Abstract:
Pteridophyta is a sub-concept on Plant (Plantae) material in the Biology subject for Grade X Senior High School. In this competency, students are expected to apply classification principles to classify plants into divisions based on observations of plant morphology and metagenesis and linking their role in the continuity of life on earth. However, most students still find it difficult to understand the concept. This Pteridophyta is due to the lack of local potential-based references that are directly related to student life, one of which is learning media. Learning media is one of the means to help teachers and students learn concepts in Biology more broadly. This encourages researchers to develop learning media in the form of a booklet on the Plantae material sub-concept of ferns (Pteridophyta). This study aims to describe the validity of the booklet developed on the types of ferns (Pteridophyta) on the riverbanks of the Wisata Alam Sungai Kembang. This research uses RandD method with 4D development model to develop learning media in the form of booklets. The results of the validity test of the developed booklet showed very valid results.
