Validity of BRADeR Learning Model Development: An Innovative Learning Model to Improve Science Literacy Skills for Junior High School Students

Abstract

The results of the preliminary study show that the scientific literacy ability in 4 SMP Negeri Pematangsiantar is still relatively low. Since science study habits are still traditional and minimize the significance of being able to read science as a competency that students must acquire, there is a tendency for the learning process to not aid students in developing their scientific literacy skills. Due to this, the BRADeR learning model was developed using innovation, taking into account the benefits and drawbacks of the inquiry and SETS models as well as supporting theoretical and empirical research. This study serves to determine the validity of the BRADeR learning model that has been developed. The method of collecting validity data uses the focus group discussion (FGD) method. The validity of the BRADeR learning model was assessed based on content validity and construct validity. The BRADeR learning model was established and is in the very valid category, according to the validity results from experts in the field of science education (IPA). The BRADeR learning paradigm can be used to enhance high school students' science literacy abilities.
