PENGEMBANGAN PERANGKAT PEMBELAJARAN BERBASIS MODEL PROBLEM SOLVING UNTUK MENINGKATKAN KEMAMPUAN KOGNITIF PADA MATERI GELOMBANG BUNYI SISWA KELAS VIII SMP

Abstract

Abstract: The learning device developed is a problem solving model based on sound
wave material for grade VIII SMP students, consisting of a Learning Implementation Plan
(RPP), Student Worksheets (LKPD), and Learning Outcomes Test. The purpose of this
study was to determine the validity of learning tools based on problem solving models on
sound wave materials. This type of research is a Research and Development (R&D) with a
4D model design. The research instrument used was the RPP validation assessment sheet,
LKPD, and the Learning Outcomes Test which were used by the validator to assess
learning tools. Data analysis in this study used descriptive analysis. Based on the results
of the validity data analysis, the average value of the validity of the lesson plan was 3.60
with a very high category, the average validity of LKPD was 3.49 with a very high
category and the Learning Outcomes Test was 3.38 with a very high category, so that the
average -The overall average of learning devices is 3.49 with a very high category. Thus,
learning tools based on the problem solving model are declared valid and suitable for use
in sound wave material in class VIII SMP.
