Educational technology - previously published content?
Hello Sergy2018, my apologies if that assumption is wrong, but has the added content been previously published somewhere else? Please note, that Wikipedia can't accept text from other sources or even text, that you yourself have published elsewhere (unless you or the copyright owner are willing to grant a completely free license for all usages of this text). Contributions from topic experts are greatly appreciated, but you shouldn't copypaste your own research 1:1 into Wikipedia. The edit's formatting and phrasing seem to come from an academic essay or study, and would need to be rephrased for an encyclopedic usage (aside from the mentioned copyright concern).

Also, you'll find some information about Wikipedia's referencing system at WP:REFB: references are usually not added as inline-text, but with tags directly after the verified sentence(s). I have reverted the addition for now (it is still visible in the article's "history" tab), but please feel free to ping me for further clarification, or if you need any other advice about editing in Wikipedia. I'd be glad to help. Best regards. GermanJoe (talk) 12:13, 27 December 2017 (UTC)
