CompendiumLD is a tool for visualizing the process and products of learning design. It provides a design environment for creating learning designs using stencils, nodes, and layouts to support the design process. Designs can be evaluated both quantitatively and qualitatively by gathering resources, tools, and data. Completed designs can then be assembled, run, and shared either as editable data or exported as HTML. Future development ideas include improved sharing and editing of designs across different platforms and formats.
