From the direction of learning transfer, learning transfer can be divided into forward transfer and reverse transfer.

Positive transfer refers to the influence of previous learning on subsequent learning. The so-called "analogy" and "analogy" are examples of forward migration.

If we learn the concept of "balance" in physics, it will have an impact on the future research of chemical balance, ecological balance and economic balance. Another example is that the study of general psychology has an influence on the study of developmental psychology and educational psychology, which is forward migration.
