Diagnostic Assessment
Diagnostic assessments (also known as pre-
assessments) provide instructors with information
about student's prior knowledge and misconceptions
before beginning a learning activity. They also provide
a baseline for understanding how much learning has
taken place after the learning activity is completed.
Instructors usually build concepts sequentiallythroughout a course.
