No Opt Out can be used with any randomized response practice.
Index cards can be used to randomize responses by writing students’ names on them then shuffling and selecting a card for a response.
The numbered heads strategy can be used to randomize as students will be called according to a pre-assigned number the teacher has given them. Spinners, dice, or numbers drawn from a basket [hat or cup] can be used to ensure that the numbers are randomly chosen.
Students write their names on popsicle sticks that are kept in a cup. The teacher (or a student) pulls out a popsicle stick and calls the name on the stick to solicit a response to a question.
