Critical thinking abilities assessment tools: reliability generalization

The purpose of this research was to synthesize the research related critical thinking abilities and to examine the potential impact of variables on the score reliability of critical thinking abilities measurement tools from articles that published on ThaiLIS database during 1988-2008. There were 108 studies that related keyword “critical thinking”. There were only 59 articles that critical thinking abilities were dependent variables and were reported the measure development processes. Reliability generalization (RG) was used to examine the potential impact of variables on the score reliability. Besides the most researchers used conceptual of Robert H. Ennis to develop CTA measuring instruments. In addition the research finding described as the potential impact of variables on those score reliability.
