Note: Indeed, electronic technologies expand the opportunities for obtaining education for those categories of the population who previously did not have this opportunity. This applies to people with disabilities living in remote areas who want to go through retraining or change the sphere of professional activity on parental leave without interruption. Of course, this approach increases the opportunities for professional growth of a much larger number of people than with the preservation of only traditional full-time and correspondence courses. Of the significant disadvantages of electronic technologies in education, we can note only one: they are not aimed at developing sufficient practical skills. A person who studies using remote methods should independently organize all types of practice for himself and pass them without the methodical help and supervision of teachers who are accepted in full-time education.
