Writing Article Critiques
A written critique includes a minimum of four basic elements:

Identification of the material read (or reviewed).
An abstract of the major ideas.
An analysis of the content.
Implications for the particular course, study or field      of interest.

The first “things” to look for in an identified reading are the major ideas and contentions of the author. Try to determine the author’s justification for the contentions. Review the supporting data presented. Examine the logic supporting the author’s conclusions. Seek out similarities and differences between what is being propounded by the author and those held by other writers in the field.
In summary, what is the “gist” of contents of the review? Can it be stated in a few paragraphs? What does it mean? What are the implications?
