The learner, the society and the subject matter are three important focal points which inform any curriculum. Is the relative emphasis of any of these of benefit to the UK educational system?
Yes, but the answer is subjective depending on the perspective of the stakeholder and their stake. I can't speak directly about the U.K. context, but I came across a piece that offered you might use the foci to examine current curricular trends.
In the U.S., according to Connelly and Clandinin (1988) there was a focus on the learner to subject matter with an emphasis on technical rationalism during the 1950s, back to the learner and now to subject matter and society (in my opinion, schooling as job training and increasing the GDP). International competition (society) spurned by the PISA test has accounted for a change in many systems throughout the world.
As a start, the above authors recommend choosing any controversy on curriculum and label which focal points are emphasized either verbally or in print.
I just reread Tyler's seminal work. You could also consider the answer from the point of view of what the reconstructionist (society) essentialists (subject) and progressives (students) are up to in the U.K. these days.
the three factors must be treated in their interdependence
The three factors must be treated in their interdependence: the structure and function of the curriculm I harmony with the nature and needs of the learner and the ideals and practices of the democratic society. See tanner & tanner CURRICULUM DEVELOPMENT, 4rh ed.
