Well, I guess it will be extremely difficult to persuade your teacher to use the sem package in R. AFAIK, AMOS and LISREL have become the golden standard for SEM in China, and SEM has become a golden model for analysis in social science and psychology. I have been a cynic to SEM for a long time, because I strongly believe this model has been completely abused, and perhaps the "easy-to-use" AMOS has been helping people abuse SEM. A common phenomenon I see is, people do not care about the model at all - all they care about is whether AMOS can successfully compute the coefficients; if AMOS failed, they will try to (randomly) set constraints to the model, i.e. add/remove this arrow, drag some variables into/out of the model, set this coefficient/variance to 1.
Anyway, I encourage you to ask your teacher why AMOS is "more suitable". I have a couple of very ridiculous stories about the SEM software, in which I can only feel the blind faith in software. Sigh... The good thing is, R is open source, so is the sem package. You can see everything in it, and you can extend it as you wish (in case your teacher think it is less suitable).
