Rewards are much more powerful than punishments in discipline and learning. Focus on the positive and ignore the negative if possible. Help students find their own rewards to learning a second language. Praise and encourage students who do well. Have high expectations for all children.
Expectations influence achievement.
Higher expectation leads to higher achievement. If students are told they are not smart they will be discouraged. Do not physically or verbally harm children. Correct their bad qualities using scientific methods that do not pervert their characters. Motivation to learn based mainly on avoiding punishments is ineffective.
