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

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"teaching la matematica\") OR (\"teaching and matematica\"))) OR (\"teaching in mathematica\"))~".
• Removing quotes may allow a broader search: (((( teaching la matematica ) OR ( teaching and matematica ))) OR ( teaching in mathematica ))~.
• Adding a wildcard symbol may retrieve word variants: (((("teaching la matematica") OR ("teaching and matematica"))) OR ("teaching in mathematica"))*.
