1, math:
Junior high school mathematics is a subject of learning quantity, structure, change, spatial model and other concepts. It includes metrology, algebra, geometry, data analysis and probability. Mathematicians count, calculate, measure and observe the shape and motion of objects through abstract and logical reasoning.
Mathematics learning needs to master the knowledge of geometry and statistics, and mathematics problems are relatively simple and easy to make mistakes. Junior high school mathematics learning needs to study hard, master basic knowledge, improve mathematics ability and lay a solid foundation for future study and life.
2. Physics:
Junior high school physics is a part of natural science, which studies the material structure, interaction and movement law of nature. Physics is one of the five main courses in junior high school, which requires students to learn basic knowledge from primary school and lay a good foundation for physics. The learning methods of physics also need to be mastered, so as to better understand the application and practice of physics.
3. Biology:
The main courses in junior high school are Chinese, mathematics, English, physics, chemistry and biology. Among them, biology is a branch of natural science, which studies the structure, function, occurrence and development of organisms and the relationship between organisms and their surrounding environment. The core idea of biology is to explore the basic laws of biosphere.
By studying the life phenomenon in the biosphere, we can understand the development trend of the earth. Learning biology well can improve our scientific literacy and experimental ability, and also improve our scientific inquiry ability. Besides biology, other minor courses in junior high school include history, geography, ideology and morality.
4. Geography:
Junior high school geography curriculum includes two parts: physical geography and human geography. Among them, physical geography is a discipline that studies the earth and its characteristics, inhabitants and phenomena, while human geography is a discipline system that studies the interaction, spatial differences and changes of the earth's surface.
Learning geography well can improve our geographical literacy and environmental awareness. Geography is the basis of studying the earth, including earth foundation, human geography, physical geography and so on. Only by learning geography well can we make continuous progress in our study and improve our comprehensive quality.
