The positive changes that have taken place in the Republic of Kazakhstan over the past decade have had a significant impact on the system of teacher and student training. Educational programs are actively changing. The modernization of educational activities in schools is aimed at improving the quality of training highly qualified specialists, which includes the introduction of information technology into the educational process and research work.
In the context of the rapid development of science, technology and information flow, it is important not only to provide students with knowledge, but also to develop their ability to think critically, analyze and apply the information they receive in practice.
The State educational standard emphasizes the need to train graduates who are able to navigate the information space, apply technology, and learn throughout their lives.
Research plays an important role in the formation of critical thinking and the development of creative skills among students. Our research focuses on the use of problem-based learning (PBL) in computer science lessons as an effective method of developing students' research skills.

The aim of the study is to analyze the impact of PBL on the development of students' research skills and identify optimal approaches to organizing computer science lessons. The focus is on critical thinking, problem solving, information literacy, data analysis, and effective communication. To achieve these goals, a methodology has been developed that includes: 1. Analysis of psychological, pedagogical and scientific literature. 2. Using quantitative and qualitative approaches. 3. The application of a pedagogical experiment with preliminary and subsequent assessments of changes in students' skills. 4. Data collection methods: questionnaires, observation, analysis of educational materials and conducting lessons using PBL. Special attention was paid to the integration of real-world tasks, interdisciplinary projects, situational assignments and project work to stimulate students' research activity. For a deeper analysis, the study includes a discussion of the role of PBL in other areas of education, such as STEM, project activities, and digital technology integration. This makes it possible to establish a link between the approaches used in different disciplines and to emphasize the universality of PBL as a teaching method. For example, the results of using PBL in computer science were compared with the experience of implementing similar methods in the study of physics, biology and mathematics, where the emphasis is on developing research skills, critical thinking and innovation. The study also examined international practices of PBL application in the digital age.

The results of the experiment demonstrated that the use of PBL contributes to: • Development of independent problem-setting and problem-solving skills. • The use of information from various sources. • Effective communication and collaboration in the group. • Increase students' motivation and confidence in their abilities. In addition, interdisciplinary projects and participation in competitions helped students develop practical skills and receive awards. The use of PBL in computer science lessons opens up opportunities for creating an innovative educational environment that promotes the formation of research skills among students. My research contributes to discussions about the implementation of modern pedagogical approaches in educational programs and can be useful for teachers, students and researchers in the field of education. Thus, PBL not only develops students' research skills, but also increases their willingness to adapt to the challenges of the modern information society.
