Entrance slip reading for our October 10 class: what are the effects of marking, grading and ranking?

 An article on the effects of marking and grading practices in a secondary physics classroom:

•  Inquiry into assessment and evaluation of learning in a physics classroom

• (A supplementary article in case you are interested:  Jo Boaler article on marks in math class (from Time Magazine))

And some questions to prompt your reflections:

1) What are your "student bird" and "teacher bird" thoughts about assigning percentages or letter grades in the assessment of student work? What do the grades indicate? How are they arrived at? Whose purposes do they serve? What are positive and negative aspects to giving grades? to be assigned grades by an instructor?
