Teacher Guide
This page explains every teacher feature one by one: what it is, how to operate it, its options, who it affects, and what students see. Use the left-hand outline to jump around.
Launch & select a teaching channel
Double-click the cc-class Teacher desktop icon. On first entry you select a teaching channel:
- What a channel is: a "code" that separates classes on the same LAN. A student only connects to a teacher on the same channel.
- How to choose: adjust the number (1–100) with
–/+, then click Enter Classroom. When several classes run at once in one room, give each class a different channel. - Conflict detection: if the channel you pick is already used by another teacher on the same subnet, you'll see "channel already in use" — pick another.
- The top-right corner switches the interface language (Chinese/English/Japanese/Korean…), with identical button positions.
Students can only connect after you "Enter Classroom"
The main window only starts accepting student connections after you enter the classroom. While the channel/trial dialog is open, students cannot connect.
You then reach the main window:

How to choose the target:
- All students: most features (broadcast, cinema, block internet, black screen…) apply to all online students by default.
- A single student: click to select or right-click a card for the single-student menu; double-click to remote-control that student directly.
1. Screen broadcast & teaching presentation
This group is for "showing a screen to students". Usually only one runs at a time; starting a new one stops the old.
1.1 Screen Broadcast
Broadcasts the teacher's own screen to all students in real time.
- How: click Screen Broadcast → in the mode dialog choose:
- Full screen: broadcast the whole desktop.
- Window: broadcast one specific window only (students see nothing else — good for demoing a single app).
- Affects: all online students (a student currently being "presented" is excluded automatically).
- Annotate while broadcasting: an annotation toolbar appears — pick pen color/width, eraser, shapes, and draw over the screen to explain.
- Students see: a full-screen window of your screen pops up; while watching, F2 takes a note-screenshot, saved to
Documents/课堂笔记/(Class Notes). - Stop: click the button again (now labelled "Stop Broadcast").
1.2 Student Presentation
Forwards one student's screen to the whole class — for having a student demonstrate.
- How: click Student Presentation → pick the student in the list dialog; or right-click the card → Start presentation.
- Side effects: that student's screen is broadcast to everyone else, and a remote-control window for that student opens for the teacher (you can take over any time).
- Affects: the 1 selected student (their screen → everyone else).
- Stop: click "Stop presentation", or right-click the card → cancel presentation.
1.3 Video Livestream
Streams "screen + camera + audio" to students at once — ideal for narrated, on-camera teaching.
- How: click Video Livestream to toggle on/off. Turning it on also starts voice broadcast and opens the annotation toolbar.
- Affects: all students.
- Students see: a full-screen view of your live feed.
1.4 Cinema
Plays one video file in sync to the whole class (lessons, clips, etc.).
- How: click Cinema → choose a video (
.mp4 / .mkv / .avi / .mov / .wmv) → all students play it together. - Teacher side: a separate player window opens so you can monitor playback.
- Affects: all students.
- Stop: click "Stop playback". Starting cinema automatically stops broadcast/livestream/presentation.
1.5 Shared Whiteboard
Opens a real-time shared canvas — the teacher writes/draws and students see it live, like an electronic blackboard.
- How: click Shared Whiteboard to open; use the annotation toolbar for color, pen width, eraser and shapes.
- Affects: all students.
- Stop: click "Stop whiteboard".
2. Classroom interaction
2.1 Random Roll Call
Picks a random student with a scrolling animation.
- How: click Random Roll Call → a scrolling-animation dialog appears (students see the animation too, for atmosphere) → after ~3 seconds one student is locked in.
- After picking: one click on "Share screen" presents that student's screen to the class (starts their presentation).
- Affects: 1 random student.
2.2 Discussion / chat
A classroom chat room.
- Direct click: opens the "all-class" group chat window.
- Drop-down menu:
- Open chat window: the teacher can send text, emoji, images, files, screenshots.
- Allow / forbid student chat: toggle whether students can post.
- Group discussion management: create/manage discussion groups; switch "group ↔ back to all-class".
- Students see: once allowed, the "Discussion" button on the student toolbar becomes clickable, opening the chat (supports Ctrl+V image paste and drag-and-drop).
