HOTS on mathematical modelling approach in primary school

Abstract

The 21st-century skills are creativity and innovation, critical thinking and problem-solving, communication and collaboration are accessible through Modelling. This is closely related to HOTS. The problem formulation is, firstly how is HOTS on Mathematical Modelling Approach in a primary school that is valid? and secondly how is HOTS in Mathematical Modelling Approach in Primary schools that are practical? This research uses a development research method which consists of 3 stages, namely analysis, design and evaluation. In the analysis step carried out student analysis, curriculum, and HOTS in Mathematics modelling approach. The second steps is design and product. Then the final step, researchers used a formative evaluation design consisting of self-evaluation, one-to-one, expert review, small group. Subjects in this study were students of SD IT Bina Insani Kayuagung in Ogan Komering Ilir Regency. Data collection techniques are, firstly, walkthrough, this is based on expert review to get tasks valid in content, construct and language aspects of HOTS on mathematics modelling approach in Primary Schools, secondly, interview, this is from one to one, small group to find out the practicality of a Hypothetical Learning Trajectory, and lastly, questionnaire. From expert validation and student answers analysis, we obtained HOTS tasks on mathematical modelling approach in primary schools that are valid and practical using "Jumat Sejahtera" Context.
