As an 8th grade History teacher, Millers engages his students with hands on activities such as historical court case reenactments, or encouraging students to adopt the persona of a historical figure. Sierra Vista began participating in the National History Day Contest as an extracurricular activity. However, after seeing its effectiveness to improve student skills in research, use of technology, reading, and writing, it was decided to expand the program. It is now a key component in the school curriculum. The annual school presentation of these projects draws more than 300 attendees, including former students who offer advice to the next generation of National History Day Contest participants.
