Research On Development And Application Of Primary School Mathematics Problem-solving Mini-lesson

The education department published “National medium and long term plan for reform and development of education(2011-2020)” that advanced a proposition called the great influence of information technology on educational development.So that we pay more and more attention to educational informationization.The teaching reform of mathematics at the elementary school should adapt to the reform.From "teaching and learning environment" and "teaching and learning mode" of information,using the existing information technology and educational informationization construction foundation to optimize the education environment,solve the problems existing in the elementary school mathematics teaching and learning,and promote the development of elementary education.In 2001,our country promulgated the "full-time compulsory education mathematics curriculum standard(experiment draft),which firstly proposed that "problem solving" should be listed as one of the four goals of mathematics teaching.During 10 years when the standard is put forward,research literatures on "the elementary school mathematics problem solving" were published all the time,the elementary school mathematics problem solving is a hot topic of current research.The development of primary problem solving is not only the requirements of national curriculum reform,but also the present elementary school mathematics problem solving teaching and research progress of the key.According to the investigation,most of the researches on solving problems of primary school mathematics focus on the teaching situation,teaching method diversification and teaching strategy.There are only a handful of studies related to elementary school math problems.The teaching development of mathematical problem solving and informatization is stagnant.Moreover,the teaching demand of mathematics problem solving in reality has not been satisfied and improved.Therefore,this study mainly focuses on the development and application of elementary school mathematics.In order to provide theoretical basis for the thesis,The author arranges the research purpose and the significance of the research.In the early stage of the development of Mini-lesson,there are doubts in the study of mathematical problem-solving in elementary schools to verify the practical needs of the teaching of mathematics in primary schools.Under the guidance of ADDIE teaching design and development model and other relevant theories,the teaching contents and learners of the Mini-lesson of the elementary school mathematics "problem solving" are analyzed.Then the relevant Mini-lesson are designed and developed that are related to the first grade mathematics "graphics and text problem solving".They are applied to 6 classes in YiYuan primary school(hereinafter referred to as Y elementary school)in HuangPu District,GuangZhou.The author carries out the comparison experiment and obtains the experimental data which is used to analyze and conclude the effect of the application of Mini-lesson.Finally,this study concludes the application of Mini-lesson in solving the problem teaching and proposes the deficiency and prospect of the research.
