Building Capacity for Teacher Training

ECS4Alabama is increasing capacity to provide ECS training from within the ECS4Alabama teacher community. To-date, two Alabama teachers from the ECS4Alabama project have emerged as a trained facilitator (Ms. Tangela Crocker and Mr. Darryl Callen). Three other Alabama teachers are gaining readiness and need another year to be fully certified. In the context of inclusion and diversity in CS, the two trained facilitators and two of the three facilitators in preparation are African American educators.
