Slides are material that supports the information expressed by a speaker. Slides have increased their importance in education due to the multimedia information that we can represent in them and their easy access. Most conference or class presentations do not engage participants in an adequate way. Therefore, this research aims to develop a presentation and survey system in a real-time web application that allows interaction between the teacher-lecturer and the audience in an active way during the session. This research evaluated the system from three approaches: usability, acquired knowledge and user experience. The results suggested that SlideCheck could be an excellent option to encourage students to participate during classes, improve knowledge acquisition and improve interaction with the teacher during the session, making the lesson more dynamic.
