Distance teaching and double-teacher classroom: a screen connecting urban and rural areas

From distance teaching by lecturers, on-site tutoring by rural teachers, to whiteboard annotation in Q AI, student interaction and after-class resource sharing, this paper analyzes how Qtenboard support the coordination of urban and rural educational resources with 20 years of manufacturing experience and 330,000 ㎡ industrial park.

The real double-qualified classroom is not to broadcast the video of the city classroom to the rural school, but to let the lecturer, tutor and students work together in the same digital classroom. In the city lecture room, famous teachers explain the course in front of the camera, write formulas, display charts and play videos on the interactive whiteboard, annotate key contents through the whiteboard, and adjust the rhythm of the explanation according to the feedback from the rural classroom. In the rural receiving classroom, students watch the lecturer through a large screen. The local tutor organizes classroom discipline, auxiliary operation and answering questions. Students can write on stage or use terminals to participate. Classroom questions are fed back to the lecturer through cameras, microphones and platforms.

The interactive whiteboard undertakes the tasks of course presentation, digital writing, remote annotation and classroom content sharing, while the camera, microphone, video conference platform and network are responsible for connecting people and people. The infrastructure of a hybrid classroom typically includes an interactive whiteboard, a classroom-level camera, a microphone, a video conferencing platform, and a reliable network; the whiteboard is responsible for the content, and the video conferencing system is responsible for connecting participants.

1. what is a double class?

One speaker and one tutor to form distance collaborative teaching

1. The basic role of double-qualification class

The lecturers are responsible:Curriculum design, core knowledge explanation, key content blackboard writing, classroom questioning and interaction, learning progress control, curriculum evaluation and teaching feedback.

The tutor is responsible:Organize local classes, assist students in the use of equipment, manage class order, observe student reactions, collect questions, conduct local Q & A and personalized coaching, handle network/equipment and classroom emergencies.

Students are responsible:Watch and participate in remote courses, answer questions via whiteboard/personal terminal or voice, participate in group discussions, complete exercises and classroom activities, and view digital course content after class.

2. The difference between double-qualification class and ordinary live class

3. What problems do double-qualification classes solve?

High-quality teacher resources are unevenly distributed, it is difficult to continuously obtain high-level courses in remote areas, there are insufficient professional teachers in rural schools, students cannot access rich curriculum content, a single training or live broadcast is difficult to form long-term teaching support, and the reuse rate of high-quality curriculum resources in urban schools is insufficient.

The Core Role of 2. Interactive Whiteboard in Double-teacher Classroom

One screen, connecting content, teachers and students

1. As a "common canvas" for distance courses"

The lecturer writes at the city end and the handwriting is displayed at the village end simultaneously. Local teachers can add content on the same page. Students can take the stage to annotate or complete the answer. All participants share the same digital canvas.

The Qtenboard touch scheme supports 20-50 point touch, with a touch accuracy of 1.5mm, a single point response time of 7ms and a multi-point response time of 10-15ms. It is matched with Zero-Bonding zero-bonding technology and 1mm tempered glass to ensure smooth synchronization and no delay of remote annotation.

2. As the main teacher teaching window

Show PPT, PDF, web pages and videos, circle drawings and comments directly on courseware, switch whiteboard/video/pictures and teaching software, display students' answers and homework, and support multi-window teaching.

3. As an interactive entrance for rural students

Students can directly touch the operation, multiple students can write at the same time, support drag/classification/connection and sorting, through the personal terminal to send the answer, so that students from the viewer into a participant.

4. As a recording tool for classroom content

Save blackboard writing, save the host teacher's comments, record students' answers, export classroom materials, share after-class review content, support recording classroom or synchronization to the cloud (such as system support).

Qtenboard Q AI supports automatic saving of classroom blackboard writing, OCR recognition of handwritten content, and real-time translation of 166 languages, allowing rural students to review digital course content at any time after class.

How does 3. a double class work?

From pre-class preparation to after-class review, interactive whiteboard runs through the complete teaching process

1. Before class: the speaker and the tutor prepare lessons together

Teacher preparation:Course PPT and teaching resources, classroom questions, videos/pictures and experimental content, interactive activities, key blackboard writing pages, student exercises and evaluation criteria.

Preparation of tutors:Check the network and equipment, confirm the camera and microphone, turn on the whiteboard and meeting platform in advance, help students log in to the class, prepare local teaching materials/teaching aids and exercises, understand the students' foundation and the contents that need key guidance.

2. In class: remote explanation and local interaction are parallel

Teacher:Explain the course, write and comment on the whiteboard, observe the rural classroom through the camera, initiate questions and interactions, and adjust the course progress according to student feedback.

Tutor:Assist students to operate, maintain classroom order, collect students' questions, deal with equipment problems, organize local group activities, and provide supplementary explanations for distance courses.

Student:Watch the course content, participate in interactive questions, write on stage, answer through the microphone, submit answers using the terminal, participate in group discussions and after-class exercises.

