Arrange the following in sequence as they are introduced in increasing order of age of the students:

By increasing age of the students the ideas appear as team teaching, taxonomy of educational objectives, personalised system of instruction and the interaction model of teaching.

Team teaching, several teachers sharing a class, is used from the earlier school stage.

The taxonomy of educational objectives then guides framing and grading learning aims.

The personalised system of instruction, a self-paced mastery approach, suits older college learners.

The interaction model of teaching, focused on classroom communication analysis, is placed last in this ordering.

Fred Keller devised the personalised system of instruction as a self-paced college method.
