Hey, mate ur question is not very clear to me

It mean  additional, or one more, or sometimes one less. it's a matter of the increment, a little more or a little less, that's what the  margin  refers .

This is a question about plagiarism.the original source material is "but what are reasonable outcomes of the influence of global processes on education? while the question of how global processes influence all aspects of education (and who controls these forces) is multidimensional and not completely testable, there appear to be some theories of globalization as it relates to education that can be empirically examined.references: rutkowski, l., & rutkowski, d. (2009). trends in timss responses over time: evidence of global forces in education?   educational research and evaluation, 15(2), 137-152.and the student version is given above in the question.and i think this is the paraphrasing plagiarism. because there is similar text written in the students version just in his own words and paraphrase means to write something in your own words.
