Perhaps you should try some spelling variations:
"teaching of mathematica" » "teaching of mathematics", "teaching con mathematica", "teaching de mathematica"
"teaching and matematica" » "teaching en matematica", "teaching en matematicas", "teaching la matematica"
"teaching de matematica" » "teaching de matematicas", "teaching la matematica", "teaching en matematicas", "teaching the matematica", "teaching in matematica", "teaching to matematica"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("teaching and matematica") OR ("teaching de matematica"))) OR ("teaching of mathematica"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"teaching and matematica\") OR (\"teaching de matematica\"))) OR (\"teaching of mathematica\"))".
• Removing quotes may allow a broader search: (((( teaching and matematica ) OR ( teaching de matematica ))) OR ( teaching of mathematica )).
• Adding a wildcard symbol may retrieve word variants: (((("teaching and matematica") OR ("teaching de matematica"))) OR ("teaching of mathematica"))*.
