In this case, I suspect it is because you aren't citing a specific other student, which would be "the other", so it takes the indefinite article "an" and mashes it up with "other". Why that happens with "other" and not other cases where we use "an" as the indefinite article is beyond me. Perhaps an etymological dictionary?