3. After-class: course content precipitation and local tutoring

Save whiteboard notes, export courseware and annotations, share review materials, generate class summaries, arrange tutoring according to students' questions, host teachers check class feedback, analyze students' answers, and adjust the next course plan.

The Practical Value of 7. Urban and Rural Double Teachers Classroom

A screen, change not just classroom form

1. For rural schools

Get more high-quality curriculum resources, reduce the impact of insufficient professional development opportunities for teachers, participate in city school or education group courses, contact with science/art/English/programming and other characteristic courses, let students participate in richer interactive teaching, and review after class through digital materials.

2. To urban schools and lecturers

High-quality courses can serve more schools, curriculum resources can be reused, students in different regions can be learned through remote classrooms, a wide range of teaching feedback can be collected, digital curriculum assets can be formed, and the influence of teachers and the scope of educational services can be expanded.

3. To the local education administration

Promote the sharing of educational resources, unify the construction of distance teaching standards, unify equipment/platforms and services, monitor the use of school equipment, improve the efficiency of the use of special education funds, and support cross-campus teacher training.

4. to the students

Access to richer course content, increase opportunities for classroom participation, contact with different teachers and learning methods, understand knowledge through interaction/video/images and experiments, review blackboard writing and course materials after class, and improve digital collaboration and remote communication skills.

Interactive whiteboards can improve resource connectivity and classroom interaction, but cannot address the urban-rural education gap alone. Teacher training, curriculum quality, network coverage, equipment operation and maintenance and school management are equally important.

11. How to measure the effect of double-qualification class?

We can't just count how many screens have been installed, but also see whether the classroom has really changed.

1. Equipment operation index

Equipment online rate, success rate of course connection, equipment failure rate, number of network interruptions, remote failure resolution time, frequency of classroom equipment use, software upgrade success rate.

2. Teaching process indicators

The number of students' participation, the number of students' on-stage operations, the number of classroom questions, the completion rate of interactive activities, the frequency of collaboration between the lecturer and the tutor, the preservation rate of classroom materials, and the number of after-school review visits.

3. Teaching outcome indicators

Student homework completion rate, classroom test performance, course attendance rate, student satisfaction with the course, changes in teacher preparation and finishing time, differences in student participation between urban and rural areas, and changes in subject performance (e. g., after scientific evaluation).

4. Pilot project proposals

Select one or several urban schools and one or several rural schools, select the same subject and similar grade, run a complete teaching cycle, compare the classroom process before and after the use of the equipment, record the feedback from the network/equipment/teachers and students, do not attribute all the changes in pure grades to the equipment, and use the results for subsequent expansion decisions.

XII Common Misunderstandings

Double-qualification classes are not as simple as "installing equipment and turning on live broadcast"

Myth 1: Make Double-qualification Classes into Remote TV Classes

Students can only watch the lead instructor, with no local interaction and no remote feedback. The right way: design student operations, questions, homework and group activities.

Misunderstanding 2: Only purchase display screen, not build audio and video system

Remote teachers can not hear students, students can not see teachers and whiteboard. The correct way: synchronous planning camera, microphone, audio and platform.

Misunderstanding 3: Ignoring the training of tutors

The tutor was unable to handle the equipment and classroom interaction. The right way: include tutors in the process design before, during and after class.

Myth 4: Ignoring the rural network environment

The live broadcast platform is operating normally on the urban side, but the rural side is frequently Caton. The correct way: field network test, backup link and offline data parallel. Qtenboard Q AI core transcription runs locally, reducing network dependency.

Myth 5: Only one-time project budget

Lack of training, renewal, spare parts and maintenance after equipment installation. The right way: Use a five-year TCO and full lifecycle budget.

Misunderstanding six: the equipment coverage is equal to the teaching effect

Installation completion does not represent teacher use. The correct way: continuous statistics of equipment utilization, interactive data and teaching feedback.

Conclusion: The value of a screen lies in making two classrooms truly one classroom.

The double-qualified classroom solves the problem of connecting educational resources, not a simple video transmission problem. Interactive whiteboards allow remote content, teacher annotations, student interaction, and classroom material sharing to occur in the same space. Cameras, microphones, networks, video conferencing platforms, LMS, device management and teacher training are equally important. Urban lecturers and rural tutors should form a collaborative rather than alternative relationship.

The real value of distance learning is not to allow rural students to "see" the urban classroom, but to enable them to participate in it, ask questions, complete tasks and get continuous feedback. An interactive whiteboard in the double-qualified classroom is not only a digital platform for the lecturer, but also an interactive entrance for rural students, and a platform for the preservation, sharing and reuse of course content.

QtenboardBacked by 20 years of manufacturing experience, 330,000 ㎡ industrial park, 8 full-automatic production lines, Q AI system-level framework, Genio 520 platform (10 TOPS equipment-side AI) and DMS equipment management system, it provides a complete scheme from 55-110 inch hardware, 20-50 touch, 166 language AI to Android/Windows OPS dual system, OEM/ODM customization and CKD/SKD localization for global double-qualification classroom projects.
