Being Australia based, I can't really gauge if some of the teaching time was spent on computer science, how that would impact on the teaching of the other subjects. I don't think the subject would be appropriate for every student. While I see programming and the fundamentals of an operating system as a worth while venture for a good proportion, much of what I've seen offered around my locale as whatever the local schools name their computing course for their students, (I don't have my own kids so my bubble is mostly adults, so I'm basing this only on two kids in my area, more so the kid who's school laptop I was subsequently asked as a favour to sort out) don't seem to avoid the indoctrination of bad habits while reinforcing there's only one main OS. I dare say this might just come down to the individual teacher or staff assigned to oversee the course and possibly adjusting accordingly, to the needs of each of their students.
