Abstract

This study aims to determine the validation and reliability of the blended learning instrument test using the react strategy with the sscs model on critical thinking skills. The subjects of this study were 4 experts. The instrument used is RPP, LKPD, about critical thinking skills. The results of the expert test using the Aiken^s Validation formula concluded that the RPP was 0.938, LKPD 0.947, critical thinking questions were 0.898, while reliability using Anava Hoyt showed RPP 0.713, LKPD 0.725, critical thinking questions 0.726 with high reliability. This shows that the results of the expert^s assessment of the RPP, LKPD, and critical thinking instruments are feasible to use.
