In my experience, I came to the conclusion that project-based learning allows to use various techniques and methods to increase students' cognitive interest in the subject taught, students can use their life experience in the learning process, develop their creativity. Students use their acquirements in practical activities and everyday life, including for critical evaluation. With the help of this kind of learning, students' interest in the subject increases and the quality of knowledge improves.As a teacher I become the interlocutor for my student, and my student become my partner who has the right to make his own decision. The content of such lessons includes practice-oriented situational tasks that begin with the problematic question WHY? the solution of which noticeably increases the interest of students and they are easily involved in the discussion. Use of project-based learning technology activates cognitive interest in the subject, shows the practical significance and important role of the subject in human and social life, improves the quality of knowledge, plays a great role in career guidance work with students.
