At first the author shows the problem on American scientific understanding with three questions.
Then he show the concern of experts:one is that only about a third of adults show a good understanding of the scientific process,another is that United states can’t provides a sufficient supply of qualified workers for careers in science and technology.
At last,he shows the way to solve the problem:
1.Depend on teaching.
2.Teach critical thinking.
3.Provide inducements like more mentoring,better teaching assignments and chances to take class and seminars.
4.Let the scientifically literate citizens take more control of science-related government by bombarding legislators with e-mails.
