The coronavirus pandemic has studied universities to switch to haughtiness learning. cheapest essay writing service write a good thesis statement low price essay writing service.
But what is happening nowadays can be called an emergency delivery of content to listeners in isolation . A lot of varsities  and the teachers themselves were not ready for the teach online. According to a 2019 HSE study, University educators with an academic degree rate their level of proficiency in remote technologies at 3.2 points out of five. One in four persons has never utilized remote video services get  in webinars or video conferences in the past three years.
But educators are not required to own online learning technologies. They were simply not ready for this, although education and its modern methods are the main function of colleges. Try to oblige the surgeon to do their work from home. Let him explain to the patient via Skype how to remove his appendicitis. It sounds absurd. Thus, the resourcefulness with which professors adapt to the remote format is commendable.

Sometimes it is funny. Colleagues from regional academies said that some professors asked to write lectures by hand and send them scans for according.In present, people communicate remotely in real time thanks to new digital technologies, students can "raise their hands" with a single button, they can write with a finger on a tablet as on a blackboard, and they are told: "Please write a handwritten abstract and send the scan." Or, for example, this case: a physical education teacher asked students to shoot five-minute videos where they show physical exercises. In spite of the fact that remote physical excercises can be more originative, for example, you can make a selection of ready-made videos on YouTube, find checklists in the official domain, and teach them to play sports in self-isolation, while you can't go outside anywhere.

University teachers are faced with a lack of guidance and problems in dealing with organizational matters. Someone educate on Skype, some of them -in Zoom, some of them only sends tasks to WhatsApp. Some educators record lectures on a webcam and send them to their students. The quality of such materials is very low, and it is hard to perceive them. At least because the content on YouTube, which students are used to, is shot and edited professionally and the viewer is spoiled by the quality of video materials.
There are also problems with monitoring attendance. Some educators ask you to put a " + " in the chat, others ask  you to turn on Webcams and take screenshots of students. Against the background of all the misunderstandings and problems, one element of academic life remains unchanged - assessment. Students don't study on campus, but they will get grades, even formal ones.

Learning online from home does not have these disadvantages, because it is based on a carefully designed learning process in an electronic information and educational environment. Teachers have instructions, manuals, memos,checklists, templates for emails and notifications, and even presentations. Everything is thought out here-from the screen saver before the lesson to the slide with homework.
