Needs vary from person to person, according to local conditions. In the process of education, praise and criticism are often used. Praise is to praise the strengths and advantages of young children. Praise is by no means boasting, exaggerating and following one's inclinations, but seeking truth from facts and treating each other sincerely, thus further stimulating and mobilizing enthusiasm. Criticism is a process of analyzing and denying the shortcomings and mistakes of young children. Criticism is by no means sarcasm, catching braids, swearing or revenge, but in a kind and fair way, it helps children understand and correct their mistakes, accept lessons and enhance their vitality and activity. In the process of psychological education, the correct use of the above forms of praise and criticism can make children improve their understanding, enhance their good motivation for activities, stimulate positive mental emotions, promote the formation and development of their abilities, and enhance their self-motivation and sense of responsibility. Only by combining praise and criticism skillfully, giving priority to praise, supplemented by appropriate criticism, can we achieve the real purpose of education.
