Junior high school training operation is actually a deductive reasoning process, and operation is reasoning. In the elementary mathematics stage, mathematical operations are mainly four operations, namely algebraic expressions, rational formulas, radical operations, exponential, logarithmic and trigonometric functions. In the advanced mathematics stage, there are limit operation, differential and integral operation, vector and matrix operation, data and information processing and probability operation.
Mathematical operation ability includes:
Ability to operate in all these areas. To cultivate the above-mentioned operation ability, students should first master the relevant knowledge of various operations (such as the concept and nature of the object to be operated, the definition and rules of operation, etc.). ). In the process of operation, all the above factors must be fully and fully trained. The content of operational ability is also developing.
With the popularity of calculators, middle schools no longer need to learn four-digit mathematical tables and do more numerical calculation training with multiple digits, but need to cultivate the ability of estimating and processing a large number of data. Moreover, due to the use of program calculators and even computers, more and more complex operations can be guaranteed by programs.
At this time, students need to learn programming or algorithmic languages to gain the computing power to use them. When knowledge is transferred to the skill stage, students should be clear about the calculation goal, calculation steps and the intention of each calculation step.
