Critical Thinking

Critical thinking is reflective thinking focused on deciding what would be sensible or reasonable to believe or do in a given situation. It involves creative activities such as formulating hypotheses, gathering pertinent information, recognizing assumptions and values, comprehending and interpreting data, evaluating arguments, recognizing relationships, drawing and testing conclusions, and rendering judgments based on appropriate criteria. Helping students think critically involves inviting them to assess the merits of various options before them on the basis of relevant factors. It is a powerful method of teaching content, skills, and outcomes.
In order to engage students in critical thinking, teachers must provide a supportive learning environment where reflective inquiry is valued. Examples include classroom routines requiring students to engage and think through problematic situations; opportunities for critical dialogue and debate; and self/peer assessment activities.
Intellectual tools for critical thinking can be purposefully taught and assessed. More information about these skills and criteria for assessing students’ critical thinking are available in some of the links below.
