Biology learning methods in the second year of junior high school are recommended, and how to learn

My child was also a little anxious because of his poor grades before the exam, and then the child went to Beijing New Oriental Primary and Secondary School 1-to-1, and this problem was gradually solved. The teacher of New Oriental said that the problem of the child was that the practice was not enough, and then formulated a detailed learning plan.

Examine the mistakes you have made, find the loopholes in your knowledge, the deviations in your way of thinking, the omissions in the problem-solving specifications, and the points where the errors are concentrated as the focus of training, and purposefully select some materials for training, so as not to let the same mistakes recur in the high school entrance examination.

Biology is simply the liberal arts in science, and biology in junior high school is even more so, just memorize one word, but no matter when you can't break away from the textbook memorization, after memorizing the key content drawn by the teacher in class, you can better grasp the knowledge points in the workbook.

There is no special method for biology, you just need to listen carefully in class, write down what should be memorized, and complete the homework left by the teacher carefully, and you can generally learn very well.

Answer: Biology in the second year of junior high school is relatively simple, as long as you listen carefully in class, master the key knowledge given by the teacher, complete the homework left by the teacher, and memorize the key points drawn by the teacher. Then you will definitely get excellent grades.

Therefore, listen carefully to the class, grasp the key points, complete the homework on time and as required, and memorize the content that should be memorized.

Let's take a look at the learning methods of biology in the second year of junior high school:

1. Be able to listen to lectures

When listening to lectures, we should not only maintain strong energy, but also achieve eyes, ears, brains, and hands, and mobilize multiple senses to participate in learning.

When teachers give lectures, especially new courses, they are generally divided into blocks, but there is an intrinsic connection between each block and each knowledge point, and the biological knowledge of each grade is coherent and a whole.

When learning, it is necessary to gather scattered knowledge and summarize it into systematic knowledge, so that it is easy to understand and remember.

The learning of biological knowledge has the characteristics of this discipline, so it is necessary to have the following three perspectives when listening to lectures:

1) The structure and function of the organism are unified;

2) adaptation of organisms to the environment;

3) Biological evolution and development.

In class, it is important to pay attention to how the teacher uses these basic viewpoints to analyze the phenomena and nature of life.

For example, in the chapter on the digestive system, pay attention to how the teacher analyzes the structure of each section of the digestive tract, especially the characteristics of the structure of the small intestine that are compatible with the digestion and absorption functions of the small intestine.

2. Be good at reading

You can carefully prepare a reading outline in advance for the content to be learned, and this outline can be listed according to the exercises after class, and then read the relevant texts purposefully, so as to grasp the key points and make yourself gain from reading.

When learning about water absorption, consider the circumstances under which plant roots absorb water from the soil. When too much fertilizer is applied at one time, why does "seedling burning" occur"。

Reading the content with questions will give you a clear grasp of the principles of water absorption and loss in plant cells and the structure of mature plant cells.

Double fertilization process in angiosperms. By grasping the map, we can first understand the germination of pollen, the formation of pollen tubes and the structure of ovules, and then understand the action map of double fertilization, and then understand the role of double fertilization.

Conceptual Principles Key Reading] The conceptual principles in biology are rigorous and scientific, and must be tempered through thinking activities in order to grasp their essential connotations. Such as:

Angiosperms are generally composed of six organs: roots, stems, leaves, flowers, fruits, and seeds, of which "general" means that the vast majority of angiosperms have these six organs, and a few do not have them completely.

Third, grasp the law

A law is a necessary connection between the intrinsic nature of things themselves. Organisms have their own laws, such as the adaptation of structure and function, and the integration of parts and wholes.

1. The harmony between living things and the environment, as well as the evolution of simple and complex, low-level and high-level, aquatic and terrestrial organisms, etc., all have certain laws.

Listen carefully in class.

After class, read the notes and do the exercises.

Think more about the extracurricular part of the teaching staff.

Write down the incomprehensible and ask the teacher into a cycle.

Listen carefully in class and do nothing after class.
