On the Function and Connotation of Context in Chemical Instruction

The function of context in subject instruction includes reviving inert knowledge,developing the understanding of the subject and improving the knowledge transfer from the school to the life world and the science world.Based on the analysis of diverse interpretation of context,a multidimensional understanding model of context which consists of subject knowledge,life settings,communication environment and learning activities is suggested.To implement the function of context in instruction,both the structural subject knowledge and diverse life settings should be integrated in the context while the diverse ways of practice and social cultural factors should be focused in devising learning activities.
