“…Teachers viewed a lack of time (e.g., short classes), little space (e.g., small gyms), limited institutional support (e.g., lack of funds), and minimal student interest (e.g., students not motivated) as barriers to their ability to teach physically active lessons. These themes were not unexpected, as researchers, operating from a variety of theoretical perspectives, have found that similar variables impair effective teaching, reduce confidence, and create worry and stress (Boggess, Griffey, & Housner, 1986;Chester & Beaudin, 1996;Guskey & Passaro, 1994;Hastie & Saunders, 1991;Hoy & Woolfolk, 1993;McBride, 1993;Ross, 1994;Smyth, 1995;Stroot, Collier, O'Sullivan, & England, 1994;Wendt & Bain, 1983).…”
