摘要：This research aims to determine the leve l ing of critical thinking abilities of students of mathematics education in mathematical problem solving. It includes qualitative - explorative study that conducted at University of PGRI Semarang. T he generated data in the form of information obtained problem solving question and int erview guides . The r esults are : (1) students who are not critical ( LCTA - 0) only able to identify the gi ven facts clearly , (2) students are less critical ( LCTA - 1), students can identify the facts in problems, (3) critical student ( LCTA - 2), students can iden tify the fact in problems, revealing the prerequisite knowledge appropriately , solve the problem but still less accurate in every stage, and (4) students are very critical ( LCTA - 3), students can identify the facts given clearly, mention the concept/ theore m/ prerequisite material . Based on these results, the leveling of students critical thinking abilities can be applied in a lecture at mathematics education.
