Is online education entering the era of "artificial intelligence" an outlet or another capital bubble?

One, open the door, the robot teacher arrived

In the past few days of the National Day, Henan, the birthplace of Chinese civilization, has just staged a scene of new technology: computers and people have launched a four-day man-machine war. This time, the opposing sides are no longer Li Shishi and Alpha Dog, but people's teachers and artificial intelligence teaching robots. The competition project is no longer Go, but "teaching and educating people."

In the Central Plains, where the ancient civilization had been nurtured, Confucius thousands of years ago could not have imagined him. As a master of dispelling misfortune, the true successor and challenger of his latecomers is not a person, but “artificial intelligence.”

What about the level of teaching of this latecomer? How is the result of the man-machine war? How to teach robots? Student's score will increase? This series of mysteries are all in desperation.

From October 1st to 4th, the activity organized 78 middle school students to conduct a round of mathematics test. According to the results, they were divided into two groups. They were taught by teaching robots and real senior teachers. In four days, targeted and focused teaching and counseling was conducted. After the end of the test, a round of testing was conducted to account for the increase in scores of the two groups of students.

Of course, in order to ensure the fairness, fairness and openness of this man-machine war, according to the organizer's education for dropout, a total of four measures have been taken to ensure the authenticity and effectiveness of participating in the test sample:

1. All third-party public school teachers are responsible for the questions and corrections of all test questions.

2, the introduction of Ereli and a number of media for full supervision.

3. All live video of the teaching process is open and transparent to the public.

4. The media and third-party organizations randomly sample exam questions to ensure that there are no leaks.

The four-fold measure, four days passed. The result of the man-machine war was: Machine teaching rolled down real teaching and scored 26.18 points (real people) at 36.13 points (machines) on the core average score.

Finally, after online education has gone through the cycle of fanaticism - freezing, the new era begins to show.

Second, online education, looks very beautiful

For a long time, online education has long been a favorite for Internet users and investors. After all, the huge amount of the 1.6 trillion education market and people's needs are very strong, but there are too obvious pain points in the traditional education at this stage, that is, two limitations:

1, the limitations of educational resources. Although we have been emphasizing “teaching without class” since ancient times, the quality of teaching resources is undoubtedly scarce compared to a large population and cannot be enjoyed by all people without discrimination. According to statistics, only 1/10,000 students can enjoy special grade teachers, and most students face ordinary low-quality teachers. As a result, quality education resources can only be increasingly concentrated in predominant regions, while disadvantaged regions are increasingly lacking resources, and the Matthew effect is thus formed. Of course, the most terrible thing is not only that, the poor educational resources in poor areas will not be evenly distributed among schools, grades, and classes, and the parallel classes will give way to the strengthening of classes. I believe every person who took the exam It will not be unfamiliar.

2, the teacher's energy limitations. Although we have been emphasizing “teaching students in accordance with their aptitude” since ancient times, teachers are not Superman. His time, energy and ability are limited, and it is impossible to take into account the learning level, stage, ability and personality of each student. As a result, traditional education adopts fixed teaching content, fixed teaching patterns, and fixed teaching methods. This standardized and streamlined method is a taboo for education! In doing so, it is impossible to teach students in accordance with their aptitude, teach indefinite methods, and teach the teaching philosophy of nothing.

Based on the above two conditions, it is not difficult to find that traditional education has been accompanied by a strict or even brutal "selection system" from the very beginning. High-quality educational resources have been concentrated in advantageous regions, and outstanding teachers' energy has been concentrated in a small number of excellent students. This is also doomed, the school will produce a group of "abandoned", "can not keep up" people, commonly known as "study dregs." (The writer prefers to call them as inferior students.)

In many cases, backward students are not raw and unruly, and they are difficult to learn from the beginning, but because they have been abandoned from the beginning and are unable to keep up with the progress of teaching, thus dampening their interest and confidence in learning. Once you find a way to meet with a teacher, you can quickly enter the fast lane.

To enlarge it, as long as someone can solve the problem of teaching resources in backward areas? Within a class, as long as they can save the undergraduates who cannot take care of them? Then anyone can get a share of the education market. In this case, online education seems to be an antidote. Especially since the outbreak of the mobile Internet, the influx of people has been very popular. By 2015, it was accompanied by "Academic" A large round of 50 million U.S. dollar financing has entered a climax.

Everything seems to be so natural, it feels like someone wants to set off a wave of education?

The ideal is so full and realistic?

