Perhaps you should try some spelling variations:
learning resource » learning resources, learning research, teaching resource
resource series » resources series, resource theories, resource studies
resource survey » resources surveys, resource security, resource strategy
resource curse » resource base
wbi learning » 2 learning, 3 learning, 4 learning
wbi teaching » ii teaching, i teaching, iii 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: (( wbi learning resource series. ) OR ( wbi teaching ((resource survey) OR (resource curse)). ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( wbi learning resource series. ) or ( wbi teaching ((resource survey) OR (resource curse)). ))~".
• Adding a wildcard symbol may retrieve word variants: (( wbi learning resource series. ) or ( wbi teaching ((resource survey) OR (resource curse)). ))*.
