Student’s Mathematical Communication Skills in Class VII Sets Materials Through HOTS-Based Learning

Abstract

Students need to have good mathematical communication skills when studying set material. The use of HOTS-based learning can be applied in learning activities so that students have good mathematical communication skills. This study aims to determine and describe mathematical communication skills after the learning process using HOTS-based learning in class VII set material is carried out. This study uses a descriptive type of research. The subjects of this study were students of class VII-3 SMP IT Al-Fatah Mekar Jaya, totaling 27 students. Data collection techniques are observation, a written test consisting of 3 test questions, and interviews. The data analysis technique is data reduction, data presentation and conclusion drawing. The results obtained from this study are students' mathematical communication skills after the learning process using HOTS learning on the set material for class VII-3 SMP IT Al-Fatah Mekar Jaya is in the medium category, with the average percentage is 39.19%. The indicator that appears the most is "explaining ideas, situations, and mathematical relations, orally and in writing with real objects, pictures, graphs, and algebra and indicators stating everyday events in mathematical language or symbols", while the indicators that appear the least is "connecting real objects, pictures, and diagrams into mathematical ideas". The use of HOTS-based learning can make students have good mathematical communication skills.
