Solution of Triangle Formula in Senior Two Mathematics
Mathematics learning method in senior two
Grasping the foundation is the key
Mathematical exercises are nothing more than the comprehensive application of mathematical concepts and ideas. Understanding the basic concepts, theorems and methods of mathematics is the premise of judging the type of topic and the scope of knowledge, and the basis of correctly mastering the method of solving problems. Only when the concept is clear and the method is comprehensive, can we get a solution quickly when we encounter a problem, or when we face a new exercise, can we associate the method of the exercise we have done at ordinary times and realize a quick answer. Knowing the basic theorem is the premise of solving exercises correctly and quickly, especially the review of chapters such as solid geometry. Being familiar with the basic theorem and mastering it flexibly can make the answers to the exercises clear and logical. On the contrary, it will make the problem-solving slow, logically chaotic and unclear.
Guard against maritime tactics
Doing problems is to consolidate knowledge and improve adaptability, thinking ability and computing ability. Learning mathematics requires some exercises, but learning mathematics does not mean doing problems. In all kinds of exam questions, a considerable number of exercises can be solved through the accumulation of simple knowledge points and the deduction of axiomatic knowledge system These exercises are to expand the problem-solving methods by doing a certain amount of exercises. But with the reform of the college entrance examination, the college entrance examination has focused on the examination of creativity and ability. So do the exercises carefully, pay attention to the understanding and flexible application of knowledge. When you finish an exercise, don't ask yourself: What knowledge points did this question examine? What method? What solutions do we get from it? What are the commonalities in solving this kind of exercises? What kind of problem-solving strategies have I applied to realize the complete solution of the problem? Only in this way can we cultivate our understanding and creativity and develop our creativity. There will also be scientific methods to solve those comprehensive problems in the upcoming final exam and future college entrance examination.
Big thinking of inductive mathematics
The main purpose of mathematics learning is to cultivate our creativity and our ability to deal with things and solve problems. Therefore, when dealing with mathematical problems, it is particularly important to master big strategies and big thinking, and we should pay attention to summing up in our usual study. Usually in class, a knowledgeable student should listen to the teacher's analysis and induction of the topic. However, there are still many students who don't pay attention to the teacher's analysis and often remain calm during every step of calculation and deduction explained by the teacher. Listening to the class is very serious, but it is very laborious. After listening, it's all a calculation process, fragmented. The teacher's analysis is to guide students to think and inspire them to design big strategies and big thinking to deal with these problems. When the teacher answers the exercises, students should use their own calculations and reasoning to know what the teacher is going to do. In addition, giving the answer to the question does not mean that the answer to the question is over, but it takes some time to sum up and carefully summarize the memory. All these problem-solving strategies should be brought into your mind, become a permanent memory, and become your own experience and skills to solve such problems. At the same time, it also solves the bad problem that students can attend classes but can't do problems.
Accumulate examination experience
There is a big exam at the beginning of each month this semester, and each unit has more than a dozen unit exams and mock exams. Seize these opportunities, accumulate certain examination experience, master certain examination skills, and give full play to their due level in the examination. In fact, the examination is a single-soldier battle, and it is a battlefield to test a person's comprehensive ability such as endurance, acceptance and problem-solving ability. These abilities can only be cultivated and trained in the usual exams.
Math learning skills in senior two.
Cultivate a strong interest
High school mathematics is characterized by abstract concepts, many exercises and high teaching density. Therefore, after the first year of high school, some students are afraid of mathematics.
In fact, it is not difficult to learn mathematics. The key is whether you are willing to try. When you dare to guess, it shows that you have mathematical thinking ability; And when you can verify the conjecture, it means that you have a talent for learning mathematics! Seriously study senior two mathematics, what you can understand is: how to make objects that meet the requirements with the least materials; How to allocate resources and put them into production to get the maximum profit; Why beautiful curves can be associated with algebraic equations; Why it is much easier to have a car accident than to win the sports lottery; Why do classes in a year often have the same classmate from Amanome?
When you are fascinated by mathematics? Trap? After that, you have begun to take the first step to learn math well!
Cultivate the ability of analysis and reasoning
Actually, mathematics is not intellectual. It is an empirical discipline, but it is a thinking discipline, and high school mathematics fully embodies this feature. Therefore, mathematics learning focuses on cultivating the ability of observation, analysis and reasoning and developing learners' creative ability and innovative thinking. So in the process of learning mathematics, we should consciously cultivate these abilities.
The relationship between learning methods and grades can be described as follows: when you are willing to understand the answers to some questions, your exam results should be easy to pass; When you are keen on studying all kinds of questions and making regular summaries, you must be an excellent student in class mathematics; And when you are used to doing your own problems and solving them according to the definition of mathematics, your mathematics level can already keep pace with the teacher!
Try these learning methods.
Students with different learning levels need different learning methods.
If you are worried about the low state of mathematics learning, please follow the following requirements: after previewing, you can get twice the result with half the effort by coming into the classroom with questions; Doing beautiful homework is ignorance, and it is more reasonable to make serious corrections if you do something wrong; Isn't the exercise required by the teacher? Topic sea? Please finish it carefully. If a genius can learn math well with fewer words, it's not you. In the exam, the correct rate is as important as the speed of doing the questions, but giving up some questions reasonably can help you play your normal level.
If you are depressed because of the slow progress in mathematics, please accept the following suggestions: collect the wrong questions you have done, correct and write down the reasons for the mistakes, which are your personal wealth; For exam results, set yourself an acceptable bottom line and a goal within your power; Reasonable schedule and good study habits will help you get stable academic performance, so please make a good study plan and stick to it; If you spend a lot of time on a subject, you'd better allocate your study energy to each subject reasonably. People's learning in a certain knowledge field often appears? Plateau phenomenon? In other words, when we reach a certain level and work harder, the progress is not obvious at first.
