Table 3 proves that there was a significant difference between the results of the control group and the experimental
group, as the (t) value was 2.25, which is statistically significant at α < 0.05. This is lower than the set criterion where
the hypothesis will be rejected if p≤0.05. Therefore, from Table 3, the second null hypothesis is rejected and the first
research question is answered , concluding that there is a significant difference in vocabulary competence between
learners taught with role-play and those taught by the traditional method in favour of the experimental group, because
its mean is higher than that of the control group. Moreover, Table 3 shows the difference was statistically significant (t=
1.102, p= 0.03). Therefore, the null hypothesis is rejected.

ONCLUSION
The previous statistical analyses achieve the main purpose of the present study which was to investigate the effects of
using role-play strategy on secondary school students' vocabulary achievement. The mean value of the experimental
group observed (36.0) was greater than the mean for the control group (32.6). This indicates that the experimental group
showed a significant advantage over the control group with regard to the scores gained in the post-test. In other words,
the results are in favour of using role-play strategy in teaching words. This means that using a role-play strategy in EFL
classes is worthwhile, and more effective than using the traditional vocabulary teaching. This finding is consistent with
the results of previous studies showing that role-play is an effective strategy for enhancing student vocabulary
achievement in specific and in learning English language in general (Toumpaniari, et al., 2015; Ernandez et al.,1992;
Umbel, 1992; and Allman, 2005; Sadeghi & Sharifi, 2013; Nair et al., 2014). The reason for the great development in
vocabulary achievements of the experimental group is that the role-play strategy is far more pleasant and engaging than
the traditional method, which is conducive to highly motivated students and a more creative learning environment
(Piaget, 1972; Vincent & Shepherd, 1998; Sasaki, 1998; Clemens,1998; Huang and Shan, 2008; Liu & Ding, 2009; and
Aliakbari and Jamalvandi, 2010) and also consistent with most recent studies , such as Altun (2015), Afdillah (2015),
and Kuipers & Clemens, (1998).
The main question for the current study asked whether there would be a significant difference between the pre- test
and post- test for the control group, taught in the traditional way. Findings showed that there was no significant
difference between them. This result revealed that the traditional method was ineffective in teaching vocabulary, which
may be because students were bored in learning English vocabulary due to the old teaching method. Therefore, the
evidence supports the use of role-play as an effective strategy in teaching, to have the best results in learning.
As mentioned before, this study was designed to empirically investigate the effects of ‘Role Play’ as a strategy for
teaching vocabulary and whether it can increase EFL learners’ lexical ability. Adopting this technique and running the
procedures for a period of four weeks yielded remarkable outcomes. Moreover, during lessons pupils enjoy learning and
the learning experience becomes more pleasant, entertaining, and full of fun. According to the results, the participants in
the experimental group achieved better than those in the control group. In other words, through the results derived from
the study, role-play, recommended by many experts in the field, was practically shown to be an effective and successful
activity school student, to be used in English lessons among Saudi secondary school students.
Based on the results of the study, the researcher suggests the following recommendations:
1. Teachers should apply role-play strategy in teaching vocabulary.
2. EFL learners should be encouraged to use role-play to enhance their vocabulary proficiency.
3. EFL syllabus developers are advised to integrate the use role-play in the English curriculum.
4. Training courses should be provided for EFL teachers to give them practice on the use of role-play strategy in the
learning process.
It is recommended to conduct similar studies that investigate the following.
1. Researchers should apply further studies to explore the effect of role-play strategy on other English skills.
2. Students' and teachers' attitudes toward using role-play strategy in learning English lesson could be investigated.

3. The effects of role-play strategy not only on language proficiency but also other variables, such as motivation for
learning the target language, should be explored.
4. Further research can be conducted to evaluate existing EFL teachers' training programmes in Saudi Arabia toward
using role-play strategy.
