Visualizing student errors

One of my projects involves using visual representations for scaffolding learning. I’ve been trying to model a variety of common errors reported by teachers and in prior studies. Would presenting errors to students facilitate deeper conceptual learning? What is the best way to present these? As contrasting cases? Any thoughts and feedback are welcomed!
