# Bir Öğretmen Hayatımı Nasıl Değiştirdi? | Şafak Serkan Yılmaz | TEDxIzmir Source: https://www.youtube.com/watch?v=6PUh7L8vm74 Recap page: https://rapidrecap.app/video/6PUh7L8vm74 Generated: 2025-11-24T16:41:52.406+00:00 --- ## Quick Overview The speaker credits a specific geometry teacher, Yeşil Öğretmen, for profoundly changing his life by encouraging him to think critically and not just memorize, which led him to pursue a career in cartooning and eventually establish his own successful engineering firm focused on maintenance and repair. **Key Points:** - The speaker's geometry teacher, Yeşil Öğretmen, asked him a question about a geometry problem which he could not answer by rote memorization, leading to an interaction that encouraged open-ended thinking (01:33). - The teacher subsequently sent the speaker to the 'other classroom' (yan sınıf) where students were taught to think critically rather than just memorize, contrasting with the standard state school education (02:41, 03:22). - The speaker initially feared his teacher would be angry when he admitted not knowing the answer but was instead encouraged, leading to a realization that his thinking was different from the 'memorizing' students (01:57, 02:20). - The speaker later pursued cartooning and worked for a satirical magazine, but eventually founded his own engineering firm specializing in HVAC maintenance and repair (04:46, 08:41). - He contrasts the rote learning environment where students fear making mistakes with the open-ended thinking encouraged by his teacher, which benefits problem-solving in engineering and philosophy (09:04, 10:22). - The speaker notes that the teacher who taught him this open-ended thinking (which led him to cartooning) was the same teacher who, years later, was seen being praised by a successful former student (a tourist guide) who had excelled in math (03:37, 05:57, 16:32). ![Screenshot at 00:06: The speaker stands on the TEDxIzmir stage under a spotlight, with a large purple 'X' displayed on the screen behind him, illustrating the setting where he recounts his formative educational experience.](https://ss.rapidrecap.app/screens/6PUh7L8vm74/00-00-06.png) **Context:** The speaker, Şafak Serkan Yılmaz, recounts a formative childhood experience in 1992 in Ankara at a supplementary course (dershane) where he was publicly challenged by his geometry teacher, Yeşil Öğretmen, regarding a problem that required conceptual understanding rather than simple memorization. This interaction served as a pivotal moment, steering him away from rote learning and toward a more critical, analytical approach to problem-solving that influenced his career path. ## Detailed Analysis The speaker begins by greeting the audience and relating a common critique he received: that he talked too didactically, which he notes ironically, given the context of his story. He recalls a specific incident from 1992 in Ankara at a supplementary course where his geometry teacher, Yeşil Öğretmen, asked him a question about a geometric problem. The speaker admits he didn't know the answer because he relied on memorization rather than understanding, unlike the wealthy students who simply knew the answers. When he couldn't answer, he feared the teacher's anger, but instead, the teacher sent him to the 'other classroom' (yan sınıf) where critical thinking was fostered. The speaker realized that asking 'what do you think about this?' was more valuable than asking for a memorized answer. This experience, and the teacher's method, showed him the difference between rote learning and true understanding, which he later applied when he became a cartoonist for satirical magazines and eventually started his own successful HVAC maintenance and repair company. He contrasts this with the standard educational approach where students only learn to recall answers, leading to fear of failure. He concludes by thanking his teacher, Yeşil Öğretmen, whose approach fundamentally changed his life path, allowing him to succeed in fields like engineering and philosophy where critical thinking is essential. ### Early School Experience - People told him he spoke too didactically - He recalls being asked a geometry question in 1992 at a dershane that required thinking, not memorization - He was sent to the 'other classroom' where critical thinking was taught (00:08 - 00:38 - 02:41) ### The Teacher's Lesson - He feared the teacher (Yeşil Öğretmen) would be angry, but she encouraged him to think openly - This contrasted with the other students who were rich and only knew memorized answers (01:33 - 02:44 - 05:57) ### Career Path Shift - The experience shaped his approach, leading him to cartooning and later establishing an engineering firm focused on maintenance and repair (04:46 - 08:41) ### Contrast in Learning - He contrasts rote learning (which makes people afraid to fail) with open thinking, which is essential for engineering, philosophy, and life (09:04 - 10:22 - 13:33) ### Concluding Remarks - He thanks his teacher for teaching him to look at problems from different angles (e.g., the 18-year-old student who knew the formula but couldn't solve the problem) and for the positive impact on his life (13:57 - 14:44 - 15:45) ![Screenshot at 00:03: The TEDxIzmir logo displayed against a dark background, setting the scene for the talk.](https://ss.rapidrecap.app/screens/6PUh7L8vm74/00-00-03.png) ![Screenshot at 00:36: The speaker on stage, with a blurred classroom photo from 1992 projected above him, illustrating the memory he is about to share.](https://ss.rapidrecap.app/screens/6PUh7L8vm74/00-00-36.png) ![Screenshot at 02:29: The speaker uses hand gestures while talking, emphasizing a point about engineering principles.](https://ss.rapidrecap.app/screens/6PUh7L8vm74/00-02-29.png) ![Screenshot at 04:40: The speaker stands in full view on the circular red stage, with the large TEDxIzmir logo visible behind him.](https://ss.rapidrecap.app/screens/6PUh7L8vm74/00-04-40.png) ![Screenshot at 14:31: A differential equation \($u\_t + \(x^2 - 1\)u\_x = 0$\) is displayed on the screen, symbolizing the technical knowledge he references.](https://ss.rapidrecap.app/screens/6PUh7L8vm74/00-14-31.png)
