A learner behavioral anslysis on the effectiveness of scaffoldings for language learning with educational robots and IoT-based tangible objects

The integration of educational robots and IoT-based tangible objects (R&T system) holds great potential for enhancing the learning outcome and providing scaffoldings for language learners. This study was focused on examining the learners' behaviors during language learning activities, to analyze the effectiveness of the scaffoldings provided by the R&T system. The aim was to assess the task completion and responsiveness to learners' learning states. A method called Lag sequential analysis was employed to identify significant sequential behavioral patterns. The results showed that, in addition to confirming the effectiveness of the scaffoldings, the sequential pattern analysis was useful in capturing the dynamics of interaction among learners, robots, teachers, and peers in real-life learning scenarios.
