Get entries from subpage

I try to get the entries from a child page by

{{ entries:listing folder="methods/Teaching*" }}
...
{{ /entries:listing }}

No entries will be shown at the page.

If I try the following I see all child pages of the page methods incl. the childs of "methods/Teaching/".

{{ entries:listing folder="methods*" }}
...
{{ /entries:listing }}

What am I doing wrong?
