The constructivist perspective on learning could very well be suited for vocational teaching.

Learners are the makers of meaning and knowledge

As a teaching-learning method, the constructivist stance might be slower. The goal is that the vocational student builds a understanding alongside the acquisition of facts, techniques and procedures. The pre-existing or existing knowledge that the student shall build upon is called a schema.

From the above, It can be deduced that learning happens one step at a time, like stories being added to a building one after the other - never should one story be skipped in this view.
