The teacher's use of student performance data for vocabulary instruction underscores the importance of which reading assessment approach?

The selection of using results from reading assessments to guide instructional decision making highlights the critical role that data plays in shaping effective vocabulary instruction. This approach emphasizes the need for teachers to analyze performance data to identify specific areas where students may be struggling or excelling in their vocabulary skills. By doing so, educators can tailor their instruction to meet the distinct needs of their students and adjust their teaching strategies accordingly.

When teachers utilize data from assessments, they can make informed decisions about which vocabulary words or concepts require more focus in their lessons. This targeted approach not only maximizes the effectiveness of instruction but also ensures that interventions are aligned with students' actual needs, promoting better academic outcomes. Thus, this method aligns with best practices in education, where data-driven instruction supports differentiated learning and engages students more effectively.
