            5.3.1    Method of Carrying Out the Study
            The preliminary exercises done through observation, interview and pre-test were able to
            show the need for intervention particularly to help students' mastery in solving first order
            linear differential equation. In  response, the researcher designed  the "KIMCI  CERIA"
