Micro-credentialing is a useful and meaningful method of displaying a person's skill and knowledge. This platform is a wonderful way of meeting the needs of adult learners. Badging allows individuals to advance and provide evidence of educational growth at their pace.
As a professional developer, I see how badges would be beneficial for participants. As teachers learn a new strategy they could post documents of their learning, implementation, and the impact of strategy instruction. A badge could serve as an artifact in a teaching portfolio, evidence of competence in the use of a strategy for a resume, etc.
