Hello everybody!
I am uploading a series of courses for a B4X (B4J) teaching program for middle and high school students.
The total project consists of 20 different modules with a total duration of approximately 60 hours.
The program is divided into courses where each is accompanied by:
- Brief Theory (in pdf and docx) in English and Greek Language (Spanish translation also available here )
- Power Point Presentations (pptx)
- Examples (solved)
- Exercises (also solved for the teacher).
Since the program is aimed at students with little or no programming knowledge, an attempt was made to hide enough details in order to make it more understandable. So forgive some omissions.
The material uploaded to my github
here.
You can download full
v2.0 pdf for printing
here.

If you liked my work a
cup off coffee is always welcome. Thank you.
New word files includes and Greek Translation. Some changes to curriculum also made.
There is also a Spanish translation. Many thanks to user profeberja. You can find it on his github here
