Abstract
This study aims to produce a development product in the form of a contextual learning development design and learning tools (syllabus, lesson plans, student worksheet, and mathematical representation ability tests) that are valid and practical to improve students' mathematical representation skills. This research is a Research and Development (R&D). The R&D stage starts from research and information-collecting, planning, developing preliminary of product. This research was conducted at SMP Al-Huda Jatiagung South Lampung in the odd semester of the 2020/2021 school year. The subjects in this study consisted of 2 experts (design, material, and media) validation tests, 2 teachers and 5 practitioner test students (responses), and 14 students who tested the mathematical representation ability test analysis. The research data were obtained from interviews, expert validation questionnaires, teacher and student practitioner questionnaires, and students' mathematical representation ability tests. The development of contextual learning and learning tools is valid according to experts, and practical according to teachers and students. The results of expert validation tests on product development get a mean score 85.30% with valid criteria, and the results of the teacher practitioner test of the learning device got a mean score of 82.25% with practical criteria, and the results of the mean score of student assessments on LKPD were 79.80% with practical criteria.
