Of course children benefit from positive feedback. But praise and rewards are not the only methods of reinforcement. More emphasisshould be place on appreciation--reinforcement related explicitly and directly to the content of the child's interest and efforts.

In both cooperative learning and project work, the teacher encourages children to talk to one another. This helps them pay attention to each other's efforts and ideas. Children take to these kinds of exchanges very readily, but the teacher really needs to encourage this interaction.

Curriculum should help children make deeper and fuller understanding of their own experience

When a teacher tries to teach something to the entire class at the same time, chances are, one-third of the kids already know it; one-third will get it; and the remaining third won’t. So two-thirds of the children are wasting their time.

Children involved in project work are encouraged to serve the group needs and share responsibility for what's accomplished.

As you consider whether to move a child into formal academic training, remember that we want our children to do more than just learn how to read and write; we want them to learn in such a way that they become lifelong readers and writers. If we push our children to start learning these skills too far ahead of their own spontaneous interest and their capacity, we may sacrifice the long-range goal of having them enjoy such pursuits.

When children are truly involved in the scientific process they gain understanding, knowledge, and life skills. They deepen their awareness of what's going on around them and how others contribute to their well-being.
