In line with constructivist educational theory and the theoretical work on the value of feedback in assessment, a Web application named WEBEXDE (WEb-Based EXamination Device) has been developed. The application allows the teacher to question students during seminar and to detect through their answers the level of their former knowledge and the level of understanding and ability to follow the seminar topics. It is also an attempt to motivate students by means of formative assessment to actively participate during seminars of Physics course. The application also allows performing a short quiz during laboratory practice in order to check the required knowledge, i.e., to check whether a student has acquired the knowledge necessary for a specific exercise. At the end of the course, a survey was conducted questioning students’ self-perceived interaction with the teacher, motivation, self-assessment of general competencies acquired, satisfaction, ICT literacy and some general guidance for the improvement of the Web application.
