This research aimed to determine the difficulties that the students experience in inequality solutions that contain
inequality in general and rational (proportional) expressions, and to solve these difficulties with an activity. Totally
108 students, who were enrolled in the Department of Mathematics and Science Education, consisted respectively
of 43 in the 2015-2016, 32 in the 2016-2017, and 33 in the 2017-2018 academic year, participated in the research. It
was started with an activity to make students realize the difficulties they experienced and become aware of the
stages which they had difficulty. After the activity, the difficulties, and the stages that students had difficulties
were determined. At that point, they were informed about the solutions for the difficulties they faced and shown
a road map for coping with the stages they had difficulties. At the end of the research, the rational inequality
questions were asked to the students in the mid-term and/or final exams, and it was observed that the majority of
students did not experience any of the problems which they had experienced before the activity. Another result of
the study was that the students had less difficulty in the inequalities related to the concept of greatest integer,
which they received only in university education.
