What is a significant benefit of using live instructors in distance learning?

Using live instructors in distance learning offers the significant benefit of allowing for immediate feedback and interaction. This aspect enhances the learning experience by enabling students to ask questions in real time, clarify doubts, and engage actively with the material being taught. Interactive sessions can lead to deeper understanding as instructors can adjust their teaching methods based on instant feedback from learners. This dynamic interaction mimics a traditional classroom environment and helps maintain student engagement, which is critical in an online learning setting.

In contrast, other options do not capture the core advantages provided by live instruction. For instance, eliminating the need for homework or asserting that live instruction always results in lower costs does overlook the realities of educational assessments and budgeting, respectively. Similarly, while it is possible for some courses to not require registration, this is not inherently a feature of live instruction.
