Studying in higher education, learners are expected to gain not only knowledge but also higher-order thinking
skills. The skills can help learners coping with problems in daily life, as well as applying and using their knowledge
in their professionals effectively. Growing higher-order thinking skills requires critical thinking as a basis of
development (Kham Mani et al. 2001). In other word, if learners have inadequate critical thinking, they will have
difficulty in developing their higher order thinking skills. Therefore, to develop learners’ higher order thinking
skills, the institutes of higher education should train their learners to extend critical thinking skill through their
learning and teaching process (Sunsern, 1997).
