First, I am committed to seeking a shortcut to learning, today I will find a set of 60 formulas summarized by Haidian famous teachers, and tomorrow I will buy a set of 30 formulas summarized by Huanggang senior teachers, and I think that everything will be fine if the child learns these.
Second, blindly brush the questions, through various channels, all kinds of exercises, dense papers to let the children brush, there is no pertinence at all, the child is soaked in the sea of questions every day, in fact, the progress is not big, there are too many invalid components.
Third, blindly follow the trend, go to some famous, propaganda in place of tutoring institutions, think that the money is spent in place, the grades will go up, tutoring institutions generally in order not to let the students' parents spend their money in vain, each class will talk about a large number of knowledge points, the classroom can not be digested at all, and some knowledge points are relatively deep, to put it bluntly, it is ahead of learning, such as the hourglass model of the fifth grade of the tutoring class, in fact, it is a similar triangle of the eighth grade, students learn a little understanding, but it is easy to dispel enthusiasm.
Learn mathematics must first study the concept, don't think that mathematics is to do problems every day, fairness is natural, mathematics is the most rigorous discipline of logic, the so-called famous teacher's experience and skills are of course useful, but that is useful after figuring out the concept, simply memorizing the formula is to drink poison, after the concept is clear, the formula will naturally be remembered, and remember it firmly, brushing the problem is also to learn the concept first, find the unclear place, targeted brushing, the relationship between the concept and the skill is like letting you move bricks, and as a result, you go to move cement and sand, This is a concept of unclear, no matter how much you do, it is useless, and the skill is the relationship between you moving bricks with your bare hands and pulling bricks with a car, both are very important, but there is a concept first, skills in the back, and you can't put the cart before the horse.
