English is used in communication worldwide by EFL students and their EFL instructors during science learning and teaching. EFL nursing students and instructors are not supposed to be different from the international setting. However, it was observed that this was not the case for both instructors and students enrolled in the two-grade Ismailia Technical Health Institute and the mother tongue, Arabic, not English, was used considerably. The aim of this study was to unveil the aspects of the problem, including time when Arabic was used, causes of the problem, exact percentages of English and Arabic used in communication, existing barriers to communication in English, and recommendations for intervention. The study involved two-year two majors, namely Medical Laboratories and General Nursing, covering the communication languages used in all subject areas. The study adopted a qualitative approach conducting two separate semi-structured interviews with the same set of questions for both students and their instructors. The findings indicated that the majority of instructors of the two-year two majors used Arabic because they quite mistakably assumed their students had a low proficiency level of English. The findings also revealed that the percentage of English used in communication was remarkably low (10% to 30%)). Recommendations offered by both students and instructors included adding a course for oral communication, and students saw that the time for the English subject be increased. They further suggested instructors should allow students time to express their views and engage them in discussions, debates, interactions, motivate them to use the language
