Intelligent Mathematical Tutor Based on ChatGPT or DeepSeek

Many secondary school students in the Netherlands require additional support to prepare for their mathematics exams. This paper presents the design of a Massive Open Online Course (MOOC) featuring training materials tailored for the mathematics exams, integrated with a digital intelligent tutor. The tutor, which students can activate as needed, is embedded within the course content. Two versions of the tutor were developed: one powered by ChatGPT and the other by DeepSeek. To evaluate their effectiveness, both versions were tested on a set of problems from W4Kangoeroe, an annual mathematics competition for primary and secondary school students. The results indicate that while both chatbots are capable of generating correct mathematical solutions, their approaches often differ significantly from those provided by experienced mathematics teachers. This highlights the potential of AI-driven tutors to assist students but also underscores the need for further refinement to align more closely with educational standards and teaching methodologies.
