Possible uses

Taking into account time constraints, number of participants, teaching and learning objectives, course content or levels of competence that influence the use of CRS, there are numerous possible uses, such as:

  • Summative or formative assessment
  • Asking comprehension, review and application questions
  • Preparing and initiating discussions
  • Conducting peer instruction
  • Facilitating mutual anonymous assessment
  • Asking feedback questions on own teaching
  • Event management
  • Encouraging group work


The benefits of Classroom Response Systems (CRS) include:

  • Overcoming student inhibitions: The use of CRS can help overcome the inhibitions of students who are normally reluctant to participate by speaking in public.
  • Quick and easy polling and questioning: CRSs allow students to easily participate in polls and answer prepared questions. This not only encourages their active participation, but also enables efficient interaction during the seminar.
  • Anonymous participation for active contributions: Anonymous participation encourages students to freely express their thoughts and opinions without fear of repercussions. This encourages them to participate more in discussions and to make high quality contributions.
  • Using the results to improve the quality of teaching: Thinking in advance about how teachers can use the results of the CRS adds value. The data can be used to adjust the teaching process, to better understand students' difficulties and to develop more effective learning strategies overall.
  • Encouraging engagement with learning content: By answering questions and participating in surveys, students are encouraged to engage more deeply with course content and deepen their understanding.
  • Stimulating discussions: As well as facilitating dialogue between students and teachers, CRSs encourage discussion and interaction between students themselves. This contributes to a lively learning environment where different perspectives can be shared.
  • Ideal for large events: CRSs are particularly well suited to events with large numbers of participants, as they provide an efficient way of capturing a large number of opinions and responses in real time. This allows for interaction and involvement of all students, even in large groups.

Classroom Response Systems are suitable for implementing the didactic concept of Just-in-Time Teaching (JiTT). Teachers use interaction with learners to adapt course content and teaching strategies in real time. This is more likely to meet learners' needs and understanding, rather than strictly following a curriculum. Just in time teaching encourages active participation in the learning process. Learners are encouraged to ask questions, lead discussions and actively participate in shaping the seminar. More information on the design of JiTT is summarised on this website of the University of Bern.


Particify is available at Leuphana University. Particify is a browser-based and DSGVO-compliant classroom response system. It offers key functionalities such as live Q&A and live feedback as well as different types of quizzes and surveys for interaction between teachers and students.

Surveys and live feedback from Particify can be quickly and easily shared with external participants via a link or QR code. For more information, please visit the Teaching Service website​​​​​​​.

Surveys in Zoom

The Zoom videoconferencing tool also allows you to encourage interaction through polls and quizzes. This is limited to the videoconference participants and cannot be shared. The procedure is described on the manufacturer's website.
