Perhaps you should try some spelling variations:
"and computation using tangible programming" » "and computation using language programming" (Expand search), "and computation using time programming" (Expand search), "and computations using tangible programming" (Expand search), "and computation in tangible programming" (Expand search), "and composition using tangible programming" (Expand search), "and computational using tangible programming" (Expand search), "of computation using tangible programming" (Expand search), "and computation using extensible programming" (Expand search)
"using mobile python python programming" » "using mobile phone python programming" (Expand search), "using mobile pythons python programming" (Expand search), "using mobile piton python programming" (Expand search), "using mobile pitons python programming" (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: "((\"and computation using tangible programming\") OR (\"using mobile python python programming\"))~".
• Removing quotes may allow a broader search: (( and computation using tangible programming ) OR ( using mobile python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("and computation using tangible programming") OR ("using mobile python python programming"))*.
