Abstract

This study aims to determine the level of validity, practicality, and effectiveness of the developed product, which is the PBL-based LKPD, to enhance critical thinking skills in the topics of Length and Weight measurement in 3rd-grade elementary school students. The research method used is Research and Development (R&D) with the ADDIE development model (Analysis, Design, Development, Implementation, Evaluation). The validation results of the PBL-based LKPD show high scores in the content aspect (0.9305), language aspect (0.9472), and graphic design aspect (0.9652), indicating that this product is aligned with learning objectives, easy to understand, and has a supporting visual design. The practicality test shows ease of use by teachers (92%) and students (90%) and the ability to motivate students to actively participate. The N-Gain test demonstrates a significant improvement in students' critical thinking skills with a score of 0.743. Overall, this LKPD is valid, practical, and effective in enhancing critical thinking skills, making it an ideal recommendation for mathematics learning in elementary schools.

Abstract

This study aims to develop and test the effectiveness of the Student Worksheet (LKPD) based on Problem Based Learning (PBL) in improving students' collaboration skills in data processing material at SD Negeri 1 Waydadi, Sukarame District, Bandar Lampung City. The study uses the ADDIE development model, which consists of five stages: analysis, design, development, implementation, and evaluation. The developed LKPD was validated by experts in content, language, and graphic design, and then tested in the classroom with 5 students. The effectiveness evaluation was conducted using the N-gain test to measure changes in collaboration skills before and after the implementation of the LKPD. The results show that the PBL-based LKPD is effective in improving students' collaboration skills, with an N-gain value of 81.4%, which falls into the high category. Although there are challenges in the equitable distribution of tasks and communication among group members, overall, this LKPD has proven to be practical and effective for use in learning to enhance students' collaboration skills.

Abstract

This study aims to develop a Problem Based Learning (PBL)-based Student Worksheet (LKPD) that is both valid and practical to enhance the critical thinking skills of fifth-grade elementary school students in the topic of solid geometry. The research employed a Research and Development (R&D) method using the ADDIE development model, which consists of five phases: analysis, design, development, implementation, and evaluation. Validation was conducted by subject matter and language experts, resulting in an average score of 0.858, categorized as highly valid. A practicality test was carried out using questionnaires for students and teachers, showing a practicality level of 92%, classified as highly practical. Student responses indicated that the developed LKPD features an attractive design, is easy to understand, and effectively facilitates critical thinking activities and mathematical problem solving. Therefore, the PBL-based LKPD is deemed feasible for use as an innovative and effective learning medium to support the improvement of mathematics instruction quality in elementary schools.

Abstract

This study was motivated by the low level of critical thinking skills among primary school students in science learning, which requires innovation in teaching materials. The purpose of this study was to develop and test the effectiveness of Student Worksheets based on Problem-Based Learning (PBL) to improve critical thinking skills in the subject of 'Light and Its Properties'. Research and Development (R&D) were conducted using the ADDIE model and a quasi-experimental design. The research subjects consisted of 52 fifth-grade elementary school students, divided into experimental and control groups. The research instruments included essay tests, observation sheets, and assessment rubrics. Expert validation results showed that the Student Worksheet was deemed highly valid in terms of media (4.58), valid in terms of material (4.44), and valid in terms of language (4.46). The effectiveness test results proved that the experimental class experienced a significant increase in all critical thinking indicators (total score of 20.9) compared to the control class (14.1). Statistical tests (p < 0.001) and effect sizes (Cohen's d = 1.65-2.45) confirmed that this improvement was statistically significant and had a large effect. It was concluded that PBL-based Student Worksheets were effective in fostering critical thinking skills in primary school students and were recommended for use in science learning.
