摘要：This study aims to: 1) Obtain discovery-based learning with SAVI approach assisted by GeoGebra (DLSG) that meet validity, practicality, and effectiveness criteria; (2) Describe the improvement of mathematical communication skills (MCS) of the students taught through DLSG; (3) Describe learning motivation of the students taught through DLSG. This research is a development research conducted in two stages, the first stage is developing a DLSG based learning device, the second stage is implementing a DLSG based learning device at grade IX senior high school students MTs Aisyiyah Medan. The learning devices produced from this research are: Learning Implementation Plan (LIP), Teacher's Book (TB), Student's Book (SB), Student Worksheet (SW) and MCS test. The results of the research are: (1) the DLSG-based learning devices developed have met the validity, practicality, and effectiveness criteria; (2) there is the improvement in MCS of the students taught through DLSG. The average MCS score in trials I and II were 81.82 and 94.12; (3) there is the improvement in learning motivation of the students taught through DLSG, the motivation score increased from 85.97 to 86.20.
