The Layered Communication Model (LCM) describes intersubjective development based on eight different communicative behaviors in three consecutive layers. Earlier studies showed that when the model is used an intervention, presence of many LCM increases from before to after intervention. present study aims relate content intervention its effectiveness learn whether and how can be improve communication. 15-minute videos four student-teacher dyads were coded ten-second intervals for absence before, during was divided into two phases: self-assessment video feedback coaching. Intervention described targeted improvement phases. Effectiveness measured by calculating percentage increase between phases effect sizes using a nonoverlap all pairs method. Results second phase (video coaching) most effective terms increasing creating larger sizes. measures decreased follow-up but still higher than at baseline. Furthermore, untargeted behaviors. In conclusion, as tool communication, especially specific are clearly coaching clarify work improving those needs adjustments effectiveness.
