This study aimed at identifying the effect of a training program in developing the use of learning English language strategies among a sample of the Hashemite University students, and the differences in using these strategies due to gender and the type of group (experimental and control groups). The study sample consisted of 76 male and female students from the Department of English Language, divided into two groups (an experimental group of 34 male and female students and a control group of 42 male and female students). To achieve the aims of the study, Oxford's language learning strategies scale was used. The study used a quasi-experimental research design with pre-test and post-tests. ANCOVA and T-tests were used to analyze the data. The results of the study revealed that there is a statistical significant difference between the two groups in developing language learning strategies in favor of the experimental group. Also, results showed that there is no statistically significant difference in using language learning strategies attributed to gender.
