Development of Mathematics Learning Devices by Applying Problem Based Learning to Increase Students Mathematical Solving Skills of Class VII Junior High School

Abstract

This research was motivated by the low ability of Mathematical Problem Solving (KPMM) of students. In order to improve KPMM, teachers can do designing the learning process. This study aims to develop mathematical learning tools that are valid, practical and effective. The development model used the Borg and Gall model. The research instrument consisted of syllabus validation sheets, lesson plane (RPP), student worksheet (LKPD), observability of implementation, student questionnaire responses and KPMM test instruments. The result shows the mathematics learning kit using the PBL model was already valid which is for the syllabus was 85.41%, RPP was 85.11%, LKPD was 88.67% and the test instrument was 81.71%. The learning kit fulfills the practicality requirements in large group trials with an average questionnaire of students responses of 91.99% and an average of 94.58%. Effective mathematics learning tools is to improve KPMM of students with student learning outcomes that is based on the achievement of KKM with the percentage of completeness reached is 88.24%. Development of learning tools can significantly improve students mathematical problem solving abilities at a significant level of P = 0,000 with α = 0.05. Thus, it can be concluded that the development of mathematics learning tools by applying problem based learning can improve students mathematical problem solving abilities

Pengembangan Perangkat Pembelajaran Matematika Berbasis Problem Based Learning Materi Sistem Persamaan Linear Dua Variabel Untuk Memfasilitasi Kemampuan Pemecahan Masalah Matematis Siswa Kelas VIII SMP/MTs

“…Berbagai masalah yang guru hadapi saat menyusun perangkat pembelajaran antara lain menurut Radeswandri (2021), Atika, Roza dan Murni (2020), Fitria, Hutapea, & Zulkarnain (2020) dan Putri, Roza, & Maimunah (2020) Problem Based Learning merupakan metode mengajar siswa bagaimana berpikir kritis dan memecahkan masalah menggunakan konteks masalah dunia nyata (Sumartini, 2016). Problem based learning, menurut Nurzazili, Irma, & Rahmi (2022), mendorong partisipasi dan kolaborasi siswa sehingga mereka dapat menjadi pemecah masalah yang mandiri.…”

Teacher Assistance in The Development of Merdeka Curriculum Learning Devices

“…The materials are created with a focus on administrative requirements provided by the teachers without considering the intended learning objectives (Atika et al, 2020). Teachers also face difficulties in designing Student Activity Sheets (LKPD) that can help students discover their own concepts about the material being studied (Fitria et al, 2020).…”

Development of Guided Invention Based Learning Tools on Circle Material to Facilitate Mathematical Comprehension Ability of Class VI SD / MI

“…The teacher is not only the deliverer of the material but the teacher can be said to be the designer of learning activities. Fitria (2020) states that most teachers have not developed learning tools that are in accordance with the 2013 curriculum and students need. Learning devices that are made are only limited to the administrative requirements provided by the teacher without paying attention to the goals to be achieved (Atika, 2020).…”
