So how can high-stakes assessments be meaningful to students? For one thing, high-stakes tests shouldn't be so high-stakes. It's inauthentic. They should and still can be a mere snapshot of ability. Additionally, those occasional assessments need to take a back seat to the real learning and achievement going on in every day assessments observed by the teacher.
The key here, however, is to assess everyday. Not in boring, multiple-choice daily quizzes, but in informal, engaging assessments that take more than just a snapshot of a student's knowledge at one moment in time.
But frankly, any assessment that sounds cool can still be made meaningless. It's how the students interact with the test that makes it meaningful. Remember the 4 Cs and ask this: does the assessment allow for:
Creativity Are they students creating or just regurgitating? Are they being given credit for presenting something other than what was described?
Collaboration Have they spent some time working with others to formulate their thoughts, brainstorm, or seek feedback from peers?
Critical Thinking Are the students doing more work than the teacher in seeking out information and problem solving?
Communication Does the assessment emphasize the need to communicate the content well? Is there writing involved as well as other modalities? If asked to teach the content to other students, what methods will the student use to communicate the information and help embed it more deeply?
