Résumé:
Students are facing different problems that may disturb their learning such as the lack of
appropriate vocabulary use, misunderstanding grammar rules, and the difficulties in language skills;
listening, speaking, writing and reading. Hence, using the appropriate materials by teachers would
be the useful solution to overcome them. The present study attempts to investigate the suitability
and effectiveness of ESP materials selection in enhancing computing science students’ level of
comprehension. The obtained results by means of questionnaires to (02) CS teachers and (30) first
year CS students reveal that appropriate ESP materials selection cannot be done in a good way
unless it respects five specific criteria: appropriacy, accuracy, range, flexibility and size. Following
these criteria is very helpful but the need to respect factors such as time constraints, learners’ age,
sex, level, and background knowledge is also crucial. The results also show that the availabity of
ESP materials and administrative facilities have a big impact on enhancing students’ level.
