Résumé:
The present research sheds some light on the process of learning of English as a foreign language in Algeria. It covers, mainly the many factors that affect learning, either directly or indirectly. Thus, the overall aim of this study is to investigate the internal and external factors affecting English learners’ achievements. More specifically, the study seeks to identify their learning problems and to explore their attitudes towards the importance of effective teaching strategies in achieving goals. Thus, it is hypothesized that there is a number of factors that influence learners’ achievement in EFL learning. We expect that those factors either encourage or hinder learners’ success. This research has been conducted under a descriptive method. In order to gather data, we have administrated a questionnaire to twenty-one master two students of English at Mostaganem University. The second tool was an interview administrated to ten selected students who belong to the same group. Furthermore, the results of the research findings show that the impact of internal and external factors on EFL learners’ success is highly significant. These factors are self-esteem, the influence of mother tongue, anxiety, attitude, gender, motivation, interaction, and culture. Based on the obtained results, the previously stated hypotheses were confirmed.
