The Validity of Enactive Iconic Symbolic Problem Based Learning Model (PBMENI KSI) for Elementary School

The purpose of this research was to produce a practical, valid, and effective Enactive Iconic Symbolic Problem Based Learning model (PBM-ENIKSI) for elementary school fourth grade students. This research produces several products as model books, teacher books, and student books. The research design developed by Plomp consists of three stages, namely preliminary research, development or prototyping phase, and assessment phase. The preliminary research stages are analyzed by needs analysis, student analysis, curriculum analysis, and concept analysis. The development or prototyping phase was conducted by doing self evaluation, expert validation, one-to-one evaluation, and small group evaluation. As in the assessement phase, a large group field test was conducted through an Enactive Iconic Symbolic Problem Based Learning model (PBM-ENIKSI) for elementary school fourth grade students. Based on the results of product validity by expert validation, the data obtained results in a very valid product.
