Which characteristic is essential for effective professional development?

Research-based practices are essential for effective professional development because they ensure that the strategies and methods being implemented are supported by empirical evidence and proven to be effective in enhancing teaching and learning. When professional development is grounded in research, educators are more likely to adopt practices that can lead to significant improvements in instruction and student outcomes.

Using research-based practices also fosters a culture of continuous improvement and encourages educators to reflect on their teaching methods. This is particularly important in a field that is constantly evolving, as it equips educators with the tools and knowledge to adapt to new challenges.

In contrast, one-time workshops tend to lack continuity and follow-up, which can diminish their impact on professional growth. While convenient online courses can be beneficial, they do not always guarantee that the content is grounded in current research or that it addresses the unique needs of educators. Isolated instruction can lead to gaps in knowledge and a lack of collaboration, as effective professional development is often most impactful when it promotes interaction among educators and shared learning experiences.
