The outcomes for the 13 correlations across the subscale pairs are shown in Table 1. Development of a more flexible physical science laboratory program for non-science majors with superior high school science backgrounds, final report. Pin It on Pinterest. This paper describes a two part analysis of the psychometric properties of the WGCTA, based on 13 sets of subscale inter-correlations and 60 sets of subscale means retrieved from published studies. Consistently low correlations, if their individual reliability estimates are reasonable high, suggest that the subscales are likely to be separate measures of the constructs.
We chose to examine the psychometric properties of the Watson—Glaser Critical Thinking Appraisal WGCTA , as a case in point, because it is the oldest and perhaps the best known and certainly the most widely scrutinized of the CT standardized tests. Deduction and interpretation were the highest loading subscales reversed on the two versions and assumption and evaluation were the lowest also reversed. Evaluating critical thinking skills in a scenario-based community health course. This procedure gives more weight to large samples as compared to small samples. In other words, the true population correlations could be higher or lower than the ones observed. This fact makes interpretation of the average correlations problematic. Wagner and Harvey argue that the response format of the WGCTA may account for some of the reliability problems noted above.
Watson-Glaser Critical Thinking Appraisal (WGCTA)
Teaching watson-gllaser learning critical thinking skills. While there is little doubt as to the desirability of teaching students to think critically, the concept of critical thinking, as we have examined it here, is a slippery one, both in terms of definition and measurement.
In Paper presented at the annual convention of the international reading association. Interpreting the CCST, group norms and sub-scores technical report 4.
Dissertation Abstracts International, 62 10A. The california critical thinking skills test—college level: An investigation of the critical thinking ability of associate and baccalaureate degree nursing students.
Overall the average correlations ranged from a low of 0. Factor analysis of critical thinking, logical reasoning, and English subtests.
If successful guessing is a problem with interpretation of the general score on the WGCTA, as Watson and Harvey claim, it is further exacerbated at the subscale level where fewer items are involved. The latest, the WGCTAs, was revised in and is a short form containing 40 items that can be administered in 45 min. Critical thinking in preclinical examinations.
Dissertation Abstracts International Section A: This paper describes a two part analysis of the psychometric properties of the WGCTA, based on 13 sets of subscale inter-correlations and 60 sets of subscale means retrieved from published studies.
In other words, the true population correlations could be higher or lower than the ones observed. Subsequently, we conducted principal components analysis on 60 subscale means of two different versions of the WGCTA.
Factor analyses of three tests of critical thinking. On the other hand, perhaps we may need to develop new methods of evaluating critical thinking, which are sympathetic to views watsln-glaser posit the existence of separate sub-skills.
Watson-Glaser Critical Thinking Appraisal (WGCTA) – Statistics Solutions
These results do not completely undermine the theoretical work of Facione a,b and others who posit the existence of finer-grained sub-skills, and they do not apprqisal out the existence or importance of the CT dispositions hypothesized by Facione.
Contemporary Educational Psychology, 4 3— The Standard Version takes about 60 minutes to administer. Journal of College Student Development, 31 6— In this study, we are investigating whether watson-glaseg claim is even warranted—Can the subscales in the WGCTA be discriminated from a psychometric perspective at the group level?
An approach to teaching problem solving in the classroom.
This procedure gives more weight to large samples as compared to small samples. Humanities and Social Sciences, 58 7A. Since the WGCTA is marketed and used as a predictive measure in a wide variety of educational and vocational contexts, and is sometimes used for the academic placement of individuals and for other diagnostic purposes, it would be useful to know if the individual subscales can be interpreted, or whether the general score is the only meaningful outcome. The full version of these dissertations can be found on ProQuest.
In the test manualthe authors of WGCTA do not encourage the use of the subscale scores for individual prediction or diagnosis, because the number of items in each subscale is small and therefore lacks sufficient reliability.

Number of items correct and performance on each scale are reported in addition to an overall percentile and a brief narrative interpretation. By publisher policy, this assessment is only to be administered in a proctored setting.
Journal of Educational Research, 55 6— The wealth of published data on it allowed us to investigate the psychometric properties of the WGCTA subscales in two different ways to determine if there are, indeed, separate and identifiable subscales, or if the test is best scored and interpreted as a general measure of CT.
The right to participate—20th yearbook of the National Reading Conference pp. What they likely do say is that discriminating among these sub-skills, from a psychometric perspective, is difficult to do.
