Q: My son is in the second year of high school liberal arts at Nanjing Four-Star High School, and his math is about 60 points normal, but he has been unable to improve and is dying!
A: I can understand the parents' feelings. I would like to say two meanings: 1. There are three main factors that affect students' performance in high school (1) knowledge mastery, whether it can form a clear framework (what each knowledge point should be mastered, when to use, how to use) ;(2) computing experience and ability (basic calculation methods, such as solving equations, solving inequalities, exponential and logarithmic operations, quadratic function images and the direction and method of discussing images; identifying the direction of the question and correctly selecting formulas or theorems, etc.) ;(3) thinking habits and abilities ( Whether the thinking habits are reasonable, whether the problem can be related to knowledge, the condition and the conclusion; whether there can be a certain modeling ability).
2. High school exam about 60 points, judging from the students I have seen myself, the basic calculation should not be a big problem, and it is not the main shortcoming to want to calculate 100 points. The main problem is that the knowledge is not clear, no clear framework is formed, and the applicable scenarios of each knowledge point and the correct use method are not known, and the problem encountered is the fragmented memory obtained by ordinary lectures and practice; if there is no impression, the topic is based on trial and error (it can also be called Monty). Because the knowledge problem is not solved, the effect of brushing the problem is very poor: it is impossible to deepen the understanding and mastery of knowledge, it is difficult to effectively accumulate computing experience, and it is impossible to improve the thinking ability.
Tip: Try a new way of learning with a module (such as solving triangles and finding a list of knowledge on the headline number). 1. Memorize and write the knowledge list of the module; 2. Watch the relevant lecture videos and redo the example questions involved; 3. Do the corresponding part of the college entrance examination real questions. If it goes well, the exam for the corresponding module should be more than 110 points. However, at the beginning, there will be various mistakes, and the score of about 80 points is not a big problem. After a period of time (usually half a semester) there is hope of exceeding 100 points.
