ABSTRACT
This study aimed to describe the development of interactive whiteboard media with the learning model Realistic Mathematic Education (RME) in improving mathematics learning outcomes in early childhood. This study used the Borg and Gall development method with step 6, which is a limited test. The results of this study found an average rating of 89.25% by media experts and 85.75% by material experts, which indicated that the media product interactive whiteboard with the learning model RME was very valid for use in kindergarten. An average teacher response of 88.50% and an average student response of 84.50% means that teachers and students, in general, assess this product as very practical to use in learning mathematics in class. The average posttest results in the experimental Kekancan Mukti Semarang kindergarten class were better than for the control class, that is, 76.75 > 72.75, and t arithmetic > t table is 2.36 > 1.70, so that this product is effectively used as a learning medium in PAUD children.
