Efektivitas Model Discovery Learning Berbantuan Media Mibolokus Terhadap Pemahaman Konsep IPAS SD

A learning process that is monotonous and always centered on the teacher can cause students' low understanding of concepts. This can be proven by the reality found at SD 4 Honggosoco. Based on the initial concept understanding test carried out by 20 class V students, it was found that all students' scores were still below the KKTP with an average class score of 20.05. The aim of this research is to find out whether the Discovery Learning model assisted by Mibolokus media has an effect on the results of students' understanding of concepts at SD 4 Honggosoco in science material. This research uses a quantitative type of research. The research design used was a pre-experiment design with one group pretest posttest type. The subjects of this research were all fifth-grade students at SD 4 Honggosoco with a sampling technique using nonprobability sampling, purposive sampling type.
