However important we may regard school life to be, there is always the fact that children spend more time
at home than in the classroom. Therefore, the teacher should realize that parents have a great influence on their
children. Parents can become strong allies (助手) of the school or they can get in the way of the school
education.
Experts have realized the need to keep parents informed of the newer methods used in schools. Many
headmasters have conducted workshops explaining such matters as the reading readiness, program writing
and mathematics to parents.
Moreover, the classroom teacher, with the permission of the supervisors(管理者), can also play an
important part in giving more knowledge to reporting pupils progress, teachers can help parents a lot in
educating their children and parents can give much help to teachers.
Suppose that a father has been drilling Junior arithmetic lessons night after night. In a friendly talk between
the teacher and the father, the teacher can help the parent to make Junior interested in it. He might be persuaded
to let Junior join in discussing the family budget, buying the food, using a ruler or measuring cup at home,
setting the clock, calculating the distance of a trip and engaging in scores of other activities that have a
mathematical basis.
If the father follows the advice, it is reasonable to say that he will soon realize that his son is making
satisfactory progress in mathematics, and at the same time, enjoying the work.
Too often, however, teachers' talks with parents are devoted to small accounts of children's misdemeanors(不良行为). They talk about the laziness and poor work habits of the children.
What is needed is a more creative way in which the teacher, as an adviser, plants ideas in parents' minds to
make sure that the child spends the many hours out of the classroom learning something useful.
In this way the school and the home join forces in educating children.
