E-LKPD Berbasis Problem Based Learning Disertai Kuis Interaktif Matematika untuk Meningkatkan Kemampuan Berpikir Kritis

Abstract

This development research aims to determine the process of developing E-LKPD (Electronic Student Worksheets) based on Problem Based Learning accompanied by interactive math quizzes to improve students' critical thinking skills that are valid, feasible and effective. The results of observations of mathematics learning in class X MIPA at SMAN 1 Malang show that there are no teaching materials that use interactive live worksheets. Critical thinking is the ability to solve problems which include steps to identify, organize and implement strategies and techniques, evaluate and draw conclusions. This type of research is the development of the ADDIE model (Analysis, Design, Development, Implementation, Evaluations). The research results from the validity test have an average of 3.33 by design experts with a very valid category, 3.27 by mathematics learning experts with a very valid category and 3.11 by material experts with a valid category. The results of the feasibility test on a small scale obtained a percentage of 81% with a very feasible category and 86% on a large scale trial with a very feasible category. The results of the effectiveness test obtained a percentage of completeness 100% in small-scale trials and 86% in large-scale trials so that both obtained effective categories. The conclusion of this study is that E-LKPD based on Problem Based Learning with interactive math quizzes is valid, feasible and effective and can improve students' critical thinking skills.

Development of Scientific-Based Thematic Worksheets to Improve Cognitive and Language Abilities of Children Aged 5-6 Years

“…The findings of the author's research (2022) are also supported by the following previous studies, which demonstrate the effectiveness of thematic LKPD development: Munika et al (2021), Muchlis (2021), Munawaroh (2022), Sagita & Erianjoni (2021), Puspita (2022), Fatmawanti & Istihapsari (2022), Geacelyn et al (2021), Temiyati & Nuryadi (2022), Nata & Manuaba (2022), Pranata (2021), Hatimah et al (2022), Nurhayati & Sylvia (2021), Najmi (2021), Sukmawati et al (2021), Dilla & Sylvia (2021), Utomo (2022), Puri (2022), andPrabandari et al (2022).…”

Effect of Using Electronic Student Worksheets in Mathematics Learning on the Reasoning Ability of 8th-Grade Junior High School Students

“…Several previous studies have stated that the use of electronic student worksheets can also affect other mathematical abilities in students. This can be seen in the research findings of Munika, Marsitin, & Sesanti (2021), which prove that the use of electronic student worksheets with a problem-based learning approach can enhance critical thinking skills, as evidenced by the comparison of pre-test completeness percentage of 81% and post-test completeness percentage of 86%. In another study conducted by Bombang, Fayeldi, & Pranyata (2022), the use of Electronic Student Worksheets was found to be effective in improving students' mathematical problem-solving abilities.…”

Development of Electronic Student Worksheets (E-LKPD) Based on Problem Based Learning as an Effort to Improve Critical Thinking of Grade VIII Middle School Students on Respiratory System Material

“…The problem based learning model is able to have a good influence on oral, written communication and critical thinking (Aini et al, 2019). This is reinforced by the statement by Elfina & Sylvia (2020), Fitriyah &Ghofur (2021), andMunika et al (2021) that if the results of the effectiveness test obtain a good percentage in the small scale test and large scale test then it can be categorized as effective. This is because the E-LKPD is prepared systematically and involves critical thinking indicators.…”