Third, can not afford the Adou

In short, these savage people, who are full of ambition and involved in a large number of banknotes ramming into the education market, are full of greed in every pore of their bodies, and they can all sense their ambitiousness in the air. However, so many beachheads do not fall into these categories:

1, learning tools. This is a kind of primary and low-cost operation. It confesns that the early institutions did nothing more than grab the business of the Wenquxing and the backgammon dot reading machines. Of course, it is understandable that they are the pioneers of the first generation of Internet-based education. From the beginning of scallops, hundreds of words, to more intelligent tools to speak fluently, together with homework network, learning tyrants, from the back of words, spoken language recognition, layout and correction operations, photo answering questions, etc., a single point of education. A large number of customers have been obtained. Some time ago, the disputes between Huang Jia and Xiao Biao’s search questions have been fully disclosed. This fully demonstrates that the competition can be described as tragic.

2, online teaching. Speaking of the word online, we have to mention a software YY live, because with this powerful flow of the game entrance, do not know the feelings or business layout, "YY education" was so derived. At the beginning, Li Xuelin and Li Jun, together with 1 billion Lei Jun, wanted to marry New Oriental. As a result, people in New Oriental were better off. The most common search for “YY Education” was the capital chain breakage and strategic mistakes. It was also an irritating one. Seconds.

3, docking platform. When Didi hit the car and swept across the land of China, the education sector began to use the idea of ​​the o2o model. From the initial "91 foreign teachers" that Gong Haiyan had fallen to, the "teachers came" who died in the B round and asked him to teach "Initially, all of them are based on creating intermediary and bridges, and teachers and students are driven by the platform of docking, online transaction + offline conversion." With the high cost of teaching and the management and quality control of the quality of teachers, there are only the remaining $100 million of tutors and other students who have learned that the two or three giants monopolized the past tutoring market. Others have obtained more than 20 funds for financing. Institutions have disappeared.

4, MOOC teaching. MOOC (Moo) is an online education standard with a gold key origin. Yuan Yu, former deputy head of Tsinghua University, pointed out at the "Intelligence Education Seminar of the Ministry of Education Online Education Research Center" held in September this year that MO education is In an international education reform, China will be called the leader in this wave, not chasing it. It sounds very high-end and, to put it plainly, it is like Harvard Yale's open class and the Khan Academy on yutube. It simply puts the teacher into a video on the internet and students can't see it and see it. No one knows.

5, online one-on-one. Just as classmates' driving licenses have the so-called business executive president classes, the most common way to promote online education is one-on-one. Any exclusive service will always make people feel full of experience. However, 51Talk, the industry’s “first online education company listed in the United States,” recently released its Q1 earnings report in 2017, which is not good-looking. Its loss reached 140 million yuan, and the loss continued to expand. The financial statements of 51Talk in recent years have been in a state of loss from the pre-listing of 2013 to the present. In 2016, the losses amounted to 544.8 million yuan. The proportion of online one-to-one high marketing costs and teachers' costs is remarkable. Only vipkid saves a lot of marketing costs and becomes a dark horse with a 90% continuation rate.

Although these players have received a huge amount of funding or listing aura, their progress is not smooth: the tools are struggling under the huge flow of money because there is no matching income or completely transformed into another high-income business model. Although MOOC teaching is not bad, but the song is high and low, Coursera's white paper shows that the completion rate of the student's course is only 4%. The one-on-one online high marketing fees and high teacher cost curses also need to wait for the break. The reason why everyone is playing this way is the same. The reason may be as follows:

1. Online education is superficial. The course is still the course. The explanation is still explained. The only place where the class changes is from the classroom to the mobile phone and the computer. However, traditional education is "online" but it does not solve the most fundamental problem. Oh, in the past when TV was fired, it was called TV University. Now that the Internet is on fire, it is renamed online education. Is online education simply moving offline to the line or is it improving the level of education and the efficiency of learning?

2. The water in the education circle is very deep. What is the top three in national attention? Housing, medical care, education. However, these three areas are precisely the areas in which the Internet is most difficult to make achievements. The general Internet companies cannot play and they often fall into the pit of heavy model. The most important thing is that education is related to the national economy and the people's livelihood. The relationships that need to be dealt with include the government, schools, teachers, students, and parents. Such multi-tiered relationships need to be addressed. Not to mention the process of teacher teaching. Several hundred hours later, the knowledge reserve, teaching skills, children's personality and specialty, and the depth of cognitive psychology of pedagogy are far more than the hours of buying and selling a house and visiting a doctor. Disease is more complicated in a few weeks.

3, the application scenario is very careful. Different from the high-frequency, just-in-demand and standardized demands such as taxi and take-away, education itself is characterized by heavy decision-making and non-standardization. In particular, parents will make repeated comparisons and then negotiate with their children before they finally decide. Therefore, educational flow transfer income is a false proposition. Everyone can stroll around and buy hundreds of pieces of clothes to buy a few dozen pieces of the book, but they will not suddenly stroll thousands of thousands of dollars to buy a child.

