Pengembangan Perangkat Pembelajaran Berbasis Model Problem Solving Untuk Meningkatkan Kemampuan Kognitif Pada Materi Gelombang Bunyi Siswa Kelas Viii Smp
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.
