Assessment: Does the Task Truly Measure What Was Intended?
During a recent NCTM regional conference, a speaker addressed the significance of performance assessment in the mathematics classroom. Afterward, a mathematics teacher posed a question to the speaker: “I agree with you that performance assessment is very important in the classroom, and your sample tasks are very interesting. However, as a classroom teacher, how can I design these kinds of interesting tasks or modify existing tasks to ensure that they accurately measure my own students' performance throughout the year?” Although only one teacher voiced this concern during the session, many other teachers may have similar concerns. The purpose of this article is to share a few of our experiences in developing performance-assessment tasks. We hope that the examples will be helpful to teachers in designing their own performance tasks to measure students' higher-level thinking and reasoning skills in the classroom.
