This WikiBook is part of the public Last Language Textbook campaign to build completely free multimedia language textbooks that are designed for re-use and customization. To accomplish this we are combining the WikiBook book building tools with the Wikiotics tools for building interactive language lessons. All material on both platforms is freely available under the same CC-BY-SA license so material can be straightforwardly moved and combined.
While the structure of this particular book is organized to support the dual-language instruction program at PS 9 in Brooklyn, New York, the curriculum is general enough to suit most any self-directed language student and general purpose Spanish language instruction contributions are welcome. Activity on this project is primarily from the Wikiotics Foundation and teachers of PS 9 but is open to all.
