First, let's briefly explain the scoring in the tRAT.
tRAT questions can use a decreasing scoring scale, meaning that with each attempt, marks are deducted.
For instance, a question with say 5 answer options can have the following scoring scale: "4, 2, 1, 0".
This means that if a team select an option that is correct in the first attempt, then they will get 4 marks for this question and they can move on to the next question.
However, if they did not get the correct answer in their first attempt, on their second attempt, if they get the correct answer, then they will only be given 2 marks for the question.
If they did not get the correct answer in their second try, then the next attempt will grant them 1 mark if they choose the right one.
Any other attempts after their third try, regardless of whether they select the correct answer or not will credit 0 marks.
You can change the scale for the tRAT in the Scratchie authoring
The default marking scale is 4, 2, 1, 0.
Can I have negative scoring scales?
Some teachers I know have a tRAT marking scale as "5, 2, -2, -5". Yes, I'm not kidding! 😀
What question types can I use for tRAT?
For tRAT -just like for the iRAT, you can use Multiple Choice (single best answers), Very Short Answers and Mark hedging question types.
Can students see their (and their team's) iRAT individual answer selected while they discuss answers in the tRAT?
Yes. If you have turned on confidence levels in for the iRAT, then you allow the students to view in the tRAT all the answers they have picked for their questions and their confidence levels.
👩🏻🔬 This feature is based on a research project we did to speed up the students discussions in the tRAT questions. Read about this in the Research section.
To do this, take a look at the Authoring instructions and then see the Student's view in the other tab.
Make sure you turn on the option in the tRAT (Scratchie tool):
Enabling confidence level display in the tRAT
If you use the TBL Wizard to create your design, this option is selected by default.
When reaching the tRAT, students are able to see which answer every peer in their team selected in the iRAT along with the confidence level.
Scrolling over the profile pictures allow you to see the student's name -in case like me, you are terrible with names!
Can I display the students iRAT answers in the tRAT anonymously?
Yes. Some students might be a bit apprehensive about showing their name next to a wrong answer.
Just check the option to "Do not display students' names with confidence levels" option and now students can see that headcounts for each answer and the confidence levels for them, but no names are displayed.
Can I use mark hedging question type and still show confidence levels?
Yes, mark hedging and confidence level play along quite well. When both in use, student will be able to see the distribution of marks each student selected in the iRAT

Can students raise challenges/burning question while answering questions in the tRAT?
Yes. But it is optional though -however it is ON by default.
Enabling burning question in Scratchie authoring
The student leader is able to add challenges or burning questions on behalf of the team.
Can questions be shuffled for each group?
Yes, and each the question order for each team will be different
If you require questions to be shuffled in the tRAT, enable the option to do so as follows.
