Teachers' problem

Just a few years ago, a teacher was the only source of the children’s knowledge and was considered to be the sole possessor of ultimate truth. Nowadays the situations has changed, and pupils do not need to ask their teacher a question to know the answer anymore because all of them have smartphones with the Internet.
From my point of view, this problem is of vital importance for the present-day teachers because children have access to a large amount of different information, which they sometimes are not able to filter.
To begin with, I would like to recommend that teachers assign a report as a students homework in order to make certain identify of her/his students' awareness of this topic. For this purpose, a teacher may look through as many articles as possible articles concerning the given topic both in textbooks and on the Internet.
My next recommendation is for teachers is to forbid the pupils to use the site ‘wikipedia.com,’ as the information given there often relies on dubious and unverified sources and misrepresents or alters information.
Moreover, it is important for teachers should emphasize that there must be a l list of the references links (such as dictionaries, encyclopedias, or links to websites) in every students’ report and to clearly define the number of the sources that a pupil may [must?] use in preparing for his or her report.
All in all, a teacher should learn something new every day to keep pace with the modern children actively using the Internet.
