A model is really the first step in curriculum development. A curriculum model determines the type of curriculum used; it encompasses educational philosophy, approach to teaching, and methodology. The good news is, unless you've been hired to design curriculum, you won't come across many curriculum models. However, it's good for educators to be familiar with the models used in their schools
The basic tenet of the dynamic or interactional models of curriculum development is that curriculum development is a dynamic and interactive process which can begin with any curriculum element (Print 1989, Brady 1990).
Walkers Model of Curriculum develop by Decker Walker 1971.
The proponents of this approach to curriculum development argue that the curriculum process does not follow a lineal, sequential pattern. Dynamic models have emerged from a more descriptive approach to curriculum where researchers have observed the behavior of teachers and developers as they devise curricula. Consequently the analytical and prescriptive approach, the very basis of the objectives and cyclical models, is not prominent in the dynamic models.
Platform
The three phases of Walker's model are the platform phase, the deliberation phase and the design phase. In the platform phase, platform statements made up of ideas, preferences, points of view, beliefs and values that are held by curriculum developers are recognized.
Deliberation
When the curriculum developers start discussing on the basis of the recognized platform statements, this is the second stage of deliberation, which is a complex, randomized set of interactions that eventually achieves an enormous amount of background work before the actual curriculum is designed (Print 1989 ).
Design
In this phase developers make decisions about the various process components (the curriculum elements). Decisions have been reached after extended discussion and compromise by individuals. The decisions are then recorded and these become the basis for a curriculum document or specific curriculum materials.
