Perhaps you should try some spelling variations:
"teaching computations in sampling program" » "teaching computational in sampling program" (Expand search), "teaching competitions in sampling program" (Expand search), "seeking computations in sampling program" (Expand search), "teaching computations in labeling program" (Expand search), "teaching computations in smoking program" (Expand search), "teaching computations in jumping program" (Expand search), "teaching computation in sampling program" (Expand search), "teaching computation of sampling program" (Expand search), "teaching computation and sampling program" (Expand search), "teaching computations and sampling program" (Expand search), "teaching computations air sampling program" (Expand search), "teaching computations _ sampling program" (Expand search)
"using modeling vpython python programming" » "using modeling method python programming" (Expand search), "using model vpython python programming" (Expand search), "using modern vpython python programming" (Expand search), "using models vpython python programming" (Expand search), "using modeling python python programming" (Expand search), "using modeling pythons python programming" (Expand search), "using modeling piton python programming" (Expand search)

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 computations in sampling program\") OR (\"using modeling vpython python programming\"))~".
• Removing quotes may allow a broader search: (( teaching computations in sampling program ) OR ( using modeling vpython python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("teaching computations in sampling program") OR ("using modeling vpython python programming"))*.
