Which principle emphasizes the importance of using evidence-based instructional strategies?

Possessing a repertoire of instructional strategies is essential because it underscores the need for educators to utilize a variety of evidence-based approaches tailored to meet diverse student needs, especially in special education settings. Evidence-based instructional strategies are those that have been proven effective through rigorous research and can lead to improved student outcomes. By having a broad range of these strategies at their disposal, educators can better address individual learning styles, challenges, and preferences, ultimately enhancing the educational experience for students with mild interventions.

In contrast to the other choices, while developing relationships with families, advocating for better resources, and maintaining high professional integrity are all important aspects of teaching, they do not specifically emphasize the use of evidence-based practices. The focus of possessing a repertoire of instructional strategies is squarely on the application of research-supported methods in the classroom, ensuring that teaching is both effective and responsive to the needs of students with varying abilities.
