Since abstraction is "hiding" the classic procedural, meaning you have 
to ultimately talk to MySQL, or any database, with what it understands, 
I'd teach them both.  First, the classic, then the abstract (PEAR). 
Given the amount of time, I would cover PEAR::DB over against ADODB for 
the simple fact that there is a lot more happenin' in PEAR and they 
should be exposed to what it offers--besides DB abstraction.  Of course, 
it wouldn't hurt to provide an example of ADODB where they don't have to 
actually code and run it.

As to learning the syntax of basic SQL statements, I'd spend some time 
entering basic SQL commands using the MySQL command line client  (demo 
the MySQL GUI too!) before coding it in PHP.

That said, I would also make sure they learn mysqli.  If that sounds 
like a lot, it is.  I'm sure anyone who has taught (and learned!) 
programming appreciates the time that can be saved by providing 
partially coded examples (for a worksession) where they only have to 
complete a small percentage of the code.  After all, it's not a data 
entry or typing class.  You can provide complete examples as a part of 
the course documentation.  They need to walk away with a good 
representation of what they are actually going to run into "out there".

It pretty much boils down to how much time they have for *doing*.  I'd 
rather cover 70% of "the material" and have them feel comfortable with 
90-95% of it rather than trying for "100%" of the material and have them 
feel comfortable with 65-70%.  It's about building confidence as well as 
skills.  At the end of a class, I want them to say: "Wow, I really 
learned a lot!" and *not*  "The instructor was really knowledgable".

my $0.02 for what it's worth,
John
