For parents of junior high school students: What should you do in order to quickly adapt to the math learning in junior high school?(b).
Let's listen to Mr. Zhong's specific suggestions:
(1) Face reality and believe in yourself
The results are temporarily ahead, but they take the first step, you can take every step solidly, you will go faster and faster, and it is only a matter of time before you catch up. No one can affect your pace, only yourself, do you want to, dare to move forward?!
(2) If you have calculations, you can get the world of mathematics
Whether it is a legendary scholar or a god, in fact, they are all causes"Fast and accurate calculations"Practiced!
Therefore, Mr. Zhang especially hopes that the children must spend some time to strengthen their calculation during the holidaysIf you start learning calculations soon after entering school (about a week), you must be careful, be cautious, be careful, and strive to achieve "perfect" numeracy and "conditioned" muscle memory. With this ability, the study of mathematics (even physics and chemistry) will be overwhelming in the future, and there is no reason why mathematics results are bad
Of course, in order to achieve the above goals, good calculation habits are the key to success, the necessary quantitative timing training must not be less, remember: calculation is only right and wrong, only fast and slow, there is no "carelessness is not serious", you need to be particularly strict with yourself, you must not make any excuses for your own slow calculations, mistakes, and the teacher can not help "back" - what to say that is just careless and not serious, pay attention next time...., otherwise it will only pay a more painful price, and the effect may not be ideal, how can it be so easy to change the preconceived bad habits?
What are the good computing habits?How to cultivate?Mr. Zhang suggests that you read the following article (click directly on the text to open), maybe you will have a deeper understanding!
(3) Practice makes perfect, and the road is familiar
The only difference between good students and poor students is that for the same knowledge point, some children only need to practice 3 (times) to master it proficiently, while some children may need 5 questions (times), if they do not complete the required amount, the result: whether it is a good student or a bad student, it will only become worse or worse;When the required amount is reached or even exceeded, it must be the result that the good is better, the bad is better, and then the best.
In fact, this is also the reason for the formation of poor students, slow, lazy, cutting corners, the result of long-term formation, if this link is reformed, the results will naturally slowly improve.
(4) Dare to challenge and face tenaciously
The problem is not terrible, the terrible thing is: dare not face it!When you make efforts and bravely face all kinds of difficulties and challenges, even if you feel that you have gained nothing, in fact, the process itself is the greatest gain, this kind of experience is not given to you by anyone, this is the most fulfilling experience and feeling, the most precious wealth of knowledge, when the truth is revealed, you will find that you are actually not far from the truth......
In life, there are some things that we can often do better when we don't know how difficult it is, which is what people often call the ignorant fearless(Gauss, the prince of mathematics, quotes).
The power of suggestion is immeasurable, you can open your mind and boldly hint at yourself, and please "don't be stingy with your praise and encouragement"!
It is true that the teacher's casual words (such as: you can't do it anyway, don't waste time) may change a child's life, or it can destroy a childPlease don't easily deny your child's ability, maybe your critical eyes and ruthless statements will cause immeasurable damage in his heart, and your words of praise will also have an unexpected effect, this is the power of suggestion.
Fourth, how to learn, the highest efficiency, the best effect?
Every child, from primary school to junior high school, has changed a role, identity has been different, with the growth of age, learning methods, thoughts (consciousness) and cognitive ability should of course change, the angle and depth of thinking about the problem will inevitably change, if you continue to treat junior high school learning with the ideas and methods of primary school, the benefit will inevitably be low, the effect is certainly not ideal. At the same time, with the requirements of national policies for educating people, if you do not adapt to the learning methods and the latest ability requirements of junior high school, you will only feel difficult on the way to learning, and you will slowly fall behind, and then lose confidence.
According to the latest curriculum standards formulated by the state, every child should have a certain reading ability and self-learning ability in the future in order to meet the needs of social development
So, what is advanced self-learning?What kind of children can be self-taught?When should I start self-study?How does it work during the normal study period?How to learn on your own in advance?What should I do if I encounter difficulties in the process of advanced self-study?......
5. How to select and rationally use the materials needed for advanced self-study
Materials needed in advance: textbooks and corresponding synchronous exercises (basic training and reinforcement improvement, temporarily selected according to their actual situation).
