Dick and Carey first created their Systems Approach Model for Designing Instruction (commonly referred to as the Dick and Carey Model) in 1978. They created the model after noting that the default way to create a new learning project was by modeling an existing project, but they felt that was a poor approach since every learning project is designed distinctly for its intended purpose – a more generalized model needed to be created. They noted that no systems-based model existed specifically for designing instruction, so they created one based on research as well as their practical experience in the field. They liken it to a recipe – if you’re a novice, it’s a good idea to follow each part – in order – but as you become more familiar with it, you can change it to meet your needs.
Here is their model from The Systematic Design of Instruction:
