“…Palumbo and Reed (1987/88) have used the term "intensity of treatment" to describe the treatment provided in problem-solving/programming language research. According to Palumbo and Reed (1990), intensity of treatment is a function of three main components: (a) the amount of actual time spent working on the computer, (b) the rigor of the information presented in the compu:er learning atmosph®, and (c) the proximity of instructional sessions to each other. (p. 11) There are several languages available for teaching programming to students at the high school or college level, including LOGO, BASIC, Pascal, FOR-TRAN, COBOL, C, PROLOG, LISP, and so on.…”
