ANALISIS MISKONSEPSI SISWA KELAS VI SD NEGERI GUNUNG PASIR JAYA PADA MATERI PECAHAN
Full text linkThe concept of fractions is one of the basic materials that students must master since elementary school level. Fractions contain many rules in the form of axioms, definitions, theorems, formulas, and algorithms, this can lead to misunderstanding of concepts by students. Conceptual errors that occur in students due to not understanding the concept are called misconceptions. If there is a student's misconception of this material, it will hinder the understanding of concepts related to fractions, or there can be more misconceptions, and it can lead to a decrease in student learning outcomes. The purpose of this study is that teachers can find out early on any misconceptions related to fractions that often occur so that teachers can evaluate and correct these misconceptions. The method used in this research is the descriptive method. Data collection techniques in research using description tests and data analysis techniques by reducing data. From the data, it was found that most students experienced misconceptions in the sub material of basic fraction operations, namely the addition and multiplication of fractions. However, in almost all sub-materials, more than 50% of students experienced conceptual errors. The most common type of misconception is using the wrong concept in applying the concept to a certain procedure or operation.Keywords: elementary school; fraction; misunderstandingDOI: http://dx.doi.org/10.23960/mtk/v9i2.pp211-22
