Landforms are physical features of the Earth's surface, such as mountains, valleys, plains, rivers, inlets, deltas, basins, and so on. Most are naturally occurring, but some constructed features such as dams and canals may also be discussed with landforms. For students with little or no usable vision, understanding the sizes and relationships of these features presents challenges.
This survey asks whether instruction in understanding landforms is needed by students who are blind or severely visually impaired and, if so, whether existing APH materials are useful for this purpose. Your responses are valuable even if you do not use the materials in question.
