The article describes the improvement of the quality and efficiency of the teaching of the subject “Descriptive geometry” in higher technical universities by means of step-by-step problem solving. The reasons for the phased problem solving are explained where the problem is solved in seven stages and each stage is described with using algorithms. The subject of descriptive geometry is of great importance for the preparation of highly qualified specialists in technical colleges. Descriptive geometry is one of the sections of geometry, in which spatial figures, which are a collection of points, lines, surfaces, are studied by their projection images on a plane (or some other surface). In our Republic the training in general technical disciplines primarily relies on philanthropy. As emphasized in such subjects as philosophy, pedagogy and psychology, the teaching process should focus on the personality of the student. Because a student is a future specialist, he is a personality. Therefore, in the process of education, teaching technologies are designed so that the student, based on his personal abilities, can organize the process of independent and active learning. For a first-year student of a technical college, it is very difficult to begin by visualizing the construction of a visual image of geometric objects according to a given flat drawing and a mental representation of the position of spatial geometric objects, as well as the study of how to construct a visual image of the subject; the ability to freely draw drawings of machine parts, mechanisms and complex drawings. Especially the solution of positional and metric problems is considered as the most difficult. To solve this urgent problem we propose a phased solution of complex problems. Each student's ability to perceive the subject is different, so the solution of problems in this way gives positive results. Each stage of the task is set with using algorithms, which makes such difficult task for successful students to solve the problem more easily. As a result, it can be said that the step-by-step solution of the problems, the new pedagogical technology, the case-study, confirms the relevance of this article
