Mathematical Proposition Teaching On The Base Of Situated Cognition

Mathematical proposition belong mathematical basic knowledge, which is one of the chief content of mathematics learning. For a long time, the teaching of mathematical proposition is just telling. Students acquire algorithm, rules and definition out of situation through schooling teaching, but they don't know how to use the knowledge. Sit cog-based mathematical proposition teaching make it probable that students study more effective and avert their knowledge to reality situation.Theory of situated cognition insist set up students-centered learning environment. To analysis mathematical proposition learning and teaching on the base of situated cognition. The teaching of posing mathematical proposition in physical situation, the teaching of certificatio of mathematical proposition in reciprocal situation and the teaching of application of mathematical proposition in shift situation, can make the teaching of mathematical proposition more effective. The instructional design take the grounded theory on the base of learning and teaching of mathematical proposition analysis, which embodies the compact association between theory and practice. The instructional design is nolonger applied only after simply designed. It is a process of developing in a concrete learning-teaching context.The paper select a subject of middle school to survey, so as to discuss how to put the situated cognition theory into the mathematical proposition teaching in the practical teaching. And to compare the different teaching effect of the same proposition. The purpose is to apply situated cognition theory into mathematical classroom.
