Grading

There will be weekly problem sets, but no final exam.


Grading System for Problem Sets (Teaching Assistant Michael Forbes)

The grading system for the assignments this year will be based on an augmented letter system. Problems with well defined physical concepts and ideas will be assigned one of the following grades:

α Physical understanding seems to be correct.

β Something is wrong: some physics is not understood or incorrect, but basic idea is there.

γ Physics is wrong, or off base.

δ Problem not attempted.

These will be augmented with ± depending on whether or not the explanation was good (+) or confusing (—). These signs are very subjective: a negative sign might mean that I am a moron and did not understand your perfectly clear explanation. In any case, I hope you find these useful: They will not affect your overall grade in the course. For example: note that a β¯ might indicate that you have something wrong, but I could simply be confused by your explanation. In this case, please come see me if you think I simply misunderstood you.

Problems with direct answers may be marked out of numerical points for correct results and/ or mistakes. Ultimately though, these points will probably be less important than the letter grades for physical understanding.

For all results, please try to explain the physical meaning. I doubt that I will have time to go through every result to find all of the sign errors, factors of 2 etc. If you can explain why your answer is physically reasonable, or why there is obviously a mistake somewhere, it will make my job much easier (and hopefully you will learn more). Also, if you have any insights, revelations or ideas about a problem, please write them down or explain them to me: I will endeavour to share anything that seems important with you via recitation or comments on the solutions.

評分

本課程將有每週問題集,但沒有期末考試。


問題集的評分系統(助教Michael Forbes)

本學年作業的評分系統將基於擴充了的字母系統。很好地定義物理概念,能清晰地闡明想法的問題將獲得如下的成績之一:

α物理理解看起來是正確的。

β有些錯誤:對某些物理知識不理解或理解錯誤,但基本的想法是對的。

γ物理知識錯了,或偏離基本概念。

δ沒有思考問題。

附加的±取決於解答得好(+)或含糊不清(-)。這些符號非常具有主觀性:負號可能意味著我是個傻瓜,沒有理解你十分清楚的解釋。無論如何,我希望你們知道:它們將不會影響你們這門課的總成績。舉個例子:注意β¯也許意味著你有些地方出錯,但我可能被你的解釋搞糊塗了。在這種情況下,如果你認為我誤解了,請來找我。

對於有直接答案的問題,結果正確或有錯都將給出數位分數。 儘管如此,數位分數將沒有表示物理理解的字母等級重要。

對所有的結果請解釋物理含義。我懷疑我是否有時間去找出每個結果中的符號錯誤,因數2等等。如果你能解釋為什麼你的結果是物理上合理的,或者某處為什麼有一個明顯的錯誤,這將使我的工作變得容易很多(希望你也會學到更多)。還有,如果你對這個問題有更深入的見解、啟示或想法,也請你寫下來或解釋給我聽:我將在復習課或答案評語中竭力與你分享看起來重要的任何東西。
