- Аннотация: The mission of Kolmogorov AESC is to teach gifted pre-University students (14-16 years old) at University style in order to simplify their start to science. One of important courses for students of chemical and biological classes is practical works on chemistry. Main goal of this course is verification and confirmation of knowledge obtained on lectures and from textbooks by own practice. Traditional sequence includes following steps. - Preparing tables for observations record at home, using lection materials based on a manual. - Experimental work in a laboratory, recording observations. - Preparing to answer questions from student’s book and to make conclusions on a base of experimental results - A colloquium with a teacher (control). One of main problems for this course is the lack of proper focus of students on key moments of experiments or substances properties. Therefore, we plan to improve the efficiency of practical works with the help of a new method of pre-colloquium control. During practical works, teacher or his assistant makes photos of substances or key moments of work and records short videos of processes if required. On the next lesson, these photos and videos are demonstrated to students. They must identify demonstrated substances, reactions and processes. This procedure stimulates students to be more observant and to pay attention to details of experiments. As a result students are more oriented in their works and demonstrate better knowledge and understanding of their results on the colloquium.
