Question: Why does Yoda seem so "childish" when Luke first meets him in the swamp? I mean in comparison to Episode III when he seemed much wiser. Is there any reason for this?

Answer: It's a trope popular with many of the Asian films (and some fantasy books) that inspired Lucas' original trilogy. The powerful master is often encountered first as a seemingly harmless (or meaningless) person only to unveil themselves later to the protagonist's surprise. In many respects, it's like Obi-wan's first appearance in A New Hope.
Chosen answer: Yoda was testing Luke. Luke was looking for a great Jedi warrior and expected to find this great man or creature, not a short, little, funny, "weak", creature. Yoda knew Luke must get past preconcieved ideas and conceptions of what it takes to be and become a Jedi. Luke failed this initial test.
