I strongly believe all successful teachers have the ability to be “elastic and fluid” within their classrooms as there are always unexpected distractions and delays. As for CTAE teachers, they must be a degree or two more flexible within their subject areas because these will change more than most core classes.
In CTAE areas such as Sports Medicine or Video Broadcasting or Business, industry standards will change often. Sometimes these changes are even year to year. Teachers of industry must be up to date with what is going on in the working worlds which mirror their classes. If not, they may teach outdated material or procedures.
Core classes will rarely have the amount of industry reflective changes we in CTAE do. For example, 2+2=4 isn’t going to change. Neither is water freezing at 32 degrees. But, the way you wrap a sprained ankle or how best to interview for a job is more opinion based and will most certainly change over time. Because of these changes, CTAE teachers must be “elastic and fluid” across all aspects of their teaching.
