Analysis of the Difficulty of Understanding the Concepts of Vibration and Waves of Students Junior High School

Abstract

This research starts from the problem of low student physics learning outcomes. This is because students have difficulty understanding the concept, because it is also necessary to analyze the difficulties. The purpose of this study was to find out what forms of difficulties were experienced by students at each stage of students' abilities in understanding the concepts of vibration and waves, which difficulties at which stages of student ability were most dominantly experienced by students in the concept of vibrations and waves, and difficulties experienced by students in solving math problems. The subjects of this study were 32 students of class VIII SMP Negeri 2 Way Seputih to determine the sample using the cluster random sampling method. based on the analysis it can be concluded that the forms of difficulties experienced by students at the student's ability stage, the most dominant difficulty is at the C6 stage with a percentage of 100%, and the percentage of difficulties experienced by students in working on calculation questions is 60%. It can be seen the forms of difficulties experienced by students, so to overcome these difficulties the teacher should familiarize students more with solving their respective practice questions, especially questions of understanding and application.
