Ideally, use of the word "Look" means something to the effect of "I'm paying attention to this, you should pay attention to it, too." Those teaching LOOK can use it to try and capture the attention of their learner, and their learner likewise can use it to try and capture the attention of their teacher.
May pair well with COME. Introducing them at the same time provides opportunities to distinguish them from each other during modeling.
Meanings and uses
Get attention from any person.
Please give me your attention.
Get a teacher's attention and cause her to look at her
Among our group of successful modelers, the following techniques were used successfully:
Said "do you need attention?" when she would sit and stare, then pressed the button, then said attention. After that, learner received lots of pets and snuggles.
Learner already knew the word. Pressed the button and pointed in the direction I wanted him to look.
Had previously taught learner to look at us when we said look. We then gave the learner the button and let her figure it out for herself.
What seems to have worked well
Among our group of successful modelers, the following seemed to be helpful:
Using it when it was natural to do so and it seemed like she already wanted attention.
Using the word first as a command.
What seems to have gotten in the way
Among our group of successful modelers, they avoided doing the following:
Forcing it if the learner seemed hyper.
