Computer Sciences as school subject

Dear colleagues,,Today I am going to talk about computer sciences as one of the subjects which is teach for the secondary school students as a part of their assessment ,, To go deep in this topic we need to know many things. Nowadays many teenagers or even kids know about How to use computer at least they know the basics about it 

First what is computer sciences:
Computer science is the study of the theory, experimentation, and engineering that form the basis for the design and use of computers. It is the scientific and practical approach to computation and its applications and the systematic study of the feasibility, structure, expression, and mechanization of the methodical procedures (or algorithms) that underlie the acquisition, representation, processing, storage, communication of, and access to information. An alternate, more succinct definition of computer science is the study of automating algorithmic processes that scale. A computer scientist specializes in the theory of computation and the design of computational systems.^[1]
 Computer science in secondary schools is an area of increasing interest and concern to educators as well as to computer science professionals. But the most important question Why we teach computer sciences in our schools and is it really useful and implemented practically or it is just a theoretical subject? from my reflective experience when I was student Teaching computer is useful for students it can help them to prepare them 
self to future as we know nowadays we use computers in every sectors and it is 
required in many institutions to have a job but unfortunately it is not implemented in many schools for many reasons and I will talk about this challenges and how we can fix it .

The challenges that face implementing of I.C.T in our schools:

• The availability of the computer devices.
• Qualified teacher.
• The fund to repair and fix any problem in computers
• Ministry of education didn't make workshop or training courses for teachers to be updated to the new.

•  Curriculum developers should make computer education one of the core subjects to be offered in secondary schools.  

I wish if this subject is provided for preschool children and primary school students .
