Prepare well before class, carefully organize classroom teaching first, and prepare lessons is the premise. Preparing lessons is not simply writing lesson plans, but preparing teaching materials and students. And before teaching, we should make clear the teaching objectives, so as to improve the effectiveness of teaching content. The new curriculum standard requires the organic combination of knowledge and skills, process and method, emotion, attitude and values.
Second, in the process of teaching, only by understanding the students' reality can we be targeted. If you want to understand students, you must first understand students' ideological understanding, and you can estimate what ideas students need to guide in their study and how to guide them. The second is to understand students' learning situation, including students' learning attitude, learning foundation, learning habits and methods, acceptance ability, knowledge barriers and so on.
Thirdly, teachers, teaching materials, media and students should have a detailed design of all aspects of teaching and learning in classroom teaching before each class, including the explanation of reflecting on the remaining problems. Implementing the three-dimensional goal of the new curriculum reform efficiently, effectively and effectively has a preset guarantee.
Improving students' attention in class First of all, a good start is an important prerequisite to ensure a good class, and lively and interesting classroom introduction can make a class get twice the result with half the effort.
Secondly, a good math teacher should not only speak well in class, but also be good at adjusting the classroom atmosphere. In the teaching process, when students are sleepy and distracted, adding a humorous language naturally and skillfully can alleviate students' fatigue and concentrate in a cheerful atmosphere. Naturally, this active classroom atmosphere is also beneficial for students to accept and digest the lecture content.
Thirdly, experiencing the joy of success can also enhance the confidence of concentration. In the teaching process, students are constantly given opportunities to succeed, so that every student can get a successful experience and enhance their confidence in paying attention to the classroom.
The example exercises are modeled as "everyone learns valuable mathematics and everyone can get the necessary mathematics", which is the concept of mathematics education. Therefore, it is necessary to provide students with realistic, meaningful and challenging mathematics learning content, which is presented in the basic mode of "problem situation-modeling-explanation-application development". The reason why this model is adopted is to let students experience the process of abstracting mathematical models from the actual background, exploring quantitative relations and changing laws, guiding students to use their knowledge and skills to solve practical problems, enabling students to understand mathematics, develop problem-solving strategies, and experience the connection between mathematics and real life, thus cultivating students' practical ability and innovative spirit.
"The purpose of mathematics education is to make students learn to use mathematics for our own use." "The most important gain of mathematics learning is to learn to build mathematical models to solve practical problems." In order to urge mathematics teachers to realize the change of mathematics education concept as soon as possible. Therefore, the design of examples in junior high school mathematics review teaching should especially strengthen the teaching of mathematical model methods to make up for the shortage of usual teaching. The teaching of mathematical modeling method is to construct a mathematical model according to practical problems, that is, to investigate the relationship between main factors and related quantities according to the specific relationship of practical problems (limited to the knowledge level and cognitive ability of junior middle school students, the "practical problems" here are not real practical problems, but practical problems that have been "preliminarily mathematized") and specific requirements, and to use relevant mathematical knowledge and mathematical language to describe this relationship on the basis of abstract generalization.
Scientific training methods Only by adopting scientific methods and organizing training purposefully and planned can review get twice the result with half the effort. It is necessary to guide students to use textbooks and test scores, and correctly handle the relationship between memory, practice and test. At the same time, we should also infiltrate the local flavor and be close to life during training, guide students to care about local economic life and local economic development, and let students realize the practical value of mathematical knowledge in real life.
