MDIR Constructor: Interactive digital activities for developing reading and writing skills with natural numbers

The article presents MDIR Constructor, a digital authoring environment for creating interactive digital textbooks and learning activities across different school subjects, with a particular focus on mathematics. The system includes modules such as NumeralsMathLab and NumeralsVirtLab, which help students to develop reading, writing, and numerical literacy by converting numbers to words, self-assessment tasks, and mathematical dictations that provide instant feedback. The incorporation of Python libraries and AI tools into the Delphi programming environment enhances system adaptability, scalability, and multilingual support. By combining interactive digital resources with traditional curricular objectives, MDIR Constructor provides meaningful learning experiences, supports real-time feedback, and improves students’ fluency in numerical literacy. The paper also discusses the implications of integrating artificial intelligence and interactive digital tools into mathematics education, highlighting opportunities for adaptive and personalized learning.
