A number of previous international studies have shown that many non-native Spanish speaking students lack sufficient oral communication skills. The aims of the study were twofold: 1) to investigate the possible effects of the Audio-Lingual method in the improvement of oral communication skills and 2) to test the effectiveness of two different teaching methods, i.e. the Audio-Lingual method and the Traditional method. A quantitative study was performed based on two different groups of students. One group worked with the Audio-Lingual method and the other group worked with the Traditional method. After a few lessons with the respective methods, the two groups were given a Fill-in the gap test that consisted of three parts: Greetings, Gender agreement and Number agreement. The test in Greetings and Number agreement showed no significant differences in results between the Audio-Lingual and the Traditional method. On the other hand, the test in Gender agreement showed that the Audio-Lingual method led to a significantly better result compared with the Traditional method. The study also demostrated that the students showed a greater interest in the Audio-Lingual method and this method helped the students to use their Spanish knowledge in other situations as well.
