IT needs to be given that same level of significance and importance that the disciplines of English and Mathematics get in the Senior School (Upper Secondary) as ‘Core’ subjects. In other words, every single student in Years 11 and 12 (last 2 years before University - Qld, Australia) may not study these subjects but they are strongly recommended to do so.
In today’s networked world where IT is unpins so much of todays relationship, business, educational and social, a sound grounding in IT should not be assumed to be absorbed by osmosis, but needs to be purposely integrated into the education of our students before they leave Secondary School.
Also, IT involves a new way of thinking about problem-solving:
It's called Computational Thinking,
Computational Thinking involves some unique knowledge and paradigms, as well as a wide skill set. Among the foundational areas of study are the following:
Most of these areas are to some degree unique to IT and can certainly be better taught through the use if IT, than in other academic subject disciplines.
For example, Algorithms are used not only by computer scientists and computer engineers, but also by many in other engineering and science disciplines. Also Shannon Information Theory is not only of use within the discipline of IT but also important in the study of genetic coding.
