  -      Learning data is generated when students interact with different learning
  -      tools. This data can be combined with student record and other data
  -      points to support student success research. This data can be used by
  -      faculty for proactive intervention with a student or this can be used
  -      to infer how people learn and thus can help in further improving the
  -      learning process. The instructors can also see which behaviors and
  +      Learning data or "learning analytics" is generated when students interact
  +      with online learning tools. These data can be combined with student
  +      record and other data points to support student success. These data can
  +      be used by faculty for proactive intervention with a student, or
  +      to infer how people use the tool and thus can help to improve the
