The one with a penchant for chucking textbooks on desks from a distance. The one with coffee breath strong enough to peel paint off the wall. All the ones who killed your enthusiasm with teaching methods seemingly designed to bore the most energetic of children into a dull-eyed stupor.
Happily, our memories of the worst teachers fade over time, irrelevant as we get on with our day-to-day lives. But the ones who do pop into our heads occasionally – when we think about how our interest was sparked in a certain topic or why we got into the career we did or the subjects we adored – are the good ones. The best ones. The relevant ones.
Which might explain why a video – which you can watch below – of one Dutch biology teacher's unusual lesson has gone viral recently, at time of writing clocking up nearly 140,000 views.
Debby Heerkens, who teaches seventh grade (that's the first year of secondary school to us) at Groene Hart Rijnwoude School in the Netherlands, has come to the world's attention after she took to her desk and started taking her clothes off to teach the students about the human body.
Not quite as worrying as it sounds, as Heerkens was wearing layers of leggings and tops that mapped out the body's muscles, bones and internal organs in a uniquely memorable way.
Dutch news site Omroep West reports that the teacher was inspired to try something new when she saw someone wearing similar leggings and searched online for her outfit. The school's director knew of the plan and the school has since been happy to post pictures and video on its Facebook page.
Heerkens told CNN that her students were initially “a little bit in shock because they thought, ‘The teacher is taking off her clothes,’ until they saw what was underneath.”
Yep, it's just one part of one lesson in one school in a different country, but it's apparent we'll always be fond of those teachers who go the extra mile to inspire. All that remains to be seen is how she'll top it next term...
