Phenomenography is one of the methods of qualitative research and is located in the domain of interpretive paradigm. This methodology was created in the 1970s at the University of Gothenburg, Sweden. The basis of this approach is based on the fact that different people can have different experiences or concepts of one phenomenon. The use of phenomenography in empirical sciences, such as chemistry, can be seen as the discovery of different aspects of this science. Therefore, in present research, we tried to help the better education of this science by integrating the teaching of the electrochemical and oxidizing-reduction reactions and taking advantage of the learners' experiences. A content based on phenomenography was designed and taught. A questioner containing 33 question was prepared and after evaluation and confirmation was employed for assessing of the method effectiveness. The coefficient of difficulty, the coefficient of cleanliness and the internal co-ordination coefficient of the questioner were assessed by pre-test and post-test. The data were analyzed by SPSS software. The results indicated that the teaching of redox reactions by the phenomenography method is effective.
