Perhaps you should try some spelling variations:
"teaching and mathematica" » "teaching in mathematics", "teaching en matematica", "teaching in mathematical"
"teaching con mathematica" » "teaching in mathematics", "teaching en matematica", "teaching in mathematica", "teaching for mathematica", "teaching to mathematica"
"teaching of mathematica" » "teaching of mathematics", "teaching in mathematical", "teaching la 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 of mathematica\") OR (((\"teaching con mathematica\") OR (\"teaching and mathematica\"))))~".
• Removing quotes may allow a broader search: (( teaching of mathematica ) OR ((( teaching con mathematica ) OR ( teaching and mathematica ))))~.
• Adding a wildcard symbol may retrieve word variants: (("teaching of mathematica") OR ((("teaching con mathematica") OR ("teaching and mathematica"))))*.
