I am a teacher at a post secondary automotive training school. I teach a program where the usage of critical thinking skills will help a student advance more rapidly than a student not applying them - which is true for just about anything. What I struggle with is most student's inability to deal in the "grey area" - that is to say that if they are facing a challenge that isn't a simple black or white task/activity, some will either shut down, stating that "this is stupid" rather than thinking and working through the challenge to come up with a positive outcome. Some students demonstrate proficiency in this skill, but not enough to be able to impact other group members in a way to encourage them to try what they witness from their peer. Any input would be helpful. Thanks in advance.
