Besides, it aims to determine students' calibration skills through this scale. Results of the study revealed that fifth-grade students [n = 94] enrolling to study, have a medium-high level of [M = 55.12, SD = 21.76] mathematical calibrations skills. Furthermore, the results showed that students' mathematical calibration skills do not show significant differences with respect to their gender [t = .501, p > .01]. However, students' calibration skills show significant differences when considering their level of mathematics achievement [F12-91 = 69.46, p < .001, pi(2) = .60]. In addition, a positive and significant relationship was found between students' mathematical calibration skills and their mathematics achievement [r = .85, p < .001].trinfo:eu-repo/semantics/openAccessMathematical CalibrationCalibrationMetacognitionItem-Specific CalibrationCalibration MeasureArticle12211901194
