What main issue is causing Mrs. Cabbage frustration in her efforts to create a collaborative environment?

Mrs. Cabbage's frustration in her efforts to create a collaborative environment is primarily due to insufficient parent participation. For effective collaboration, especially in educational settings, active involvement from parents is vital. Their engagement can facilitate communication between the school and home, support students’ learning experiences, and contribute to a shared sense of community. When parents are not sufficiently involved, it can create barriers to creating a supportive network that enhances collaboration among teachers, students, and families. This lack of participation can lead to missed opportunities for diverse perspectives and resources that enrich the collaborative process.
