I think homework before class should play a role in attracting jade, guiding students to enter the next class, so that students can predict and grasp the main context of the next class when completing homework before class. Teachers should really serve students' learning when designing homework before class 2. Some teachers design too much homework before class, which will make students confused and at a loss. On the contrary, it will be counterproductive and lose interest in learning. I don't think the content of the preview should be too much or too specific. We should leave room for students to think and ask them big and thoughtful questions, such as "What did you understand after reading the text?" "How do you feel after reading the text?" "What do you think of the hero in the article? Where can I see it? " "What do you think of this story?" In this way, when answering questions, students can have their own ideas and produce more on the basis of being familiar with the text. In the activities of the project group, Mr. Xue also mentioned that the homework on the study guide should be integrated, which is more targeted and oriented. Of course, in addition to designing questions for students, we can also arrange a series of creative tasks that students are interested in, such as drawing and performing, so that students can do their homework with a good mood, their thinking will be more active and their reaction to the industry will be more sensitive. In the long run, students will be full of interest and expectation in learning, and naturally they will get twice the result with half the effort in class. In the school's "Teaching Star" selection activity this semester, when I attended "The Enlightenment of Dripping Water wears away the Stone", the task of looking up celebrity information was designed on the study guide, and the students were very interested, including collecting famous sayings and drawing pictures. When communicating in class, the students were very enthusiastic and listened carefully, which was much better than what my teacher said alone. 3. Homework before class doesn't have to be arranged before class. Most of the homework before class can be finished by students in advance, and teachers can assign one or two homework in class according to the teaching content. The reason why students are required to study actively is that every child should come into the classroom with a prepared mind. Our classroom teaching should not only have homework before class, but also discuss the results. Classroom learning should be carried out according to certain planning procedures and roughly preset paths. When necessary, the pre-study content will be naturally introduced into the classroom, and after the classroom research and discussion are completed, full communication will be made to promote new understanding. Only in this way can we really improve students' ability. 4. The arrangement of homework before class should be carefully designed and arranged according to the actual situation and individual differences of students, according to the three levels of high, middle and low, so that students at different levels can complete exercises suitable for their own difficulties, find their own positioning and self-confidence, and let each student gain something. After the homework is completed, the class should establish a supervision system, and the team leader can be responsible for the homework. Groups can check and correct each other, and teachers can check and correct at random to ensure the quality of the homework. Preview homework plays a very important role in "student-based classroom" teaching and is an important embodiment of "student-based classroom", but we must clearly realize that preview homework is not the only embodiment of "student-based classroom", and the classroom with preview homework is not necessarily a "student-based classroom". Without homework before class, the teacher can take this class.
