Teaching problem solving and structured programming in FORTRAN

This paper describes an approach to teaching problem solving in an introductory programming course using the FORTRAN language. The course is oriented around a set of problems which are used to illustrate a problem solving methodology. Three pedagogic aids (data table, flow diagram, and program system chart) and two control structure extensions to the FORTRAN language are used in order to provide a more convenient framework in which students can practice good problem solving and programming techniques. The control structure extensions facilitate structured programming in FORTRAN. The use of the control structures and the pedagogic aids is illustrated in the solution of a simple statistics problem: the benefits derived from using these aids are also discussed.
