The truth is simple. Children who do not develop cooperative social skills are not good citizens. Children who do not have basic math skills can't perform as adults. Children who do not communicate effectively lose. When approached as separate disciplines, these needs require all of the teacher's time and resources.
New knowledge is exciting to the children.
Teaching the scientific process through hands-on science is essentially teaching the children how to learn more effectively. When done in cooperative settings, the children also learn effective communication by sharing information with their peers. The teaching force will have access to programs for the continued improvement of their professional skills. American students will be first among the world's children in mathematics and science achievement. Our adults will be literate, and possess the knowledge and skills necessary to compete in a global economy and exercise the rights and responsibilities of citizenship.
