Suitable mainly for high school, Hippocampus is a digital library of multimedia modules for instruction in popular courses such as Calculus, U.S. Government, AP Biology,
Environmental Science, Pscyhology or Statistics. Users may browse the content in two ways, either through the Course or Textbook interfaces.
Modules are browsable either through alphabetical or sequenetial topic listing or through a course view which is organized into main units, organized into lessons.
An especially useful feature is the “textbook” tab which presents content in correlation with popular subject textbooks. There’s also a detailed index of page numbers and topic coverage by text.
