I choose this article because it breaks down fully the difference between formative and summative assessment, which are the two main types of assessment.
This article talks about KWLs, a way to measure student learning quickly and efficiently. The letters KWL stand for "what we know", what we want to know", and "what we learned". I choose this article as a resource because it helps instructors gage a students prior knowledge and even gives you a timeline of what using the KWL assessment should look like.
