First of all, the basic knowledge of junior high school mathematics is the foundation of senior high school mathematics. For example, knowledge of algebra, geometry and probability in junior high school is the basis of mathematics in senior high school. If junior high school does not master these basic knowledge, it will be difficult for senior high school to understand and master more complicated mathematics knowledge.
Secondly, the learning habits and methods of junior high school mathematics will also affect the learning of senior high school mathematics. For example, the learning method in junior high school is mainly memory and understanding, while the learning method in senior high school pays more attention to logical reasoning and proof. If you don't develop good study habits and methods in junior high school, you will find it difficult in senior high school.
Moreover, the achievement of junior high school mathematics will also affect students' interest and confidence in mathematics. If junior high school students don't get good grades in mathematics, then students may have fear and aversion to mathematics, which is very unfavorable for senior high school mathematics learning.
Finally, the learning attitude of junior high school mathematics will also affect the learning of senior high school mathematics. If the attitude of junior high school to mathematics learning is not correct, it is difficult for senior high school to change this attitude, which is also very unfavorable to senior high school mathematics learning.
Generally speaking, junior high school students' poor mathematics learning has a great influence on senior high school students' mathematics learning, which is mainly reflected in basic knowledge, learning methods, learning attitude and interest confidence. Therefore, junior high school should study mathematics well, lay a good foundation and prepare for senior high school mathematics learning.
