Salsa is a Web application for authoring higher education syllabi called SALSAs (Styled & Accessible Learning Service Agreements). SALSAs promote learner-centric and accessible formatting, well-defined learning outcomes/objectives, and inclusion of required policies: accommodations for students with disabilities, academic honesty, course evaluations, etc. Salsa generates a unique and random hyperlink for you. Use the hyperlink to return and edit your SALSA, or publish your SALSA to generate a new hyperlink to a "read-only" copy of your SALSA in PDF or HTML format. No email address or signup is required.
