Dr Muthen, Recently, I worked with a education assistant professor on her English reading growth grants. She asked me to do a regular 1st order CFA Model using three items. The first two items are learning effect, and learning trends. Each of them is comprised of 3 questions(Yes-1;No-0) having many missing values. The last item is the gain score between post-test and pre-test and it is the continuous variable. Honestly, I really got confused about her instructions. She want me to compute the average score of column 1 to column 3 as learning effect, and do the same thing as learning trends. Then, using MPLUS syntax to build the CFA model. MY intution is her opinion is incorrect but I didn't know how to give her an reasonable explaination. Thanks for your advise.
