Importance of preview before math class (1)
Preview before class, as one of students' learning routines, is the first link in the learning process. From a psychological point of view, preview is a psychological preparation process for learning. There is an old saying in China: "Everything is established in advance, and it is abolished if it is not foreseen." This sentence emphasizes that no matter what you do, you should make full preparations in advance. Cultivating students' preview habits and improving their preview ability is an important way for students to learn to learn. Mathematical knowledge is continuous and uninterrupted, and there is a close relationship between old and new mathematical knowledge. These characteristics determine that mathematics learning should be based on students' existing knowledge and experience. It can be seen that preview before class is essential.
1, preview before class can improve the efficiency of classroom teaching.
Pre-class preparation can make students ready for new knowledge. Teachers can get to know what they don't understand in class before class, so that the effect will increase obviously when they come into class with questions and attend classes aimlessly. Through preview, students have a certain understanding of what they want to learn, internalize some easy-to-understand and interesting contents, and have doubts and questions. In class, students ask questions and teachers and students discuss them together. This not only saves unnecessary teaching time, gives students more time to explore, but also arouses students' interest in learning and desire to solve problems, makes lectures targeted and prepares them psychologically for mastering new knowledge. When students preview, they mark all the things they don't understand. In class, you will take the initiative and focus on the classroom; After reviewing students' homework, teachers find that students are more concentrated and typical, and they will also teach students in a targeted manner. So as to improve classroom efficiency.
American psychologist Ausubel said: "The most important reason that affects learning is what students already know. We should teach according to students' original knowledge. "Pre-class preparation can help students clear learning obstacles in advance, build a bridge between old and new knowledge, and narrow the distance between students and new knowledge.
2. Preview before class can improve students' self-study ability.
Preview before class is to let students learn by themselves and find solutions to problems through self-study. What teachers can teach students at school is only the most basic knowledge. A lot of new knowledge depends on students' continuous exploration in future study and self-study as needed. Therefore, it is of great significance to cultivate students' self-study ability from an early age. Preview is a necessary step in the transition to self-study.
Through preview, students are provided with a stage to cultivate their self-study ability. In preparation, students will try their best to collect existing knowledge and experience to understand and analyze new knowledge. This process is precisely to train students' ability to learn independently, ask questions and analyze problems. Over time, students' self-study ability will gradually improve.
3. Preview before class can cultivate students' independent character.
Under the background of the new curriculum reform, cooperative learning has become a new way of learning, but the independence of students can not be ignored. Let students master certain knowledge through their own preparation, and they need to find their own solutions to problems, not relying on others for everything, but also relying on themselves! This has a certain effect on cultivating students' independent personality. Now, some children live in a sweet environment. Parents seldom let their students do a difficult thing alone, but always do it instead of them. Children lack self-awareness and don't realize their own value. We might as well let students learn by themselves and let children experience setbacks and happiness in preview, which will play a certain role in improving their personality.
4. Preview before class can stimulate students' interest in learning.
In teaching, there are often some students who are slow to accept, and it takes some time to digest and absorb the content explained by the teacher. However, some students find it difficult to learn the knowledge behind because they don't fully understand the previous knowledge, and thus gradually lose interest. After previewing before class, these students have mastered the knowledge they want to learn through their own learning and understanding, and have some sense of success. This sense of success urges him to show his learning achievements, he will actively participate in classroom discussions and ask questions, and he will have confidence in his study and himself. After a long period of persistence, I naturally no longer find mathematics difficult to learn and became interested in mathematics learning. "The higher the freedom of learning, the higher the degree of physical and mental involvement, and the higher the interest." It can be said that a truly quality preview can not only greatly improve students' interest in learning, but also cultivate and improve students' mathematical thinking ability, emotional attitude and values. Under the new concept of the new curriculum, preview should be endowed with new connotations. We should regard preview as preparation for classroom teaching. It means that students preview with their own experiences and backgrounds, and have their own unique experiences and feelings, which makes classroom communication more full and profound. More "generative" content may be formed in the classroom through preview.
Preview under the new curriculum concept should be given new life. As an autonomous inquiry learning activity for learners in front of classroom teaching, it not only prepares students for learning, but more importantly enables students to acquire important mathematical knowledge, learning experience and basic mathematical thinking methods and skills in the process of autonomous inquiry, initially learn to use mathematical knowledge to solve mathematical problems in daily life and study, and cultivate initial innovative spirit and practical ability. In order to promote students' learning and achieve all-round development, we should also think about how to prepare well before class.
The Importance of Preview before Math Class (2)
I benefited a lot from several months of training. I learned a lot through studying, communicating and asking questions. According to the preset topics in the room, I study hard on the internet and collect information extensively; From this I understand that preview is the first step for students to accept classroom teaching. With a good habit of preview before class, students can have initiative and creativity in their study, better cooperate with classroom teaching and improve the quality of classroom teaching. Preview is not simply reading textbooks, but an activity to preview new textbooks according to the established plan, which is the starting point of the next day's study. Through this study, combined with the usual teaching practice, I have the following views on students' preview before class:
First, preview before class can improve the efficiency of classroom teaching. When students preview, they will know something about what they will learn the next day. When the teacher explains, he will recall what he learned in the preview, especially what he didn't understand in the preview, which will become the part that students pay attention to, so that he can actively and emphatically concentrate on listening and learning, thus effectively improving classroom efficiency.
Second, preview before class can stimulate students' self-confidence. In teaching, there are often some students who are slow to accept, and it takes some time to digest and absorb the content explained by the teacher. Because these students do not fully understand the previous knowledge, it is difficult for them to learn the latter knowledge and gradually lose their confidence in learning. After the preparation before class, these students have mastered the knowledge they want to learn through their own learning and understanding, which makes them feel successful. This sense of success will make them want to show their learning achievements, so that they will actively participate in classroom discussions and ask questions, which will make them full of confidence in their studies. After long-term persistence, I naturally no longer feel that mathematics is difficult to learn, and I gradually became interested in mathematics learning.
Thirdly, preview before class can improve students' self-study ability. When students preview, they first read a book to complete the exercises after the book. When students can't solve exercises, they will carefully look at examples, compare examples with exercises, think about the old and new knowledge needed to solve examples, collect existing knowledge and experience, and choose appropriate methods to understand and analyze knowledge. After practicing for a long time, students will gradually master the self-study methods in preview, integrate what they have learned and learn to draw inferences from others. Form the framework and network of knowledge, lay the foundation for completing the knowledge transfer from old to new, from shallow to deep, from simple to complex, from concrete to abstract, and gradually learn new knowledge actively and efficiently.
To sum up, I know the importance of students' preview before class. It is not easy for students to preview independently. Most primary school students have poor autonomy and will not preview the text every day; As teachers, we should not rush for success. We should give selfless help-that is, teach them to preview their learning methods. For the preview results, teachers should establish a scientific and reasonable evaluation mechanism to reward the excellent and punish the poor.
In short, it is every teacher's unshirkable responsibility to let students learn mathematics well and effectively guide them to preview before class.
