| Middle school mathematics is a strict logic system which mainly consists of concepts,theorems as well as formulas,etc.While,the theorems and formulas are important components of the proposition.Thus,proposition plays a significant role in middle school mathematics which should not be overlooked.Therefore,in the field of mathematics education research,studies on proposition teaching have always been one of the hot topics.But in fact,many teachers still fail to recognize the importance of proposition teaching.These teachers ignore the sources of proposition and lack the proving process of it.They only pay attention to its application.Teaching in this way is like building without foundations.Therefore,proposition teaching of middle school mathematics should be one that has a clear source,a complete process and a flexible application.This paper,based on Professor Ying Zhou’s view,"six questions",establishes "six questions and interaction" teaching mode in middle school mathematic proposition teaching.The teaching strategy of this model centers on question-driven,emphasizing the continuity of teaching,students’ participation as well as diversity of variant."Six questions" are as follows:"where does it come from","what is it","what are the connections between it and knowledge learned before","how to prove and apply it","what will happen if the conditions are changed"and "what can be learned from it"."Interaction" means the teaching activities will be carried out in the form of teacher-students and students-students interaction.On this mode,proposition teaching,based on the idea of "six questions and interaction","six questions" as teaching thought and "interaction" as the target effects,will help students develop step by step.In this paper,"six questions and interaction" teaching mode is studied in speculative theoretical and empirical research method.This paper is divided into the following six sections.First,this paper talks about the importance of proposition teaching in middle school mathematics education.And based on the "six questions and interaction" teaching mode,the study contents,purposes and research methods are decided.At the second part,key concepts involved in the "six questions and interaction" teaching mode in middle school mathematics proposition teaching are defined.Then this paper collects and sorts out the existing research achievements of at home and aboard.At the fourth part,taking psychological and educational theories as reference,this paper brings forward the framework,process implementation and strategies of "six questions and interaction" teaching mode in middle school mathematics proposition teaching.Next part is about the teaching experiments and surveys on middle school students.These experiments and surveys have been carried out under the proposition teaching mode and strategies proposed and from which a number of teaching cases and data have been collected.By means of statistical tools,the effectiveness of this mode are analyzed and checked.At the last part,making summary of reflection,this paper points out its deficiencies and development trend on this field.Using qualitative and quantitative research methods and after analyzing those experiment data,this paper comes to an conclusion that "six questions and interaction" teaching mode in middle school mathematics proposition teaching has great effects on improving students’ marks and question-asking ability as well as learning transfer ability.The innovation of this study lies mainly in that it builds up "six questions and interaction"teaching mode in middle school mathematics proposition teaching and comes up with corresponding teaching strategies.This study tests the teaching mode by teaching experiments and provides a new model reference for middle school mathematics proposition teaching. |
