Tyler (1949) has provided a useful definition for designers working at the micro level:
‘A learning experience refers to the interaction between the learner and the external conditions in the environment to which he can react. Learning takes place through the active behaviour of the student; it is what he does that he learns not what the teacher does.’
This definition has many implications for the design of instruction. We will come back to it again, directly or indirectly, more than once.
