One method for teaching students how to critique or analyze artwork effectively is to model a critiquing behavior and ask students to emulate it. Steps to follow are:
1. Model the behavior.
2. Students practice the behavior.
3. Feedback and discussion of the experience.
Ex. Choose a work of art and analyze it out loud, explaining during each step why each step is important. Then have students pair up and choose an artwork to analyze, using the steps and procedures you had modeled for them. Prepare a handout that outlines the various steps you expect them to make while analyzing/critiquing work in order to make this easier. Discuss with them afterwards the pros and cons of analyzing artwork in this way.
