Abstract

This research aims to describe the increase in students^ mathematical spatial abilities after implementing digital teaching materials in three-dimensional material. The digital teaching material used in this research is the GeoGebra Book. This research is quantitative descriptive research with 28 class XI students at one of the Ciamis Regency vocational high schools as research subjects. The research instrument consisted of a mathematical spatial ability test and a student response questionnaire. Analysis of mathematical spatial ability test data uses the Gain Normalization test, while analysis of student response data uses the rating scale calculation formula. Based on the research results, it was found that: (1) there was an increase in students^ mathematical spatial abilities in three-dimensional material after using GeoGebra Book by 0.57 with the interpretation of a moderate increase- and (2) students^ responses to the GeoGebra Book on three-dimensional material are in the good category.
