- Try to keep it under ten minutes, ideally around five minutes, and focus on one topic.
- The more granular the video cuts, the more opportunities there will be to incorporate different exercises, providing greater flexibility for adjustments or replacements with better videos in the future.
- Course design should progress from simple to complex, with clear explanations, allowing students to learn at their own pace based on their abilities.
- Respect, enthusiasm, and companionship should guide your mindset during recording.
- When teaching, think about how to spark interest in learning to enhance motivation.
- Share your knowledge rather than adopting a 'teaching' tone. Remind students what (what) they will learn, why they need to take this lesson (why), and where it can be applied (where).
- Start from life experiences and then introduce concepts.
- Each definition or concept should be explained with 2-3 examples.
Based on a big data analysis conducted by MIT in 2014 of 100,000 students on MOOCs (Massive Open Online Courses), which involved viewing 6.9 million online course videos, a research report was published revealing the following five very important findings.
- Data analysis shows that static PPT presentations are a killer of focus. More visual effects (such as an image or a video) are needed to capture and maintain student attention.
- Proven fast-talking professors attract students more than slow-paced educators. Research shows that professors speaking at a rate of 254 words per minute achieve the highest student engagement.
- Long online videos tend to have lower student engagement; shorter videos are more effective at maintaining attention. Students often choose to stop watching after the first 6 minutes (the golden 6 minutes).
- When fast-talking professors are key, long pauses can actually help students better understand complex charts, which is an important finding.
- Videos specially designed for online audiences perform much better than existing videos, as these designed videos are simply cut into segments for presentation.
- Maintain enthusiasm, speak at a slightly faster pace, and keep your tone slightly higher; avoid speaking solely from the throat.
- Reduce filler words and incorporate intonation during key points.
- Keep smiling; changes in facial muscles will be reflected in your voice.
- Avoid using terms like difficult, simple, or things that will be taught in the future. Instead, use terms like 'challenging' or 'more exciting.'
- Find ways to attract students.
