What are interactive lessons on CLASSQR?

In CLASSQR, every class has a Content tab made up of sessions. A session is a sequence of activities in teaching order: view a slide, watch a video, play a quiz, do an assignment, take a test. Students open the class in a browser and work through each activity in turn; scores and progress are recorded automatically, with nothing to re-enter.

Eight activity types are available when you click Add inside a session:

Slide · Document

Upload PowerPoint, Word, or PDF; view it on the web, and drop videos in between slides.

Video · Link

Paste a video link or a web page; students watch it in the class without leaving the lesson.

Rich content

A full editor: text, images, math notation; an AI button helps draft it.

Quiz

A live question-and-answer game, students join with a QR code; generate the questions with AI in under a minute.

Homework · Test

Assign a test with a due date, attempt limit, and automatic grading; timed tests add a passing score and proctoring.

Every activity can be tagged as a Type: In-class, Homework, or Both. That means the same session doubles as a lesson plan you present in class and self-study material for a student who missed it.

First: create the class

Go to Operations → Classes → Add new. First pick a grade level and subject (these drive the question bank filters and AI suggestions later). Then fill in the class name, an online meeting link if you teach over Zoom or Google Meet, turn on Allow self-enrollment by link/QR so students can join on their own, choose the delivery mode, the tuition billing method, and the amount. Once saved, the class page has the tabs Feed · Content · Students · Sessions · Results · Messages.

A center running several classes on the same curriculum builds it once in Teaching → Curriculum and then Imports from curriculum into each class. A curriculum is a "template class": it has sessions and activities but no students.

Building a session step by step

  1. Add a session. In the Content tab, click Add session and name it after the textbook section ("Lesson 12: Ohm's Law"). Drag to reorder sessions.
  2. Open with a slide or video. Click Add inside the session, choose Slide, and upload a PowerPoint file. The system builds a viewer: a strip of slide thumbnails on the left, the current slide large on the right.
  3. Drop a video between two slides. In the viewer, hover a thumbnail and click Insert video after this slide. The insertion is saved with the document itself, so it survives if you replace the file; click Remove insertion to take it out. Only teachers with edit access to the class see these controls.
  4. Reinforce with a Quiz. Choose Quiz → Generate quiz with AI: enter the question count, subject, grade, topic, and a description (or upload a document for the AI to draw questions from). You can also import a file or pick an existing test. In class, click play: questions display on-screen, students scan a QR code with their phone to answer, and a leaderboard appears after each question. For a class without phones, print answer cards; students hold them up and the teacher scans with a camera.
  5. Assign homework. Choose Homework: name, instructions, due date, pick a test (from the Tests list) or just assign an essay prompt, attempt limit, how results are shown (total score, per-question detail, with or without the answer key), and the grading rubric for essay parts. Multiple-choice work grades the moment it's submitted.
  6. Schedule a formal test. Choose Test: pick a test, timing (flexible per student, fixed start, or fully fixed), max score, passing score, rounding, attempt limit, whether leaving the exam screen is allowed, and late entry. The Advanced section has an exam-room password, camera monitoring, AI face verification, full-screen enforcement, and letting the teacher view the exam screen.

The Rich Content activity and AI help

The Rich Content activity is a full editor: formatted text, tables, images, math notation (LaTeX inside $…$, rendered with MathJax). An AI button on the toolbar writes an explanation, summarizes the lesson, drafts discussion questions, and inserts an illustration at the cursor.

What does the student see?

  • They join the class with a link or QR code the teacher shares (Students tab → Invite link, with a poster download to print for the classroom). Anyone without an account is prompted to sign up and lands straight in the class.
  • A student's class page shows sessions in order; an In-class activity is meant to be viewed together, a Homework activity has a due date and reminders.
  • Video and quiz activities run right in the phone browser, with full touch support.
  • A teacher tracks each student in Results → Gradebook: score per assignment, accuracy by topic; click a student to see their activity in detail.

Reusing and sharing lessons

  • Save as curriculum: the More → Save as curriculum button stores every session and activity of a class as a curriculum, overwriting a previous one with the same name.
  • Import from curriculum: a new class picks a curriculum and checks off which sessions to pull in. A center with several branches only has to build content once.
  • Copy and paste an activity between sessions or between classes using the copy button on an activity and Paste copied item.
  • Lessons, tests, and materials you create belong to you and your center; no one outside the class can see them. See content ownership policy.

Frequently asked questions

I already have a PowerPoint deck — do I have to rebuild it?

No. Upload the PowerPoint or Word file as a Slide or Document activity; the system builds a web viewer for it. To add interaction, drop a video right after the slide that needs it, without touching the original file.

Do students need to install an app?

No. Students join a class through a link or QR code and learn and complete work in the browser on a phone, tablet, or computer. Parents don't need to install anything to receive reports either.

Can I reuse a session in another class?

Yes. Click Save as curriculum to store an entire class (every session and activity) as a curriculum; a new class clicks Import from curriculum to pull in the content. You can also copy and paste individual activities between sessions.

Can an essay assignment be graded automatically?

Multiple choice, true/false, and fill-in-the-blank questions grade automatically. Essay assignments are graded by the teacher against the stated criteria, or by AI using that same rubric (billed per assignment in credits); grades from AI grading can still be adjusted.

What's the difference between a Quiz and a Test?

A quiz is a live in-class game: the teacher displays questions, students answer on their phone or hold up a paper card, and there's a live leaderboard. A test is a timed, formal assessment with a passing score, attempt limits, and proctoring options.
