Senior 1 Chinese, Mathematics, English, Physics, Chemistry, Summer Training Knowledge, Learning Meth

The main thing is to choose the subject that you are interested in learning, which will be easier. However, there will be a relatively large number of science students who are admitted after the college entrance examination. Chinese、English, it all depends on your previous foundation,I feel that there is not much room for improvement,The main thing in science is to ask if you don't understand,And to be timely (don't think that every teacher or predecessor has been emphasizing this.,But I don't try it if I feel that it doesn't work.,I'm a person from the past.,The effect is very good.。

If you can, you can try to force yourself to ask at least one question to the teacher every day, in fact, Chinese and English can also be improved in this way. There is also a need to be good at sorting out knowledge points, and it is best to learn to be linked to real life, such as physics and chemistry, which are very useful. Although it's a science subject, after you read it, you will find that there are still a lot of things to memorize, and you have to memorize them.

Buy a book on high school study skills There are methods to guide all the homework in it, and I think it's better to read a book than to ask questions here.

I'm going to be a freshman at the beginning of school, and I bought a high school version of "Tsinghua Peking University, Talking about Learning Methods", I think it's pretty good, you can take a look.

Hope mine can help you.

Like Lezhi Teacher's humor and spoken English is the trump card.

They have a lot of courses listed on the Internet for free trials, and you can go to audit the classes, learn grammar, and practice listening.

What's right for you is the best!! And learning theory does not mean easy, the sea of questions.

The physics thing, the most important thing to draw, a lot of known quantities come out of the graph.

Write down all the necessary formulas and move forward according to the known quantities, and you will find that the unknown quantities are becoming less and less.

If you don't know how to ask the question, you have to redo it yourself, [don't look at the answer when you do it].

To really understand, don't really understand, understanding has a relationship with understanding.

The second one, chemistry, isn't it? There are only 4 relations between the quantity of matter, and one can be transformed indefinitely.

The book is now changed to death. Chapter 3 of the chemical equations and ion equations should be written endlessly, will you?

It's not up to you, it's the time for the exam.

It's important to have a way to memorize, especially those that are easy to make mistakes and easy to use.

For example, 2naoh+2al+2h2o====2naalo2+3h2 is 22223

What 1221 1112 2623 Everything, remember it well, the exam room is very time-saving.

As for the FE chapter, it's more complicated. Distinguish between +2 and +3

3 only changes to +2 with substitution +3 reacts with KSCN to blood red, +2 does not change color, but is easily oxidized to +3

You have to be me, it's not easy to do it by hand

I'm the same, I don't know anything, I've done my best! But nothing will come back! What to do!

Basics, don't memorize, understand, I don't remember well, but chemistry is very good, first remember the periodic table, the rest is to understand, in fact, chemistry is the simplest, mathematics and physics are abstract.

First of all, you have to understand first, ask the teacher if you don't understand, do more questions, master various question types, and it should be about the same...

In redox reactions, it is important to understand the direction and number of electrons. The commonly used methods are the double-line bridge and single-line bridge method, as well as the following formula: rise and lose oxygen, drop and return, which means:

Elements with increased valency lose electrons during the reaction and are oxidized; Elements with decreasing valency get electrons during the reaction and are reduced. As long as you memorize this mantra and practice it a lot, then there is nothing wrong with the redox reaction.

You should do more self-induction and summary, and the knowledge memory that comes out of your own thinking will be the most profound.

I. Formulation of the problem.

Senior 1 Chemistry is a senior high school education after the third year of junior high school chemistry education. Chemistry is an important part of students' learning of basic chemistry, and the quality of students' learning at this stage directly affects whether students can continue their studies. Students who have just entered high school are often not suitable for the study of high school chemistry due to the influence of the teaching methods of junior high school teachers, their own learning methods and some other factors, and even affect the learning of other subjects.

As both students and teachers, it is necessary to carefully analyze the influencing factors and take corresponding countermeasures to improve the quality of learning chemistry knowledge on a large scale. There are many reasons why freshmen have difficulty learning chemistry!

2. Causes of learning difficulties.

Reasons for teaching materials.

The basic knowledge involved in junior high school textbooks is not strong in theory and not high in abstraction. Compared with junior high school textbooks, the depth and breadth of high school textbooks have been significantly deepened, the characteristics of the development from description to reasoning have become more and more obvious, the horizontal connection and comprehensive degree of knowledge have been improved, the research questions often involve the essence, and the leap from visual thinking to abstract thinking has also appeared in the ability requirements. Some contents such as:

Redox reactions, ionic reactions, quantities of matter, periodic laws of elements, and other knowledge are highly theoretical and abstract, and these contents have always been regarded as the key knowledge that causes students' differentiation and learning difficulties.

Teacher's reason.

Due to the short learning time of chemistry in junior high school, teachers focus on instilling knowledge and grasping progress to students, but do not pay attention to the cultivation of students' abilities, resulting in high scores and low ability. The general knowledge introduction and selection part are not covered, resulting in knowledge deficiencies; Junior high school textbooks change frequentlyHomework stage: The after-school homework and problem-solving process of chemistry also have their own rules:((The fields involved in chemistry are too extensive.

Such as: spacecraft to the sky, landing on the moon, planets.
