Correct Response: C. Option C is correct because an important component of evidence-based fluency instruction is providing students with explicit models of prosodic reading—reading that has the phrasing, pacing, and expression of spoken language. Echo reading is a strategy in which a fluent reader reads aloud a small portion of a shared text, and a student or students immediately reread the same short passage, echoing the model's performance. In Option C, the volunteer would provide an individual student with an explicit model of prosodic reading followed by scaffolded practice through the use of echo reading. Options A, B, and D are incorrect because having the volunteers listen to the students engage in a "cold" reading of a text (A), time the students' reading rate (B), or monitor the students' on-task behavior (D) would not provide the students with modeling of or instruction in prosodic reading.
