Which of the following reflects a teacher’s commitment to continual learning?

Choosing professional development courses reflects a teacher's commitment to continual learning because these courses are designed specifically to enhance educators' skills and knowledge. They provide opportunities for teachers to explore new teaching methods, research-based practices, and developments in educational technology or pedagogy. Engaging in these courses demonstrates an active effort to improve one’s teaching capabilities and to stay current with the evolving landscape of education.

A lengthy teaching resume may indicate experience, which is valuable, but it does not directly signal a commitment to continual learning. A comprehensive rating system typically measures performance rather than personal growth or pursuit of knowledge. Participation in teacher unions can be beneficial for advocacy and support, but it does not necessarily reflect a focus on ongoing personal or professional development in teaching practices.
