Abstract
The main goal of this research is to systemize, build, and test prototype software to demonstrate Indirect Spaced Repetition (ISR) as a viable concept for Second Language Vocabulary Acquisition (SLVA). ISR is designed around well-founded spaced repetition and SLVA principles. Most importantly, it is based on Nation’s (2001) recommendation to consider all three tiers of word knowledge (meaning, form, and function/use) and subsequent 18 aspects of word knowledge for a more balanced approach in teaching and learning vocabulary. ISR prototype software was achieved in the conceptual phase of the research. The resulting prototype flashcard software was given an in-depth trial for a period of 2 weeks by seven university students. Participants were given a post-project survey to evaluate ISR software (ISRS) under four categories: enjoyment, usefulness, usability, and general consideration. Post-test survey findings showed above-average satisfaction and consideration to use such software in the future. However, these findings also revealed that some areas could be further improved, such as addressing some hardware/software issues (e.g., IT infrastructure problematics and lag) and integrating gamification elements (e.g., performance feedback/reports).
