Development of interactive multimedia to overcome difficulties in isomorphous binary phase diagram learning materials

Abstract

This research is motivated by the difficulties faced by students in the learning process of the Engineering Materials subject, which is shown by preliminary data that 63% of 30 students have difficulty in learning the subject of phase diagrams, of 63% of students by 50% have difficulty in mastering the material for the calculation of phase diagrams, as many as 30% of students have difficulty in drawing phase diagrams, and 20% have difficulty in others. This is due to the difficulty of understanding abstract, complex and dynamic concepts, so that it impacts on the low student learning outcomes due to the ineffective mastery of concepts. The purpose of this research is to produce interactive multimedia that is suitable to be used as learning media for Isomorphous Binary Phase Diagrams to facilitate students in overcoming the difficulty of concept mastery. Interactive Multimedia development method uses the DBR method and the research method used was a quasi-experimental research method with one group pretest-posttest design. The sample used in this study was 45 students as an experimental class. The results showed that interactive multimedia was feasible to use and could overcome the difficulty of mastering the concepts of students in Isomorphous Binary Phase Diagramsh.
