Critical evaluation is to engage in a form of writing and thinking that explores your argument and others' arguments/findings/proposals and assumptions
you have to answer following:
'whose interests are served by what is being done'

'whose interests are not served by what is done'

'what are the political, cultural, social, religious and economical effects of the "events'?
A critical evaluation should engage in a dialogue with the reader, asking questions and evaluating options
or in short
the main aim is e.g. to analyse, explain, evaluate, argue, citicise, discuss opposing views.

e.g you give detail of history
its impacts,
different perspectives,
authors' views
criticisms
your own assessment
final judgement/conclusion regarding question, justified by your above discussion
