The Impact of Spaced Learning Strategies on Vocabulary Retention in Primary English Classrooms

Vocabulary knowledge is a cornerstone of language proficiency, yet the retention of new words remains a persistent challenge for young learners of English as a foreign language. Traditional approaches in primary classrooms often rely on repetition within single lessons or short units, which may lead to rapid forgetting. This article explores the impact of spaced learning strategies, also known as distributed practice, on vocabulary retention in primary English classrooms. By reviewing key empirical studies, including large-scale meta-analyses and controlled classroom experiments, the paper highlights consistent evidence that spacing practice sessions over time produces stronger long-term memory than massed practice. Cognitive explanations for this effect include repeated retrieval, reconsolidation of memory traces, and increased attentional engagement when exposure is distributed. The introduction outlines the centrality of vocabulary in early foreign language learning, with reference to the Spanish primary context where exposure to English is limited to classroom time. The article then discusses how spaced practice can be integrated into everyday instruction, including lesson sequencing, homework routines, and the use of digital tools such as flashcard apps. Results from studies with young learners suggest that modest changes in practice distribution can yield significant improvements in vocabulary retention without requiring additional teaching time. The discussion considers practical challenges, such as curriculum pacing and teacher training, while emphasising that implementing the accessibility of spaced learning for primary classrooms. The article concludes that embedding spacing principles into English language teaching represents a cost-effective, evidence-based approach to strengthening vocabulary learning outcomes in primary education.
