Also if the player so wishes he can ignore str and keep it at 10 go with weapon finesse and just use his dex to hit and later get his weps enchanted with agile to also use his dex for damage.
And there is an archetype for the fighter class that would let him reduce the penalties for using two 1-handed weapons to the same as wielding a light weapon in the off hand. Of course, he needs to get to level 11 before that happens. Over all, might be better to get him to dual wield short swords until then since the penalties are a bit stiff otherwise (-4 to each attack roll instead of compared to -2 if he used a light in the off hand)
It also lets him use both weapons in a standard attack instead of a full attack at level 9.
jordain, there are no "use two weapons" rules in the Beginner Box. If you're adding in rules from the Core Rulebook or the PRD, it's as concerro said: look toward the end of the Combat chapter.
You may also want to take a look at the Beginner Box Transitions document, which talks about adding in rules from the Core Rulebook and where to find those rules.
