I hear you JDax as my DS will only ever do the "minimum". I don't find the fault in the rubric idea but in the writing of it in the manner you describe. I would rather the top grade say something along the lines of "Thoroughly describes the project and gives many examples that support the findings" or something along those lines. Something that allows both the teacher AND the student some room to make an evaluation based on the student's individual abilities yet is still objective enough for grading purposes.
