Effectiveness of Type of Feedback and Frequency on Digital Game-Based L2 Vocabulary Acquisition

The frequency of word exposure in teaching materials, along with corrective feedback, has often been identified as a powerful variable in the learning of vocabulary in a foreign language. The effect of the number of times an action is presented as accurate in digital game-based language learning scenarios (i.e., knowledge of correct response [KCR] feedback) however remains under-investigated. This study aims to analyse the learning of L2 mobile operating system terminology by a group of students of English as a foreign language by using the data collected by the video game The Conference Interpreter in order to identify the predictive strength of term frequency (times a term is shown), KCR feedback (times a correct answer is provided), and corrective feedback (times a term is shown as incorrect) regarding short and long-term L2 vocabulary learning. The regression analysis performed showed that the factor ‘KCR feedback' may be a positive predictor of short-term vocabulary learning, whereas the other factors seemed to have no statistical effect at any significant level.
