What aspect should be emphasized in effective professional development?

Emphasizing that professional development should be modeled by experienced key teachers highlights the importance of practical, real-world application in training educators. Experienced teachers can provide valuable insights, share proven strategies, and demonstrate effective teaching practices that are grounded in actual classroom experiences. This kind of modeling makes the professional development relevant and relatable for other educators, as they can see directly how the strategies can be applied in their own teaching contexts. Furthermore, when professional development is facilitated by skilled peers, it can foster a culture of collaboration and trust among staff, encouraging a shared commitment to improving student outcomes and teaching effectiveness.

In contrast, options that suggest a focus on cost or isolation from daily practice overlook the need for professional development to be practical and integrated into the educators' routines. A focus solely on digital resources may limit the scope of professional development, while isolating it from daily practice can render it ineffective, as educators might struggle to implement new strategies that are not connected to their actual teaching experiences.
