Science Education for a New Age The very great advances in science just before and after the midpoint of the twentieth century have caused education in the United States to realize that science teaching in the future must differ from :science teaching in the past.__ (1) The welfare, stability, and security of our nation are closely related to the discoveries of science and the application of these discoveries. ; Governors, lawyers and business leaders have to deal with scientists and every educated person has his views influenced by science.__ (2) 'I never did understand science.'Even those students who arrive at college with plans to become scientists usually bring a mistaken picture of science; some have a collection of unorganized facts about science; and some regard the study of science as a game that involves getting the right answer. If it were only necessary to decide whether to teach elementary sciehce to everyone on a mass basis or to find the gifted few and take them as far as they can go, our task would be fairly simple.__ (3) Because we depend so heavily upon science and technology for our existence and progress, we must produce specialists in many fields.__ (4) Science teaching must deal withthe knowledge and methods of science; both are necessary.From science courses students should acquire a useful command of science concepts and principles.Science is more than a collection of unrelated facts; to be meaningful and valuable, they must be arranged to show generalized concepts. (5) He must see that knowledge is subject to growth and change and that it is likely to shift in meaning and status with time. Young people need to understand how our society depends upon scientific and technological advancement and to realize that science is a basic part of modern living.The'scientific process and the knowledge produced cannot be considered to be ends in themselves,except for the classical scientist.A student should understand the relation of basic research to applied research, and the connection between technological developments and human affairs.
