Writing critically about theory or models

Critical reading about a theory or model

A theory is a system of ideas that tries to explain something. It's usually based on general principles independent of the phenomenon (thing) being explained. Theory also refers to a body of ideas or a set of principles on which the practice of an activity is based such as a theory of education, or a theory of marketing.

A model is a graphical, mathematical (symbolic), physical, or verbal representation or simplified version of a concept, phenomenon, relationship, structure, system, or an aspect of the real world. It's used to help understand complex real-world phenomena.

When reading about a theory or a model, find out:

  1. What are the origins of the theory/ model?
    • What issue does it seek to explain?
    • Who developed the theory/model?
    • What are its origins? Did it develop out of another model or theory?
    • How it has changed/evolved over time?
    • What are the principles on which it is based?
  2. What are the strengths of this theory or model for understanding the topic?
    • What new explanations/insights does it offer?
    • What contribution does it make to understanding of issue?
  3. What are key criticisms of theory or model?
    • What are its limitations and/or gaps?
  4. What other theory or model may be important in understanding this issue? Is this theory or model more, less or equally important in improving understanding of issue?
  5. So what?
    • In what way is this theory or model relevant to my assignment?
    • What are the implications of this theory or model for practice?
    • How can it be applied usefully to enhance practice?
