Teachers should set appropriate learning goals when preparing lessons, and confirm and coordinate the best way to achieve these goals. The traditional goal determination of preparing lessons is a kind of knowledge presupposition. The new curriculum standard requires students to realize the three-dimensional goals of knowledge and skills, process and method, emotion, attitude and values. The target design should be "third class". Traditional knowledge points and ability points are still what teachers need to pay attention to when preparing lessons, and the other two goals need to be considered. One is the consideration of technology and method, and the design must pay attention to it. Second, it can be understood as a requirement for intangible methods, emotions, attitudes and values, which is mainly manifested in cultivating students' learning psychology and learning quality of loving science, being diligent in thinking, being good at exploring, being good at cooperation and pursuing truth. There are two things to consider in preparing lessons: first, the knowledge and ability of this lesson, the mastery and application of theorems, and the understanding of the plane geometry knowledge learned in the whole junior high school. Second, we should give full consideration to the guidance of learning methods when preparing lessons. It is very important for students to learn some inquiry methods and skills in each class, and what kind of guidance the teacher will give. If we make some efforts in this respect, let students learn to learn, learn to learn actively, and learn to learn independently, the efficiency of learning will be reflected.
Second, we should consider the bilateral interaction between teachers and students when preparing lessons.
The new curriculum standard emphasizes that "teaching" serves "learning", and teachers realize teaching tasks by cooperating with students and relying on their own activities, practices, cooperation and exchanges; The new curriculum standard requires teachers to design teaching ideas with students' psychological development as the main line, predict students' possible thinking activities and design corresponding countermeasures. This requires us to let students participate in pre-class preparation, collect and make relevant materials (such as objects, pictures, data, etc.). Do it yourself, such as making an isosceles triangle parallelogram, and then try to study its properties. This process can not only promote students' autonomous learning, but also lay a good foundation for classroom teaching. It can also enable teachers to predict students' needs, grasp students' current level and emotional state, and grasp students' "current development level", so that teachers can consider lesson plans more from the perspective of students' learning when preparing lessons, suit the remedy to the case, and be targeted.
Three, prepare lessons should consider the individual differences of students, teaching students in accordance with their aptitude.
The new curriculum advocates the construction of teaching foundation, completes the premise of teaching, and understands the difference of teaching objects-student difference. When preparing lessons, we should carefully analyze the differences of students' knowledge structure and find the breakthrough point of new knowledge learning. Carefully analyze the differences of students' learning styles, design classroom teaching according to students' interests, hobbies and emotions, and grasp the encouragement points of learning; Carefully analyze the differences of students' learning needs, determine different levels of teaching according to the objects, and build a good learning bridge so that students with poor foundation can "eat" and those with spare capacity can "jump".
Only in this way, under the premise of mastering students' personality differences and individual needs, adopting different teaching methods can create conditions for each student's development, make students devote themselves to classroom learning activities, and make everyone get physical and mental pleasure and great development on the original basis. Therefore, it is very important for teachers to choose examples and students' training questions carefully. The selection of cases should be typical, representative and ideological. Special attention should be paid to the diversity of an example. Keeping close to the key points is conducive to the consolidation of basic knowledge and the mastery of laws. We should pay attention to the diversity of questions, variant training and exploratory training, and cultivate the ability to develop intelligence. For extracurricular homework, you can arrange appropriate questions and choose to do them to reflect the principle of teaching students in accordance with their aptitude.
Fourth, prepare lessons after class according to the teaching situation to improve the ability of teaching reflection.
It is important to prepare lessons before class and write lesson plans, but preparing lessons after class is more beneficial to teachers. The value of teaching plan lies not only in the preparation of classroom teaching, but also in recording teachers' teaching ideas and methods, and it is also an important material for teachers to know themselves and sum up teaching experience. In teaching practice, once the classroom is released and really alive, there will be many unexpected variables and students' questions.
Teachers record these emergencies after class, and make a rational analysis of their own teaching ideas and behaviors, students' performance and teaching success or failure. Through reflection, experience and feeling, help yourself to sum up and accumulate experience, and form a set of knowledge system and skills that can adapt to teaching changes and control classroom teaching well.
Under the new curriculum conditions, with the change of teachers' roles and students' learning methods, lesson preparation is no longer a simple interpretation of textbooks, a simple arrangement of teaching process and a simple display of teaching methods, but its nature, functions and methods have changed greatly. It requires teachers to strive to implement students' subjective learning status, autonomous learning and cooperative learning under the new curriculum concept, and fully mobilize the enthusiasm of each student.
