Fractions Textbook for Slow Learners

Abstract

Fraction is a material that is difficult to understand because it contains concepts that are classified as abstract for elementary school students, including slow learners. Therefore, a textbook is needed that can facilitate their learning needs, namely, a textbook that contains additional instructions that can help slow learners understand the concepts of the material more easily. This research is development research that aims to develop a textbook for slow learners, especially on fractions. The development procedure used is the ADDIE model with the following steps: analyze, design, develop, implement, and evaluate. Analyze steps have been discussed in the previous article. This paper only discussed the design and development stage (namely validation). Further steps will be discussed in the following article. The data were collected through interviews and validation by the validator, and then the data were analyzed descriptively. The preliminary analysis results show that a textbook is needed to help slow learners understand fractions. At the design stage, a textbook is designed according to the needs of slow learners, namely textbooks that contain instructions to make it easier for slow learners to learn. Then, the books that have been designed are validated by experts. The validation results show a percentage of 78.5% with an outstanding category. This good textbook will then be tested in schools to test its practicality.
