First of all, it is necessary to understand three points of view:

1, learning biology to have interest. Interest is the driving force of learning, is the first teacher of learning, with interest, will be actively and happily engaged, will not feel that learning is a burden.

2, to pro-teacher. As the old saying goes: pro-teacher faith, if a student likes the teacher, then the teacher's performance in this subject he certainly will not be poor.

3, to start from the first year of high school. The first year of high school is the starting point, is the foundation. Lay a good foundation, step by step, learning is not difficult, like climbing a tower, looks very high, some afraid, until along the ladder step by step up, in fact, is not difficult.

High school biology in the end how to learn:

1, grasp the law

Law is the nature of things inherent in the inevitable connection. Biology has its own laws, such as the structure and function of the appropriate, local and overall unity, biological and environmental coordination, as well as simple → complex, low → high, aquatic → terrestrial evolution. Mastery of these laws will help the understanding and application of biological knowledge, such as mitochondria learning should be grasping the structure and function of the law of compatibility: there is a double membrane, the inner membrane folded inward to form a ridge, expanding the membrane area, which is conducive to aerobic respiration enzymes in its regular arrangement; thus, the mitochondria is the main place of aerobic respiration. This is easier to understand and remember its structure and function.

2, observation and comparison

Observation is a purposeful and planned perception, not only to obtain new knowledge, but also to verify the known. Biology is an experimental science, observation is an important part of obtaining biological knowledge. Such as observing the morphological structure of organisms, habits, growth and development, etc., effectively play the role of observation in biology learning. And the principles and laws of our biology are based on observation and experimentation.?

Comparison is an important way to understand things, there are comparisons to identify, biology can be compared to a lot of things, such as animal cells and plant cells, photosynthesis and respiration, hibernation and hibernation and so on. Comparison of attention to a comprehensive understanding of the comparative object, and then determine the comparative project, and to do concise, such as photosynthesis and respiration of these two types of physiological processes, can be from the place, conditions, process, results, significance, etc. for a comprehensive understanding. Through comparison is conducive to understanding the essence of photosynthesis, respiration. Secondary school biology concepts, easy to mix and difficult to remember, comparison is one of the effective methods.

3, synthesis and generalization

Teachers, especially new lectures, is generally divided into chunks, but there is an intrinsic and essential link between the knowledge of each block, the biological knowledge of all grades is coherent, is a whole. Learning should be scattered knowledge gathered, summarized and organized into a systematic knowledge, so that easy to understand and remember.

Synthesizing and summarizing should do "three grasp". A grasp of the order, two grasp the connection, three grasp the characteristics. Grasp the order is to be in accordance with their own logical relationship between the knowledge points will be linked, such as the material basis of high school genetic knowledge can be linked by the central law of the main line. Grasp the connection, such as nerve cells and the brain, spinal cord, the point of contact is that the nerve cells are divided into two parts of the cell body, protrusion, cell body composition: brain, gray matter of the spinal cord and so on. Grasp the characteristics, that is, to grasp the focus of the mainstream. Comprehensive generalization is not a browbeat, not a hodgepodge, should be simplified or even cancel the secondary things.

4, flexible use

This is the key to learning to learn live biology, the purpose of understanding all lies in the application. Flexible use of knowledge in order to remember, learning is really useful. Use of knowledge to solve theoretical problems or solve practical problems in production and life, especially the latter is the weak link in secondary school students, must attach great importance. Such as high school learned mitosis, meiosis, to clarify the two cell division process of chromosome morphology, the number of changes in behavior, the use of this knowledge can be used to identify mitosis and meiosis diagram. Learned ecology and other knowledge at home to try to build ecological neighborhoods, the development of garden economy and so on. As long as you have the heart, biology is everywhere, everywhere, will be able to learn, learn to live.

5, but also need to master a good memory

Memory is the basis of learning, is the storehouse of knowledge, is the partner of thinking, is the premise of creation, so learning based on different knowledge of the characteristics of the appropriate memory methods, can effectively improve the efficiency and quality of learning.

Memorization methods are many, the following are only a few of the most common in biological learning.

a Simplified memory method that is, by analyzing the textbook, find out the main points, the knowledge will be simplified into a few regular words to help remember. For example, the molecular structure of DNA can be simplified to "five, four, three, two, one", that is, five basic elements, four basic units, each unit has three basic substances, many units form two chains of deoxyribonucleotides, becoming a regular double helix structure.

b Associative memory method That is, according to the content of the textbook, clever use of association to help remember. For example, remember trace elements: iron, manganese, boron, zinc, molybdenum and copper, these six elements, you can use the harmonic memory of iron slammed into a new barrel, so that remember, and not easy to forget.

c Comparison of memory in biology learning, there are a lot of similar terms are easy to confuse, difficult to memorize. For such content, you can use the contrast method to memorize. The contrast method is to list the relevant terms individually, and then compare them in terms of scope, connotation, extension, and even text, so as to find similarities and differences, and to identify the differences. The contrast is obvious and easy to memorize. For example, assimilation and heterogeneity, aerobic respiration and anaerobic respiration, hormone regulation and neural regulation, material circulation and energy flow and so on.

6, and finally to form a good learning routine. The establishment of a good study routine is an important guarantee of good knowledge of biology, said study routine, refers to our learning process must pay attention to several steps, including pre-study, listen to lectures, review and homework, summarize the steps.
