Mathematics Teaching Videos with the Context of Riau Culture to Enhance the Mathematical Problem Solving Ability of Class VIII Students on the Material of Polyhedron

Abstract

This development research is based on low ability of students to solve mathematical problems (Mathematical Problem Solving Ability or MPSA) and the lack of learning devices which can be used as solution for these problems. This research was originally aimed at developing learning devices which is syllabus, lesson plans (LP), and student worksheet (SW). Due to the Covid-19 pandemic outbreak and online learning must be taken, the learning is supplemented with the preparation of learning videos. The development model used refers to the Borg & Gall model, but it has not gone through all phases. The phases that were completed: research and data collection; plan; development of initial product designs; first field trials; and product revisions. The following stages whose implementation requires formal classes cannot be performed. The resulting products are in the form of syllabus, lesson plans, student worksheet and math learning videos using the discovery learning model with Riau's cultural context on the Polyhedron material. Validity and practicability measurement was performed for syllabus, lesson plans, and student worksheets, while learning videos used directly. The results showed that the learning devices were categorized as valid and very practical for improving MPSA.
