Perhaps you should try some spelling variations:
"using computational modeling teaching programming" » "using computational modeling teaching program" (Expand search), "and computational modeling teaching programming" (Expand search), "using computational models teaching programming" (Expand search), "using computational spelling teaching programming" (Expand search), "using computational during teaching programming" (Expand search)
"using imputation and coding program" » "using mutation and coding program" (Expand search), "testing imputation and coding program" (Expand search), "using indentation and coding program" (Expand search), "using computation and coding program" (Expand search), "using reputation and coding program" (Expand search), "using imputation and cloning program" (Expand search), "using imputation and loading program" (Expand search), "using imputation and cooling programs" (Expand search), "using imputation and coping program" (Expand search), "using imputation and cooling program" (Expand search), "using imputation and cooking program" (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: "((\"using computational modeling teaching programming\") OR (\"using imputation and coding program\"))~".
• Removing quotes may allow a broader search: (( using computational modeling teaching programming ) OR ( using imputation and coding program ))~.
• Adding a wildcard symbol may retrieve word variants: (("using computational modeling teaching programming") OR ("using imputation and coding program"))*.
