Hello dear teacher, @pedrobrito2004, interesting reading.
The point is that despite everything, I could not blame the students for their lack, they were disapproved because of regulation, but in truth their action showed me the poor state in which our education system is from the initial stages, in which They are not taught that while thanks to the Internet you can consult any amount of material, you have to give credit to those who dedicated their efforts to produce the ideas and content we are consulting.
That is the big problem, in my case I am an afflicted writer and I have learned most of the things about writing here, I must be honest, and I have many things to learn yet, this is where I become fully aware of this whole matter referring to content plagiarism and those things, but it is something that is not taught in our educational system or not emphasized.
At the level of higher education it is a headache. Then, in their future professional lives, these things can have very negative effects, even with legal implications.
I would like my students to learn quickly about the subject and correct themselves on time.
