    Parents are important elements in the children’s educational progress. They are capable of being good resources not just for children, but also for schools and teachers.
    Parents can help children realize the value of education through their love and support, and most importantly, their encouragement plays an important role in educational success. So parents can be more involved in children’s classroom activities. For example, parents can help out with teaching arts and crafts(工艺美术)to preschoolers and children in grades 1-3. Asking parents to show the children their own talents and impart(传授)the knowledge on the subject they love is a good way to involve the parents in their children’s education. And as a teacher, having someone on call to help you with the cutting and gluing(粘)during a craft class will ensure a less daunting(使人畏缩的)job.
    Having parent volunteers around when organizing activities for children is definitely an advantage. Organizing field trips, outings, community services, camps, etc., can be a daunting task when you are the only member responsible for catering to the needs of a large group of children. At such times, asking parent volunteers to help out with the basic requirements makes perfect sense. You can even ask them to stay together with students on camping and field trips or help with community services. And activities which allow them to mix freely with the children will help them understand the needs of the children better.
