How to Improve Interactivity in Online Education

After the online learning model of Khan Academy gained widespread recognition, online education has rapidly emerged like bamboo shoots after a spring rain. However, behind this rise, online educators have to face one problem after another. In online education, how can students be more focused on learning online? Online education delivers lessons through recorded or live online videos. Its primary medium is video, because compared to text and audio, video is diverse, three-dimensional, and the closest experience to offline classroom learning.

However, problems arise. How to address video security issues? How to solve interactivity problems during learning? How to prevent students from getting distracted and doing other things while studying... Without strong video security measures, issues like hotlinking, unauthorized downloading, and unauthorized streaming of videos can cause immeasurable economic losses for online educators. Relying solely on lecture videos or screen-recorded course videos as a single learning method can impart knowledge and experience, but it lacks interaction with teachers and classmates and provides no teaching feedback. In effect, it resembles "self-study," making it difficult to guarantee learning outcomes. Can online education ensure that students study seriously instead of playing games? It seems no one can guarantee this. Faced with the temptations of the internet, I believe most online learners find it hard to resist online distractions. Therefore, online educators urgently need a powerful video platform—one that provides robust security, strong video features, and solid video technical support for online education. To address these issues in online education, POLYV's cloud video platform offers powerful video hosting services for online educators. Regarding video security, POLYV has implemented comprehensive anti-piracy measures, from video file encryption to screen recording prevention. POLYV has independently developed a video encryption technology based on keyframe disordering, combined with OVP video hotlink protection technology, to ensure the security of video files. Additionally, POLYV uses technologies such as video watermarking, video scrolling text, and quiz player to increase the cost and difficulty of video piracy for pirates. When it comes to classroom interaction and preventing students from zoning out, we recall how teachers in schools address this issue. Asking questions in class! This is undoubtedly a childhood shadow for many, yet this method effectively enhances classroom interactivity and significantly reduces students' tendency to daydream in class. Based on the offline learning method of asking questions in class, POLYV has developed a new video technology that incorporates a questioning segment into the learning process. Online learners must correctly answer questions that pop up on the screen (defined freely by the teacher, one or several) to proceed with the next step of learning. If they answer incorrectly, the video will jump back to a specific point (defined freely by the teacher) for review, achieving classroom interaction while ensuring students study online attentively. Online education still has a long way to go. POLYV spares no effort in providing safe and reliable video services for online education, safeguarding its long-term development.
