Purpose – The purpose of this paper is to investigate an efficient means of estimating the ability of students solving problems in the computer- based learning environment.
Design/methodology/approach – Item response theory (IRT) and TrueSkill were …
This paper presents a computational method that can efficiently estimate the ability of students from the log files of a Web-based learning environment capturing their problem solving processes. The computational method developed in this study …
We investigate short-term learning from hints and feedback in a Web-based physics tutoring system. Both the skill of students and the difficulty and discrimination of items were determined by applying item response theory (IRT) to the first answers …
