What are interactive lessons on CLASSQR?

In CLASSQR, every class has a Content tab made up of lessons. A lesson is a sequence of activities in teaching order: present slides, watch a video, play a quiz, hand in 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.

Clicking + on a lesson (Add activity) offers nine activity types: Assignments, Quiz, Test, Slide, Document, Video, Link, Content and Simulation. The main ones:

Slide · Document

Upload PowerPoint, Word or PDF and view it on the web; between PowerPoint slides you can insert a YouTube video or a simulation.

Video · Link

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

Content

Reading or notes in a full editor: formatted text, tables, images and math.

Quiz

A live question-and-answer game in class; students join with a QR code. The questions come from a file you import or a test in your library.

Assignments · Test

An assignment collects a written answer, a file, a voice recording or a test by a deadline; a test is a timed exam with a passing score and attempt limits.

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

First: create the class

Go to Classes → Create. First pick a grade level and subject (they drive the question bank filters later). Then fill in the Name, an Online class link if you teach over Zoom or Google Meet, turn on Allow open registration via link/QR so students can join on their own, and set the Study format, the Billing method and the Amount. Once saved, the class page has the tabs Class feed · Content · Students · Sessions · Result · Messages.

A center running several classes on the same curriculum builds it once in Library → Curricula, then brings it into each class with Other → Import from course in the Content tab. A curriculum is a “template class”: it has lessons and activities but no students.

Building a lesson step by step

  1. Add a lesson. In the Content tab, click Add lesson and name it after the textbook section (“Lesson 12: Ohm’s Law”); Paste in that dialog creates several lessons from a list you copied. Lesson groups gathers lessons into units.
  2. Open with slides or a video. Click + on the lesson (Add activity), choose Slide, then Upload a PowerPoint or PDF 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 or simulation between two slides. In the viewer of a PowerPoint deck, each thumbnail has buttons for Insert YouTube video after this slide and Choose a simulation; the trash button (Remove embedded item) takes the insertion out again. Only teachers who can edit the class see these buttons. A PDF opens in a plain PDF viewer without them.
  4. Reinforce with a quiz. Choose Quiz, then import a file or Select a test from your library — for example one you made with AI. In class, open the quiz: questions show 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 them with a camera.
  5. Assign homework. Choose Assignments: Name, what is Required (Submit text, Submit file, Recording or Take exam, which lets you pick a test and set Attempts and View exam results), the Deadline, Instructions, an optional simulation, and the Rubric. Multiple-choice work is scored the moment it is submitted.
  6. Schedule a formal test. Choose Test, then Choose from library to pick the test paper, and set the Name, Exam type, Maximum score, Passing score, Rounding, what is Shown after submitting, Attempts, Timing, Late entry and Leaving the exam screen. The Security & proctoring section adds a Password and Full screen required.

The Content activity

The Content activity is a full editor for reading material or notes: formatted text, tables, images and math formulas. Use it for a summary at the end of a lesson, worked examples, or instructions students read on their own.

What does the student see?

  • They join the class with a link or QR code the teacher shares (Invite students in the class header, with Download poster 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 lists the lessons in order and shows only the activities shared with them; a Lesson activity is meant to be used together in class, a Homework activity has a deadline.
  • Video and quiz activities run right in the phone browser, with full touch support.
  • A teacher tracks each student in Result → Gradebook: the score for each assignment and test, plus bonus points.
  • Teaching online: students open the class’s Zoom, Google Meet or Teams room with Join now. With Zoom connected, ClassQR can create the room for you and suggest attendance after class.

Reusing and sharing lessons

  • Save as a curriculum: Other → Save to materials in the Content tab stores every lesson and activity of the class as a curriculum (it then appears in Library → Curricula); saving under an existing name asks before overwriting it.
  • Bring a curriculum into a class: Other → Import from course, pick the curriculum and tick the lessons to bring in. A center with several branches only has to build content once.
  • Many lessons at once: in Add lesson, Paste turns a list of lesson names copied from a syllabus (one per line) into lessons.
  • 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, Word or PDF file as a Slide or Document activity; the system builds a web viewer for it. In a PowerPoint deck you can insert a YouTube video or a simulation 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 lesson in another class?

Yes. In the Content tab, Other → Save to materials stores the whole class (every lesson and activity) as a curriculum; in another class, Other → Import from course brings in the lessons you tick.

How are essay assignments scored?

Multiple choice, true/false, and fill-in-the-blank questions are scored against the answer key with fixed rules. Essay assignments are marked by the teacher against the stated criteria.

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 and attempt limits.
