“…Agricultural mechanics knowledge issues are compounded by a lack of adequate training, professional development, and instructional materials in agricultural safety (Rudolphi & Retallick, 2015). Specifically, agricultural programs have reduced the amount of training received in courses specific to agricultural mechanics (Burris et al, 2005;Schumacher, Ess, Strickland, & King, 2002), and teachers across multiple geographic regions and teaching experience levels have reported a need for professional development related to agricultural mechanics (Blackburn, Robinson, & Field, 2015;Duncan, Ricketts, Peake, & Uesseler, 2006;Stripling et al, 2014). Among the many professional development needs of agricultural mechanics teachers, safety instruction and supervision is a top concern while in the agricultural mechanics laboratory (Gliem & Miller, 1993;Johnson & Schumacher, 1988;Langley & Kitchel, 2013;Swan, 1992).…”
