What is a Theory?

What is a Theory?

Popper: All theories are trials they are

tentative hypothesis tried out to see

whether they work.

What is a Theory?

Popper: All experimental corroboration is

simply the results of tests undertaken in a

critical spirit in an attempt to find out where

our theories err.

What is a Theory?

Theory refers to an organized set of

propositions that are syntactically and

semantically integrated and serve as a

means of predicting and explaining

observable phenomena.

What is a Model?

The Concretization of a Theory.

or

Theories with a more narrowly defined

scope of explanation.

Every model is based upon a theory.

Difference between a model and a theory

A theory is explanatory as well as descriptive, while a model is descriptive.

Theories and Models

The purpose of theories?

  • To Guide practice (Prescriptive)
  • To explain phenomena (Explanatory)
  • To predict outcome (Predictive)
  • To Enlighten understanding (descriptive)

Theories and Models

Prescriptive: To Guide practice

A prescriptive theory gives directions or

rules as to how something should work or

be carried out.

Explanatory : To explain phenomena

Explanatory theories seek to explain the

behavior of our world; they tend to provide

a more conceptual model of the world.

Predictive: To predict outcome

Predictive theories seek to predict

outcomes based on the changing values of

component variables.

Descriptive: To Enlighten understanding

  • Methodology that yields a description of the behavior, event, or object of study without necessarily analyzing or providing its cause.
  • Describes phenomena as they are hypothesized to exist

Descriptive Theory

What is it?

A descriptive theory seeks to support the

process of thought, by providing consistent

and appropriate terminology.

Probabilistic Theory

What is it?

Probabilistic Theory

It may probably take place – It is not

certain.

Why?
