We investigated how the opportunity to learn (OTL) with different types of mathematics tasks are related mathematical literacy and role perceived control in relationship between OTL literacy. The structural equation modeling was applied data 1,649 Korean students from PISA 2012 database. four – algebraic word problems, procedural tasks, pure reasoning, reasoning were measured via student survey...

This paper presents a tool for labeling online handwritten mathematical expressions with ground truth automatically. We apply symbol hypotheses for segmentation and spatial relationship for matching between a template expression and a sequence of input strokes. By using this tool, we experimentally made a ground-truthed database contains 1,407 mathematical expressions and over 12000 symbols. St...
