◆6: A course to train your presentation skills and improve your ability to communicate both internally and externally
There are many readers who say, “I’m good at working diligently on a PC, but I’m not good at giving presentations in front of people.” However, even if you work as an engineer, you will have surprisingly many opportunities to give presentations. A useful course for such times is “Presentation course for engineers – Original presentation method that can be communicated many times more than now“is. Take this opportunity of the new year to learn presentation skills and eliminate any fears you may have.
Engineer presentations do not require advanced techniques like those of Steve Jobs, but it is OK as long as you can “convey the main points to the other person.” This course is designed to enable even “silent engineers” to give good presentations, based on the instructor’s experience as a person who had extreme anxiety and was not good at speaking in public.
