The main purpose of laboratory works is to study certain physical, chemical processes, their regularities, and to obtain reliable results. This can be achieved only under special conditions in a specially designated room, in other words, in the laboratory. You can carry out these experiments in accordance with the possibilities, since not all educational institutions have the necessary equipment. But ideally there should be at least a small laboratory, but a laboratory for implementing the planned practice. The work can be considered successful only if the student has reached a complete understanding of the material and has received specific knowledge that he can later apply in practice. In order for the student to be well prepared to perform laboratory tests, the teacher usually tries to warn in advance about the upcoming task. This will increase the likelihood that students will not sit out the whole pair just like that, without working. Let’s analyze what exactly is mean the laboratory: the study in practice of any physical or chemical processes with the help of theoretical knowledge obtained during lectures; the choice of the most effective methods of work, thanks to which it would be possible to obtain a more accurate result and a concrete result; the establishment of the result of practical work, comparing it with the theory and factual material presented in textbooks; the formulation of conclusions about the work done, the detection of inconsistencies and the competent writing of a laboratory report; the correct formulation of the conclusions in accordance with the methodological development. During the practical work, the student should: strictly follow the algorithm of the laboratory work, which is described in the methodological developments; show the teacher at the end of the study their work records, which must be maintained throughout the work; issue a report on the work after its completion.
Organization of educational process
Students who like to miss classes usually do not stay in a better position, because practicing practical tasks is always much more difficult. Moreover, the teacher is unlikely to pat the student’s head, who claims a good mark, but does not want to do anything. Laboratory work is often worked out on an individual basis, which is much harder. Practical exercises are best not to miss. Imagine how easy it is for you to work if you are engaged in a complex study with the teacher, or when you have to do it alone. Therefore, many responsible students prefer not to skip such activities. Before starting the research, the teacher should familiarize the students / pupils first of all with the safety rules, then with the subject of the forthcoming work and equipment. Also for each student there should be a methodical development, according to which he will be able to correctly draw up the report, topic and purpose of the research. The teacher must make a note in the safety journal after the briefing. In addition, each student must sign in such a magazine about his passing in front of his name. Observance of these small organizational moments is very important, because if an accident occurs with a student who does not sign the journal, the teacher will at best earn a reprimand. After the briefing while working in the laboratory, the students are already responsible for themselves and for their actions, since by signing the document, they agree that they are fully acquainted with safety techniques, know how to avoid an accident and are ready to start work.
