Immediate feedback for more motivated students and critical thinkers

Classtime is a solution for teachers that complements in-class teaching with immediate feedback on every student’s level of understanding by asking questions and validating answers. Our Collaborative Challenges furthermore enable a teacher to create a narrative around his or her lesson plan that motivates students to work together towards a common goal.

Formative Assessment: Improving Learning for Every Child

January 2022
Classtime is a lifesaver. I love the fact that I have the opportunity to create assessments, lessons and fun activities for my students in a reasonable amount of time. It's easy and student friendly

About the innovation

Why did you create this innovation?

The classroom experience is core to the education path of every child, yet classroom learning delivers massively below potential. In many classrooms we observe kids are not engaged enough, not everybody participates, learning is not actively applied. We believe that technology can play a strong role in addressing these issues, by introducing fun yet competency oriented formative assessments.

What does your innovation look like in practice?

Teachers create their own questions, collaborate on question banks, or import public or curated question banks from other teachers or publishers. They activate question sets tailored to their curriculum as sessions for the students. Sessions can come in various forms, e.g., classic formative assessments, pre-knowledge checks, exit tickets, homework, self-study or autonomous learning, digital exams, and more exotic use cases like collaborative games, digital escape rooms, sessions fostering discussion and debate, journaling, etc. Students then solve the sessions on their own devices or on a shared device. The results are generated in real-time and can be made available to the students. Teachers obtain a diagnostic on the learning progress of students in real time and can adapt their teaching to the level of understanding of the class.

How has it been spreading?

Classtime has reached 10,000,000 students and registered 170,000 teachers across more than 50 countries so far. The goals for the next 2 to 3 years include further improving the product by incorporating more detailed feedback (rubrics, more possibilities of free text), building content partnerships, and continuing to scale up, implementing the solution to numerous federal states in Germany, districts in the US, deepening the reach in Europe and other countries.

Implementation steps

Start a Session from your Library
The Library is where you can create, edit and manage all of your Questions into Question Sets.

When you visit the Library for the first time, you will find a few example Question Sets that have been prepared by us. You do not need to be registered - go take a look:

Before we go into the creation of your own Questions and Question Sets, we suggest to experience how a real session might look like!

Simply click on "Start Session" within the selected Question Set.

Simulate a real Session

See how it would look like before you apply Classtime in a real-life, class setting!

Once you click on 'Start Session', a new live Session will be activated and you will be automatically forwarded to the Session Dashboard.

On the Session Dashboard, you can find the Session Code, manage your Questions, and see your students' answers.

Session Code

Every Session automatically generates a unique Session code that can be shared with your students to join during class. This can be done in two ways: either copy and share the URL, or ask your students to go to and enter their code in the prominently visible 'Students' field. If you have a Class set up, you can directly invite them via email.

Session Questions

All Questions can be individually shown and hidden from the student devices, giving you great flexibility to tailor and time them based on your teaching. This is quickly done by clicking on one of the toggles on the right side.

Student Answers

This is where you will be able to see all the student answers appear in real-time, giving you the ability to quickly assess the learning progress and engagement of your class. Within a few seconds, you will be able to better understand how to adapt your class teaching to maximize overall learning progress.

The easiest way to see how this works is by clicking on 'Start Preview' at the bottom of the page.

Once the simulation starts, you will get a better feeling how a real class might look like. Clicking on any answer cell of a student will show you more information about their answer.
