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

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