In an Intelligent Tutoring System (ITS), the graphical user interface is the main mode of interaction between the program and the user. Thus, it is important to evaluate its usability, which is the system's efficiency and ease of use. For these evaluations, methods such as Nielsen heuristics and questionnaires are more recurrent. However, such procedures cannot detect problems that were not foreseen...
Intelligent Tutoring Systems (ITSs) for Math still use traditional methods of input, such as computer keyboard and mouse. This strategy exposes students to a high extraneous cognitive load, due to the way the students are used to work, what could impair their learning. This paper presents a tool for Math ITSs that uses the student handwriting as data input. This tool was integrated into PAT2Math,...
In order for an Intelligent Tutoring System (ITS) to correct students’ exercises, it must know how to solve the same type of problems that students do and the related knowledge components. It can, thereby, compare the desirable solution with the student’s answer. This task can be accomplished by an expert system. However, it has some drawbacks, such as an exponential complexity time, which impairs...
