B. F. Skinner’s techniques for programmed instruction involved all of the following EXCEPT a. incorrect responses are counted and used as the basis of a final score on the program. b. the pupil receives immediate feedback as to whether a response is right or wrong. c. a subject is broken down into a series of stepwise components that are presented sequentially. d. the programs were administered mechanically in devices called teaching machines.

B.F. Skinner, a behaviorist in 1950s presented a programmed instruction, that is defined as a system that makes the learner uses specially prepared books or equipment to learn without a teacher.

The purpose, is to enable teachers to be free from burdensome drills and repetitive problem-solving inherent in teaching basic academic subjects like spelling, arithmetic, and reading. Skinner's ideas is centred on the principle of operant conditioning, which theorized that learning takes place when a reinforcing stimulus is presented to reward a correct response.

In his belief, Skinner felt that program instruction learning could, be better compared to traditional teacher-based instruction because children were rewarded immediately and individually for correct answers, instead of teachers correcting them at later time.

Hence, B.F. Skinner program instruction involved all the afore-mentioned except incorrect responses are counted and used as the basis of a final score on the program.
