To improve students’ critical thinking is considered as a top priority by a growing number of educators.While there exists a comparable amount of research examining students’ critical thinking skills,less is known about students’ tendency to use these skills.Specifically,little is known about what influence critical thinking disposition has on students’ academic achievement.English reading comprehension,which has been an important composition in students’ English achievement,may be an important factor in developing this disposition.The current study examined the characteristics of students’ critical thinking disposition and their English reading comprehension as well as exploring the correlation between the two factors mentioned above.The current study involved in 125 sophomores in English major from Jiangsu province.The results indicated that students in current research performed best in Maturity (M=37.46,SD=3.57),followed by Inquisitiveness (M=36.64,SD=4.31),Analyticity (M=34.86,SD=3.70),Truthseeking (M=33.86,SD=4.08).In contrast,they performed worst in CT Confidence (M=33.17,SD=4.57),followed by Systematicity (M=33.49,SD=5.10) and Open-mindedness (M=33.50,SD=3.67).Students scored highest in Attitude and View Category as the mean was 0.8257,followed by Reasoning and Judgment Category (M=0.8128),Induction and Generalization Category (M=0.7612),Theme Topic Category (M=0.6844),Semantic Comprehension Category (M=0.6789),while scored lowest in Fact and Detail Category (M=0.5818).There existed a positive correlation between critical thinking disposition and reading comprehension achievement (n=109;r=0.300;p<0.01).
