Аннотация. Статья посвящена анализу опыта организации инженерно-технологического обучения школьников. Описаны подходы различных регионов и образовательных организаций к созданию инженерных классов. Анализируются особенности организации образовательного процесса в инженерном классе. Особое внимание уделено теоретическим и практическим вопросам организации практикумов. Представлен опыт Московского государственного технического университета им. Н.Э. Баумана и Московского государственного областного университета, намечены перспективы сотрудничества. Ключевые слова: инженерно-технологическое обучение, инженерный класс, практикум.

The article considers the urgent problem of finding new highly effective methods for dispersing suspensions prepared using nanomaterials (boehmite, graphene, nanotubes). Based on comparative experimental data, it is shown that the ultra-jet treatment method has several advantages. For experiments, standard equipment for waterjet cutting of materials was used. A single crystal of diamond was used as a target for a high-speed nanosized suspension, the fastening of which was carried out in special technological equipment, which also performs the functions of collecting the treated liquid. The experimental results showed that the particle size after ultra-jet treatment exceeds the result of the traditional method of homogenization – ultrasonic treatment. An important result of the research was the establishment of the fact that the homogenization process begins at the stages of the passage of the nanosuspension through the focusing tube, and not only in the process of collision of the ultrajet liquid with the barrier.
