Assertion (A) : The teaching machine is essentially a technology aid which can provide easily the continuous reinforcement for the modification of desirable behaviour. Reason (R) : Behaviour can be shaped by using continuous reinforcement which can be provided by human teacher.
(A) is correct but (R) is not correct
Skinner's teaching machine was designed precisely because a single human teacher cannot realistically give every learner immediate, continuous reinforcement in a classroom; the machine automates this feedback instead. Reason (R), which credits the human teacher with easily providing this continuous reinforcement, does not capture the actual rationale for the teaching machine, so (A) is correct while (R) is treated as not correct.
