- A balanced development occurs because of the combined role of heredity and environment.
- A child may have good heredity background, but if the environment in which he or she is brought up is not good, he or she may not develop adequately.
- On the contrary even if the heredity is not good, favourable environmental factors can help in a child’s development.
- Awareness of a child’s heredity and environment is important for a teacher. This awareness will help the teacher understand the reasons behind a child’s behaviour and facilitate his or her development.
- It also gives a complete perspective of the child’s tendencies, desires, problems and aspirations and helps the teacher to interact with the students as required.
