Perhaps you should try some spelling variations:
"using computational models teaching programming" » "using computational model teaching programming" (Expand search), "using computational modeling teaching programming" (Expand search), "using computational modelling teaching programming" (Expand search), "using computational models teaching program" (Expand search), "and computational models teaching programming" (Expand search)
"using compilation in coding program" » "using combination in coding program" (Expand search), "using population in coding program" (Expand search), "using correlation in coding program" (Expand search), "using compilation an coding program" (Expand search), "using compilation on coding program" (Expand search), "using complication in coding program" (Expand search), "using compilation in cloning program" (Expand search), "using compilation in loading program" (Expand search), "using compilation in cooling programs" (Expand search), "using compilation in decoding program" (Expand search), "using compilation non coding program" (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: (("using computational models teaching programming") OR ("using compilation in coding program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"using computational models teaching programming\") OR (\"using compilation in coding program\"))".
• Removing quotes may allow a broader search: (( using computational models teaching programming ) OR ( using compilation in coding program )).
• Adding a wildcard symbol may retrieve word variants: (("using computational models teaching programming") OR ("using compilation in coding program"))*.
