My limited teaching experienced was based on these points:
- What I'm trying to teach is problem solving. Programming language
is a tool to accomplish this task.
- Fundamentals are what I call linguistic constructions
(loops, if-then-else, data structures and so on).
- Solutions are expressed in pseudo-code, which I describe as
a midpoint between natural and artificial language. So they can
solve problem even if they think they can't program.
- First, let students try to solve their problem with linguistic
constructions they learned so far. Perhaps the problem is subtly
stated to be hard to solve. Then, teach new constructions, that make
problem easier to solve. This way, in my opinion, things are better
understood and remembered.
In order to follow such points, programming language must be very
simple. Translating from pseudo-code to a programming language is
supposed to be seen as the simplest of the phases.
Perl is sintactically too complex. Pascal is a tradition,
and is close to what students will learn next years (but, of course,
has a lot of
limits). As I said, I'd like to use Python.
I think we actually agree :).

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
