PENGEMBANGAN LEMBAR KERJA PESERTA DIDIK (LKPD) BERBASIS PROBLEM BASED LEARNING (PBL) PADA MATA PELAJARAN IPA KELAS V SD ADVENT 6 AIR BERSIH

Abstrak

This study aims to develop Problem Based Learning (PBL) worksheets on heat
and its transfer that are valid and practical. This study uses the research and
development (R & D) method, this model consists of 5 stages, namely: Analysis
(Analysis Stage), Design (Planning Stage), Development (Development Stage),
Implementation (Implementation Stage), Evaluation (Assessment Stage). The
product developed is in the form of Problem Based Learning (PBL) based
worksheets which are tested through validity tests and practicality tests. The
subjects in the study were 20 students in class V SD Advent 6 Air Bersih T.P
2022/2023. The instruments used in data collection were validation sheets to
determine the validity level of the developed LKPD and those obtained from a
team of experts, and a teacher questionnaire to determine the practicality of the
developed LKPD. The results showed that the LKPD based on Problem Based
Learning (PBL) on Heat and Transfer Material that the researchers developed
had a very valid level of validity by a team of design experts, namely 85.71% and
a team of very valid material experts, namely 91.25% and a team of homeroom
teachers for class V very Practical, namely 94.64% of the results of the 3
validators are included in the very high category so that the Problem Based
Learning (PBL) based LKPD is feasible to use because it meets very valid and
very practical criteria.
