Hal Abelson is a computer scientist whose work uses computer programming as a way to express and investigate ideas. With Gerald Jay Sussman, he developed the course behind Structure and Interpretation of Computer Programs by Harold Abelson and others. Its use of Scheme connects concrete programs with programming abstraction, recursion and the organization of computations.[ref]
His work on Logo and computational geometry also brought mathematical exploration into programming education. Rather than treating a program only as a sequence of commands, this approach lets a learner examine how a compact procedure generates an entire family of behaviours.[ref]
