“…In terms of the types of argumentative elements, as shown in Tables 4 and 5 , except for qualifiers, the types of argumentative elements in the experimental group have been greatly improved in the post test compared with the pre-test (Claim 1.32–1.35, Qualifier 1.28–1.08, Reason 0.99–1.18, Evidence 0.84–1.12, Warrant 1.04–1.14, Counterargument 0.37–0.69, Rebuttal 0.35–0.65), which shows that the interventional teaching ]not only makes a relatively comprehensive contribution to the generation of the number of argumentative elements in writing ( Nussbaum, 2002 , 2008 ; Liu & Stapleton, 2020 ), but also has a positive impact on the diversity of the output of argumentativr elements., In the control group, the situation is different (Claim 1.38–1.39, Qualifier 1.06–0.86, Reason 0.86–1.00, Evidence 0.76–0.74, Warrant 0.99–1.00, Counter argument 0.32–0.31, and Rebuttal 0.36–0.34) Only the types of reason and evidence have slight improvement, other types have declined. The higher the students' writing performance, the less the number of qualifiers they write ( Yang, 2022 ).…”
