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

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