I intentionally did not set any ground rules when demonstrating how to use Padlet and although the trainees were adults, they very quickly ascertained that amusing comments could be posted, to the delight of their peers. This indicated a natural curiosity amongst the group and is a value that I would encourage when using technology. However, this does have professional implications when it is being used in a school setting, which the trainee teachers recognised. This experiential learning provided a powerful experience for them as they could immediately see one of the pitfalls of using the technology in a school classroom. I was then able to model that it is possible to moderate the messages before they are visible online enabling the teacher to delete any inappropriate content.
