Developing design documents (3D) model

The 3D model of design documentation is a framework to discuss various kinds of instructional design languages and documents.

Boot (2005:26) argues that “production-related information is typically embedded in three types of building blocks for the production process: (a) design documents as input, (b) programming structures as throughput, and (c) learning materials as output.”

3D model includes three major dimensions:
  • stratification: Functionally different instructional and technical structures
  • degree of elaboration: conceptual, specification or implementation
  • formality: formal vs. informal

Stratification

Layers of instructional design

Gibbons (2000) argues that instructional designs are layered structures. Layering is a general design principle.

  • Content layer
  • Strategy layer
  • Control layer
  • Message layer
  • Representation layer
  • Media Logic layer
  • Management layer

Each instructional design layer is the defined by:

  • A specific set of design goals or problems
  • Sets of layer-specific design structures, expressed in the terms of design languages
  • Principles for the selection, arrangement, and mapping of structures within a layer
  • Principles for the relation of structures across layers

Elaboration

Boot (2005:27) adopts Fowler's three perspectives for which different levels of detail can be specified:

  • A conceptual perspective, with more or less superficial and descriptive information;
  • a specification perspective, with more or less comprehensive and detailed information,
  • an implementation perspective with more or less technical and meticulous information

Formalization

Designers can choose to use formal design languages or not.

  • formal
  • informal
