E-books before being used in experiments have been declared valid and practical based on expert validation and formative revisions. The effectiveness test of an e- book based on RME results in finding that the average value of student learning outcomes tests that use e-books (experimental class) is higher than the average value of student learning outcomes tests that use printed books (control class). Thus, RME-based e-books can be used as a concrete step for solutions to improve students' mathematics learning outcomes in class VII, choosing the RME approach itself is a form of special effort to make students not only have good mathematical values but the significance of mathematics and feel the benefits of mathematics in life daily. E-books and RME are a good combination in facing the era of competition where most jobs require analytical skills rather than merely performing procedural and mechanistic skills.
