I'm a nervous wreck about it because i get so intimidated by professionals, especially teachers. 
Next week, as part of my university course (not a teaching course), I will be spending three days in a primary one and two class. My aim is to observe and write a report on one of the children. I have to write how they are affected by their environment, noises, lights, other people. I have to write how they are doing in regards to the various sections of the curriculum (only the parts i witness).
My lecturer has told my class not to single out/stalk any of the children. Just to observe one we feel we can write the most about. But we mustn't let the child be aware that we have chosen them. We have to give attention/chat to multiple children.
We've also been told not to sit there with a notebook and make notes on the child as this is off putting/will distract the children and teacher. We must make mental notes then write them down at break times.
I would be grateful for any advice please because I am incredibly nervous.
My lecturer has told me to be there for 8.30am. But when I gave the school a courtesy call yesterday, they said be there for 9.15. Which time should i be there for? Would i be considered 'in the way' if i got there at 8.30?
What should I wear? My lecturer said not to wear a suit, black trousers, nothing too smart. But to go with a smart/casual style. WTF is that? I'm going to have to go shopping, aren't i?
What do teachers really think of students coming in and 'observing'? Do they think we're annoying and a distraction? Or do they think we're useful and will give us some tasks to do?
What do you think I should do at breaktimes? Go to the staff room? What the heck do I talk to teachers about? Should i take a packed lunch or go a wonder to a local shop? (I don't know the area).
i do suffer a bit from anxiety, and i know these are all really silly questions. But I'm so worried I'm going to make a fool of myself, or the teacher will report back to my lecturer that i didn't make full use of my visit.
