In this research, the critical thinking dispositions of secondary students were investigated. The descriptive survey model was used in this research. The research sample is made up of 303 8th grade students receiving education in 2018-2019 academic year at three secondary schools in Adana. The Critical Thinking Disposition (CTD) Scale developed by Ricketts & Ruds (2005) and adapted into Turkish by Demircioğlu (2012) was applied to students selected with unbiased cluster sampling method. The arithmetic mean, standard deviation, p and t values of scores reached from Critical Thinking Disposition (CTD) Scale was calculated. Independent groups t-test to determine if differences are significant or not and Pearson Product-Moment Correlation Analysis was used for evaluating the relationship between variables. Critical thinking dispositions by gender are not significant in Cognitive Maturity, Innovativeness and scale total, however they are significant in Engagement dimension in favor of female students. * Doktora Öğrencisi, Çukurova Üniversitesi, Eğitim Fakültesi, Eğitim Bilimleri Bölümü PhD Student, Çukurova University, Faculty of Education Sciences, Department of Education Sciences 0000-0002-8698-8595 cemilelci@gmail.com ** Doktora Öğrencisi, Çukurova Üniversitesi, Eğitim Fakültesi, Eğitim Bilimleri Bölümü PhD Student, Çukurova University, Faculty of Education Sciences, Department of Education Sciences 0000-0001-8980-2218 filiz.tuncel01@gmail.com *** Doktora Öğrencisi, Çukurova Üniversitesi, Eğitim Fakültesi, Eğitim Bilimleri Bölümü PhD Student, Çukurova University, Faculty of Education Sciences, Department of Education Sciences 0000-0003-2745-2683 brcdmrglri@gmail.com **** Doktora Öğrencisi, Çukurova Üniversitesi, Eğitim Fakültesi, Eğitim Bilimleri Bölümü PhD Student, Çukurova University, Faculty of Education Sciences, Department of Education Sciences 0000-0002-5243-9918 pinar_akman01@hotmail.com ***** Bilişim Teknolojileri ve Yazılım Öğretmeni, Milli Eğitim Bakanlığı Information Technologies and Software Teacher, Ministry of Education 0000-0002-0870-4008 merveelci@gmail.com ****** Doç.
