Saif (2007) concludes that “…in measuring the students’ performance, teachers should design items which
encourage understanding, judgment and critical thinking of learners, so that the learners understand the concepts and
subjects through a deep approach. Beside the casual tests, teachers had better provide students with homework
which need higher mental activities and ask the learners to do these activities for learning (p.629)”. In mathematical
instructions, the teacher should try to apply methods which promote the students problem-solving skills and its
instructional the subject. This judgment ability and the review of the previous method could be raised in the
students' minds and the teacher should avoid giving the homework which was explained completely in classes and
those which don’t require any creative mental activities. Unfortunately some teachers and mathematics lectures use
the items in test which were answered during class sessions and this leads to the surface studying approaches among
students.
