Research On Teaching Strategy Of Mathematical Proposition For Senior High School

With the development of modern didactics, teaching strategy is increasingly attracting people's attention. The mathematical propositions play an important role in mathematics teaching, therefore teaching strategy of the mathematical proposition (TSMP) will exert a vital influence on stepping up quality of mathematics teaching for senior high school.According to the using range of TSMP, it can be categorized into two types. One is macroscopical teaching strategy including the integration strategy and the reflection strategy. The other is microcosmic teaching strategy that consisted of teaching preparation, teaching operation and teaching evaluation. The teaching operation strategy is composed of the situation strategy in the stage of acquisition of mathematical proposition, the process strategy in the stage of proof of mathematical proposition, the production strategy in the stage of application of mathematical proposition. The seven teaching strategies form the system of TSMP for senior high school.Then, they are discussed in detail theoretically from seven aspects that mentioned just before on one hand. Concretely speaking, the integration strategy contains forming chunks and putting the "integrity-part-integrity" in teaching practice. The preparation strategy involves three micro-strategy, the first is the establishment of teaching target, the second is the measurement of the initial learning state of students, the third is the selection of the assimilative patterns of teaching-learning of mathematical proposition. Some methods of setting up mathematical proposition situations are introduced in the situation strategy. The process strategy emphasizes the process of exposing thinking, the process of discovering reasoning and proof, the process of abstracting and using mathematic thought and methods. The production strategy contains two methods. One is the change of exercises, the other is the algorithm of procedure. The evaluation strategy concludes three aspects as bellow: compiling the test questions, the main means of school achievement evaluation, and the disposal of the school achievement. The reflection strategy comprises both the teaching reflection of teacher and the learning reflection of student.On the other hand, the teaching strategies are amended and made perfect by means of soliciting the expertise in order to justify the reliability and the validity of them. As a result, the investigation indicates practically that the system of TSMP for senior high school that we have constructed theoretically gains a wide range of recognition from some teaching experts. In addition, the case study on experts" strategy-using indicates that it is effective.Some problem of using TSMP indicates the weak consciousness of teaching strategy in senior high school at present. There are five reasons for explaining that. The first is the deficiency of integration strategy. The second is that some teachers don't pay enough attention to the situation strategy. The third is that the extent of implementing the process strategy is not very large. The fourth is the spontaneous application of the production strategy. The fifth is the low level of the evaluation strategy and the reflection strategy. TSMP will be the effective countermeasure to resolve these problem.
