This paper takes information technology classroom teaching in middle school as an example, analyzes how to treat individual differences objectively and perfect teaching behavior art, and puts forward corresponding strategies, including: Students interact, active classroom atmosphere The achievements of the research studies in PolyU have been encouraging. Our researchers have brought forth significant improvements in people's lives. One of the best examples is PolyU's successful development of space tool..

【Key words】 Individual differences Teaching behavior Perfection.

Information technology course as an era, cutting-edge, very obvious development of the discipline, has always been an important component of the overall quality of individual students in the new era. For middle school students, the same is no exception, to grasp a solid foundation of information technology is an important part of learning other knowledge and improving their overall competitiveness. However, for the course of learning information technology, different students lead to great differences in the learning of information technology because of differences in learning foundation, learning ability, hobbies and interests. Moreover, each person's growth environment is different, contact with things are also different experiences are different, so these differences are irreparable. In teaching practice, many of our teachers often do not take this objective difference seriously, but instead adopt more "one-size-fits-all" teaching methods to try to make students achieve the same progress through uniform teaching methods [1] . In fact, this kind of teaching method not only does not achieve the desired result, but also tends to be less effective. For this reason, this article takes the information technology classroom teaching of middle school as an example, explores the new thinking of differentiated teaching based on the objective reality of students, and provides reference for improving teaching behavior and constructing efficient classroom.

Scientific and rational stratification

Differentiated teaching, we must first be a reasonable classification. Specific to a high school information curriculum class, our classification can not be random, but to combine the students' learning ability, knowledge background, hobbies and other comprehensive development of a standard, and then divided into students A, B, C Three groups. If there are more classes in the school, the school can also mix and match several classes of students. In the information technology class, students in similar classes can go to a class. In this way, teacher preparation will be more targeted; for less-sized schools, you can study in the same class, but this puts more demands on teachers' preparation and teaching levels. In general, in this case, the teaching of teachers need to take into account many aspects. Through the hierarchical questioning, the method of hierarchical appraisal is reflected. There are also differences in the goals set for different students. Specifically, the principle of setting the level of delamination should follow the principle of "allowing all students to meet the basic goals of the syllabus and allowing students with spare capacity to study beyond the requirements of the curriculum" , So that the target level with all types of students to adapt to the existing level of development, so that students from different starting point have the power to reach the goal [3].

2. Continuous improvement of classroom teaching methods

Hierarchical teaching refers to the teaching mode adopted by teachers according to the students' psychological characteristics and different personalities in order to promote the full development of each student on the basis of the original. Different levels of students, different types of students have different needs. Therefore, teachers in the teaching process, for different students need to take different teaching methods, focusing on the combination of student psychology. For example, some poor students, many of whom are self-defeating, and very sensitive. At this time, teachers can not blindly use various measures in the classroom to seal off students' bad behavior. Instead, they should conscientiously guide each student according to the characteristics of each student, To make it clear right and wrong, so that students feel that teachers are really concerned about me, students will slowly form a learning self-confidence. This requires that teachers should learn to treat students with appreciation of the eyes, especially poor students, it is necessary to seize each of their bright spots, to enlarge and encouragement, so that students can slowly feel the sense of learning and gradually Combined with their own situation to form a learning program.

3. Strengthen teacher-student interaction, active classroom atmosphere

In an efficient classroom, students tend to "enter the role of" emotions, which is what we call concentration and motivation to learn more strongly. The relationship between the cultivation of learning motivation and teacher-student relationship is inseparable [4]. Information technology is no exception to this discipline, in order to achieve efficient classroom, inseparable from the efficient interaction between teachers and students in the classroom atmosphere. Especially in the process of differentiated teaching, teachers also need to master the classroom art, the students at different levels, their motivation can be mobilized. For example, group cooperation study is conducted, and students are divided into study groups according to the principle of heterogeneity in the same group. Let each group have poor students, secondary students, and excellent students, so that different levels of learning together they can learn from each other, complement each other. Coupled with the teacher's scientific and rational arrangements for learning content and scientific guidance, students can effectively stimulate their own potential. This requires teachers to use more rich language, and changing teaching methods to mobilize the enthusiasm of students to learn, active classroom atmosphere. Including scenarios teaching, case teaching, teacher-student role conversion, etc., can be integrated into the information technology classroom under the concept of differential teaching.

According to modern psychology, "human behavior is based on specific desires, in order to achieve specific goals and to choose various means to achieve the goal." Our classroom teaching behavior is the same, as to what kind of teaching behavior must be art, what kind of teaching behavior can achieve the goal of efficient classroom, this is not conclusive. Only when teachers combine the actual needs of the classroom with continuous exploration and perfection in teaching can they eventually form a teaching behavior that suits the actual situation in different places and this behavior can be called "art" by us Want a variable voltage battery?
