The Development of Additional Lessons Toward the Enhancement of Basic Geometrics Knowledge for 1st grade Students with Learning Disabilities Based on Gagne’s Principle with Multimedia

Abstract

The purposes of this research were 1) to analyze the need for basic mathematics knowledge of students with learning disabilities, 2) to design and develop multimedia to enhance basic geometrics knowledge based on Gagne’s principle for students with learning disabilities, and 3) to study basic geometrics knowledge of students with learning disabilities, pre-test and post-test learning using knowledge enhancing lesson with multimedia. The experimental group was 10 students with learning disabilities in the 1^st grade level. The tools that were used in the research were the basic competency assessment form, multimedia, lesson plans, and the basic geometrics knowledge test form, using the one-group pretest-posttest design. The findings found that 1) the essential need for basic knowledge of mathematics of 1^st grade students with learning disabilities should receive the most was geometry, 2) The design and development of multimedia to enhance basic geometrics knowledge consisted of the following elements: lesson page, lesson instruction and objectives page, pre-test pages, learning resource pages, game page, post-test pages, and menu page with a tool fitness value of 0.95, and 3) The basic geometrics knowledge score of learners with learning disabilities after learning were higher than before, significantly at .05.
