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.

Science is a particular way of thinking about things.

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.

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.

Young children are unlikely to have their self-esteem strengthened from excessive praise or flattery. On the contrary, it may raise some doubts in children; many children can see through flattery and may even dismiss an adult who heaps on praise as a poor source of support-one who is not very believable.

Each of us must come to care about everyone else's children. We must recognize that the welfare of our children and grandchildren is intimately linked to the welfare of all other people's children. After all, when one of our children needs lifesaving surgery, someone else's child will perform it. If one of our children is threatened or harmed by violence, someone else's child will be responsible for the violent act. The good life for our own children can be secured only if a good life is also secured for all other people's children.

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