Math:

You can try to reason about the theorems in the textbook yourself. This will not only improve your proof ability, but also deepen your understanding of the formula. There are many exercises. Basically, after each class, you have to do after-school exercises (excluding the teacher's homework).

The improvement of math scores and the mastery of math methods are inseparable from students' good study habits. Therefore, good math study habits include: listening, reading, exploring and doing homework.

Listening: We should grasp the main contradictions and problems in class, think synchronously with the teacher's explanation as much as possible, and take notes when necessary. After each class, we should think deeply, sum up and make a lesson.

Reading: When reading, you should carefully scrutinize and understand every concept, theorem and law. For example, you should learn from others by connecting with similar reference books to increase your knowledge and develop your thinking.

Inquiry: Learn to think, explore some new methods after solving problems, learn to think from different angles, and even change conditions or conclusions to find new problems. After a period of study, we should sort out our own ideas and form our own thinking rules.

Homework: review before you do your homework, think before you start writing, and grasp a large piece of a class of questions. Homework should be serious and writing should be standardized. Only in this way can you learn math well.

In short, in the process of learning mathematics, we should realize the importance of mathematics, give full play to our subjective initiative, pay attention to small details, develop good math learning habits, and then cultivate the ability to think, analyze and solve problems, and finally learn mathematics well.

Geography:

As a discipline, the study of law has many similarities with other disciplines. Such as: scientific learning attitude; Use your head, hands and mouth frequently; Ears, eyes, mouth, hands, heart, etc. At the same time, it also has its own unique learning methods. In fact, what we have been emphasizing is scientific learning methods and thinking methods.

First, the soul of geography learning-the use of maps

1. The classification maps of the Institute include sunshine map, statistical map, topographic profile map, geological map, geographical landscape map, geographical schematic map, geographical cartoon map, geographical data map, geographical structure map and geographical contour map.

2, learn to look at the picture ① Look at the theme ② Look at the legend ③ Pay attention to the details ④ Connect with reality.

3. Learn to change drawings ① Tu Tu transformation (section to plan) ② graphic transformation.

4. Learn to use charts ① to summarize geographical laws or characteristics ② to remember.

Geography of China: You can look at these maps, namely: administrative map of China, topographic map of China, climate map of China (temperature and precipitation), water system map of China, and resource map of China (forest, minerals, hydropower, tourism resources, etc.). ), China's crop distribution map, China's industrial distribution map, China's population, nationality, city and commercial center map, China's traffic map, China nature reserve map, etc. Look at the pictures, remember them, or even draw them one by one, and you will have the basic knowledge of China's geography.

Learning world geography:

1. Work hard on ten lines (five meridians and five latitudes).

2. Find out the natural landscape and human landscape in the area where the Tenth Line passes.

3. Draw an outline map within the latitude and longitude span of no more than ten degrees, tell the location, natural geographical features and human geographical features, and ask why. In this way, you will find that you begin to have a "picture" in your mind and a "truth" in your heart, and geography is no longer a monotonous text.

Second, the pillar of geography learning-understanding of textbooks

1, according to the outline, master the geographical principles and laws.

First, read the book thick: make reading notes on the book to supplement your understanding or find out your doubts.

Second, thin reading: organize and summarize knowledge to form a backbone and build your own "mind map."

2. Use textbooks and learn to draw inferences.

By analogy, look for the general characteristics and laws of similar geographical things.

3. Use textbooks to summarize and master the rules of geography learning. For example:

Regional geography (continent or country): location, scope, population, topography, climate, rivers and lakes, resources, industry and agriculture, transportation and cities.

I believe that after hard work, students will love geography and learn it well.

Biology:

The study of biology class can't be based on the learning methods of mathematics and physics, and the learning methods should be somewhat similar to geography. There are not many knowledge points in a math and physics class, and a key knowledge will be trained repeatedly in class. There are many knowledge points in biology class. It is no exaggeration to say that everything the teacher says may be the test center. And the class time is tight, so it is impossible to consolidate the practice in class. Therefore, after-class exercises must be done carefully, and you should ask immediately if you don't understand.

The topic of biology is comprehensive from the beginning, and a topic will involve many knowledge points. This connection of knowledge points is emphasized or supplemented by the teacher in class. Many students read books by themselves without class, and as a result, they won't do problems after reading them. There are also students who only listen to what is in the lecture book in class, not what is not in the lecture book, because it is not important. These should be avoided.

Requirements and methods of learning biology;

1. Learning biological knowledge should focus on understanding and diligent thinking.

2. Pay attention to the process and methods of scientific research, and carefully observe and experiment.
