This article explores the application of constructivist pedagogical models in teaching chromatographic analysis, with a focus on skill development through problem-solving tasks. The research emphasizes how learners actively construct knowledge by engaging in hands-on chromatographic exercises that simulate real-world analytical problems. Various teaching strategies rooted in constructivist theory—such as inquiry-based learning, collaborative experiments, and reflective thinking—are examined for their effectiveness in enhancing students‘ analytical competencies. The paper also provides a methodological framework for integrating chromatographic problem-solving into the chemistry curriculum, contributing to the development of higher-order thinking skills and scientific literacy. Findings suggest that constructivist approaches significantly improve students‘ conceptual understanding, engagement, and practical skills in chromatographic analysis.

В статье рассматривается применение конструктивистских педагогических моделей в обучении хроматографическому анализу с акцентом на формирование навыков через решение задач. Исследование подчеркивает, как обучающиеся активно конструируют знания, выполняя практические хроматографические задания, моделирующие реальные аналитические проблемы. Различные стратегии обучения, основанные на конструктивистской теории, - обучение на основе исследования, совместные эксперименты и рефлексивное мышление, - рассматриваются с точки зрения их эффективности в развитии аналитических компетенций студентов. В статье также представлена методологическая основа интеграции решения хроматографических задач в учебную программу по химии, что способствует развитию навыков мышления высокого порядка и научной грамотности. Полученные результаты показывают, что конструктивистские подходы существенно улучшают концептуальное понимание, вовлеченность и практические навыки студентов в области хроматографического анализа.

Ushbu maqolada masalalarni yechish orqali ko‘nikmalarni shakllantirishga urg‘u bergan holda xromatografik tahlilni o‘qitishda konstruktivistik pedagogik modellarni qo‘llash o‘rganiladi. Tadqiqotda o‘quvchilarning real analitik muammolarni aks ettiruvchi amaliy xromatografik mashqlarni bajarish orqali bilimni faol ravishda qanday qurishi ta‘kidlanadi. Konstruktivistik nazariyaga asoslangan turli o‘qitish strategiyalari - tadqiqotga asoslangan ta‘lim, hamkorlikdagi tajribalar va refleksiv fikrlash - talabalarning analitik kompetensiyalarini oshirishdagi samaradorligi nuqtai nazaridan tahlil qilinadi. Maqolada, shuningdek, xromatografik masalalarni yechishni kimyo o‘quv dasturiga integratsiya qilishning uslubiy asosi keltirilgan bo‘lib, bu yuqori darajadagi fikrlash ko‘nikmalari va ilmiy savodxonlikni rivojlantirishga xizmat qiladi. Natijalar konstruktivistik yondashuvlar talabalarning xromatografik tahlil bo‘yicha konseptual tushunchasi, faolligi va amaliy ko‘nikmalarini sezilarli darajada yaxshilashini ko‘rsatadi.
