Discussion forums are a common form of interaction in online courses. You can ask questions, share ideas, and learn from other students. These forums create a sense of community and allow you to gain different perspectives. For example, in a business course, you can discuss case studies with classmates from different backgrounds, enriching your understanding of business strategies and problem-solving approaches.

Many online courses incorporate quizzes, assignments, and projects. These interactive elements help you apply what you've learned and receive feedback. You might have to complete coding projects in a programming course or write essays in a literature course. This hands-on approach helps you retain information better than passive learning. You can also work in groups on collaborative projects, developing teamwork and communication skills.

Live sessions with instructors are becoming more popular. These can be webinars, Q&A sessions, or virtual classrooms. You can get real-time answers to your questions and engage directly with the instructor. Some platforms even offer one-on-one mentoring. In a design course, you could get personalized feedback on your work during a live session, helping you improve your skills faster.
