A South Florida school district studied discipline referral rates from August 1997 to April 1998. From the 4,391 referrals from grades K-12 they found that males they accounted for 80.5% of all rule violations (McFadden, A.C., Marsh, G.E., Price, B.J., & Hwang, Y.. 1992). Another study conducted across 92 departments at the University of Wisconsin-Madison examined how teachers' education on gender bias impacted their teaching. The school offered departments 2.5-hour gender bias intervention workshops, and when follow-up models showed there were greater changes after attending the workshop. An important increase occurred with teachers who achieved such self-efficacy that they were aware of creating gender equality in the classroom (Carnes, M., Devine, P.G., Manwell, L.B., Byars-Winston, A., Fine, E ., Ford, C.E., ... and Sheridan, J.
