Teachers' collaboration supports expanding their expertise in several ways:
1. Sharing ideas and experiences with other teachers exposes one to new perspectives and approaches to teaching. This prevents sticking to familiar routines and encourages continuous learning.
2. Discussing teaching practices with colleagues allows for reflection on and improvement of one's own methods. Feedback and fresh viewpoints can help one strengthen weaker areas.
3. Collaborating on projects, lessons or problem-solving provides opportunities to learn from others' strengths and expertise. Taking on new roles alongside more experienced teachers facilitates skills growth.
4. Participating in a community of practice promotes experimentation and a culture of lifelong learning. Networking internally and externally expands sources for developing expertise.
