Based On The Problem Situation Of Mathematical Proposition Teaching Research

Middle School Mathematics is a rigorous logical system of concepts, axioms, theorems,formulas, etc. Proposition is the connection between concepts. Strengthen the teaching ofsecondary school mathematics proposition is always very important task in the Middle SchoolMathematics Teaching. In the secondary school, the basic requirements of mathematicsproposition teaching is to enable students to deep understanding the mathematical propositionsmeanings, clear its derivation process and the scope of application, and have the ability to makeflexible use of mathematical propositions to solve the problem. So，mathematical propositionteaching is of great significance and role of forming a good mathematical cognitive structure,developing analysis and problem solving skills and effective realization of mathematical problemsolving for students.The problem-situation teaching is based on Constructivism teaching and situation learning.The teaching method is made through setting up a suitable true question situation or somethingcontain mathematical problem according to the teaching task and students’ cognitioncharacteristic, which make students produce strong cognitive conflict through the association,imagination and reflection, and experience the process and significance of raising and solvingproblem simultaneously stimulates students further study and exploration. Using theproblem-situation teaching exposes students to the rich useful information, which are enablestudents to experience the emergence and development of mathematical propositions. Not onlyenables students to truly understanding the nature of mathematical propositions, but also skilledproposition to prove and use of migration and help the students of non-intellectual factors, whichembodies the thought of quality-oriented education. Therefore, mathematical propositionteaching using situational teaching is effective method to improve the efficiency andeffectiveness of the teaching and to enhance students’ mathematical literacy.Here mathematical proposition teaching using the problem-situation teaching has threesections, the teaching of posing mathematical proposition in physical situation，which canstimulate students’ interest and motivation and help study the last two parts；the teaching ofcertification of mathematical proposition in reciprocal situation can help students to experiencethe proposition to be proved and the problem-solving process; the teaching of application ofmathematical proposition in shift situation can make the teaching of mathematical proposition more effective.Through the classroom teaching experiments’ study in the high school to discuss how to putthe problem situation teaching into mathematical proposition teaching and how about the effect.With the purpose of using the class teaching to test the teaching theory, and hope this teachingtheory can receive evolvement and perfect.
