Final answer:
The best S^D for getting a student with autism to come to an adult is option A 'Hi Johnny. Please come over here right now because it is time to start our lesson.' as it provides clear and explicit instructions, which are often helpful for individuals with ASD.
Step-by-step explanation:
The question 'Which is the best S^D to get a student with autism to come to an adult?' is centered around best communication practices with individuals diagnosed with Autism Spectrum Disorder (ASD). Based on professional approaches tailored to the needs of individuals with ASD, option A 'Hi Johnny. Please come over here right now because it is time to start our lesson.' is more detailed and provides explicit instructions, which can be especially helpful for a student with autism. This option gives clear guidance on what is expected and why action is required, which aligns with the structured communication preferred by many individuals with ASD.
Option B, 'Can you come over here?' is more open-ended and could be considered less directive. Although friendly, it lacks the specificity that might be necessary to prompt an action from an autistic student. Therefore, amongst the options provided, option A would generally be considered the best approach for calling a student with autism to come to an adult due to the clear and specific instructions given in the request.
