Electronics are an excellent way to help her to engage, but also a reward system can work. I had a student who was autistic and didn't like to touch anyone or anything and I would offer him a prize to shake hands with the principal during awards or to help another student with a project. This really seemed to help. I allowed him to choose his rewards so he had something to look forward to when there was an instance that made him feel uncomfortable.

I think you just need to get to know the student better. Find out why she doesn't like to work in groups, find out who her friends are, find out what she wants to work. Communication is key here and hopefully throughout your time communicating together you will build a relationship with her and she trusts you. When she learns to trust you it will be easier for you to ask her to do things that she may not want to do.

Consider electronics. Sometimes students will respond better to using aids like that better than a face to face helping session. If the student is competent enough to use the computer, see if you can obtain some lower level learning programs and let them try. If this works, try having the student work on the same program with a partner who doesn't mind. You might be able to ease them into participation.

Electronics and a reward system are both great ideas. However, there could be a much more simple resolution. I currently teach an autistic student that refuses to work in groups. One day, without reason in conversation, I asked him who his friend was in class. He told me who his friend was. The next time I assigned group work, I grouped him with his friend. They both worked eagerly and were very successful on the assignment. Since then, they have worked together on each partner assignment and I have never had any other problems.

Something you could try is to assign individual roles within the groups. For someone like this student who has issues collaborating, you could try to assign her to a more active role, such as note-taker, that would require her to listen to her group members' input, pay attention, and take note of what they are saying. You could also allow her to choose the group she would like to be a member of, as well.

I don't think forcing interaction is going to help this student at all. I think that allowing this student to work on her own and collaborating when she wants to would help, but in regards to her not getting the right answers you can work with her one on one to help her understand the topic and work on it. If she doesn't want to work with other students, don't make her because it isn't going to help anyone. Remain patient and if she doesn't want your help you can give her a physical copy of the lesson or how to do something and see if this will help her work.
