This article is based on a survey carried out at Imperial College, to understand better needs, problems, advantages/disadvantages and solutions in the use of new technologies in a specific context, such as engineering education. In comparison with other research on this matter, perceptions, benefits and barriers to using computer-assisted learning and information and communication technologies in higher education, the present study reveals something more about the use of educational technologies in scientific subjects: many lecturers believe that technical subjects do appear to benefit greatly from the ability to teach using real-life computer simulations which help with student motivation and understanding. Moreover, the use of computers allows practical experiences and help in data analysis, and often work would be impossible without computers. Nevertheless, the survey results indicate that, although there are many advantages in the use of computers in teaching and learning, there are many difficulties for lecturers in using the new technologies because of logistical problems, such as lack of time, technical support, appropriate software and hardware, etc. There is a need to consider what support can be offered and how, on a national level.
