This study aims to analyze the validity of the OrDeP2E model of physics learning on sound wave material to train the science literacy skills of MAS Al-Mutaqin Wolowaru students. The learning tools developed were assessed by two people. Validation data were obtained using device ratings with categories 1-4. This study refers to the development of a 4-D model. The validated tools are a) lesson plans, b) BAS, c) worksheets, and d) Science Literacy Ability Test. The results of data analysis that have been validated show that a) RPP scores 3.34 (valid), a) BAS scores 3.52 (valid), c) LKS scores 3.47 (valid), d) tests of scientific literacy skills get a score of 3.70 (very valid). The results of the analysis of the learning tools developed are suitable to be used to improve the scientific literacy skills of MAS Al-Mutaqin Wolowaru students.
