Abstract

The capability ofthinking critically ofthe students ofUMMY Solok is still low on the subject Evaluasi Pembelajaran Matematika. From the previous research on this matter, the students tended to be passive on the process of learning in class, as the impact most ofthe students was still not able in collecting, analyzing, synthesizing the objects of the lesson, drawing conclusion from the object of the lesson, assessing and correcting the objects of the lesson with the right argumentation, and to solve the problem on the objects of the lesson.
