Didacticism is a philosophy that emphasizes instructional and informative qualities in literature, art, and design. In art, design, architecture, and landscape, didacticism is an emerging conceptual approach that is driven by the urgent need to explain. When applied to ecological questions, didacticism in art, design, architecture and landscape attempts to persuade the viewer of environmental priorities; thus, constituting an entirely new form of explanatory discourse that presents, what can be called "eco-lessons". This concept can be defined as "ecological didacticism".
