Course factory show alternative big data_Data Analyst Exam

Studio, spotlights, reflectors, props, assistants, and even a director, Song Shuai feel like crossing into a theater group acting. Yes, he is the "number one man", but unfortunately the role is not sexy hot, full of imperial style heroine, but the higher mathematics. As a university teacher, Song Shuai in order to make the course more lively and interesting, and Guiyang, an online course production organization called "class factory" to cooperate, such as film-like attraction of the audience's teaching video, to achieve the effect of "motivation" learning.

He's not the first to take the plunge, but more than 20 teachers across the city have been actors before.

A movie? Oh, recording teaching video

The class factory is located on the first floor of the National Digital Content Industry Park in Guiyang's high-tech zone, with two offices of hundreds of square meters.

The right side is a modernized grid room, the left office area is actually a studio, which has a DV camera, tripod, wallpaper, reflective panels, reflective umbrellas, softboxes, light shelves ...... rack. A director and assistant director sitting behind the camera, look focused.

"Click. Your expression is too stiff, a little more vivid, just think of us as students, a little more natural, another line." "Director" Lu Junyu gave the teacher who recorded the video a "speech", stared intently at the camera again, and shouted: three, two, one, start.

This is the "class factory" online open course recording site, through the establishment of "crew type", "film and television level" of the course production system, by the course director, course By establishing a "crew-style" and "film-level" course production system, the nine roles of course director, course planner, and post-production work together with teachers to produce online courses using live teaching and studio recording methods.

For example, the college teacher who is recording the course she narrated is Tao Yuanming's "Returning to the Garden", and in the past, the "backdrop" was only the blackboard, but now that she is taking part in the "film and television teaching", the "crew" will be synthesized in the post-processing stage. "will be in the post-processing synthesis of animation, 3D effects, so that students like watching a movie on the class.

Wearing a headset is "Lu guide", out of the studio is Lu total. Although the staff of the class factory is mostly made up of post-90s "fresh meat", most of them are highly educated, and they are good at data collection, video editing, animation synthesis, etc., and at the same time, they can also be divided into "field recorders", "assistant", "assistant", "assistant", "assistant", "assistant", "assistant", "assistant", "assistant", "assistant", "assistant", "assistant" and "assistant". assistant", "lighting technician", "photographer". Usually a "crew" needs 8 people to serve a lecturer.

Splitting the knowledge points to record 3-10 minutes of small video screen

Class factory design department responsible person Luo Cheng, the company was founded in 2014, the selected teaching video recording field, because of optimistic about the "Internet +" the huge prospects of the education market.

Over the past few years, "open courses," or courses that are optional and free, have seen a huge turning point in education. In China, more and more schools are opting out of textbooks issued by traditional educational publishers in favor of open courses, a phenomenon that has never happened before.

Data shows that the scale of online education users in China continues to grow and will reach 120 million by 2017.

"This transition is extremely popular, and the use of open courses, also known as open educational resources, can save a certain amount of money on education." When schools start opting for free courses, it means that they don't have to spend much on printed textbooks, but simply choose a web-based platform that is able to manage the digital curriculum. For students, this free and personalized learning experience can help them grasp knowledge points faster.

However, although many schools are gradually adopting the Internet for knowledge dissemination and academic exchanges, the self-recorded videos of colleges and universities are hardly able to attract students' attention due to the lack of relevant operational experience and skills. Luo Cheng said a professional research organization had analyzed data from a sample of 7 million people studying online and concluded that teaching videos 6-9 minutes long are the most effective. More than 10 minutes of teaching video, the attention of learners dropped significantly.

In order to capture the attention of students, the videos produced by LessonWorks are designed by course designers through a variety of courses, which split a number of knowledge points into small video clips of 3-10 minutes in length. In a "short, small, concise" way, to enhance the ratings.

Collecting big data

Optimizing to fill in the gaps

Currently, educational curricula are at the center of an ocean of change. The "hard days" of huge textbook costs and closed courses are dying out. The emerging open curriculum will not only help China's educational institutions save money, but will also bring together the expertise of elite teachers from across the country.

In Guizhou, there are currently more than 10 colleges and universities, vocational schools and "class factory" cooperation, institutions sent more than 20 lecturers, will be recorded on the official website of the teaching video to the public, the video can be recycled, the most important thing is that this redefinition of the form of education and teaching to break the time constraints, the focus of the difficulties can be repeatedly watched, the students do not have to worry about missing any knowledge points, the students will not have to worry about missing any knowledge points.

In addition, Lesson Factory has also set up the Digital Media Education Research Institute, the original "C .D .F.P.S course incubation system", through the relevant theoretical research and big data analysis, and constantly upgrade the concept of course production. Luo Cheng introduced that the course factory utilizes big data to produce teaching videos, and there are always people in the background to make observations, "For example, if we find that some videos have a high replay rate at a certain node, it means that the content may be difficult and many people don't understand it. We have to feed this data back to the school in time to optimize the curriculum further and make it more vivid."

Maybe in another five years, teachers might meet and say, "Remember when we used to buy all those expensive textbooks? Those books just didn't allow us to adapt them to the needs of our students." It's like saying, "Remember when we stuffed film in our cameras?"
