It is every teacher's daily work to analyze and study teaching materials. Read through the contents of the "Mathematics Wide Angle" unit of the mathematics textbook published by People's Education Press at least once, and have a good idea of the guiding ideology and arrangement intention of the textbook. Textbooks can be surpassed and selected. In the way of dealing with teaching materials, teachers should be good at modifying, developing and creating the content of teaching materials in combination with local actual conditions.
Second, seriously understand the significance of "mathematical wide angle" arrangement
"Wide Angle of Mathematics" arranges logical reasoning, equivalent substitution and other contents to explore pure mathematical problems, and gradually penetrates some important mathematical thinking methods into students. Through observation, operation, experiment, speculation, reasoning and communication, they initially feel the wonder and function of mathematical thinking methods, are trained by mathematical thinking, and gradually form an orderly and rigorous thinking consciousness, and at the same time make them gradually form a sense of exploring mathematics.
Third, accurately locate the teaching objectives and requirements of "Mathematics Wide Angle"
The teaching goal of "Wide-angle Mathematics" is different from our regular mathematics courses and mathematical practice activities, so we can't blindly raise the requirements and turn "Wide-angle Mathematics" into an Olympic mathematics course. We can't blindly pursue the result of solving problems, or even stay in the intuitive experimental operation after a class, ignoring the process from intuitive to abstract, thus ignoring the perception of mathematical thinking methods, and the goal positioning is low. The orientation of teaching objectives should reflect the student-oriented level. In teaching, students should not be treated equally because of the different requirements of the starting point of learning.
Fourth, pay attention to preparing lessons before class and make full preparations.
Familiar with teaching materials and teaching reference books, and make clear the key and difficult points of teaching; Compilation of teaching plan: it is the implementation plan of classroom teaching, which determines the teaching focus, difficulties, time allocation, teaching methods, hardware use, student activities and so on. Is an important part; Prepare hardware: Instruments, equipment and teaching AIDS are important necessities, including audio-visual equipment, and optimize the teaching process with the help of multimedia.
