Compared with the current live broadcast and recording mode, the “Double Teacher Class†has become a new interactive teaching method tried by the K12 stage giants. This way, it is considered to be a deep combination of teacher teaching and real-time coaching, and is part of the smart classroom.
To put it simply, the double-teacher class originated from the traditional K12 chain extracurricular training institution, which was broadcast live by one classroom, and the other classroom or classroom was synchronized to listen and learn through TV or projection equipment. For students, the double teacher class refers to a student who enjoys the teaching services of two excellent teachers. A teacher is a lecturer with a wealth of teaching experience (famous teacher). He teaches students through large-screen remote live broadcasts, and is responsible for teaching knowledge accurately and efficiently. The other teacher is a tutor, who is responsible for maintaining the classroom order in the class, accompanying the students throughout the class, interacting with the students, counseling the students to learn and answering questions, and being responsible for the learning effect.
With the maturity of video live broadcast technology, the "double teacher classroom" has evolved into a "double teacher live class." The “Double Teacher Live Class†is a real-time interaction between the live teacher and the remote student on the basis of helping students to listen to the teacher in real time through live video. Solution providers can now implement 1:1 video rendering solutions and real-time interactive capabilities on low-bandwidth Internet. The teaching system is divided into a teacher and a student. The teacher's side is equipped with a full set of audio and video live broadcast equipment, which can transmit the teacher's teaching process in real time. In addition to the screen for watching the live video signal of the teacher, the student also has a clicker, microphone and other devices that interact with the live video teacher.
Compared with the previous standardized teaching mode, the dual-class classroom has its advantages:
First, the double-teacher class starts from the meaning of the word "learning" and solves the problems of "learning" and "study". “Learning†refers to the input of knowledge. The dual-teacher classroom mode enables more students to enjoy the resources of famous teachers; while “study†refers to the digestion and mastery of knowledge. Under the dual-teacher mode, the tutor acts as the head teacher. It solves the problem of lack of attention and companionship in the process of student learning, the lack of timely feedback on the homework, no answering questions, and the inability to give the wrong questions.
Second, the double-teacher class has enabled the original high-quality teaching resources to achieve several times the increase in production capacity. On the one hand, the growth of the number of students brought by a top-level teacher will break through the limits of classroom capacity; on the other hand, once the resources of the teachers are fully utilized, the company will have the strength to provide more favorable treatment for the teachers to alleviate the "teacher-oriented" The high turnover rate of training institutions. At the same time, the relationship between the tutor and the instructor will reduce the proportion of student turnover caused by one's departure.
Third, the double-teacher class is expected to ease competition among peers and open a new mode of cooperation within the entrepreneurship. Advantageous enterprises with standardized teaching and research systems and teacher training systems will be able to achieve greater benefits by exporting quality teaching resources to their peers; local training institutions that are at a disadvantage in past competitions can provide tutors to match quality courses of superior companies. And occupy their own market, in order to achieve mutual win-win.
Of course, training institutions will also face new challenges:
First, under the dual-teacher mode, the selection of tutors will become a new problem in this industry.
The double-teacher class breaks the original teaching triangle (the teaching process consisting of learning content, learners, and teachers). In the single teacher teaching mode, the teacher not only plays the role of preaching, but also the two-way interaction with the students, so as to improve the teaching effect. In the dual-teacher mode, this two-way interaction is broken, replaced by the interaction of tutors and instructors, tutors and students. The learning effect of the students will be controlled to a greater extent by the tutor, and the tutor will play a vital role in the teaching process. While the instructor can focus on teaching, the tutor has taken on the heavy pre- and post-class tasks, and the more interaction with the students has enabled the tutor to determine the reputation of the organization to a greater extent. This puts higher demands on the quality and incentive mechanism of the tutor's dedication service. However, it is not the same that the tutor's salary is significantly lower than the instructor, and the personal development space is not enough.
Second, the double-teacher class poses greater challenges to corporate profitability.
On the one hand, the dual-teacher class will greatly exceed the traditional teaching mode in the investment of technical equipment. For some “teacher-oriented†training institutions, the promotion of famous teachers will also increase the advertising cost of enterprises, and at the same time, higher salaries will be required. To recruit and retain famous teachers, it is necessary to recruit more qualified tutors and increase the salary expenses of enterprises. It can be seen that the operating expenses of enterprises in the double-teacher mode will increase significantly. On the other hand, during the promotion period, the relatively low price of the dual-curricular curriculum has weakened the growth of operating income brought about by the famous teacher effect. Whether the famous teacher or the low price attracts students and parents needs further discussion.
From the perspective of the industrial chain, in the K12 extracurricular training industry, the industry chain companies participating in the “double teacher classroom†model can be divided into content providers, equipment providers and extracurricular training institutions. Among them, extracurricular training institutions are still the core link of the industrial chain.
I. Content Provider: The institutions with outstanding advantages in teaching and research systems such as Xuetong Mathematics, Jiayi Education, and Gaosi Education cooperate with the extracurricular training institutions in various places through the mode of curriculum output.
Second, equipment providers: Provide training institutions with visual interactive teaching equipment such as teachers and students, including projectors, monitors, and cloud platforms. At present, New Oriental and the future two major industry giants choose Weidu Technology as a equipment provider.
Third, training institutions: At present, the training institutions that adopt the dual-teacher classroom model mainly include New Oriental, Good Future, Gaosi Education, Mingshi Education, and Bump Education.
