Provide "acknowledged body of knowledge" related to the concept. Emphasize the most significant aspects of the concept in an organized, organic manner.

Instruction in and modeling of Evaluative Thinking steps.

Objective: To teach the evaluative process of thinking.

Activity: Using overhead transparencies, the teacher introduces and models the steps in the evaluative thinking process, as taken from Thinking Strategies and Skills by Barry Beyer:

• Determining the trait to be evaluated.
• Identifying the criteria to be applied.
• Defining the criteria in terms of exemplars.
• Examining the data to find evidence of exemplars.
• Judging the extent to which evidence matched the criteria.
• Stating a judgment.

The students are encouraged to analyze the process as modeled by the teacher. Examples modeled by the teacher might include, "What is a good essay?" and/or "What is a good pet?"

Assessment: Quality of attentiveness, especially student responses to teacher questions.
