Validation of Teaching Materials for the Blended Learning Model of Applied Mathematics for Polytechnic Student

This study aims to determine the level of validity of applied mathematics electronic teaching materials for the blended learning model in the form of modules (E-Modules) and student activity sheet (E-SAS). The research used the 4D model development method, carried out at the Politeknik Negeri Bali (PNB). Data were collected using validation sheets, student response questionnaires and analyzed descriptively. The results of the analysis show that the E-Module and E-SAS applied mathematics are quite feasible, very practical and very useful for blended learning models. E-Module and E-SAS need to be refined. The development process can be continued to the stage of effectiveness testing, evaluation and dissemination. But before that it needs to be refined.
