Media Jam Sudut (Jasut) : Solusi Pembelajaran Matematika di SD Negeri 110 Lura

Abstract

Mathematics education is often considered difficult and boring learning. One of the causes is the lack of creative learning models, so teachers must use learning models that can rejuvenate student learning motivation, for example by using props such as props that the author has prepared, namely corner clock props. Corner clocks are a medium for teachers to make math learning more interesting and fun.  The introduction of angular clock props (jasut) aims to help teachers explain abstract mathematical concepts in geometry material, namely the relationship between time and angle magnitude. This activity used several methods, namely the demonstration method, practice method, question and answer method, and evaluation method with 11 respondents at SD Negeri 110 Lura. The evaluation results showed that the angular clock learning media (JASUT) was able to improve teachers' understanding of the concept of angles and was relevant to be applied in mathematics learning, with an average teacher response of 85.5%. This finding confirms that JASUT is effective as a tool in explaining geometry materials in elementary schools.
