Perhaps you should try some spelling variations:
planning research » learning research, teaching research
research studies » research series
resources cursed » resource curse, resources used, resources case
wbi teaching » ii teaching, iii teaching, cdio teaching
i teaching » ii teaching, 1 teaching, 3 teaching

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( _ planning research studies. ) OR ( ((wbi teaching) OR (i teaching)) resources cursed. ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( _ planning research studies. ) or ( ((wbi teaching) OR (i teaching)) resources cursed. ))~".
• Adding a wildcard symbol may retrieve word variants: (( _ planning research studies. ) or ( ((wbi teaching) OR (i teaching)) resources cursed. ))*.
