References: Time sharing made feasible the economic use of remote distributed terminals and opened up the possibilities of interactive computer use in schools. We had recently implemented TELCOMP, one of the new breed of high-level interactive programming languages. TELCOMP was a dialect of JOSS, the first "conversational" (i.e., interpretive) language, developed in 1962-63 by Cliff Shaw of the Rand Corporation; its syntax was similar to that of BASIC, which had not yet appeared. Like BASIC, TELCOMP was a FORTRAN-derived language originally designed for numerical computational applications. Shortly after TELCOMP was created, we decided to introduce it to children as a tool for teaching mathematics and in 1965-66, under U.S. Office of Education support, explored its use as an auxiliary resource in eight elementary and secondary schools served by the BBN time-sharing system. Students were introduced to TELCOMP and then worked on standard arithmetic, algebra, and trigonometry problems by writing TELCOMP programs. The project strongly confirmed our expectation that the use of interactive computation with a high-level interpretive language would be highly motivating to students. Extract: LOGO based on LISP Incredibly, the best model for the new language (which was to be as simple as possible) turned out to be LISP, the lingua franca of artificial intelligence, often regarded (by non-LISP users) as one of the most difficult and formidable of languages. Of course, the syntax of Logo is much more familiar and accessible than that of LISP Essentially, though, Logo is LISP and is thus both an easy and a powerful language. The power is not evident in most existing microcomputer implementations, mainly because of their small memory and restricted performance.
