That¡¯s a really interesting question! I can understand the dilemma. 
We give our students zero for the iRAT and zero for the tRAT if they don¡¯t show up at all. 
If they are late, we let them in and give them an iRAT paper to look at (but they can¡¯t submit answers). So those students get zero for the iRAT, but chance to think things over and thus help their team (with the tRAT, which they do participate in & get marks for). 
If a student misses the RAP session altogether for good cause (e.g. Medical evidence is provided), we give them the class mean iRAT (ignoring the zeros for non-attendance, but keeping in any zeros for students who got everything wrong – fortunately that doesn¡¯t happen often) and their own team tRAT score.
I can¡¯t say we did this because we¡¯d thought through the difference between students who show up and get zero on their iRAT vs students who don¡¯t show up at all. But it works, because even those who got a zero on the iRAT, are highly unlikely to get zero on the tRAT. They may be benefitting from their team-mates preparation, and coasting on their own minimal/non-existent preparation, but they are at least present, so hopefully the team dynamic and their team-mates disapproval will deal with that lack of preparation over time! The students who aren¡¯t present are getting zero on both iRAT & tRAT, and are also likely to be dealt with harshly if persistent ¡®no-show¡¯s in the peer evaluation at the end of the year. 
We would also like to think that our attendance monitoring processes would sort them out long before that, but that¡¯s a whole different story¡¦!

Subject: Re: tRAT Grading

For tRATs, I also use 4-2-1-0 with the 4-question IF-ATs, but the statement "I couldn't justify giving 1 mark¡¦" made me think of a philosophical dilemma that I have with iRAT grading. For iRATs, I just give 1 point for each question. Thus my iRATs are out of 10 points while my tRATs are out of 40 points (but they get scaled back to 10).

So here's my dilemma: What to do about students who get a 0 on the iRAT? (This is closely related to how to award partial credit on exam questions, which is another big area of philosophical difference in education.) These students clearly did not do adequate preparation, often no preparation at all. However, I sometimes feel the need to differentiate between those who show up for the iRAT and those who skip, because the former at least demonstrate some mental effort. For instance, it has happened once or twice where someone shows up so late that they miss the iRAT entirely and just take the tRAT.

Ultimately, getting a 0 on the iRAT is so rare that I don't dwell on it. But the philosophical question of what warrants a score of 0 is interesting (for me, at least) to think about. So I'm curious if others give out 0s on the iRAT or do you give some base score (say, a 1) to denote present but unprepared students. Also, note that I am working exclusively with undergraduates at a public state university, if that provides some context.

We use 4 - 2 - 1 - 0
We have A-D (4 option) MCQs for our tRATs, so I couldn©öt justify giving 1
mark to the students who have exhausted all the options.
If you have A-E then I can see 4, 3, 2, 1 (0) making more sense.
I wonder whether one gets more discussion with the 4/2/1/0 option. The
fact that getting it right first time is worth double the points may
encourage students to spend more time thinking/discussing their preferred
response and coming to a proper consensus. But that is just a gut feeling
- I wonder if anyone has tried to see whether it actually makes any
difference? Does anyone know of data on this?

Hi,

What is the most popular grading system for tRATs?  One point off for
each wrong answer (4,3,2,1)  or reduce by half for each wrong answer
(4,2,1,0)?  Other methods?  What are the pro and cons?
