Development of PBL-Based Liveworksheet E-LKPD on Circle Topics for Eighth Grade to Improve Mathematical Literacy Skills

Abstract

This research aims to develop an E-LKPD Liveworksheet based on Problem Based Learning (PBL) for circle material in 8th grade, to enhance students' mathematical literacy abilities. This is motivated by the low mathematical literacy of Indonesian students based on PISA results and the limited utilization of technology in learning. This Research and Development (R&D) study adopts the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation), focusing solely on the development stage through a small-scale trial involving 2 teachers and 6 students. The research results indicate that the developed E-LKPD Liveworksheet is highly valid and practical. The product's validity obtained a percentage of 93.12% from material experts (very valid) and 92.04% from media experts (very valid). Meanwhile, the practicality of the product achieved a percentage of 95.65% from teacher trials (very practical) and 83.77% from student trials (very practical), with an overall recapitulation of 87.81% (very practical). Thus, this PBL-based E-LKPD Liveworksheet is highly practical for use in mathematics learning
