the study. The participants were five primary education teachers, two experts from the field of psychological counseling and guidance, and two academicians from the department of elementary education. The data were analyzed using content analysis. The study has two phases: (1) developing lesson plan model on the basis of the affective domain grounded by Krathwohl, Bloom and Masia and eleven principles of effective character education proposed by the Character Education Partnership, and (2) piloting the model. Up till now, the 1st stage has been completed. The results indicated that the participants mostly gave positive feedbacks in terms of fundamentals, parts and steps of the model. Moreover, the assessment and evaluation part of the model might be a weakness. Finally, the results indicated that the suggested model will be a pathway in the application of character education in primary schools. The lesson plan model will be piloted as a follow-up research.
