Reflections on Junior High School Mathematics Classroom Teaching
. Induction is a very important part of mathematical thinking and mathematical ability, and the form of "operational conjecture" plays a more wonderful role in cultivating students' inductive thinking and ability. For example, A: B: C = 7: 5: 3. We can set A = 7K, B = 5K and C = 3K, but students don't understand. Let A = 3K and C = 7K. Let me give you an example: father: brother: sister = 7: 5: 3, which is easy to understand.
Second, citing examples of mathematics in life, creating situations, stimulating students' learning motivation, guiding students to have good interest and motivation in mathematics, and getting happiness and enjoyment in mathematics learning are our goals. Creating situations through practical problems in life can satisfy students' psychological needs for external novelty and make them feel curious and excited. At the same time, the abstract mathematical knowledge and students' thinking process are concretized and visualized by using practical examples in life, so as to highlight key points, break through difficulties and stimulate students' motivation and desire to learn.
Teaching reflection
Reflection on Math Classroom Teaching in Junior Middle School (). For example, the inverse proportion function: 80 fish, 2 cats, 40, 4 cats per cat, 20, 8 cats per cat, 10 per cat, X cats eat, and Y is the inverse proportion function of X.
Thirdly, in teaching, we should use mathematical knowledge to explain some common phenomena of human beings and nature, so that students can feel the universality and value of mathematical application. Mathematics learning should be realistic, meaningful and challenging, which is conducive to students' active observation, experiment, guess, verification, reasoning and communication. Hands-on practice, independent exploration and cooperative communication are important ways for students to learn mathematics. Some examples related to mathematics in life are listed in the compilation of the new textbook. On this basis, teachers can further observe life and collect materials to provide students with some more interesting and valuable examples. Students can explain many phenomena in human social life and nature from the perspective of mathematics, which can make students realize the close relationship between mathematics and nature and human society and understand the value of mathematics, thus enhancing their understanding of mathematics and confidence in learning mathematics well.
Fourthly, in teaching, we should apply the knowledge of mathematics to solve practical problems in life, so that students can further realize the important role of mathematics in human social life, realize the joy of success and the value of mathematics, and understand that knowledge is not only obtained in class, but also obtained in colorful life and social practice, thus breaking the mathematical theorem without feelings, cold mathematical formulas and mathematical symbols without souls. Students can really realize that everyone should learn valuable mathematics and get the necessary mathematics.
