In this article, Dr. Brandwein discusses several different concepts of the term "general science," such as what might be called "exploratory science," "survey of science," "introductory science," etc. Next, he draws on his wide experience in the field, concluding that "most school systems in the country have planned or are planning for a general science experience in the junior high-school years—the seventh, eighth, and ninth grade." The bulk of the article is then devoted to a four-step de velopmental account of the evolution of general science teaching. These steps, as outlined and discussed, are: (1) a survey of subject matter, (2) an aid to understanding the environment, (3) an aid in solving problems of living, and (4) a core-program, including science, designed as an aid in meeting pupils' needs and interests.
