Desain E-LKPD Berbasis Concept Image Siswa pada Materi Barisan dan Deret

Abstract

This study aims to develop a concept image-based E-LKPD on sequences and series using the ADDIE model.
This development research was carried out up to the Development stage, which includes Analysis, Design,
and Development. In the analysis stage, learning needs were identified through concept image tests,
interviews, and documentation studies. The results of the analysis showed that students still had difficulty
in understanding the concepts of sequences and series in depth, differentiating the concepts of sequences and
series, and connecting various mathematical representations. Based on these needs, an E-LKPD was designed
that included problem-oriented activities, pattern exploration, concept construction, concept reflection, and
contextual application. In the development stage, the E-LKPD prototype was compiled and validated by
material experts and media experts to assess the feasibility of content, presentation, language, and
appearance. The validation results showed that the developed E-LKPD met the valid criteria and was suitable
for use as a supporting teaching material for mathematics learning. The concept image-based E-LKPD is
expected to help students build a better conceptual understanding of sequences and series through the
integration of visual, verbal, numeric, and symbolic representations.
