Abstract

The goal of this research is to create eLKPD that utilizes ProblemBased Learning (PBL) combined with STEM, focusing on electrolyte and nonelectrolyte solutions, with the intention of enhancing critical thinking abilities in students. Additionally, the study seeks to assess the practicality of the eLKPD that incorporates PBL and STEM, based on evaluations from experts in content and media, along with feedback from teachers and students regarding the developed eLKPD. The research follows the Lee & Owens (2004) model, which consists of five phases: analysis, design, development, implementation, and evaluation. The study involved a oneonone trial with 3 students and a small group trial with 10 students at SMAN 2 Muaro Jambi. Qualitative and quantitative analysis methods were employed for data examination. Findings indicated that the created eLKPD, based on PBL integrated with STEM, was deemed both feasible and valid, scoring an average of 4. 75 for material and media validation, and 4. 6 overall. An average score of 4. 66 was recorded for teacher assessments. In the oneonone trial, participants achieved a score of 29, translating to a percentage of 96. 66%. For the small group trial, the total score was 462, with a percentage of 92. 4%. Furthermore, the evaluation results of students' critical thinking showed an average score of 79. 76, with a completion rate of 77%. As a result of these findings, the eLKPD created was confirmed to be valid and practical for educational purposes, receiving positive feedback from students

Abstract

This study aims to develop a guided inquiry-based buffer solution e-LKPD to improve students' critical thinking skills. e-LKPD is designed to be more interesting, interactive and practical by utilizing digital technology in learning. The development model used is the Lee & Owens development model, with 5 stages: analysis, design, development, implementation, and evaluation. The research instruments include teacher interview sheets, student needs questionnaires, material expert validation questionnaires, media expert validation questionnaires, teacher assessments and student response questionnaires. The trial was conducted on 10 grade XI phase F students. The results of the e-LKPD development research were declared valid and suitable for use in learning. The assessment by the material validator obtained a score of 0.83 in the feasible category. The media validator gave a score of 0.87 in the feasible category. The teacher's assessment showed a score of 4.3 included in the very feasible category. The trial to students showed a level of effectiveness with an N-gain value of 0.61 in the moderate category. Students gave a positive response with a value of 88% in the very good category. This guided inquiry-based e-LKPD has been proven to be valid, feasible and effective in improving students' critical thinking skills.
