K12 Online Education questions: Who's going to be the next Big Mac?

With the influx of capital, test-class start-ups are eager to get a slice of the big cake K12 online education.

Discard the paper textbook directly on the ape questions?

"The ape question bank's answer is very thorough, after reading I basically can understand this question test center, this can motivate me to do the initiative," Shanxi Zhou A class of 1302 Marth classmate told Tencent Science and technology; "The ape questions on the question table will have detailed analysis, can let me know which knowledge points still not well mastered, At the same time the wrong title can be automatically included for follow-up review, so it is helpful to the points. "1415 class of Wang Yuahao students added.

It is understood that Shanxi Zhou is currently the country's first discarded paper textbooks, directly in the ape questions on the question of the high school, covering groups for the whole and some of the senior students. Li Haiyong in an interview with Tencent Science and technology, said that since last December, the school began to enable the Monkey Bank, "each student has a different learning path, the monkey bank can bring them more personalized learning experience, why not try?" ”

President Li said that Zhou is also the first batch of schools to implement classroom reform. 2008 began to try, 2011 introduced a rollover classroom model, that is, students after class to consult the study materials and complete the exercise, in class to show their main, teachers play the role of the listener; in 2014, the school developed a comprehensive information goal, each student is equipped with a tablet computer, It is not surprising that such an open school uses the ape question bank.

When it comes to the question of apes and what needs to be perfected, Wang Yuahao admits, "some subjects are not rich enough." Marth agreed, "for our liberal arts students, history, political materials and simple questions, but such topics can not be answered on the ape question bank." ”

In response, Conco, director of marketing operations at the ape question Bank, said that the students ' reference to the problem was not abundant. Subjective problem correction has always been a problem, the current use of machine learning and other technologies can not be breached, can only say that the direction of future efforts. "But the English composition of this piece, our technical team has begun to make a preliminary attempt, now is to provide the model, will be able to achieve automatic correction." ”

For the students mentioned the detailed answer, Conco told Tencent Science and technology, "in order to ensure high-quality content of the test questions, the operation team on each topic will be strict, usually have to check back and forth five times." ”

Conco For example, the answer to a question is a, but 30% or more students chose B, then can be determined that B is a strong interference option, they will analyze the choice of B students to which knowledge points have not mastered, the follow-up question bank will intelligently push the relevant topics, in order to achieve the effect of intensive training.

"Problem shooting artifact" surging recognition accuracy rate exactly geometry?

At present, there are countless similar "shooting artifacts" in the market, and several have completed a huge amount of financing, such as this year just won the 18 million dollar a round of financing online answer the app avatar problem, to get SoftBank China 20 million dollar B round of financing learning treasure, as well as last year received 5 million U.S. dollars financing of the application Couba June.

APE Item Bank recently also launched a small ape search problem, is based on the depth of learning technology for middle school students of the photo search software, just on the line has accumulated 2 million of users soon. So what is the difference between the small ape search question and the above application?

Li, vice president of the ape Bank, told Tencent Technology small ape search problem is purely users to put forward the demand, they feel that the market on the application of the problem is not perfect, and the ape Bank itself's technical team has the ability to provide such a technical solution, so less than three months, small ape search problem on the line.

"Our philosophy is to do the user needs, but the market can not meet the products." And some products such as translation dictionaries, on the market like Youdao such products have been very mature, we do not need to intervene. "At the same time, Li stressed that the core products of other companies may be the use of their photo search, but the small ape search questions is only a supplementary tool of the ape Question bank.

There is no doubt that the most important thing about "shooting artifact" is to identify the accuracy rate, in the interview with Tencent Science and technology, Ape Bank market operations director Conco revealed that small ape search questions can identify all the printed text and some handwritten text, recognition rate of more than 80%; Learning Treasure founder Huang Tao said that they use OCR technology, recognition accuracy of up to 85% Above。

Couba said that the use of STR technology, in the natural environment to capture the accuracy of the identification rate of about 90%. But the users who really tried the app said that none of these products were accurate enough to actually reach their published figures.

Although the question will have a certain randomness, some vague, some handwriting, but homework help, Aicola and so on "question and answer artifact" on the real problem students have these characteristics, users will be the students to shoot the subject of different subjects directly uploaded to the small ape questions bank, learning Bao Couba June, the result is the same as above.

How hard is it for users to become commercially available?

According to the Tencent class recently released a "K12 Education market Analysis Report" shows that K12 students on average daily counseling time in 1.5-2 hours, of which 57% of the students participate in various kinds of extracurricular tutoring, more than half of the parents will take the initiative to send children to participate in counseling. This shows that K12 online education market volume is huge, there is a lot of imagination space.

At present, K12 online education products, the official release of more than 10 million registered users, including the ape Question Bank, learning treasure, Baidu job help and a job network, they will appear in the next ten years a Big Mac? What are some of the difficulties that need to be overcome behind the huge number of users?

First of all, the high degree of homogeneity of products. Take "photo Artifact" to give examples, with the image recognition and in-depth learning techniques such as continuous improvement, photo search products has become a start-up company a new direction of choice. In addition to learning Bao Couba June, there are new to join the small ape search questions, and even Baidu homework help in the original UGC student question and answer model, added a photo search function.

Second, tens of millions of users are not sticky enough. May be the product has not achieved significant differences, student users will be compared to choose the best one of the results. The problem is that the product lacks uniqueness, and no one has been able to tie the user tightly.

Finally, the commercialization of the road is not clear. Learn Treasure founder Huang Tao told Tencent Science and technology, they are actively exploring new business model, such as learning Treasure 2.2 version on line, add the teacher audio explanation function, audio one yuan, income from learning Bao teacher divided.

Baidu Homework Help Although there are students circle such functions, active users are also very many, but the relevant person told Tencent Technology, there is no profit, commercialization of the road is not particularly clear.

In the case of the Ape bank, although its re-commissioning of the Chalk Question Bank (for vocational training) has been profitable, but the question bank this piece is still not see the commercialization of the signs. Ape, vice president of the Li told Tencent technology, will wait for users to accumulate to a certain extent will be considered. 15 million, 20 million or more? Li did not give a definitive figure.
