Vocational education, The Developer Story
-
I had the opportunity to teach again at Suji High School.
-
Due to COVID-19 Pandemic, I conducted a 60-minute non-face-to-face video recording lecture.
-
The non-face-to-face meeting was awkward, but it turned out to be a beneficial experience.
-
You will see a little face in the upper right corner.
-
😅 (The material was delivered, but I don't know if the lecture was opened normally. )
-
Vocational lecture, all about development that software developers say
- Suji High School. For the first and second graders, we had time to learn about the job of a software developer.
- I pre-recorded (60 minutes) because of the COVID-19.
- It was a good time to introduce my students to the job of developer and to look back on my job.
- As I was in parallel with my work, I felt lack of preparation, and I felt a lot of regret for not having direct communication with students.
