The arena of instructional design was perceived as an endeavour to develop a particular, perfect instructional theory based in systems theory that would indicate teacher attributes, cataloguing and evaluation processes, and methods to modify the design systems being tested. The intention from this standpoint was the designing of instructional programs that would help majority of the students to attain stages of performance that were previously scheduled in terms of behaviourally defined objectives. The 21st century witnesses the materialisation of a novelseries of technological tools capable of offering learners more realistic learning experiences grounded on experimentation and action. Consequently, the students require a new goal direction and objective setting. This situation demands an immediate and drastic change in the entire educational pattern. A paradigm shift is inevitable for the whole educational system. In this paper, an objective based instructional architecture of classroom interaction designs is evolved through a timeline of objective based instructional development. Besides, the general impact of the instructional theories on the new generation learners is analysed.