6. How should parents cooperate in the process of advanced self-learning?
Seventh, establish a sense of the overall situation, in order to "stand high and see far".
When learning each knowledge content, you should consciously take a long-term view, which will have a profound impact on future learning.
The following is a case study for a detailed analysis
For example, in the first lesson of junior high school mathematics (positive and negative numbers).
(1) Broaden the awareness of practical application and cultivate the ability of reverse thinking
In addition to the need for children to understand that the introduction of negative numbers is due to "need", thinking from the perspective of learning mathematics, if they can understand a positive or negative number from the perspective of "change" of the "big picture", it will make children have a "suddenly open" vision.
For example, if the income is 3 yuan, it will be recorded"$3", then"What does "-2 yuan" mean?In this question, if "-2 yuan" is abstracted, what else can it represent?What about changing to other units?If "-2" is abstracted, what can it represent?Further, what if it is "-100 yuan", "100", etc.?Further, what is the practical meaning of "income-2 yuan"?
(2) Understand a number or quantity from the perspective of change, and cultivate children's dynamic awareness
Looking at a number or a quantity from a changing perspective, understanding a number or quantity from different angles, and understanding the relationship between "number and quantity" from the perspective of "movement" will help to quickly adapt to related dynamic problems in the future.
As above, "-2 yuan" is based on what circumstances (i.e., under what circumstances is "0 yuan" at this time)?What is the result when the meaning (or position) of "$0" changes?
(3) Enhance the awareness of letters (i.e., exchange of yuan) and cultivate the overall exchange of ideas
The conversion and sublimation of numbers and letters, primary schools have already had a certain experience, and at the same time it is an important support for follow-up knowledge learning.
For example, the "yuan" in the above "-2 yuan" is replaced by the letter a, what is the meaning?Let the children understand and realize the meaning of a in different meanings: the letter a is omnipotent. Again, what if "a+b" was used instead?
Another example: if a represents a negative number, then -a represents what number?If -a is negative, then what is a?If a is a positive number, then -a is what number?If a is a positive number, then -a is what number?(It seems to be beyond the knowledge of this section, but in fact it is not, and it can be thought of from the perspective of "practical problems").
(4) Use the classification of rational numbers to strengthen the classification standards and infiltrate the classification ideas
Clarify the classification of rational numbers, understand the meaning of classification and the method of classification, based on different criteria, classification is different. It is important for children to understand under what conditions each classification is based onWhat is the basis for the classification?What do I need to pay special attention to when classifying?What kind of "subordinate" relationship does each category in the taxonomy have?
After explaining the above content, it is worth giving this example: Is 2 a rational number?Is it a positive number?Is it a fraction?Is it an integer?Is it a non-negative integer?Since it is a positive number, it is an integer?......and so on, and also let the children try to write a number, and also set their own questions and answer them in the same way.
Another example: Please write two positive numbers, which are positive integers and positive fractions. What if the symbol of each number was changed to "-".What has it become?What if these two numbers were replaced by "letters"?
(5) Strengthen the awareness of symbols and adapt to the learning of junior high school mathematics as soon as possible
At the beginning of learning rational numbers, many children are very uncomfortable with the "-" in negative numbers, and they lose it at every turn, which is a normal phenomenon, and the length of adaptation time is different for each student, but if the symbol awareness is strengthened at the beginning, it will be adapted as soon as possible, which is obviously very beneficial to the subsequent operation and learning of rational numbers. As for how to strengthen?It varies from person to person, and personal feelings: teachers or parents should treat it as a "big" thing, and let children understand that this is a big problem, not a problem of carelessness and lack of seriousness, but a matter of habit, and there is no room for mistakes, and there is no reason for mistakes!
(6) Pay attention to the format and routine requirements of problem solving, and cultivate strict and good study habits
Good study habits include: problem-solving habits, usual homework habits, lectures, homework corrections, preview or review habits, etc., the good ring of learning habits directly affects the follow-up learning, not a little arbitrary, be sure to show the "overall situation" of the habitual view, otherwise: the difference is a millimeter, a thousand miles away.
