The rapid development of digital educational technologies has created new demands for the automation and intelligent analysis of educational content. Across the world, and especially in countries undergoing rapid digitalization such as Uzbekistan, educational institutions are increasingly deploying e-learning platforms, digital textbook repositories, and automated assessment systems. These platforms generate and manage enormous volumes of exercises, questions, and instructional tasks that must be organized, classified, and evaluated in a principled manner. Without a rigorous approach to understanding the semantic content of exercises, such platforms cannot effectively adapt to the needs of individual learners, align with curriculum standards, or provide meaningful feedback to educators and policymakers. This article proposes a mathematical model for the semantic analysis of exercises used in automated learning systems. The model is built on three complementary components: vector-space representation of textual content, probabilistic dependency graphs that capture the grammatical and relational structure of exercise statements, and ontological mapping of domain-specific concepts drawn from official curriculum taxonomies. Together, these components allow the model to classify exercises by cognitive complexity, assess their semantic relevance to defined learning objectives, and evaluate their internal structural coherence. Experimental results obtained from a corpus of over four thousand Uzbek-language educational exercises demonstrate the effectiveness of the approach, yielding an average classification accuracy of 91.4% across STEM subject domains. The study makes a foundational contribution to the theoretical basis of intelligent tutoring systems and adaptive learning platforms in Uzbekistan.

Har bir xalqning ma’naviy va ilmiy taraqqiyoti uning fidoyi farzandlari, ilm ahli va ustozlari bilan belgilanadi. Jamiyat taraqqiyotida ilm-fan vakillarining, ayniqsa, yosh avlodni tarbiyalashga umrini bag‘ishlagan ustozlarning o‘rni beqiyosdir. Zero, haqiqiy ustoz nafaqat bilim beradi, balki inson qalbiga ezgulik, adolat, vatanparvarlik va fidoyilik tuyg‘ularini ham singdiradi.

Ushbu maqolada korxonaning biologik aktivlaridan hosil yig‘ib olingan paytdagi qishloq xo‘jaligi mahsuloti tushunchasi, qishloq xo‘jaligi aktivlarini baholashda qo‘llaniladigan joriy bozor qiymati metodologiyalari hamda biologik aktivlarni tan olish, o‘lchash va baholash tartiblari yoritiladi. Maqola avvalo qishloq xo‘jaligi tarmog‘ida baholovchi foydalanishi mumkin bo‘lgan turli yondashuvlarni aniqlaydi va bu metodlarni izohlaydi. Korxona haqqoniy qiymati ishonchli aniqlanishi mumkin bo‘lgan biologik aktivlar uchun haqqoniy qiymat modelidan, boshqa biologik aktivlar uchun esa tannarx modelidan foydalanadi. Tadqiqotga ko‘ra, hosil beruvchi o‘simliklar uchun tarixiy tannarx yondashuvi, tirik hayvonlar uchun esa haqqoniy qiymat asosida o‘lchash maqsadga muvofiqdir.

This article highlights the issues of forming and developing students' creative abilities, which are among the most critical tasks of the modern education system. The study analyzes the psychological and pedagogical foundations of organizing interactive collective work during the lesson process and highlights the differences between traditional teaching methods. The role of the synergy effect, the exchange of ideas, and methods such as "Brainstorming," "Case Study," and "Project" in developing divergent thinking in a collaborative learning environment is revealed.
