| Outline of Final Research Achievements |
This study aimed to address shortcomings for improving the mathematical input efficiency for mathematical e-assessment systems. We have proposed a predictive algorithm in terms of a perceptron machine learning and developed an intelligent mathematical input user interface (UI), named MathTOUCH, by implementing such the algorithm. We examined the prediction accuracy using a dataset of general 4,000 mathematical formulae from five volumes of a mathematics textbook. The results showed that the accuracy of top ten ranking with our proposed algorithms achieved 85.2%. Finally, we conducted two experiments, i.e. a performance survey and an eight-week learning experiment, to evaluate the efficacy of MathTOUCH implementing STACK e-assessment system. As a result, we have shown that MathTOUCH enabled participants to enter mathematical expressions approximately 1.2 to 1.6 times faster than the standard interfaces and had a high level of user satisfaction in regards to mathematics input usability.
