Identifying K-10 Students’ Learning Difficulties on Learning Kepler’s Law using Worksheet: Is It Worth?

Abstract

This study set out to identify K-10 students’ learning difficult when they learn about Kepler’s Law. The research method utilized in this study was the single-intrinsic case study. The subject of this study was 19 students of one of a private school in Cianjur, Indonesia that consist of 12 females and 7 males from people with a background were mostly merchant. Students’ worksheet was used to identify students’ learning obstacles. Through the qualitative analysis of student answers to student worksheets, it can be found that students’ learning difficulties when learning Kepler Laws in the form: 1) understand the physical meaning of First Kepler’s law, 2) identify and discover the relationship of physical quantities that work planets when interacting with the sun, 3) perform mathematical operations to derivate the Kepler’s third law equation and apply it in some cases. Through this analysis, we can identify K-10 grade students’ learning difficulties when learning Kepler’s Laws.
