This instructional unit of five lessons and four appendices is designed to acquaint both teacher and student with the elementary aspects of computer programming. The first two sections contain background information in computer processes and in BASIC language for a time-sharing system for those teachers who have limited backgrounds and experiences in computer science. Lessons I and II cover giving instructions in English and in BASIC; lesson III deals with translating instructions from English into BASIC; lesson IV introduces conditional control statements through simple programs; and lesson V looks into the use of subscripts in a BASIC program. Each lesson contains suggested teacher questions and related exercises for students. Appendix A contains two programs to be put on tape and checked during lessons II and IV. Appendix B contains six handouts for use with lessons II through VI. Appendix C contains the analysis of programs to find the roots of quadratic equations and also a summary of BASIC symbols. Appendix D contains programs for sums of series, dividing a line, and changing bases. (JBW)
