Communication is something we can't neglect. In a face-to-face course, many questions are answered instantly. But online, that's not the case. Therefore, we must be very clear with instructions, explain how to communicate with us, and always respond courteously. Good communication avoids confusion and makes students feel supported, even if we're remote.
If we want our students to have a good online experience, we must support them not only with content, but also by helping them develop reading, writing, participation, and collaboration skills. And all of this must be accompanied by close and effective communication.
