     However important school life may be, we can't ignore the fact that children spend more time at home

than in the classroom.Therefore the great influence of parents can't be ignored or discounted by the teacher.  They can become strong supports of the school or they can consciously or unconsciously prevent the

school from accomplishing its aims.

     Administrators have been aware of the need to keep_parents_apprised_of the newer methods used in

schools.Many principals have conducted workshops explaining such matters as the reading readiness

program and developmental math.

     Moreover, the classroom teacher can also play an important role in explaining to parents what they

should do.The informal tea and many interviews carried on during the year, as well as new ways of

reporting pupils' progress, can significantly aid the interchange of ideas between school and home.

     Suppose that a father has been drilling Junior in arithmetic processes night after night. In a friendly

intervie  w, the teacher can help the parent change his method.He might be persuaded to let Junior

participate in discussing the family budget, buying the food, using a measuring cup at home, setting the

clock, calculating mileage on a trip and engage in scores of other activities that have a mathematical basis.

     If the father follows the advice, it is reasonable to assume that he will soon realize his son is making

satisfactory progress in math and at the same time, enjoying the work.

     Too often, however, teachers' conferences with parents are devoted to unimportant accounts of

children' s wrongdoing, complaints about laziness and poor work habits, and suggestions for punishments

and rewards at home.

     What is needed is a more creative approach in which the teacher, as a professional advisor, plants

ideas in parents'minds for the best use of the many hours that the child spends out of the classroom.In

this way, the school and the home join forces in fostering the fullest development of youngsters'

competence.
