Which teaching strategy splits some of the responsibilities among more than one instructor?

The teaching strategy that involves sharing responsibilities among more than one instructor is identified as using multiple instructors. This approach allows for a variety of teaching styles and expertise to be incorporated into the learning experience, which can enhance the quality of instruction. By having more than one instructor, each instructor can focus on different aspects of the material, provide diverse perspectives, and facilitate different types of interactions, which helps cater to the diverse learning needs of students. This collaboration can lead to a richer educational experience, as students benefit from the strengths and insights of multiple instructors, ultimately leading to better engagement and understanding of the subject matter.
