Comparison of Highlighting Methods in Basic Calculations

Abstract (in Japanese) (See Japanese page) 
(in English) Basic calculations, such as the computation of positive or negative numbers and literal expressions, are the foundation for learning mathematics. These calculations are often subject to calculation errors due to the confusion caused by the difference in concepts when transitioning from arithmetic to mathematics. In our past work, we proposed and implemented a system to reduce calculation errors by highlighting specific parts of mathematical expressions during calculations. However, we could not clarify what kind of highlighting is appropriate. In this study, we conducted experiments using six types of highlighting methods to investigate what kind of highlighting is effective in basic calculations. Specifically, we investigated the appropriate highlighting methods and studied them through experiments to discover errors in already-calculated formulas. Experimental results showed that the method of coloring parentheses may be superior in the calculation of positive or negative numbers. It was also suggested that combining multiple highlighting methods in the calculation of literal expressions may reduce the visibility.
