The Development of Fishbone Learning Media on the Theme of Animal and Human Movement Organs with a Problem-Based Learning Model to Improve Critical Thinking Skills of Elementary School Students

Abstract

This study aims to analyze the effect of fishbone learning media on the theme of animal and human movement organs with a problem-based learning model in improving critical thinking skills of elementary school students. This development research used the Research and Development (R&D) method. The subjects of a small-scale test were conducted at Asem Elementary School with 15 students in class V, and a large-scale test was conducted at SDN 1 Sidanglaut with 30 students in class V. The average media feasibility value is 85.9, which is a very valid category. The average validity value of a material is 87.5, which is a very valid category. The average validity value of the RPP is 85.1, which is a very valid category. Fishbone diagrams with the theme of animal and human movement organs and problem-based learning models effectively improve students' critical thinking skills both from the results of small-scale and large-scale tests. The small-scale test and T-test result (2-tailed) is 0.000 <0.05, a significant difference between students' pre-test and post-test. Keywords: Learning Media, Fishbone, Critical Thinking
