As Alex said, this can be fixed as a system administrator. All of the files are distributed with webwork2. You just need to link to the distributed directory.
Run
sudo ln -s /opt/webwork/webwork2/assets/pg/Student_Orientation /opt/webwork/courses/courseId/templates/
to create the link.
You could also run "rsync -av /opt/webwork/courses/modelCourse/templates/ /opt/webwork/courses/courseId/templates/" and that would ensure that all files are updated (that is assuming your modelCourse is up to date). However, if you have customizations of some other files (like the course_info.txt file) in a courses templates directory, it will overwrite those.