4, attention is very anti-human. No one can solve the curse of "attribute scarcity" because the student stage wants to concentrate, which itself is a very anti-human. The lack of a restrictive learning atmosphere in online education has the result that students often cannot complete the course when they purchase a course. Of course, there isn’t much of an adult in this matter, just as if you went to know that you bought a live class. How many of you can listen to it all?

The predecessors accompanied by online education have been slammed into the sand. At the dawn of the AI ​​era, do we have some new ideas to solve this problem? As the latest generation of solutions, artificial intelligence teaching stands out.

Fourth, artificial intelligence teaching, where is wisdom?

For a long time, both venture capital circles and academic circles have been intentionally or unconsciously "mysterizing" personalized teaching systems based on artificial intelligence. If you say, today's headline is based on artificial intelligence, understand each person's interests and hobbies, recommend him to focus on content. Then artificial intelligence teaching is based on artificial intelligence to understand each student's knowledge points to grasp the state, learning ability, learning progress, stages and characteristics, and give corresponding teaching.

In short, an artificial intelligence teaching system should have three elements:

1, can touch bottom. The cognitive diagnosis model can be used to determine the corresponding knowledge acquisition status based on the student's response data, rather than the traditional determination of the score.

2. There is "ammunition". The teaching knowledge can be subdivided into a number of knowledge points, teaching methods, and form a flexible and flexible system. Relevance between knowledge points and learning ability, thinking ability, study habits, and learning content.

3, will be updated. According to the student's different stages of the knowledge of the accounts, the algorithm can also be continuously optimized and updated. Of course, all knowledge points have their own set of algorithms and data systems that are iteratively updated.

Although artificial intelligence teaching is completely unfamiliar to the public relative to "artificial intelligence", it is not a new concept for the academic community. In the West, there have been more than a decade of development history. The most famous of these is the intelligent adaptation of Knewton in the United States. This field has been cultivated for more than 10 years and has been widely recognized in the past three years. There are already 3,000 primary and secondary schools and universities in Europe and America. Institutional artificial intelligence education technology. Knewton's “Adaptive follow-ups” product, which can be adapted to the needs of students, can arrange different tasks and assignments for students according to their needs. A large-scale study on the product analyzes approximately 288,000 out of approximately 6,400 courses in the 2013 summer and fall semesters. The answers submitted by the students, the results of the study showed that the students who used the product in the course were on average 4 percentage points better than those who did not use the product. After Arizona State University introduced the mathematical artificial intelligence teaching course introduced by Knewton, the student pass rate increased by 17%, the dropout rate of the course dropped by 56%, and 45% of the students completed the course four weeks in advance.

In fact, the man-machine wars mentioned at the beginning of the article have precedents. Students studying at Pearson MyMathLab at Reading Community College in the United States were 12.5% ​​more likely than students who did not use mathematics. Pupils at a primary school in Miami used Waggle daily to review the Florida Unified Test. In a new and more difficult test in 2015, students from grade 3 to grade 5 performed better than other students in the same region, and English and mathematics subjects averaged 10% higher. Waggle is an artificial intelligence teaching system for k-12. CitySprings Junior High School is a public school. After using Waggle, in the reading subjects, the school has improved the ratio of teaching effectiveness tests by the Northwest Association of American Measurement Association by 25%. In mathematics, grade 7 students have increased their scores by 13%, while other grades have increased by more than 20%.

In these man-machine wars, artificial intelligence education showed three bright spots: the average score of students using artificial intelligence teaching was higher than that of students receiving artificial teaching, and the effect of promotion was significant; the passing rate was generally improved, and the effect on poorly-based students was achieved. This is particularly evident; students can complete their learning tasks in advance and their learning efficiency is significantly improved.

The tune has already been approached, and a large number of educational companies have started to flow in and out of the globe. In the United States, Knewton, Realizeit, ALEKS and other veteran institutions have received huge amounts of financing and extensive applications in recent years. Australia’s learning platform SmartSparrow has also received a US$14 million Series B round of financing. India’s byju’s has gained access to transforming artificial intelligence teaching. With more than US$100 million in financing, South Korea’s KnowRe also gained investment from Softbank and flourished. In addition, traditional non-artificial intelligence teaching institutions in the United States have begun to transform artificial intelligence teaching. Coursera and Khan Academy also announced the transition from MOM to artificial intelligence teaching in July and September this year. The traditional language learning platform Duolingo also turned to artificial intelligence teaching, and obtained 83.3 million US dollars in financing.

