Perhaps you should try some spelling variations:
information source » information sources, information resource, information resources
teaching dimension » learning dimension, teaching design, teaching decision
source teaching » source tracking, course teaching, core teaching
array profiling » array processing, microarray profiling
array formulas » area formulas, harrop formulas, array formats

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

• Performing a fuzzy search may retrieve terms with similar spellings: information source teaching dimension ((((array formulas) OR (array profiling))) OR (array format))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "information source teaching dimension ((((array formulas) OR (array profiling))) OR (array format))".
• Adding a wildcard symbol may retrieve word variants: information source teaching dimension ((((array formulas) OR (array profiling))) OR (array format))*.
