【 摘 要 】

In this study, the educational effect was investigated by providing a teaching program so that pre-service chemistry teachers could apply model ignorance education to teacher training practice. The teaching program was constructed inconsideration of the sensemaking concept proposed in the study of Odden & Russ and the process of teacher sensemaking proposed by Asli et al. The subjects of this study were 23 pre-service teachers in the 4th year of chemistry education departmentat a teacher training university in the central region of Korea. In order to form a sensemaking for the model's ignorance education, the teaching program consisted of four stages; the initial idea generation stage, cognition of model's ignorance stage in ainconsistent situation, the lesson strategy construction stage for model ignorance education, and lesson plan & practice stageduring teacher training practice. In the first stage of this program, pre-service teachers' initial ideas about the Arrhenius modeland Bronsted-Lowry model of acid-base reaction, and the electron transfer model of the oxidation-reduction reaction wereinvestigated. In the second stage, inconsistant situation that cannot be explained by the knowledge of model was presented torecognize the ignorance of the model. The third stage was to develop the teaching ability of model's ignorance through textbook analysis and lesson strategy composition activities. As a final stage, during the teacher training practice, the pre-serviceteachers were asked to plan and practice the implementation of the model's ignorance education. Through the teaching program to form a sensemaking for ignorance education of the models, pre-service teachers had come to recognize the ignoranceof the model, acquired ability to organize and execute lesson strategies reflecting model ignorance, and acquired recognitionof the educational value and necessity of teaching the ignorance of models.
