Attendance tells you who came, not who took part. Engagement shows in what people did: how many answered, how many asked, how many got it right, and how that changes from one session to the next. Diaposi writes it down for you, in a report slide by slide after every session and one view across all of them.
What does engagement look like in numbers?
Attendance counts chairs. Engagement shows in what people did while they sat in them, and three simple measures capture most of it. None of them needs special equipment, only that the room answers through a channel that keeps count.
Which measures are worth taking?
- Participation rate. Answers received divided by people present, for each poll. It shows whether the whole room is with you or only a part of it.
- Question volume. How many questions came in, and at which slides. A slide with many questions is a slide to rework.
- Answer spread. For a question with one right answer, the share that got it. A split result marks an idea that did not land.
What should a session report show?
The same three measures, slide by slide, so you can see where the session held and where it dropped. One session tells you little. The useful view is across sessions: the same course over a term, compared with the weeks before. Be careful with single numbers. A quiet room during a hard derivation is not a disengaged one.
For acting on the measures during the session itself, see how to collect real-time feedback during a lecture. For the reasons behind them, see what active learning is and why it works.
How Diaposi measures a session

Diaposi writes these down for you. After every session you run with your account, a report shows attention slide by slide, who took part and where to act next, and it counts quiet signals too, such as going back to reread a slide. Across sessions, one view shows participation, questions and quiz completion over time, compared with the period before. Participants stay anonymous throughout.

Frequently asked questions
Can engagement be measured without identifying people?
- Yes. Counts are enough: how many answered, how many asked, how many got it right. In a Diaposi report, each participant’s activity is numbered by order of arrival, never by name.
Is a high participation rate the same as learning?
- No. Participation shows that people took part, and the share of correct answers shows what they understood. Read the two together.
Is Diaposi free?
- Yes. Diaposi is free, and there is no paid plan today.
