Use of Autograph Learning Media to Improve Mathematic Communication Skills

Abstract

The use of learning media is one way to support the government in socializing the era of industrial technology 4.0. Learning media as a solution to students' low mathematical communication skills. One of the learning media that is proven to be able to improve students' mathematical communication skills is Autograph. This paper describes how much influence the use of Autograph learning media has on students' mathematical communication skills. The method used in this research is experimental. Before using the Autograph learning media, a pre-test was carried out and after using the Autograph learning media, a post-test was carried out to determine the increase in students' mathematical communication skills. From the results of the pre-test and post-test data analysis, it was found that the Autograph learning media had a positive effect on mathematical communication skills. The average of students' mathematical communication skills taught with the help of Autograph media was higher. The use of Autograph learning media in learning makes students more active in discussions, dares to express opinions using mathematical language to express mathematical ideas correctly and can interpret mathematical data in the form of pictures or graphics.
