Perhaps you should try some spelling variations:
"based instruction using coping program" » "assisted instruction using coping program" (Expand search), "based construction using coping program" (Expand search), "based obstruction using coping program" (Expand search), "based constructions using coping program" (Expand search), "based instruction using cloning program" (Expand search), "based instruction using computing program" (Expand search), "based instruction using cooling programs" (Expand search), "based instruction using coding program" (Expand search), "based instruction using coupling program" (Expand search), "based instruction nursing coping program" (Expand search)
"by computational on coding program" » "_ computational on coding program" (Expand search), "and computational on coding program" (Expand search), "by computational one coding program" (Expand search), "by computacional on coding program" (Expand search), "by computational and coding program" (Expand search), "by computational on cloning program" (Expand search), "by computational on loading program" (Expand search), "by computational on cooling programs" (Expand search), "by computational non coding program" (Expand search), "by computational of 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: "((\"by computational on coding program\") OR (\"based instruction using coping program\"))~".
• Removing quotes may allow a broader search: (( by computational on coding program ) OR ( based instruction using coping program ))~.
• Adding a wildcard symbol may retrieve word variants: (("by computational on coding program") OR ("based instruction using coping program"))*.
