Why Most Teachers Never Get Better: A 2018 Study on Video Analysis vs. Practice in Germany
Florian Treisch's 2018 study from Germany reveals a shocking truth: simply practicing teaching doesn't make you better. In fact, it can even make you worse. This video breaks down a rigorous experiment with 71 physics student teachers. The baseline group—those who only practiced—showed zero improvement in their ability to perceive and react to classroom dynamics. But the group that used video analysis? They exploded in growth across all measures. Even more mind-blowing: the better a teacher's physics knowledge, the worse their teaching perception became. It's a cognitive overload trap. Discover why the 'Lehr-Lern-Labor' (Teaching-Learning Lab) seminar, combined with structured video reflection, is the only way to break the cycle of mediocrity. Learn the three levels of professional perception—describing, explaining, predicting—and how to unlock them.
