It is not a matter of when and where open lessons are held, but rather deep-rooted, deep-rooted scientific, theoretical and logical basis. It should be noted that there is a clear lesson about the same subject. Assistant of the Department of "Hydrology and Hydrogeology" of the Institute Mansurov Safar Rahmankulovich "Determination of parameters of transverse section of water flow. The open lesson on the topic "Processing of depth measurement data" on March 18, 2019 at B-403 auditorium "Hydraulic engineering", direction "5450400 - Hydroelectric power plant and pumping stations" was transferred to 2nd year 201 group students. Open lesson was attended by professors-teachers of the department "Hydrology and Hydrogeology" of ISMI, senior scientific associate Ibragimov I. Yu. At the beginning of the lesson, the teacher told the students: The teacher was the subject, the distribution materials were distributed to the students. Initially, he explained the depth measurement functions, the purpose of measuring the depth of water flow, the processing of results based on the measured data, the equipment for measuring the depth, and the classification of measuring instruments and the major morphometric elements of the riverbed transverse. At the end of the lesson, the teacher evaluated each student according to their active participation. Practical lesson was held in an interesting way in the form of questions and answers between students and teachers.
