1, teaching methods and curriculum: If science education pays too much attention to the teaching of theoretical knowledge and ignores the cultivation of practical application and innovative thinking, then students will feel abstract and difficult to understand what they have learned because of the lack of opportunities for actual participation and experience, which will lead to forgetting.
2. Lack of motivation: When students don't have enough internal motivation to study science, they won't put enough energy into understanding and memorizing this knowledge. This is due to a lack of understanding of the importance of science, or that science has nothing to do with your future career and personal interests.
3. Teachers' quality and educational resources: If teachers' teaching ability and resources are limited, they can't effectively stimulate students' interest and curiosity, and can't provide necessary support to help students overcome their learning difficulties, which will lead to the decline of students' memory of science education.
