Students' motivation and their English learning achievement were strongly and positively correlated with each other (p=.000<.05). If we want to improve achievement, we should influence motivation, especially with regard to two of the most important motivational factors: learning situational components and group cohesion. The findings could be useful for researchers and teachers in improving students’ achievement by devising effective teaching and learning strategies to increase students’ .
