Whether in a classroom or online, managing a successful course requires two-way communication between the teacher and students. Constantly monitoring a course's logs and grades gives you an early indication that a class may need a midcourse correction. You can use questions, surveys, and chats to discover specific problems and challenges the students are facing. After bringing the course back on track, custom grading scales, extra credit, and curves can help you to equalize the grades. When teaching online, make a habit of often checking the logs and grades.
