Final answer:
Center-based teachers are qualified and specialized teachers with full teaching credentials who work in schools or programs. They are highly trained education experts who have obtained a degree in teaching and play a crucial role in student success.
Step-by-step explanation:
Center-based teachers are teachers with full teaching credentials who work in schools or programs. They are highly trained education experts who have obtained a degree in teaching, typically spending four years earning their credentials. These teachers have the expertise and knowledge necessary to effectively educate students in a classroom setting.
The importance of having qualified teachers is highlighted by the fact that teacher effectiveness is crucial for student success. Studies have shown that students taught by qualified and specialized teachers perform better academically. In contrast, when teachers are not specialized in their subject matter, students may face challenges in their learning.
Providing students with highly qualified and specialized teachers is a priority in education systems around the world. For example, in countries like Singapore, a significantly higher percentage of math teachers major or minor in math compared to the United States. This emphasis on teacher expertise contributes to better outcomes for students.
