How to test 1 full mark for multiple-choice mathematics questions in college entrance examination? Some multiple-choice questions are adapted from calculation questions, application questions, proof questions and judgment questions. This kind of problem can directly proceed from the conditions of the problem, use the known conditions, related formulas, axioms, theorems and rules, and draw the correct conclusion through accurate operation, rigorous reasoning and reasonable verification, so as to determine the selection method.
2. Screening method. The essence of solving multiple-choice questions in high school mathematics is to get rid of the false and keep the true, abandon the wrong answers that do not conform to the meaning of the questions, and find the correct conclusions that conform to the meaning of the questions. We can narrow the choice by screening out some conclusions that are easy to judge and irrelevant, and then get the correct answer from the remaining conclusions. If there is only one conclusion after screening out the problems, it is the option.
How can we improve the math scores of senior three? 1. First of all, it is best for students to preview the contents of the textbook briefly before each class, have a general understanding of the knowledge points to be learned, and mark the places they don't understand when previewing, so as to facilitate students to ask questions in class and effectively solve students' learning problems.
2. Secondly, students must take notes frequently in class and "take the essence and discard the dross" according to what the teacher said. For solving mathematical problems, sometimes you can't just rely on your brain. Only through careful written calculation can we find the difficulties, master the solution methods and finally get the correct calculation results.
3. Then, after class, you must practice and consolidate what the teacher said, and repeat the examples in class several times. Strengthen after-class exercises. Besides homework, find a good reference book and do as many exercises as possible (especially comprehensive and applied questions). Practice makes perfect, thus consolidating the effect of classroom learning and making your problem solving faster and faster.
4. Learning mathematics should be good at summarizing and classifying, looking for the * * * relationship between different questions and different knowledge points, and systematizing the learned knowledge. To give a concrete example: in the function part of senior one algebra, we have studied several different types of functions, such as exponential function, logarithmic function, power function, trigonometric function and so on. But comparing and summarizing, you will find that whatever kind of function we need to master is its expression, image shape, parity, increase and decrease and symmetry. Then you can make the above contents of these functions into a big table and compare them for easy understanding and memory. Pay attention to the combination of function expressions and figures when solving problems, and you will certainly get much better results.
