Your code works perfectly, see below,  so my only theory is that
@string doesn't have what you think it has.
Can you print it before the split?

irb(main):021:0> @string = "science+students"
=> "science+students"
irb(main):022:0> @cmds = @string.split('+')
=> ["science", "students"]
irb(main):023:0> for @item in @cmds
irb(main):024:1> puts 1
irb(main):025:1> end
1
1
=> ["science", "students"]

Jesus.
