Pathways are a series of tutorials which follow a specific scope and sequence which loosely align to the Common Core Standards (science would be NRC and 2061). They include both "many ways to learn" as well as a quiz series. Sophia's "Many Ways to Learn" can be seen at the bottom of the screen in a tutorial and allows a learner to choose a different teaching style covering the identical content.
You can easily assign them to your class through a tutorial giving them directions and a link to the pathway by inserting text in the content area. One tutorial below, Quarter 1 Task, illustrates how this could be done.
Other tutorials will explain what a Learning Pathway is and how to use Sophia's MANY WAYS.