In China, a bunch of startups are pouring into artificial intelligence. In addition to the above-mentioned man-machine wars, the first school to use artificial intelligence to focus on ALLIN, there is the learning robot robot learning tyrants, the National Science and Technology 863 science and technology of the University of science and telecommunications, intelligent question bank counseling, oral practice APP Fluently speaking, LAN, and so on have all transitioned from the original field of artificial intelligence teaching. Similarly, the performance of these companies in the capital market is also very bright.

After dropping 120 million in angel rounds, the dropout education is said to have been doubled by a well-known fund within three months. Xue Bajun has already accumulated 370 million yuan in financing, and he has rapidly raised 100 million U.S. dollars after college entrance examination robots; It is even more favorable for IDG, Tencent and Jingwei China to raise 150 million U.S. dollars; fluency says that the transition “understands you English” is also swiftly mobilized to 100 million U.S. dollars; after HKUST’s focus on online education and assistance with AI, the price-earnings ratio Soaring. From one side, money is chased by artificial intelligence.

Of course, the articles made by these companies are also different. Their exploration mainly focuses on:

1, Science and Technology News. AI identification type, mainly in speech recognition, natural language processing, derived language assessment, composition correction system and other applications.

2. Dropout education. AI simulates an outstanding special teacher and gives students one-on-one personalized coaching. Using intellectually-accepted means to segment knowledge points and reinforce targeted teaching for the weak links of children. The main backbone of his team comes from KNEWTON and REALIZEIT, which combines intelligence adaptation and domestic K12 education.

3, learning tyrants. Through image recognition technology, it provided online junior high school students with on-line photo search service and introduced the college entrance examination robot this year to simulate real people's participation in the college entrance examination.

4, fluently said. Use real-time speech recognition and AI technology to score spoken English and mark out inaccurate places. Based on years of accumulated oral big data, combined with deep learning technology, we launched “Know Your English” in 2016. After users pay, You can enjoy customized teaching content.

So, is "artificial intelligence" the life-saving straw for these companies' financing, or will it really bring us a new era?

Fifth, it's easy to talk about, seven asked artificial intelligence teaching

The Alpha dog's victory over Li Shishi indicates that artificial intelligence has won in the highest intelligence segment of Go. In the field of man-machine war in the teaching field, if the most artificial intelligence teaching wins, it marks the most complex and important field of teaching and educating people. The dawn of the new era is coming.

The problems encountered by online education “martyrs” have been solved by artificial intelligence?

Education is a deep water and looks beautiful, but every road is a pit.

Here, we can at least see such major issues:

1. How to build a huge knowledge base and teaching information database? Knowledge is a vast universe, knowledge is one planet after another. So how does artificial intelligence teaching build this huge universe, and arranging every asteroid is a hurdle in front of the startup company. Moreover, AI builds a new universe, and all knowledge points and topics must be tailored to its rules and purposes, so all previous knowledge and data are completely ineffective.

2. How to solve the problem of inconsistent syllabus across the country? The earth is a common term used by us to describe China. The same education uses administrative divisions as a unit. Different local syllabuses are different, and the teaching focuses are different. It may be difficult to think of the same kind of people who support a hundred kinds of culture.

3. How to build the most powerful algorithm and truly understand each student? In the end, the algorithm is the logic of a program, and people are alive. The diversity of students has increased the difficulty of the algorithm. How to avoid the headline interest in reading too vertical is a social issue.

4. How to deal with the interests of schools and teachers? The promotion of intellectual adaptability cannot bypass the two barriers of school and teachers. The adaptation of the wisdom to adapt to the revolution is the existing education system. How can one sell people? How many people can help you count money?

5, how to solve the student's attention curse? This curse is a weakness of human nature. After artificial intelligence teaching lacks the constraints and supervision of the teacher, it is purely dependent on the subjective initiative of the students. In the end, it is very likely that the students are not immersed in learning at all.

6. How to solve parents' mistrust? No one wants to be a mouse to do this experiment, so no matter how good the adaptation is, in the final analysis, it still needs to accept the actual argument. So in the end, who would like to let the children accept artificial intelligence teaching and give up traditional education?

7. How to explicitly apply the results of the application and get support quickly? If everything is as conceived, how can this artificial intelligence teaching be able to get the results to the ground? It is no longer just a castle in the air, and it can achieve social and commercial benefits. The real spread of the business model is the absolute truth.

Six, the opportunity to overtake the curve

Despite numerous problems and difficulties, the prospect of full application of artificial intelligence teaching remains tempting.

