Abstract

This research was motivated by the results of observations and interviews conducted at SDN Klanderan, which showed that science learning was related to the learning outcomes of the shapes and types of plant leaf bones in class IV. The problems found are 1) students' lack of understanding regarding the material, shapes and types of plant leaf bones 2) students' conditions that are not conducive to learning 3) lack of teacher creativity in delivering learning 4) unavailability of learning media to support student learning 5) results Student learning regarding the shape and types of plant leaf bones is not optimal. The aim of this research is to determine the validity, practicality and effectiveness of the Daun Daun (JEDA) media development. This research uses the RnD (Research and Development) method.
