Keywords: junior high school mathematics teaching; Cooperative inquiry teaching; Application strategy; Mathematical reasoning ability;
With the development of science and technology, society needs more and more intelligent talents. As an important basic subject in junior high school, junior high school mathematics can cultivate students' intelligent thinking ability. In recent years, the traditional junior high school mathematics teaching model has appeared various drawbacks, which can no longer meet the needs of current social development. Cooperative inquiry teaching method came into being in this situation. Then, how should junior high school math teachers skillfully use cooperative inquiry teaching method in class and constantly optimize it? The author will discuss this issue, hoping to help the teaching of junior high school mathematics teachers.
First, the application analysis of junior high school mathematics teaching mode
In recent years, the development of information age and the improvement of scientific level have put forward higher requirements for the reform of junior high school mathematics teaching mode, and the teaching of junior high school mathematics teachers is also facing great challenges. Junior high school mathematics plays an important role in cultivating students' mathematical thinking and related logical reasoning ability. The exertion of these roles requires teachers to innovate classroom teaching mode and conduct correct and effective guidance. However, at present, many junior high school math teachers still have many disadvantages when using related teaching models.
1, bound by the traditional teaching mode.
At present, most junior high school mathematics classes still stay in the traditional mathematics teaching mode. In mathematics classroom, teachers are often in the main position, controlling the initiative of the whole class, while students are in a passive position, mechanically accepting classroom knowledge, relying on teachers' classroom teaching, and lacking individual independent thinking. This teaching mode is not conducive to giving full play to students' subjective initiative and affecting students' classroom learning efficiency.
2. The classroom atmosphere of mathematics teaching lacks vitality.
In the traditional junior high school mathematics classroom, teachers are only responsible for teaching textbook knowledge on the podium, and students passively accept the knowledge instilled by teachers in the classroom. This kind of teaching method suppresses students' creativity and enthusiasm in learning to a certain extent, which makes the mathematics classroom atmosphere lack of vitality. After a long time, students will get bored with junior high school mathematics, thus forming a negative learning mentality, which is not conducive to the reform and innovation of junior high school mathematics classroom teaching mode.
Second, the application strategy of cooperative inquiry teaching method in junior high school mathematics classroom teaching
As far as junior high school mathematics teaching content is concerned, there are many formulas and theorems in mathematics textbooks, which require teachers to guide students to sort out knowledge points and connect useful knowledge into a network structure to form a complete knowledge framework. Therefore, teachers' classroom instruction plays a very important role in students' mathematics learning. As far as cooperative inquiry teaching method is concerned, teachers need to constantly guide students to explore problems in depth, and solve various problems through inquiry in the process of cooperative learning, so as to promote students to continuously improve their learning efficiency within limited classroom time.
1, cultivate students' sensitivity to numbers.
Learning mathematics, a very important point is the sense of number, which is an important content of mathematical thinking. Junior high school math teachers should pay attention to classroom teaching methods and cultivate students' interest in mathematics. For example, in the teaching of rational numbers and irrational numbers, teachers can cultivate students' sensitivity to numbers by comparing the size of each number. After students master rational numbers and irrational numbers, teachers can teach them addition, subtraction, multiplication and division step by step. On the one hand, it can enhance students' sensitivity to numbers, cultivate students' feeling of new numbers, and also improve students' ability to understand the logical relationship between numbers.
2. Create an interesting classroom atmosphere through situational inquiry and cooperation.
Cooperative inquiry teaching method fully respects students' right to learn independently in class. Through independent inquiry and cooperative learning, students can give full play to their main role in mathematics classroom. For example, in the teaching of "plane rectangular coordinate system", teachers can judge the position of an object in the coordinate system by combining with the actual object, deepen students' memory, stimulate students' interest in learning, and thus enhance students' learning effect. At the same time, teachers can also set interesting questions and answers in class to guide students to actively participate in classroom teaching and enliven the classroom atmosphere, thus mobilizing students' enthusiasm and enthusiasm for learning.
3. Work in groups to explore and solve difficult problems.
In junior high school mathematics classroom teaching, cooperative inquiry teaching method is a more efficient and flexible classroom teaching mode. In view of the after-class exercises in textbooks or the problems in the classroom, teachers can divide the class students into groups, discuss and explore in groups, and solve problems in the process of cooperative exploration. For example, in the teaching of "front view, left view and top view", teachers can divide the class into three groups and set a topic that is slightly more difficult than students' level, such as drawing the front view of the object in the first group, the left view of the object in the second group and the top view of the object in the third group. Each group discussed and discussed separately, and sent group representatives to answer. This method can deepen students' understanding of textbook knowledge and consciously think independently, thus mastering textbook knowledge.
4. After group cooperation and exploration, reflect in time after class.
After the classroom problems are solved, teachers need to give students reflective homework after class. Through after-class reflection homework, guide students to think about the topics explored and discussed in class, "why should we solve it this way" and "what method should we use to solve it" when encountering similar topics in the future. In the process of reflection after class, students can gain experience and cultivate good mathematical thinking. In addition, teachers should also reflect on teaching after class, such as the completion of teaching objectives, the innovation of teaching content organization, the appropriateness of teaching methods, the rationality of teaching design, teaching ideas and methods. Constantly improve group cooperation and inquiry teaching methods, activate classroom atmosphere and improve classroom teaching efficiency.
Third, the research significance of cultivating students' mathematical reasoning ability
The traditional junior high school mathematics teaching model can no longer meet the development requirements of the present era. In the current junior high school mathematics classroom, there is an urgent need for innovative teaching models. Teachers should make the most suitable classroom teaching plan according to the actual situation of students, so as to maximize students' learning efficiency. The cooperative inquiry teaching method just meets the needs of educational reform. The biggest feature of cooperative inquiry teaching method is that it can respect students' dominant position in the classroom to the maximum extent and give students enough time to think independently and explore cooperatively. In the cooperative inquiry teaching class, students exchange knowledge with their classmates through independent thinking and taking knowledge as a bridge. On the one hand, it can cultivate students' interest in learning, stimulate students' enthusiasm for learning and improve students' efficiency in learning junior high school mathematics; On the other hand, it can strengthen the communication between students and between students and teachers, so that students can immerse themselves in classroom learning, fully display themselves in the classroom and enhance their self-confidence in learning. The junior high school mathematics classroom with cooperative inquiry teaching method is very different from the classroom under the traditional teaching mode. Classroom teaching is no longer a rigid blackboard writing, but an interesting learning journey between teachers and students, which can increase the fun of teachers and students, thus achieving a win-win effect.
Compared with the traditional mathematics teaching method, cooperative inquiry teaching method is a flexible and efficient teaching method. In the actual classroom teaching process, teachers need to organically combine teaching methods with the actual situation of students, adjust the cooperative inquiry teaching scheme in time and innovate the cooperative inquiry teaching method in view of the problems encountered by students in the learning process. In the process of teaching, teachers should find their own defects and deficiencies in time and make adjustments and improvements from reality; Teachers should constantly improve their professional quality, deepen the study of classroom content, tap the hidden thinking clues in textbooks, constantly update teaching content and innovate teaching methods; Teachers should also skillfully use cooperative inquiry teaching method and infiltrate it into junior high school mathematics classroom teaching. In short, we should keep up with the changes of the times, study and analyze the cooperative inquiry teaching method in junior high school mathematics teaching, so as to better serve the junior high school mathematics teaching cause.
