Abstract:
Based on the previous research, it was found that the Think Write Pair
Share technique was ineffective in improving students’ critical thinking
skill, and due to the fact that during the process of learning to write
argumentative essay, student commonly encounters various obstacles
at determining the opinion of a topic which should be supported by
logical reasons and appropriate evidences in the form of facts, then this
research aimed at investigating the effectiveness of Toulmin’s model of
argumentation (TMA) within “Claim and Support” strategy on
undergraduate students’ critical thinking ability on argumentative
essay. Thus, this current research employed a quasi-experimental
design with a pretest-posttest and nonrandomized control group
design. Students’ critical thinking ability was measured by a writing test
in the form of argumentative essay test. The data analysis in this
research employed analysis of covariance (ANCOVA). This research
revealed that Toulmin's model of argumentation within “Claim and
Support” strategy was ineffective to improve students' critical thinking
in their argumentative essay.
