Excerpt from Teachers' Manual to Accompany New Civic BiologyIT was Huxley who compared the life of an organism to a whirlpool, the particles of which were constantly changing. A similar analogy may be made with reference to the contents of a course in Civic Biology of the present day. Not only is the content of the course continually changing, but also the methods by which the contents are taught are in a state of flux. The alert teacher is always ready to add or to subtract from the methodology used and the subject matter presented.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
