"The Problem String" In Application Of Junior Middle School Mathematics Class Teaching

For answers, the origin of education, can be traced back to ancient Greece, when the famous philosopher Socrates was catechetical teaching, this can be thought of as" string" initial form. The so-called Socratic teaching, is a teacher according to the teaching contents according to the actual situation of the students, ask questions, and students of the teacher’s question. This question can be to a large extent inspire students’ thinking, through their own analysis and discuss, find out the answers to the questions in the process, is the process of enhancing the ability of students to self. Through this process, students can also divergent thinking, make the students to explore knowledge, the ability of unknown problems thinking ability has been greatly improved. At present, the junior middle school new course advocates the inquiry learning in junior high school mathematics textbook, many chapters have adopted the" string" in the form of leading students to analyze, solve, therefore, in-depth study of the" string" in junior middle school mathematics classroom teaching has great practical significance.The so-called" string" is to show in certain scope of learning or teaching goals within the field, teachers according to the curriculum setting of the teaching goal and students’ learning situation, the knowledge center, corresponding to the specific teaching environment and theme, according to a certain logic structure and the students’ psychological characteristics in learning, and designed a series of problems, thus, to meet the various levels of the students’knowledge of learning needs. Therefore, teachers in" string" design, should from the outside to the inside, from the shallower to the deeper, from phenomenon to essence of the progressive levels of design, reflect the ladder of education mode, which is shown in front of everyone." String " put forward, to a large extent improve the contemporary education problems in practice, teachers can design the corresponding teaching content according to the" string", carry out the problem teaching, lets the student in a series of problems to find the problem, and solve problems. Students with problems in the learning process, to improve their learning methods, improve their thinking quality.This article mainly through literature method, comparative analysis, empirical research on the "string" design and application to be elaborated in the round. The first part of this article has analyzed from the junior middle school mathematics classroom teaching present situation, proposes the" string" teaching thought. The second part of the" string" teaching thought of. Discusses the" string " meaning and its teaching characteristics, as well as the" string" thought in mathematics teaching and its significance in the junior middle school mathematics classroom teaching. The third part of this paper, studied the" string" in the junior middle school mathematics teaching practice in specific application. Include" string" design principles, methods, requirements, in the actual teaching case analysis as well as the" string" in the course of using the existing problems discussed. The last part is a conclusion.