From a small perspective, once one's system has been successfully implemented and fully implemented, it will promote the upgrading of the entire education industry. The winners of this track will become the general existence of the “hydropower coal” infrastructure and monopolize the education market in the new era.

On a large scale, once the teaching of artificial intelligence is successful in China, it will lead to an overtaking of the Chinese education industry and even the artificial intelligence industry against the United States. Imagine if China's special grade teachers were to be owned by every school-aged student, the entire education would completely solve the problem of inequality of resources, and it would be even more likely to further solve the social problems of current school district housing.

Artificial intelligence teaching is a subversive change to an industry. Just as the emergence of trains in the steam era, revolutionary changes to transportation; after the emergence of the Internet, Taobao revolutionized retail sales. Robots are better taught than teachers, and they are changes in the status quo of education over the past three thousand years. For thousands of years, human communication and communication have undergone tremendous changes. Education alone has not been much different from that of 3,000 years ago. The man-machine war has announced a new era. Artificial intelligence is a subversive revolution in the entire education field, and it has substantial meaning for the education industry and society.

However, as mentioned above, artificial intelligence teaching is not a place where pigs can breathe. If you want to play, this company is really unusual and must have the following capabilities:

1. Integrate quality educational resources and build an information base around the nature and needs of AI. Because the traditional knowledge structure is designed for people's teaching, just like the martial arts moves, it is useless now. The artificial intelligence teaching is to use the iron man's style of play to make full use of the advantages of machine performance, so we must invest in brand-new Reconstruction of a set of educational resource information.

2. Through advanced systems, cutting knowledge, achieving atomization and even nano-ization. Divide the knowledge of primary and secondary schools' teachings and sort out, and the finer the split, the better.

3, algorithm advantages. The algorithm here must be tactical. It is necessary to learn to find students' different learning strategies. Similar to AlphaGo, it cannot be a simple recognition type. AI engineers who match the answers to the questions through image capture, strategy type, and recognition type cannot Cross-border, a movie-like screenwriter, a similar camera, so is a completely different category of artificial intelligence. Identifying AI talents are more from Baidu and Microsoft Asia Research Institute, and strategic AI talents can only be imported from Europe and America.

4, the number of samples is sufficient. The rigid demand for learning is obvious, but the specificity is more prominent. Therefore, only enough students can use it to generate data volume in order to continuously optimize the algorithm. The choice of sample size requires samples that can be drawn from first- and second-tier cities to third- and fourth-tier cities and even five-county county towns.

5. Correctly deal with the relationship between schools and teachers. The natural resistance of the society and the people to new things requires that the inductors must be able to balance the interests of those who are divided.

6, strong GR capabilities. Can get the support of government departments and get school qualifications. At the same time, relying on the education department, we can quickly expand the awareness of public schools and the distribution of channels. The channels are relatively wide and the speed is relatively fast. For example, the cooperation of HKUST and the Central Committee of the Communist Youth League led to the development of their own education platform.

7, strong pr ability. Through some social actions, the society can be quickly informed of the results and win the trust of parents. The college entrance examination robot participates in the college entrance examination, and the teaching robot with the dropout education defeats the senior teacher. The branding activities that easily lead to the attention of the general public need regular planning.

8, excellent professional team. Team members must have strengths in all directions. The intellectual adaptation laboratory based on Ai is indispensable. Team members should have experience in the education industry, for example, Dr. Cui Wei, chief scientist in the dropout education team, in the complexity system. The frontier domain evolutionary algorithms and group intelligence algorithms of modeling and artificial intelligence have been deeply studied and have outstanding results, and have served as members and judges of several international academic conferences on artificial intelligence and algorithms. Lin Hui, the chief scientist of CTO who is fluent in the past, has served as a research scientist at Google USA headquarters and has in-depth research on speech recognition, machine learning, and big data mining. The founder of dropout Lihao Yang has some 18 years of product R&D experience in the education industry. In addition, Chen Xiangdong, the founder of the company who is familiar with the promotion and profit model in the commercial field, is the president of New Oriental. The educated school ceo Zhou Wei is responsible for the development and sales of more than 2,000 K12 schools across the country, and has obtained innovative workshops. The CEO of the investment-study classroom is the Vice President of Giant Education.

Artificial intelligence teaching as a new upgrade of online education, people see hope, it is inevitable that some worry. Like a toddler, we know he will fall, but he will surely run in the future.

In the end, I want to say that education is called a century-long plan. Japan relies on education as a strong Asian country and Singapore relies on education as a “four dragons”. If artificial intelligence teaching can help more and more children improve their grades easily and efficiently, perhaps more children can change their destiny through the college entrance examination. Of course, youngsters are strong in the country.

The future can be expected.
