- Additional (eighteenth field) BubblesPerRow in Bubblesheet Format file.
- specify bubbles available for each question row (default is 10).
- Support case where question (or subquestion for optionresponse,
matchresponse, or rankresponse) requires more bubbles than in one line.
- Students prompted to bubble once in multiple lines.
- Numbering recognizes multiple lines per question.
- Also supports: imageresponse, stringresponse, formularesponse where
students leave link(s) blank if weight assigned is greater than
bubbles per line -- multiple lines also supported in this case.
For example:
- 15-bubble MSU Art History exams now supported on standard 10-bubble
bubblesheets used at MSU.
