Often, a student will create a program, but it will not be visible to the teacher from the Teacher Page when the teacher selects that student. When this happens I will ask the student to send me the link to the project. Using the link I can open and modify the project. It works just like it should for a teacher, except that the project does not appear on the list.
Note that the student did not need to change the privacy setting to “public”. It is still private like it should be.
