I have been most effective with a arcane caster relying on mostly 'crowd control' and my trusty flaming sphere spell. At lower levels, flaming sphere is very effective, especially when you get a few on the big bad you just knocked out with color spray or hideous laughter. I say this because at level 3, a caster can deal up to 9d6 damage with each flaming sphere given combat lasts that long.
I tend to agree against 'blast' magic-users as a Wizard, they are really more of a 'utility' caster in most respects. Somewhere I saw a comprehensive guide on building wizards in PF, you might recommend your player to look at it if you can find it. There should be a link somewhere on the Wizards page of d20pfsrd.
If you want a really effective caster, use summoning spells.
I played a summoner once, not the class but a conjuring wizard who multi-classed cleric. Most fun I've ever had with a caster. Giant bees were lifting the halfling monk up to flying creatures so he could use flurry of blows against them. If you want to be even more creative, use levitate and summoned creatures to use falling damage to your advantage. ;)
More fun than a barrel of monkeys, just as fun as a falling barrel of monkeys.
