Science literacy and communication skills are needed by elementary school students in the 21st century. Scientific literacy is one of the important indicators in assessing students’ readiness to face the complex challenges of modern life. This literacy includes an understanding of scientific principles, critical thinking skills, and decision-making skills based on scientific evidence. On the other hand, scientific communication skills are also very necessary so that students are able to convey scientific ideas clearly and logically, both verbally and in writing. This study aims to analyze how science literacy and communication skills can be improved the development of read, explore, and application (REA) learning model based on ethnoscience. This study aims to increase science literacy and communication skills through an ethnoscience-based Read, Explore, Application (REA) model via a quantitative experimental design with posttest groups, which are divided into 2 groups (experimental group (N=57) and control group (N=57)). The sample included elementary school students from Lamongan Regency who were selected through purposive sampling. Two groups are formed: the experimental group using the REA model and the control group with conventional methods. The data were analyzed via SPSS 26, which includes sample characteristics, descriptive statistics, normality tests, homogeneity tests, and Mann-Whitney U tests. This research revealed that there was a significant difference in scientific literacy and communication skills between the experimental group and the control group, with a Sig value (P value) < 0.05 specifically, for science literacy skills, the Sig value was 0.000 < 0.05, and for communication skills, the Sig value was also 0.000 < 0.05. The development of the Read, Explore, and Application (REA) learning model based on ethnoscience has been proven to improve the scientific literacy and communication skills of elementary school students.
