Classroom Without Walls
课程、教材与直播课堂
连成一套学习中心
Courses, materials and live class
in one student centre
Linguolab 在线学习把校内学术路径搬到学生中心：登录后查看下一节课、下载本班教材、在开课窗口进入腾讯会议。视频不经过本站，教材也不放在公开目录。
Online Learning brings the Linguolab academic path into a student centre: see the next class, download materials for your courses, and join Tencent Meeting in the class window. Video never runs through this site, and files are never left in a public folder.
直播课堂 Live Classroom
每一节课单独排期。开课前 30 分钟入口开放，学生点击「进入直播课堂」，由后台核验后转到腾讯会议。会议链接不会写在公开页面里。 Each lesson is its own session. The door opens 30 minutes before class. Students tap Enter Live Classroom; the server checks access, then redirects to Tencent Meeting. The meeting URL is never published in the page source.
课程教材 Course Materials
PDF、课件与录音存放在网站根目录之外。下载必须登录，并且只开放给学生已选的课程。同一份教材可被多门课引用，不必重复上传。 PDFs, slides and audio live outside the web root. Downloads require a signed-in, enrolled student. The same file can be linked to several courses without being stored twice.
学生中心 Student Centre
打开学习中心即可看到下一节课、我的课程和新教材。教师在后台上传资料后，学生立即可见。管理员负责开课与选课。 The centre opens on the next class, your courses, and new materials. When a teacher uploads a worksheet, students see it at once. Administrators create courses and enrolments.
四步进入课堂 Four steps into class
1. Login
使用学校发放的账号登录。会话写在 HttpOnly Cookie 里，页面脚本读不到登录凭证。 Sign in with the account Linguolab issues. The session lives in an HttpOnly cookie, so page scripts cannot read the credential.
2. Dashboard
首页显示下一节课的时间、教师与进入按钮，并列出本学期课程进度。 The home screen shows the next class, the teacher, the join button, and progress across the term.
3. Materials
在自己的课程里下载 Reading Worksheet、词汇表或学生用书。未选课无法打开文件。 Download the reading worksheet, vocabulary list or student book for your own courses. Files stay closed without enrolment.
4. Join
开课窗口内点击进入直播课堂，跳转到腾讯会议。摄像头、麦克风和屏幕共享都在会议里完成。 In the class window, enter the live classroom and continue in Tencent Meeting. Camera, microphone and screen share stay on their side.
