The acquisition of foreign language vocabulary: Does spacing effect matter?
Open accessAbstract
Introduction. Research that investigated effective strategies for learning foreign language vocabulary revealed that long spacing facilitates learning more than short or no spacing. This phenomenon is known as distributed practice effect. Aim. The present study aimed to examine the effect of spaced instruction on vocabulary learning and retention among Saudi EFL learners. Methodology and research methods. The sample of this study includes 30 English major students at King Khalid University. The students were divided into two groups (15 students for the massed instruction group and 15 students for the spaced instruction group). Both groups were taught 20 new words which were selected based on the results of the Vocabulary Size Test by Nation P., Beglar D. In the condition of massed class, the target words were taught in 45-minute weekly session (lasted for two weeks). In the condition of spaced class, 45 minutes were distributed into three 15-minutes session presented throughout the week at intervals with two intervening days between each session (lasted for two weeks). Both groups received a post-test after eight weeks of training, while the delayed post-test was administered three weeks later (week 11). Results. The results of the study revealed that there was statistically significant difference between the massed and spaced instruction groups on both post-test and delayed post-test in favor to the spaced instruction group. Scientific novelty. The present study makes several contributions to the body of literature. First, it adds to the relatively small amount of research on the spacing effect on the acquisition of foreign language vocabulary. Second, it is one of the very few studies that have been conducted in the Arab world, more specifically in the Saudi context. Finally, the study provides better understanding of the importance of spacing in learning foreign language vocabulary among Arab learners. Practical significance. In the light of the obtained results, several recommendations have been provided for EFL practitioners and curriculum designers. This study suggests that EFL practitioners should consider spaced learning as beneficial teaching strategy, and to synthesise it in the educational materials.

Spaced learning is an effective study alternative that improves memory when learning episodes are distributed over time rather than concentrated in a single session.
“In contrast, Al-Khasawneh (2023), Kim and Webb (2022) and Walsh et al. (2023) point to spaced learning as an effective study alternative that improves memory when learning episodes are distributed over time rather than concentrated in a single session.”

“…2015); this pattern is documented predominantly within non-declarative, procedural motor skill acquisition (Khalafi et al., 2024), whereas explicit conceptual and lexical mastery demonstrates superior consolidation via longer, expanding multi-day schedules (Vagha et al., 2025; Al-Khasawneh, 2023).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
