You wear a VR headset similar to Google Cardboard, and you see a stereo image shaped like a human brain floating slowly in the air. You have a controller in your hand that can be pointed at any part of the brain like a mouse.
You find that the entire brain is made up of countless lobes. You click on the brain and all the leaves are separated. You use the mouse to slide freely on the image and find out which leaf it touches, and that leaf will automatically appear a string of text to tell you what its function is.
You point the mouse towards the occipital lobe, and that line tells you that it is responsible for the visual processing. At this time, the system challenges you: can you put these scattered leaves back in place?
You reinstalled all the blades a little bit according to the text prompts you saw. When the last piece returns, the system will pop up a notification: You have won!
It turned out that the whole process just now is a game, a VR puzzle game about brain structure.
This is more interesting than the boring paragraphs in the textbook. You can't help muttering. Taking off the helmet, I thought about the experience just now
Veative Labs, the maker of the VR device, said that the simulation system they designed is to connect tangible knowledge with abstract cognition, allowing users to change from passive learners to active knowledge investors.
It is reported that this company's VR equipment for science and mathematics has appeared in many classrooms in 25 countries around the world. Its main function is to help students understand complex subject knowledge concepts:
People can easily see the effectiveness of this device in enhancing learning ability, but one often overlooked but the real fact is that this product can also improve the teaching ability of teachers. Because it can expand the teacher's knowledge reserve, Activate them to more potential. The company asserts confidently on its website.
Although VR (virtual reality) and AR (augmented reality) technologies are mainly used by a small number of elite private schools in education, fortunately, the government has already begun action. India's latest Draft National Education Policy 2019 clearly states that Science and technology achievements and technology applications must become an important strategy to improve the overall quality of education in India.
It can be imagined that under such a policy background, a series of educational software developed for teachers and year-round students will spring up like bamboo shoots. Among them, serious games and simulation education products that apply AR and VR technology will become the protagonists.
From a deep perspective, the widespread application of these products highlights the new technology's subversion and challenge to traditional teaching methods. From now to the near future, people will become more and more accustomed to online education: teachers carry out teaching activities at home, and students only need to use a mobile phone to receive learning materials and listen to lectures anywhere. In the past, even in the offline education scene, students' classroom participation was difficult to track through scientific means; but under the blessing of artificial intelligence technology and its important branch, Natural Language Processing, even education Activities take place online, and students' comprehension ability, analytical ability, and even the concentration of attention and changes in mood during class can be found, tracked and measured in time.
Face recognition technology can capture students' classroom participation in real-time and supervise the teaching effect of teachers; business-level AI tools can help students match colleges and universities and choose courses that suit their own characteristics.
The most amazing technology in this era is artificial intelligence. To be precise, it is machine learning and deep learning in the field of artificial intelligence. Sebastian Thrun, founder, chairman, and CEO of Udacity said excitedly. The Silicon Valley unicorn's main business is to provide users with a large number of online public courses.
AI can train world-class teachers. World-class teachers don't just speak, they listen. No matter where the students come from, they can understand them and make timely adjustments based on their specific circumstances. Thrun Added.
Udacity, founded in 2011, began as a laboratory set up by Sebastian Thrun and Peter Norvig. At that time, the two Stanford faculty members gave a free public course called Introduction to Artificial Intelligence on the Internet.
Compared with the content of the course, 'how can we make students learn better' is the focus of our concern. We believe that the teaching process is actually an interaction between the teacher and the student on the content of the lesson. When the student understands the content of the teacher This teaching link is effective; on the other hand, when students can't understand what the teacher said, there will be a fault in the teaching link and the teaching effect will be discounted. Udacity uses AI technology to analyze the entire teaching process and successfully locks in Specific teaching faults have further improved the learning efficiency of students. In addition, we also use AI technology to help merchants make pricing decisions. Through the detailed analysis, AI can find the most appropriate price point for products that meet market needs. This set of processes It's a bit like the daily work of Amazon's AI.
In addition to Udacity, Thrun is also the founder of Google X, and Google X gave birth to Google Glass, a self-driving car and wearable device.
Not only Silicon Valley, but in India, thousands of entrepreneurs have entered the education technology industry in recent years. According to data released by Data Labs, a research organization administered by Inc42 Media, India alone added 4,450 new education startups between 2014 and 2019. Although 1150 of them were forced to shut down, from a general trend perspective The field of education technology has already become a capital outlet. As of now, 194 education technology start-ups have received government funding; the funding pool in this area has also reached $ 2 billion. In terms of business content, a considerable number of startups have focused on improving hardware and software facilities for online training. From the perspective of India's national conditions, this is indeed a top priority: Due to the limited bandwidth, students in many parts of India have difficulty enjoying the convenience and efficiency brought by online education.
Like Thrun, Vamsi Krishna is also a teacher. In 2006, he and a friend in Punjab co-founded an offline training company called Lakshya, who is also a lecturer of the company. By 2012, Lakshya had become a well-known test design brand in northern India, but Krishna decided to sell the company because he found it difficult to expand the scale of his main business offline:
It's not easy to expand the offline training center on a large scale. If you want to open a branch school elsewhere, you have to copy the soul of the main school and ensure that you have the same high level of teachers. Both tasks are very important. Difficult. In order to expand the scale without losing the educational concept of the training center, and not to reduce the level of teachers, we must rely on technical means.
Krishna then co-founded an online course training company, Vedantu, with friends, which provides full-course instruction for students in grades 6-10. In the years when the company was founded, around 2016, Vedantu promoted one-on-one online tutoring; but it didn't take long for this model to become one-to-two, that is, a teacher More than 200 students were listening while teaching online. In order to establish a brand and expand market share, Vedantu also launched a free model. In the free online lesson, a teacher faced up to 2,000 students Krishna's teaching scale at the same time, and he did not guess that the means to achieve it depended on new technology.
