Pengembangan E-LKPD Interaktif Segi Banyak Beraturan Dan Tidak Beraturan Berbasis Liveworksheets Terhadap Hasil Belajar Peserta Didik Kelas IV Sekolah Dasar

Abstract

This study aims to develop interactive E-LKPD in terms of many regular and irregular liveworksheets based on the learning outcomes of students in grade IV elementary schools that are valid, practical, and effective. This research is a type of Research & Development research. The development model used is the development model according to Tjeer Plomp. The procedure for the Plomp development research model consists of three phases, namely preliminary research, prototyping stage, and assessment stage. This research was conducted on fourth grade students of SDN 07 Binuang Kampung Dalam. The type of data used in this research is primary data. The research instrument used test and non-test instruments.

The results showed that: (1) the results of the interactive E-LKPD validation test as a whole by three validators, namely the material, media and language aspects obtained an average value of 87.68% in the very valid category, (2) the results of the E- practicality test. Interactive LKPD by the teacher and students obtained a value of 95.83% and 93.41% respectively in the very practical category, (3) the results of the effectiveness test with the calculation of the t test, namely t count> t table or 5.94361> 2.262, and obtaining an average pretest score of 68.3 and obtaining an average posttest score of 89.2. Based on the results of the research that has been done, it can be concluded that the interactive E-LKPD in terms of many regular and irregular liveworksheets based on liveworksheets is very valid, very practical, and effective to use in mathematics learning in grade IV SD.
