The center for critical thinking is located at Sonoma State University and it provides basic information on critical thinking as well as useful resources and references, and also has an archive of on going discussions. The critical thinking assessment seeks to develop and make available an adequate, modular instrument for the assessment of critical thinking competence both generally and in the contexts of specific disciplines. It consists primarily of employing a set of techniques whose purpose is exclusively evaluative.
Critical thinking involves several elements which include the purpose for thinking, question at issue, concepts, assumptions, information, interpretations and inferences, points of view, consequences and implications. It also includes the elements as observations which can be established, from a series of facts or from an absence of fact, testing the validity of inferences, from our assumptions, opinions, and to challenge the arguments of others which we are analyzing.
The elements of critical thinking makes students think or to know the difference between reliable and unreliable observations, to be persistent enough to observe objectively, to see the patterns or relationships in what they have observed in their reading, to assume carefully, to form opinions and to create arguments.
Critical thinking skill is understood as one of those capabilities that can be developed intentionally to optimize performance and the primary aim is to encourage students to observe themselves and others in the critical process.
