Nobody can deny that teaching is hard. Some people believe (including myself) that it is one of the essential skills to learn in this century. Whether you are a junior software developer or a renowned member of a firm, your capacity to communicate your knowledge effectively will determine your future success.
In this 15 min video, I teach how the Quicksort algorithm works the old way: with a blackboard and chalk. As you can see, I committed many mistakes. Considering that I spent two hours preparing for this, my performance was not as good as expected.
What else could have been worse?
For my new session, these are some preparation tips that helped me:
- Prepare a script of your presentation; having something written helps to clarify ideas and to sharpen the vocabulary for the session
- Record me during the rehearsal: it is incredible the many mistakes that we overlook if we don’t see ourselves during the performance
- Move my hands and speak slowly: the corporal language is essential, this is something that I’m still learning from the best speakers
- Practice, practice, and practice
