Research On PCK Learning Process Of Chemistry Normal Students

PCK is the core knowledge that teachers must have,As an important reserve force of the teacher team,the improvement of the PCK level of this group will have a profound impact on the quality of the teaching staff.The PCK of chemical normal students is a dynamic development process,which is gradually constructed by means of the study and teaching practice of the various courses of college teacher training.Therefore,the level of PCK for chemical normal students in different learning stages is gradually improved,thus have the characteristics of the learning progressions.To this end,the study of the learning progressions of chemical normal student's PCK can provide a tool for exploring the development status of PCK.It will make chemical normal students and training units to keep abreast of the problems in development and further optimize professional training programs and curriculum teaching.Therefore,the research of this subject has important practical significance.The data shows that there are few research literatures on the PCK based on the learning progressions.For this reason,the author first constructed the PCK system of chemical normal student,and then constructed the PCK learning progressions of chemical normal student according to the teacher educational course standards,the teacher qualification test requirements and the SOLO theory.And through the case study,test survey and other methods,start the actual exploration of the PCK learning progressions about 310 chemical normal student in the college where the author was located,and analyze the factors affecting the PCK learning progressions of chemical normal student.On this basis,the paper summarizes the training suggestions of the PCK based on the learning progressions theory.
