Development of E-Worksheet To Improve Students’ Mathematical Problem Solving Ability

Abstract

The purpose of this research is to produce learning media in the form of practical and effective student worksheets. In addition, this research is also to improve the mathematical problem solving ability of high school students in class X on the material of a three-variable system of linear equations. The method used is the R&D (Research and Development) method with a 4D model (Define, Design, Development and Disseminate). The validity test was carried out by mathematics teachers, mathematics lecturers, and media expert lecturers. The results showed that the media that had been developed based on the results of the validity test in the aspect of display quality was 94.79% in the very good category, the written text was 93.75% in the very good category, and device engineering 94.79% in the very good category. The developed media was tested practically by 10 respondents. The practicality test showed that the display quality was 99.16% in the very good category, the text results were 99.37% in the very good category, and the results of the device engineering were 100% in the very good category. The results of the students’ mathematical problem solving ability scores ranged from 75 to 100 from the results of answering e-worksheets, so that the average obtained from each student on mathematical problem-solving abilities was in the “high” category and the average percentage obtained was 94.10% in the “very good” category. Based on the results of data acquisition, it shows that the e-worksheet media on the material of a three-variable linear equation system is feasible to be used as a learning resource and can also improve students’ mathematical problem-solving abilities.

Application of Guided Discovery Learning (Gdl) Model in an Effort to Improve Students’ Mathematical Problem Solving Ability

“…Mathematics is one part of the educational curriculum that has an important role in improving human resources in Indonesia. This is in line with the opinion of Kusnandar & Yusuf (2023) which states that mathematics is one of the most important subjects and is always related to everyday life, where every activity carried out by humans is always related to mathematics. Therefore, mathematics is one of the subjects that is considered to play an important role, so the purpose of learning mathematics in schools is to develop mathematical abilities in students.…”

Pengaruh Model Pembelajaran TGT (Teams Games Tournament) Modifikasi Metode Gasing Terhadap Hasil Belajar Matematika Siswa

“…Berdasarkan pengertian tersebut dapat disimpulkan bahwa guru perlu menggunakan model, metode pembelajaran yang efektif, interaktif, dan dapat menarik perhatian siswa untuk belajar khususnya dalam pembelajaran matematika. Hal ini sependapat menurut (Mawaddah & Siswanto, 2022) bahwa kemampuan guru dalam memadukan metode, model, atau strategi ke dalam proses pendidikan untuk mencapai tujuan yang maksimal sangat menentukan keberhasilan siswa dalam belajar matematika. Selain itu, karakteristik penyebab rendahnya hasil belajar matematika siswa ditemukan peneliti di SD Muhammadiyah 06 Medan.…”

Development of LKPD Based on Contextual Teaching and Learning on Square and Rectangular Materials to Improve Learning Outcomes of Grade IV Elementary School Students

“…According to Wijaya et al (2019), 48% of 28 teachers in Indonesia are involved in drill and practice to achieve success in sibling relationships, 31% are involved in drill and practice, and 17% use or develop new specific strategies, this suggests that a teacher is using strategies to support students who are proficient in math (Chin & Fu, 2021). According to Janah (2020), that the ability of teachers to integrate methods, models, or strategies into the educational process to achieve maximum goals greatly determines the success of students in learning mathematics (Mawaddah & Siswanto, 2022). The teacher's ability to integrate Lisa Oktapia, Lailatun Nur Kamalia Siregar methods, models, or strategies into the educational process to achieve maximum goals greatly determines student success in learning mathematics (Shodikin et al, 2022).…”
