That was an interesting read! Always shocking to hear when people have never heard of the term TCK when they’re surrounded by them…
I am a TCK and a teacher, so it’s definitely good to think about these things. I agree with your suggestions, teachers need to be aware of TCK challenges and unique characteristics they might be able to use in the classroom. And they should also teach the other classmates about it because a teacher can only do so much. Most of all, TCKs need other people their age to show them the host culture and see how they can fit in.
TCKs need people who ask the right question, but who are also willing to listen. As long as it might take.
Remember that a child with Asperger’s is not as able to vocalise their needs as a typical child, so the teacher must help them to identify the underlying problem. This could be a disturbing noise or smell (including one we cannot sense), a word or phrase which has negative associations, frustration that something does not work properly, a certain type of clothing which irritates, a colour which disturbs and so forth. Behavioural problems can come in many forms, including temper tantrums, walking or running about the room, jumping, shouting, self-injurious activities, covering the face, eyes, mouth or ears, hugging (themselves), throwing things to the floor or across the room, talking to themselves, putting on or taking off items of clothing, making repetitive movements and more. Patiently assessing the situation and seeking to eliminate the cause is the key, and keeping a record of instances of problematic behaviour is very helpful as it can enable you to identify triggers (time of day, type of activity, location and so on).
