This research aims to design a learning model that can train Higher Order Thingking Skills (HOTS) and foster a sense of nationalism in students by using a problem based learning (PBL) model based on realistic mathematics education (RME) and ethnomatics. This learning model is named PBL-Reathnomath which will be tested for its feasibility through the content validation and limited trials. This study used the Plomp development design with the following steps, 1) initial investigation, 2) design, 3) realization / construction, 4) testing, evaluation, revision, and 5) implementation. The research subjects were elementary school students of VI Class in West Aceh and the opinion of elementary school teachers in implementing the model. The learning tools used were learning model guides, lesson plans, student worksheets, and modules. In addition, the preparation of assessment instruments consisting of HOTS tests, questionnaires, syntax feasibility assessments, questionnaires user response, and preparation of validation sheets. The results of the research can be concluded that the PBL-Reathnomath learning model is feasible to be applied to students and educators candidate in developing learning models. Based on the assessment of the validator, the learning model has met the content validity with a Vaiken value $\geq$ 0.76, and the teacher and student assessments are in the “Good” category. Learning uses the PBL-Reathnomath model is feasible to be tested to assist in training students’ HOTS.
