Shaping learners into critical thinkers.


location_on Switzerland
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.
Cristina H., teacher
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.

How does your innovation work in practice?

Teachers create own questions, collaborate on question banks, or import public / 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 / autonomous learning, digital exams, and more exotic use cases like collaborative games (see bold blog:, digital escape rooms, sessions fostering discussion / 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. The teacher has her diagnostic of the learning progress in real time and can adapt her teaching to the level of understanding of the class.
