Step-by-step explanation:
The most effective strategy for using technology to enhance a principal's effectiveness as an instructional leader would likely be option C: regularly participating in online collaboration for school administrators to share best practices and gather input from each other. This strategy allows the principal to connect with other administrators, share ideas, and stay up-to-date on current trends and best practices in education. By collaborating online, the principal can access a wealth of knowledge and expertise from a diverse group of professionals.
