Abstract
Motivation is widely recognized as a key factor, in second language learning, especially in supporting learners’ ability to retain grammatical knowledge over time. In the context of English as a Foreign Language (EFL), it influences not only how students engage with learning materials but also how effectively they store and recall grammatical structures. This study explores, how both intrinsic motivation, which arises from personal interest, and extrinsic motivation, which is driven by external rewards, affect Iraqi university students’ retention of English grammar.
To examine this relationship, the research employs a quantitative method, using a quasi-experimental design. Two groups of students participated in the study: an experimental group exposed to motivational teaching strategies and a control group taught through conventional methods. The purpose of this design was to compare the outcomes of motivated and less-motivated learners in a controlled academic setting.
Data collection was carried out through a series of assessments, including pre-tests to determine initial proficiency, post-tests to evaluate immediate learning outcomes, and delayed tests to measure long-term retention. This multi-stage assessment approach allowed the researcher to track changes in students’ grammatical knowledge over time and to assess the durability of learning.
The results demonstrate a clear advantage, for students who were exposed to motivational strategies. These learners showed higher levels of achievement not only in immediate post-test performance but also in delayed assessments, indicating stronger retention of grammatical concepts. In contrast, students in the control group exhibited lower levels of retention, suggesting that traditional teaching methods may not sufficiently support long-term learning.
Based on these findings, the study conclude,s that motivation is a significant factor influencing the retention of grammatical knowledge. It highlights the importance of incorporating motivational techniques into EFL instruction to enhance both learning outcomes and long-term retention. Accordingly, educators are encouraged to adopt teaching practices that foster student motivation, as this can lead to more effective and sustainable language learning.
