Nowadays, obtaining education becomes an important part in children'sgrowth. Since almost every one has the opportunity to learn and teach, it becomes a controversial topic debated by peopel that what is the best teaching method? Some people believe that the best way is praising positive actions while ignoring the nagative ones. From my perspective, praising the positive actions is necessay, whereas ignoring the negative may result in unfavorable consequences. The factors which support my position are as follow. 
First of all, the reasons why people who teach other ones should praise positive actions are quite obvious. Take family and school education foe example, one of the common goals of the two types of education is shaping sane character for children or students. The children will spend one of the most important stages in family or kindergarten environment, during that period of time, kids will learn how to behave and develop their living habits. If a child washed the dishes some day, and was praised by his/her parents, the kid will acquire a sense of achievement, and is very likely to do more housework after that. This kind of praise is vital in developing children's skills for their future living. For another thing, if a student was praised for asking teacher questions about the content of the class, he/she will probably spend more time on independent thinking. In that sense, favorable outcomes will be brought about if the positive actions is praised. 
While praising serve as catalyst for encouraging children or students to do more positive actions, ignoring the negative ones have the potential to precipitate unfavorable consequences. For instance, the schools serve as small version of society, students learn how to treat other people while acquiring academic knowledge. Some of the students may become bullies because they physically grow faster than other students. If the teachers regard those negative actions as negligible ones, those students probably will continue playing tricks on others. When this kind of behavior corrupted, we will not be able to rule out the possibility that those bullies will become criminals in the future. As for the bussiness education, if the employees late for work and the boss or the manager just ignored this kind of behavior, the employees will not realize the harm of being late, and probably will continue whis behavior, thus undermine the working efficiency of the entire company in the future. Since ignoring the negative actions is capable of resulting in negative consequences, the people who peovide education should avoid ignoring them.
Admittedly praising the positive and punish the negative actions probably sometimes be counterpruductive, as praising helping others will encourage people to be more helpful, but unqualified praising may result the person in unintentionally doing harmful things to some people while helping others. And reprimanding negative actions may cause stress which prevent people for further learning. However the best way of teaching has to be temperate, educators should providently qualify the magnitude of both praising and punishing, in that way, the goal of teaching could be attained.
In conclusion, praising positiveactions has its merits, while ignoring negative has the potential to cause unfavorable consequences, in my opinion, the best way to teach should be moderately praising positive actions and rationally punishing the negative ones.
