<div dir="ltr">My coauthor Julie has written about running her 10 year old son through our Haskell book, though the book was written for adults.

Haskell is also Julie's first programming language. I've cc'd her so she can say more about this if she wants.</div><div><br></div><div>Haskell is great for teaching kids logic, math, data structures - you just can't skip details the way you can with experienced programmers.

</span>It's more about algorithms than computer architecture. An imperative<br>
program very clearly describes algorithms; Haskell does not. Unless you<br>
have a very good understanding of things like lazyness, non-strictness<br>
and tail recursion, you wont know what happens when and how.<br></blockquote></span><div><br>«It is easier to optimize correct code than to correct optimized code.»<br>--Bill Harlan<br><br></div><div>More heretically I draw your attention to Bob Harper's SECP<br><br>«everyone knows that <span>algorithm</span>s as welearned them at school are irrelevant to practice. »<br><a href="http://www.cs.cmu.edu/~rwh/papers/secp/secp.pdf" target="_blank">http://www.cs.cmu.edu/~rwh/papers/secp/secp.pdf</a><br><br></div><div>In my view «CS is the science of algorithms» is one of those memes that has held back our field because it underplays data.<br></div><div>And traditional programming pedagogy (aka imperative programming) is wrong because it emphasizes code at the cost of data<br></div><span class=""><div><br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

<br>
</span>All the more reason not to teach Haskell. To CS undergraduates you might<br>
teach your favorite programming paradigm. They can take it, and they<br>
will also learn others anyway. To teenagers who might never learn<br>
another language, it is not a good idea.<br>
