This study investigated the effects of equal spacing, expanding spacing, and massed condition on L2 receptive and productive vocabulary retrieval. The participants were 63 pre-intermediate FL learners randomly divided into one control and two experimental groups. Initially, a teacher-made Vocabulary Knowledge Scale (VKS) was used to select 20 unknown word pairs (each word accompanied by a synonym). The 20 target word pairs were later divided into two A and B 10-item sets. During the treatment, the target items were studied under an equally spaced condition (2-2-2), an expanding spaced condition (0-1-5), and the no-spacing or massed condition (0-0-0). At the end of the experiment, the same VKS was used as a post-test to check the effects of the treatments. The results indicated that introducing spacing had
enhanced both receptive and productive vocabulary learning with equally spaced schedule being the superior condition.
