biology

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

The basic concepts, principles and laws of biology are summarized and generalized on the basis of a lot of research, which are closely related to the contents of each chapter in the textbook. Therefore, in the process of learning this knowledge, we should not be satisfied with simple memory, but should thoroughly understand and master it.

2. Pay attention to understanding the scientific research process and learning scientific research methods?

The content of biological science includes not only a lot of scientific knowledge, but also the process and method of scientific research. Therefore, we should not only pay attention to the study of biological knowledge, but also pay attention to the process of students' biological science research, so as to understand the research methods of biological science.

Pay attention to observation and experiment. Biology is an experimental science?

Without observation and experiment, biology could not have made such brilliant achievements. Similarly, it is impossible to learn biology well without paying attention to observation and experiment. In daily life, we should also pay attention to observing life phenomena and cultivate our own observation ability.

We should attach importance to integrating theory with practice and apply what we have learned?

Biology is a science closely related to production and life. When learning biological knowledge, we should pay attention to understanding the relationship between science and technology and society (STS), understand the social value of the learned knowledge, and use the learned biological knowledge to explain some phenomena and solve some problems.
