Perhaps you should try some spelling variations:
"teaching computational _ computer program" » "teaching educational _ computer program" (Expand search), "applying computational _ computer program" (Expand search)
"using computational code example of" » "and computational code example of" (Expand search), "using computational model example of" (Expand search), "using computational cost example of" (Expand search), "using computational models example of" (Expand search), "using computational code examples of" (Expand search), "using computational case example of" (Expand search), "using computational one example of" (Expand search), "using computational code sample of" (Expand search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("teaching computational _ computer program") OR ("using computational code example of"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"teaching computational _ computer program\") OR (\"using computational code example of\"))".
• Removing quotes may allow a broader search: (( teaching computational _ computer program ) OR ( using computational code example of )).
• Adding a wildcard symbol may retrieve word variants: (("teaching computational _ computer program") OR ("using computational code example of"))*.
