As we all know, it is very difficult to understand and solve problems in high school mathematics learning, which requires teachers to learn to use appropriate methods to implement teaching and explanation. One of the effective teaching methods is to create an interactive relationship between teachers and students in the classroom, so that students can accept knowledge more easily and naturally.
For example, when learning permutation and combination, many types and modes are complicated, and the calculation is relatively cumbersome, which makes it easier for students to lose their concentration. At this time, if teachers properly introduce questions and enhance interaction, they can achieve twice the result with half the effort. For example, Formula C refers to combination, in which R elements are selected from N elements without arrangement (that is, without sorting). Teachers can ask students to narrate together and demonstrate while doing exercises, thus creating an active classroom atmosphere.
Second, create an appropriate teaching situation
Besides classroom interaction, another effective teaching method is to create appropriate situations. For example, when learning solid geometry, many students' thinking can't be solid. However, if the teacher makes all the corresponding figures into props, cubes and cuboids into transparent models, and displays all the spaces that students usually can't see on the models, all kinds of invisible auxiliary lines will be clearer and students will understand them more fully.
Third, the combination of life and knowledge
High school mathematics comes from life and can be used in life. In order to make students more interested in high school mathematics, teachers can introduce life-oriented learning situations. For example, when learning linear programming, teachers can introduce planning objectives into their lives, such as football fields and lawns. Teachers can take this large-area graphics as planning objectives, so that mathematics can really enter students' lives, thus making students' understanding of mathematics more profound and easier. For another example, when learning space vectors, teachers can also take desks or corners as teaching cases, so that students can feel mathematical concepts more easily and improve classroom efficiency.
