Within the framework of a research aiming at measuring the impact of the use of Information and Communication Technologies (ICT) in scientific higher education, we carried out a study with 108 students (40 men and 68 women) coming from various establishments of scientific higher education. The objective of this study is double. It will allow on the one hand, to determine the perceptions of these students towards the use of the ICT during the session of course and practical works (PW); in addition, to identify the most appreciable teaching mode (traditional, integrating the ICT or hybrid) for a better learning of sciences within the university. The results of our investigation show that the integration of ICT in scientific courses and PW is beneficial for the majority of the students and can improve the quality of their learning. However, to help the students in difficulty and to bring more effectiveness during the sessions of teaching, these tools should be used in appropriate techno teaching situations where other teaching materials are also exploited.
