I won't bore you with statistics--how many schools don't have programming courses, the percentage of boys to girls in computer science classes... I just think that coding is an amazing activity for all students. It promotes thinking, reasoning, problem solving. It can be a hobby or a career! The shortage of progammers in he US is already significant. In the future, this shortage is expected to grow exponentially.
If you are interested in participating with your class or school, more info can be found at Hour of Code or Code.org. The work has been done for you and it is really easy to implement. Even if you don't have any computers or tablets, there are unplugged activities that students can do at http://csedweek.org/learn. All students should be introduced to programming.
