A Case Study Of The Diversity Of Primary School Algorithms In The Perspective Of HPM

The history of mathematics into mathematics teaching(short for HPM)from the introduction to the promotion,and to the establishment of the HPM team,which has a history of 100 years.HPM teaching is helpful for students to understand mathematics better and enhance the interest of mathematics learning.At the same time,HPM teaching can promote students to establish a positive attitude of learning mathematics,improve learning motivation and the concept of discipline.With the deepening of the new curriculum reform,the history of mathematics as a carrier to improve students' mathematical literacy has also been paid more attention to by our country's mathematics educators.The new curriculum reform requires more emphasis on creativity and individuality for students' mathematical calculation and encourages the students to make the algorithm more diversified.The history of mathematics into mathematics teaching provides a new way of thinking for this problem.In this context,the study mainly uses the case study method and explores how to promote the teaching of algorithm diversification based on the perspective of HPM.The study provides case accumulation for the integration of mathematics history into primary mathematics calculation teaching.First of all,this study investigates the attitudes of mathematics teachers and elementary school students towards the mathematics history into mathematics teaching and the problems existing in the teaching of algorithm diversification by questionnaire.The survey finds that teachers have generally realized the value of mathematics history and the important value for the development of students,but there is not much application in practical teaching,mainly due to the lack of mathematical history,time and energy constraints,the neglect of mathematics history under the examination system.The students' survey shows that the students' knowledge of mathematics history is weak,but they are very interested in the history of mathematics and have a strong motivation to learn it.There is some confusion for teachers about how to guide students to diversify the algorithm in the traditional teaching methods.There is not enough attention and full use of the historical materials of mathematics in teaching materials either.On this basis,the study takes two digits number by two digits number as an example to carry on the teaching design and carry out the implementation and reflection.The results show that the integration of mathematics history into mathematics teaching can not only improve students'interest in learning,but also help to promote students' understanding of knowledge and help improve students' innovative consciousness.On the basis of practice and reflection,this study puts forward some suggestions on how to integrate the history of mathematics into the teaching of mathematics in primary schools.Firstly,excavate mathematical historical data and show the classic algorithm.Secondly,diversify in the history of mathematics.Thirdly,guide to compare advantages and disadvantages.Finally,learn a variety of algorithms independently and encourage algorithm innovation.
