Abstract This paper studied the connotation construction of Pedagogical Content Knowledge(PCK) and the development of teachers' PCK deepened into the level of specific teaching content. On the platform of the project of "high-end lesson planning" for the Institute of Chemical Education, Beijing Normal University, and taking "primary battery" of Chemistry 2 and the Principal of Chemical Reaction as the carrier, this paper put forward the analytical framework, developed the questionnaire based on this, and investigated in senior high school in Beijing before, during and after the training of "high-end lesson planning". The results showed that:In the course of "high-end lesson planning", the first dimension and the second dimension of PCK had been developed, among which the students' learning knowledge and teaching strategy knowledge were most obvious in these 2 dimensions, the improvement of the second dimensions were more significant, such as the electrochemical thinking model, the characteristics of students' cognitive development, the functional value of knowledge and the explicit expression of ideas. The teachers thought that the links of research and trial preparation in the training, analysis to explain, question and discussion of the guidance, questioning and discussion were the main reason for improvement of their PCK.
