The Development of Learning Device Based on the Discovery Learning Model Which is Oriented with Natural Disaster Mitigation Towards Mathematical Analyzing Ability of Pupils in Grade VIII of Middle School

Abstract

This study aims to produce mathematics learning media based on the discovery learning model, which is oriented to natural disaster mitigation towards the mathematical analyzing abilities of grade VIII in Junior High School students. This media was developed based on the results of a mathematical analyzing skills test and the results of a questionnaire on disaster mitigation at MTsN 1 Padang. Based on the results, it can be concluded that the mathematical analyzing abilities of students were still very low by the achievements of 20.7%. However, in natural disaster mitigation, the survey results showed that 88.9% of MTsN 1 Padang students showed that there was no socialization and learning treatment about natural disaster mitigation. This research is development research. The development model used in this research was the Plomp model, which consists of three phases: preliminary research, prototyping phase, and assessment phase. The results of the analysis of the data based on the lesson plan (RPP) and (LKPD) validation sheets showed that the mathematics Learning media based on the discovery learning model which oriented to natural disaster mitigation on the mathematical analyzing abilities of students have been valid in terms of construct and content and have also been practical in terms of implementation and easiness of use. which an average of 80.3% and it was also effective for improving students' mathematical analyzing abilities by achievement of 73.84%.
