Perhaps you should try some spelling variations:
"based instruction python python programming" » "based instruction method python programming" (Expand search), "based instruction on python programming" (Expand search), "based instruction to python programming" (Expand search), "assisted instruction python python programming" (Expand search), "based instruction pythons python programming" (Expand search), "based instruction piton python programming" (Expand search), "based instruction pitons python programming" (Expand search)
"coder collision on coding program" » "dose collision on coding program" (Expand search), "or collision on coding program" (Expand search), "odd collision on coding program" (Expand search), "coder collision on cloning program" (Expand search), "coder collision on loading program" (Expand search), "coder collision on cooling programs" (Expand search), "coder collisions on coding program" (Expand search), "coder collision of coding program" (Expand search), "coder collision in coding program" (Expand search), "coder collision non coding program" (Expand search), "coder collision and coding 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: "((\"coder collision on coding program\") OR (\"based instruction python python programming\"))~".
• Removing quotes may allow a broader search: (( coder collision on coding program ) OR ( based instruction python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder collision on coding program") OR ("based instruction python python programming"))*.
