significa maestro
A sentence would be "Tengo un profesor terriblemente significa para mi clase de Historia de este año!" which is "I have a terribly mean teacher for my History class this year!"
With respect, the above misunderstands the meaning of 'mean' in the question. It does not mean (no significa) 'mean' in the sense of 'signify'; but 'mean-spirited', for example; perhaps the teacher has given an (in the pupil's opinion) low mark, or been critical.
In this case 'mean teacher' would be, perhaps, 'profesor bajor/ruin'
