Secondary school teachers incorporating the use of a computer in algebra, trigonometry, advanced mathematics, chemistry, or physics classes are the individuals for whom this book is intended. The content included in it is designed to aid the learning of programing techniques and basic scientific or mathematical principles, and to offer some solutions to illustrative problems. Eight units are devoted to a step-by-step explanation of the FORTRAN IV language and programing, with material presented in a manner which assists the teacher in developing lectures and other forms of instruction which facilitate student imitation and encourage early operation of his initial attempt at programing. Following this introduction to FORTRAN and to programing is a problem supplement with five sections, one each devoted to algebra, trigonometry, advanced math, chemistry, and physics. A short bibliography is also included. (Author/LB)
