Practical Research On Problem Strings In Mathematics Teaching In Primary Schools

In our country "compulsory education mathematics curriculum standard(2011 edition)" asks the student: "The preliminary learns to discover the problem and the question from the mathematics angle,uses the mathematics knowledge to solve the simple practical problem comprehensively,enhances the application consciousness,enhances the practice ability;Learning to work with others;To form an initial sense of evaluation and reflection.Problem teaching is a series of questions that teachers use to guide their students to acquire knowledge.In the process of learning,students not only need to combine the existing knowledge background and life experience,but also need divergent thinking,positive thinking to solve the problem.Therefore,the use of question string teaching can strengthen the relationship between mathematics knowledge and practical life,enhance students 'interest in learning,conducive to the development of independent learning habits.Because the fourth edition of elementary school mathematics textbooks in Peking University in 2014,"situation + problem string" teaching model,so the research on problem string teaching has not formally formed the system,there is no authoritative standard to refer to.The author hopes that through his own efforts,can enrich the problem teaching related research,for educators and scholars to provide certain reference.The following are the main aspects of this study:First of all,the author has read a lot of literature about the question string,and made a serious analysis and reflection on the previous research results,combing out the origin,steps,principles,notes and functions of the question string.On the basis of previous studies,the author defines the core concepts of "problem string" and "elementary mathematics string".Secondly,after analyzing the design of the question string in the elementary school mathematics textbook,the author made a questionnaire survey to the teachers to understand the value,use and design ability of the question string.At the same time,a questionnaire survey was conducted among 300 primary school students to find out their attitude,habit and ability to study mathematics,so as to lay the foundation for the design of the question string.Then,in order to test the effectiveness of the teaching strategy of the question series,the author made an experimental study on the students in the fourth to sixth grade,using the comparison between the experiment class and the contrast class before and after the experiment to explain.Finally,through the experiment,we can see that the interesting situation is more interesting for students;The student's inquires the atmosphere is thick,helps the student to cultivate the good inquires the habit;Problem strings can be applied to students at different levels of learning,promoting the development of each student.
