Abstract

This research aims to find out whether the LKPD is based on problem based learning on statistica material to improve the problem solving abilities of class VII students in a feasible, practical and effective way in the learning process. This research uses the Research and Development (ReDi research method with the ADDIE (Analyze. Design, Development, Implementation. Evaluation) model. The research instrument uses validation sheets, questionnaires and tests. The results of this research indicate that the LKPD based on problem based learning to improve students' problem solving abilities that has been developed is valid and feasible to apply with a percentage of 94% (media experts) and 84% (material experti). The LKPD was also stated to be practical at seen from the teacher response questionnaire with a percentage of 100% and the student response questionnaire of 91.78% The LKPD was declared effective as seen from the N-Gain score of 0 6632 in the "High" category. Students' problem solving abilities also increased as seen from the prelest results of 58.75% (Poor) and posttest of 81.41% (Very Good). Based on the research results, it can be concluded that problem-based learning LKPD to improve the problem-solving abilities of class VII students has been developed which is feasible, practical and effective to use. The developed LKPD can increase students' learning activities and teachers can use LKPD as teaching materials In the learning process. is a brief overview of the entire content of the article so that it contains Background

Abstract

Kemampuan seorang guru dalam mengajukan pertanyaan yang berkaitan dengan Kehidupan sehari-hari  di kelas sangatlah penting. Tujuan penelitian ini adalah untuk mendeskripsikan dan menganalisis keterampilan pemodelan matematis siswa ketika mengerjakan tugas matematika terkait situasi.Pembelajaran ini dianggap penting.Sebab, syarat belajarnya mengharuskan Anda memiliki kemampuan berhitung yang baik, serta mampu menerapkan matematika dalam kehidupan sehari-hari.Oleh karena itu, keterampilan pemodelan matematika penting bagi siswa sebagai jembatan antara masalah matematika dengan dunia nyata.. menjadi Peneliti mendapat alat berupa soal matematis kontekstual, setelah itu peneliti menganalisis hasil penelitian dan melakukan wawancara terkini mengenai hasil kerja alat tersebut.Hasil penelitian ini menyimpulkan bahwa kemampuan pemodelan matematis siswa berbeda-beda, terlepas dari apakah mereka mempunyai kemampuan matematika tinggi, sedang, atau rendah.Masih terdapat siswa yang tidak membangun model matematika karena kurang memahami permasalahan.Bahkan ketika siswa memodelkan gambar membuat banyak variasi, namun sebagian besar siswa masih mempunyai ketelitian yang rendah dalam memodelkan gambar sesuai tugas yang diberikan.Sebagian besar siswa masih kurang pengetahuannya tentang pemodelan matematika.
