Understanding Retakes

I received an email from a student yesterday inquiring about re-assessments. I thought to post my response here. I want you all to understand how you're being graded. 

If I did well on some of the standards in a quiz, but not all, would I be tested again only on the standards I did not do well on?

Once you score a 3 on a particular standard, you are set with that standard for the mastery component of your grade (80%). When the standard comes back up on future standard assessments I will still score it, but you won’t be pulled down from a 3 to a 2. Only the standards that you haven’t yet mastered can impact your grade. So you should devote the majority of the SA time to these standards. 

 Also, what constitutes proof of practice? 

Proof of practice will be the assigned homework or in the case of our first unit on scientific tools, the summer work. The summer work includes standards 3, 4, 5, 6. If you would like to practice standard 1 I have a problem on my website you can try (click files, AP Physics, 1- Scientific Thinking). You will show me the practice you completed to prepare for the next standard assessment. After a conversation with me about this practice, I will give you another SA. 

A related question: When is a convenient time for me to retake the quiz that we took two classes ago?

I plan on giving you all an SA next class on STT.1, 2, and 3 and then another one on Thursday covering 4, 5, and 6. If you would like to complete another assessment outside of these times, you can do so during your lunch period. Just let me know in advance so I can have everything prepared.

You can comment below if you have any other questions about my flavor of SBG and I will respond.
