  • The coronavirus pandemic has forced universities to change-over to coolness learning. essay writing service plagiarism free thesis paper essay checking service.
    But what is happening today can be called an emergency delivery of content to audience members in isolation . Most of academies and the teachers themselves were not ready for the transition to 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 people has never utilized remote video services to take part in webinars or video conferences in the past three years.
    But professors are not required to own online learning technologies. They were simply not prepared for this, although education and its modern methods are the main function of universities. 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 strange. Therefore, the resourcefulness with which educators adapt to the remote format is commendable.

    Sometimes it is funny. Colleagues from regional academies told that some professors asked to write summary by hand and send them scans for verification.Now, people communicate remotely in real time thanks to digital technologies, students can “raise their hands” with one button, they can write with a finger on a tablet as on a blackboard, and they are told: “Please write a handwritten lectures 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. Although remote physical education training 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 anywhere anywhere.

    University professors are faced with a lack of guidance and problems in dealing with organizational matters. Some of them conduct lessons on Skype, some of them -in Zoom, some of them only sends tasks to WhatsApp. Some professors record lessons on a webcam and send them to students. The quality of such materials is very low, and it is quite difficult to perceive them. At least because the videos 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 require 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 get an educational experience on campus, but they will get grades, even formal ones.
    a thesis for an essay should
    Online learning does not have these disadvantages, because it is based on a carefully designed learning process in an electronic information and educational environment. Professors 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.
