Abstract
This research aimed to increase the critical thinking ability of the students by using visual thinking technique. The critical thinking ability of the students was measured by 6 indicators, in which five of these indicators measured the students’ cognitive ability through analyzing, describing, interpreting, evaluating, and inferring activity, while the other indicator measured the students’ affective ability of self regulation. The research approach used was Classroom Action Research involving 40 students of Class 2C at Yogyakarta State University as the research subjects. The instrument used in this research was written test in the form of free essay, interview, and Guttman’s Attitude Scale. The data were analyzed by using qualitative and quantitative techniques. The qualitative technique was used for data description, while the quantitative technique was used for the percentage descriptive analysis. The result of the research showed that the use of visual thinking technique made the students’ critical thingking was increase for all indicators, namely the ability of analyzing (75.8% or high), describing (61.7% or low), interpreting (60.0% or low), evaluating (66.7% or moderate), inferring (73.3% or high), and assessing self-regulation by themselves (75.7% or high).
