DEVELOPMENT OF LIGHT TEST BOARD (LTB) MEDIA TO IMPROVE STUDENTS' LEARNING OUTCOMES IN PRIMARY SCHOOL

Abstract

Science learning about the natures of light was an abstract and needed activities skills of science. Science learning needed the learning media that must be researched and developed. This study described the development of the Light Test Board (LTB) learning media, described the application of media in learning, and described the improvement of student learning outcomes. The Light Test Board (LTB) learning media designed with research and development. Development activities used 4D models, that was Define, Design, Development and Dissemination. The expert validated Light Test Board (LTB) learning media. The results of the validation test shows the percentage of 91.5%, it means that the Light Test Board (LTB) learning media is feasible and valid in learning. The author observed the Light Test Board (LTB) learning media in learning. The results of the observation shows a percentage of 93% for the use of learning media by teacher, it means that the Light Test Board (LTB) media can be used properly, and is able to increase students' learning activities in the aspect of process skills and attitudes with a percentage above 82%. Assessment of learning outcomes in the aspect of knowledge after learning using the Light Test Board (LTB) learning media shows an increase in student learning outcomes by 18% based on the percentage of the number of students who completed learning and the average grade of the class increased to 86. So, the Light Test Board (LTB) learning media can improve student learning outcomes
