Abstract
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. A textbook is needed that can facilitate their needs in learning, namely a textbook that contains additional instructions that can help slow learners understand the concepts of the material more easily. This research is a 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. In this paper only discussed until the development stage, namely validation. Further steps will be discussed in the next article. The data were collected through interviews and validation by the validator, then the data were analyzed descriptively. The results of the preliminary analysis 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 that 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 84.78 with a very valid category. This valid textbook will then be used to be tested in schools to test its practicality.
