Direct learning models assisted by Lectora Inspire media to improve the understanding of geometry concepts

Abstract

This study produced a learning device using a direct learning model assisted by lectora inspire media to help improve students’ understanding skills in good quality geometry material. Development of learning devices using a modification of the Thiagarajan 4-D model. The research subjects were 18 first semester students in Geometry class. Learning tools produced in this study are Lecture Program Units, Learning Outcomes Tests, and Lectora Inspire learning media with the direct learning model syntax. The lecture device used in this study is said to be valid based on the results of validation by the validator. Learning devices also have practical criteria based on the percentage of 90% of lecturer activity at the first meeting and 93% at the second meeting. Learning devices are said to be effective based on the results of student tests which show more than 80% of students get high scores which show that students’ understanding increases, so this learning device is very helpful for students in understanding geometric concepts specifically in triangular congruence material.
