“…In the survey, teachers were asked to indicate their age (1 = 20-25 years, 2 = 26-30 years, 3 = 31-35 years, 4 = 36-40 years,5 = 41-45 years, 6 = 46-50 years, 7 = 51-55 years, 8 = older than 55). These age categories were first recoded into three categories that are in line with generational cohorts that can be found in the literature under the labels of Generation Y, Generation X, and the Baby Boomers generation (young = 20-35 years, middle = 36-50 years, old = 51 and older) (Edge, 2014;Geeraerts et al, 2016;Glass, 2007;Novotný & Brücknerová, 2014). Consequently, this categorical variable contains three categories that each cover approximately 15 years.…”
