Instructional Science: Notes from Reigeluth, Bunderson & Merrill
RBM writes in the 1978 article about the design science of instruction.
They use their own terminology for ID/IDev:
1. a prescriptive design science with 3 phases: design (methods of instruction), production (methods of organization & media production), validation (methods of measurement)
2. 3 approaches for each phase: artistic, empirical and analytic
3. design science of instruction is foundation of design
4. 3 types of professionals in instructional science: scientists, technologists, technicians
5. theory construction procedures:
a) development of a taxonomy of instructional variables;
b) formulation of a few basic postulates that relate those variables to each other;
c) empirical validation/repudiation of postulates through experimental testing of hypotheses;
d) testing of variables in realistically complex models or systems of instruction
