How to organize math review for students with math learning difficulties in senior three?
1. Reasons for the formation of students with learning difficulties in mathematics

The reasons for the formation of "students with learning difficulties" in mathematics are as follows: first, mathematical knowledge is abstract, and many concepts and theorems highly summarize the same characteristics of some cases, leaving only some basic quantitative relations to form mathematical concepts. For example, the concept of derivative is summed up according to the * * * identity characteristics of the method of finding the slope of the tangent at a certain point on the curve and the instantaneous speed of the object when it is moving. If these two examples are put aside, it is difficult for students to understand the concept of derivative. Secondly, some students have not formed the habit of reviewing their lessons in time. In teaching, they often find the knowledge or problem-solving methods that they just explained yesterday. Today, many students can't answer the questions in class, which shows that students don't review what they have learned in time. The knowledge points of mathematics are closely related, and the latter knowledge is often based on the old knowledge. For example, the double angle formula in trigonometric function is derived on the basis of the sum formula of two angles, and the concept of derivative is derived on the basis of the concept of limit ... If you can't remember the previous knowledge, the later knowledge will be difficult to understand, so it is very important for students to develop the habit of reviewing their lessons in time. Thirdly, some students are eager for quick success and instant benefit in learning mathematics, and are afraid of difficulties. When learning mathematics, we just remember the conclusion, but don't study the ins and outs of the conclusion, so we can't really understand the mathematical knowledge, which leads to the inability to apply it flexibly to solve problems. For example, x1>: x2 > X3>0, then a=■, b=■, c=■, then the relationship between a, b and c is. When solving this problem, it is because most students don't really understand the straight line slope formula and can't solve it by combining numbers and shapes, which makes them feel helpless in front of this problem.

2. Guide students to learn high school mathematics well.

Create teaching situations, stimulate students' interest in learning, and pay attention to the formation process of mathematical knowledge. In order to attract students in mathematics class, teachers should first create a good mathematics teaching situation in the classroom, guide mathematics knowledge in combination with practical problems or stories in life, and stimulate students' interest in learning mathematics. For example, the average inequality comes from the lowest cost of rectangular pool, and the knowledge about geometric series comes from the story that the king of ancient India wanted to reward the inventor of chess, and so on. Secondly, when explaining mathematics knowledge, students should be guided to understand the ins and outs of knowledge, rather than simply memorizing conclusions. For example, when it comes to the double-angle formula of trigonometric function, let students know the derivation process of the double-angle formula, and let them know through examples that anything with a double relationship between angles can be applied to the double-angle formula.

After learning a new knowledge point, if you don't review it within a week, your knowledge will almost be forgotten. On the contrary, if you review regularly within a week, you will remember it for a long time. In order to let students form the habit of reviewing in time and often, teachers can adopt the method of "weekly test", that is, test once a week. The content of the exam can be the content of the last week or two. With the pressure of exams, students will be motivated to review in time. Over time, students will form the habit of reviewing in time, thus defeating the deadly enemy of forgetting. Of course, in the "weekly exam", the difficulty of the test questions should be controlled according to the actual situation of the students, so that most students can feel the joy of success and hard-won achievements, which will help them maintain their enthusiasm and interest in learning.

Give priority to encouragement and help students build up confidence in learning high school mathematics well. At present, many senior one students generally have a fear of mathematics. The reason is that they didn't lay a good foundation in junior high school, and failed exams again and again made them lose confidence in learning mathematics. Therefore, in the first stage of high school, math teachers should not only be good at extracurricular activities, but also be good at capturing students' bright spots, encouraging students more and restoring their confidence in learning math well. How to grasp the bright spot of students? It is through classroom questioning, homework, weekly test and other activities that students can discover various advantages (such as being able to answer questions correctly, writing neatly, solving problems in a novel way or solving more than one problem, improving their grades, etc.). ) and then further affirm the students. After receiving positive information from teachers for many times, students will gradually become interested in learning, their grades will gradually improve, their confidence in learning will be established, and learning mathematics well is just around the corner.
