Abstract

This study describes the methodology used by Marcos Y. Lopez of the Centro Escolar University in developing and validating The CEU-Lopez Critical Thinking Test. The test is a multi-aspect general-knowledge critical thinking test designed for Filipino students in tertiary level. It uses Ennis’s conception of critical thinking in the development of test items. The use of verbal reports of thinking to establish validity and fairness of multiple-choice critical thinking test is based on the study by Norris in validating his co-authored Test on Appraising Observations. Verbal reports of thinking are useful in establishing validity and fairness of multiple-choice critical thinking tests for they provide evidence to judge whether good thinking is in general associated with choosing answers credited by the key as correct and poor thinking is associated with choosing unkeyed answers . The eight processes employed in developing and validating this multiple-choice critical thinking test are as follows: test conceptualization, development of a test plan, development of test items, face and content validation of the test, revision of the test items, pre try-out of the test, actual try-out of the test, and construct validation of the test using verbal reports of thinking. The CEU-Lopez Critical Thinking Test consists of 87 items that focus on five aspects of critical thinking: deduction, credibility judgment, assumption identification, induction, and meaning
