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

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 de mathematica\") OR (\"teaching and mathematica\"))) OR (\"teaching of mathematica\"))~".
• Removing quotes may allow a broader search: (((( teaching de mathematica ) OR ( teaching and mathematica ))) OR ( teaching of mathematica ))~.
• Adding a wildcard symbol may retrieve word variants: (((("teaching de mathematica") OR ("teaching and mathematica"))) OR ("teaching of mathematica"))*.
