Hi Mark,
there is nothing like that built-in.
However, here is how I would do this:
I am assuming that each of the classes has a SCHEDULED date, maybe
you created the list of entries with `org-clone-subtree-with-timeshift'.
I am also assuming that these are children from some parent like
* Course
** Lecture 1
SCHEDULED <..>
** Lecture 2
SCHEDULED <..>
etc.
I would:
1. put the cursor on the "Course" headline.
2. Press `C-c C-x <' to restrict agenda commands to that tree
3. Press `C-c a L' to get the time line view
4. Move the cursor to the first entry that should be shifted,
maybe "Lecture 5"
5. Press `C-x (' to start a keyboard macro.
6. Press `7 S-right' to shift the date.
7. Move the cursor down to the next lecture (still
all the time in the agenda)
8. Press `C-x )' to end the keyboard macro
9. Press `C-x e' to execute the keyboard macro
for the next entry, etc etc
10. Press `C-c C-x >' to remove the agenda restriction
Org-mode is running in Emacs, don't forget that the full
power of Emacs is available in addition to what Org-mode
can do.

I teach a weekly class and have a number of tasks that
go into preparing for the class. I have an org file set
up with these tasks.
Occasionally I have to put off a class for a week. That
means all the following classes and their sub-tasks must
also be moved by a week. So far, I have had to expand the
entire tree and visit each task in turn and use the S-right
on each date to get the rescheduled time correct.
Is there a way to select a region and have org-mode add an
offset to each task (specifically the deadlines) in the
region?
Alternatively, is there a way of specifying my tasks such that
I can say that Task A is to take place 1w after Task B, or Task
C must take place 4d before Task D?
