On doing
some research on critical thinking I came across this framework that shows the process
of critical thinking from the first engagement with information to the
development of arguments and conclusions that form the basis of your critical
writing. It clearly has its roots in Bloom’s Taxonomy (Bloom et al, 1956) but has been developed to
include extra steps that are need for critical thinking.
Figure 1:
The Critical Thinking Stairway (Williams, 2014)

Figure 2:
Bloom’s Taxonomy Bloom et al (1956)

I have used
the Stairway with students who are working on case studies and research
projects both to show them the steps they need to take and also as a monitor of
progress by revisiting the stairway during the process.
I hope you find this useful and would welcome feedback and comments
especially if you have found another way of using the stairway.
