Based on reviewing the original data that gave rise to the codes as well as the new scenarios contributed by our research group, we have generated the following descriptors or aspects of CUE:
“Strong” examples of CUE:
High cognitive demand
Mathematically correct
Realistic context and/or numbers
Address (or at least don’t add to) misconceptions
Numbers are selected intentionally
Match the purpose of the lesson
“Weak” examples of CUE:
Low cognitive demand
Wrong mathematically
Not realistic context and/or number
Encourage misconceptions
Selected randomly (number selection)
Don’t serve purpose of the lesson
