The relevance of the selected research topic arises from the numerous challenges encountered in the education of prospective mathematics teachers. The purpose of this research is to substantiate the advisability of using the case technology in the formation of information competence for the future teachers of mathematics in the process of their preparation. This study employs a methodological approach that combines literature analysis, synthesis of pedagogical experiences, statistical observation and a pedagogical experiment to assess the impact of case technology on the development of information competence among students in the context of professional education for future mathematics teachers. The main results of this study include the creation of case groups and their integration into the curriculum for students specializing in 'mathematics' and 'mathematics-informatics', as well as a comparative analysis of the components of information competence among future graduates and their proficiency levels. The study's findings hold significant relevance for educators at the Higher School of Natural Sciences at Zhetysu University named after I. Zhansugurov, with the overarching objective of preparing competent, highly skilled and competitive mathematics teachers for the job market.
