VALIDITAS LEMBAR KERJA PESERTA DIDIK MENGGUNAKAN MODEL DISCOVERY-KUMON UNTUK MELATIH KEMAMPUAN BERPIKIR KRITIS PADA MATERI SPLDV KELAS VIII SMP
This study aims to describe the development of LKPD using the Discovery-Kumon model to train critical thinking skills with valid criteria. The type of research used is Research and Development using the 4D research model, namely (Define, Design, Development, Disseminate). This research was only conducted up to the development stage, namely only up to the validation stage by experts without field testing. The research instrument used was a validation sheet for material experts, media experts, and linguists. Based on the validation of material, media, and language by experts, LKPD using the Discovery-Kumon model is categorized as valid. So it can be concluded that LKPD uses the Discovery-Kumon model to train critical thinking skills on the SPLDV material developed which is declared valid and fit for use.
