Class factory shows alternative big data

Show Class Factory _ Data Analyst Exam for Replacing Big Data

Studios, spotlights, reflectors, props, assistants and even directors, Song Shuai felt that he had entered a specific crew. Yes, he is the "first hero", but unfortunately, he is not the kind of sexy and hot heroine full of royal elder sister's amorous feelings, but a high number. As a university teacher, in order to make the course more lively and interesting, Song Shuai cooperated with an online course production organization named "Classroom Factory" in Guiyang to attract audiences with movie-like teaching videos and achieve the effect of "encouraging" learning.

He is not the first person to eat crabs. More than 20 teachers in the city used to be "actors".

In the movie? Hehe, record the teaching video.

The class factory is located on the first floor of the National Digital Content Industrial Park in Guiyang High-tech Zone, with two offices of several hundred square meters.

On the right is a modern cubicle, and the office area on the left is actually a studio, with DV cameras, tripods, wall coverings, reflective plates, reflective umbrellas, soft boxes and lamp stands ... plump. A director and an assistant director are sitting behind the camera, looking very absorbed.

"Slice. Your expression is too blunt, be vivid, just think of us as students, be natural and have another one. " "Director" Lu Junyu "tells the script" to the teacher who recorded the video, and stares at the camera intently, shouting: three, two, one, go.

This is the online recording website of "Class Factory". Through the establishment of "crew-style" and "film-level" curriculum production system, nine roles, such as curriculum director, curriculum planning and post-production, cooperate with teachers to produce online courses by means of live lectures, studio recording and broadcasting.

For example, this university teacher who is recording a video is talking about Tao Yuanming's "Returning to the Countryside". In the past, the "background board" only had a blackboard, but now she participates in "film and television teaching", and the "crew" will deal with synthetic animation and 3D special effects in the later stage, so that students can attend classes like watching movies.

Wearing a headset is "Lu Dao", and it is General Lu who walks out of the studio. Although most of the workers in the class factory are "small fresh meat" born in the 1990s, most of them are highly educated talents who are proficient in data collection, video editing, animation synthesis and other fields, and can also be "on-site reporters", "assistants", "lighting engineers" and "photographers". Usually, a "crew" needs 8 people to serve 1 lecturer.

Split the knowledge points and record a 3- 10 minute video.

Luo Cheng, the head of the design department of the class factory, said that the company was founded on 20 14, and chose the field of teaching video recording because it was optimistic about the huge prospect of the "internet plus" education market.

In the past few years, "open courses", or courses that are freely taken, have taken a great turn in the field of education. In China, more and more schools choose open classes instead of textbooks published by traditional education publishing houses, which is unprecedented.

The data shows that the number of online education users in China continues to grow, and will reach1.200 million by 20 17.

"This change is extremely popular. Using open courses, that is, open educational resources, can save some educational expenses. " When schools start to choose free courses, it means that they don't need to spend too much on printed textbooks, but only need to choose a web platform that can manage digital courses. For students, this free and personalized learning experience can help them master knowledge points faster.

However, although many schools gradually use the Internet for knowledge dissemination and academic exchange, it is difficult to attract students' attention due to the lack of relevant operational experience and skills. Luo Cheng said that a professional research institution once analyzed the sample data of 7 million online learners and concluded that the teaching video with a length of 6-9 minutes is the best. When the teaching video exceeds 10 minutes, the learners' attention drops obviously.

In order to "catch" students, the "leaving factory" videos of class factories are segmented by curriculum designers through diversified curriculum design, and the duration is concentrated in 3- 10 minutes. Improve ratings in a "short, small and refined" way.

Collect big data

Optimize to fill the loopholes.

At present, education curriculum is at the center of the ocean of change. The "hard life" of huge teaching materials and closed courses is gradually dying out. Emerging open courses can not only help domestic educational institutions save education costs, but also gather the professional wisdom of elite teachers across the country.

In Guizhou, there are currently more than 65,438+00 colleges and vocational schools cooperating with "Class Factory". Colleges and universities sent more than 20 lecturers to make the recorded teaching videos public in official website, and the videos can be recycled. The most important thing is that this redefined form of education and teaching breaks the time limit, and the key and difficult points can be watched repeatedly, so students don't have to worry about missing any knowledge points.

In addition, the class factory has also set up the Institute of Digital Media Education and Education, and independently created the "C .D .F.P.S Course Incubation System". Through relevant theoretical research and big data analysis, the concept of course production has been continuously upgraded. Luo Cheng introduced that class factories use big data to make teaching videos, and some people observe them in the background. "For example, it is found that some videos have a high replay rate at a certain node, indicating that this content may be difficult and many people do not understand it. We should give these data back to the school in time to further optimize the course and make the course more vivid. "

Maybe five years later, the teacher may say, "Remember when we bought such expensive textbooks? We can't adjust those books according to the needs of students. " It's like saying, "Remember when we put the film in the camera?"

The above is what Bian Xiao shared with you about the demonstration of alternative big data in similar factories. For more information, you can pay attention to the global ivy and share more dry goods.
