Live Interactive Education

The Live Interactive Education solution enables customers to implement online examination, education video on demand (VoD), interactive live teaching, and class sign-in on HUAWEI CLOUD.
Solution Advantages
  • Multiple Interaction Methods

    Teachers and students can communicate with one another using audio, videos, and text messages. Teachers can interact with students by writing content on whiteboards or annotating courseware documents in real time. Students can also answer or raise questions in real time.

  • Real-time Content Sharing

    Teachers and students can watch the same content and annotations on whiteboards at the same time using their own PCs, mobile phones, and tablets. Teachers can also control the sharing of auto and video files with students.

  • In-class Management

    Teachers and students can use public cloud services for online testing, test result analysis, revealing answers, and providing further information. In addition, teachers can use functions such as roll call, screen lock, attendance statistics, and desktop monitoring to enhance teaching efficiency.

  • Flexible Class Modes

    Interactive class: Applicable to a class with fewer than 100 students, group class, and family teaching mode (one-to-one or one-to-many). Live broadcasting class: Applicable to a class with thousands or tens of thousands of students, network live broadcasting, and vocational training. With an installation-free client, this solution features high mobility, low cost, and strong interactivity, and provides various teaching functions and multi-terminal courses.

Business Challenges
  • Poor Interaction

    Teachers and students do not have timely and effective communication and interaction, and the interaction modes are too simple.

  • Lack of Self-discipline of Students

    Due to lack of supervision, students' self-discipline and concentration problems cannot be resolved.

  • Singular, Boring Teaching Style

    Teaching methods are simple. VoD learning is mainly used.

  • Low Class Loyalty

    Simple interactions and teaching modes cause low class loyalty.
