In this WeChat salon on Thursday, Wang Dandan, deputy general manager of Netease Cloud Communications and Video, shared with us the different stages of online education that require artificial intelligence. The following is the original text, slightly cut.
Nowadays, artificial intelligence has become a hot news topic in the world. Last year, AlphaGo won a 4:1 victory over the top player Li Shishi, making artificial intelligence once again attract the attention of the world. At the beginning of this year, AlphaGo became the mysterious Master, and on the Internet faced professional players who won a 60-game winning streak. Some even assert that the arrival of artificial intelligence will make half of human work disappear within ten years.

So what exactly is artificial intelligence? Probably it can be divided into several parts:
The first is perception, which means that the machine is aware of interactive content including visual, voice, and language.
Then the decision is to make some predictions and make some judgments. These are the decision-making levels.
If you want to complete a complete system, like a robot or autopilot, you will need the final step - feedback.
To give a practical example: a real-time Chinese-English intelligent translation system, perception is to recognize the voice input by the user as text; decision-making, corresponding to the process of translating Chinese text into English text; feedback, corresponding to the text after translation The process of playing the translated statement to the user to the user, even using speech synthesis technology. In this system, the sum of these three things is the artificial intelligence that is summarized today.
For what artificial intelligence can do, let's take a look at this picture:
The technological breakthrough of artificial intelligence has multiple sub-areas, which can be collectively referred to as "cognitive technology."
These cognitive technologies are advancing rapidly, providing faster action and decision making, better results, and greater efficiency. The potential commercial benefits of artificial intelligence are far greater than the cost savings brought about by automation, so in recent years attracted a lot of investment.
A good teaching scenario, in addition to the need for excellent content, depends more on powerful technology. For traditional education companies, if you want to move the offline education scene online, and also consider the teaching efficiency and effectiveness of the student teacher, you will often encounter the following problems:
System integration involves many developers, high transaction costs, difficult problem location, and difficulty in upgrading.
The service support of a single service provider is incomplete, the whole link technology is decentralized, the input cost is high, and the operation and maintenance is difficult.
Choose a normal PaaS cloud service provider, there are no scenarios and services for the education industry. Selecting a SaaS service provider, the upper-level business cannot be customized
For the cutting-edge technology like AR/VR, artificial intelligence, machine learning, etc., lack of manpower and funds for pre-research
In order to achieve the teaching effect, there are high requirements for online teaching scenarios, requiring strong interaction, high real-time performance, unlimited number of people, and strict stability.
For example, before the cloud classroom accesses Netease cloud communication and video, it adopts the scheme of the external manufacturer, and encounters the following problems that affect the learning effect and experience:
Incomplete function, lack of interactive live broadcast, whiteboard can only be painted by teachers
Poor performance, high concurrency is difficult to support, and some network environment students often watch
This complete and ground-breaking educational solution is suitable for educational applications such as K12, vocational training, MOOC and micro-classrooms, helping clients to quickly build the curriculum system, learning system, examination system, interactive system and operation and maintenance of the education industry. The system allows customers to focus on their core curriculum development and content operations, providing abreast of teaching interactions between teachers and students, and the continuous innovation of content and teaching forms.
In the existing online teaching case, what is the attention of the instructor?
Teaching effect
Teaching efficiency
For the teaching effect, the richness of teaching can be increased through diversified teaching methods. For example, in addition to optimizing the tutoring course, New Oriental is also eager to optimize the user experience during the course of the course, including understanding the enthusiasm of the students to participate in the course, the degree of absorption of the content, etc., so based on the existing technology selection, expand The direct communication between the students and the corresponding teachers (IM, chat room) helps the teacher to better maintain communication and follow-up support with the students online.
Under such a selection, the intensive course has achieved a good balance between optimizing curriculum resources and improving the service system. Combined with fragmented learning, teachers can communicate deeply with students and track learning outcomes.
For the teaching efficiency, all the links in the teaching process under the traditional teaching method are the responsibility of the same teacher, and cannot guarantee the input and learning effect of each student. So can we upgrade from a regular single teacher teaching to two teachers interacting with teaching? In the dual-teacher classroom scenario, we have a breakdown of duties, one teacher is responsible for the lecture, and another teacher is responsible for classroom management and after-school Sexual learning counseling. The overall structure, the teacher through the interactive teaching, teaching whiteboard and other tools to interact with students in real-time, the tutor through the online classroom, teaching whiteboard and other tools for after-school answers.
In addition, the future is also expanding the functions of adaptive learning and knowledge mapping, which uses adaptive recommendation algorithms to evaluate different students' learning levels, recommend learning content more accurately and efficiently, and help students participate more deeply. learning.
By connecting the entire educational solution, the geographical restrictions between teachers and students are broken, allowing educators and educators to experience a truly convenient resource sharing. Students interact with teachers in real time online, get instant access to the teacher's electronic board, teaching videos and ppt lesson plans, plus the data analysis and processing capabilities of AI technology, making students' learning effects and teachers' class efficiency even better than online classes. And can continue to enjoy stable operation and maintenance support, saving manpower and time costs, and can better adapt to the upgrade and transformation of the teaching system and client.
With the continuous development of artificial intelligence and supporting educational application layer, it will be applied to all aspects of the online education industry. Through the channel and means of the Internet, various barriers will be broken, so that everyone can receive education equally and efficiently.
