This paper uses an argumentative approach.
実証的 means 'empirical' or 'based on actual evidence', often from experiments or data, whereas 論証的 focuses on logical argumentation and proof.
Compound of 論証 (proof, demonstration) + 的 (-like, -ic). The exact historical derivation is uncertain, but the word follows a common pattern of forming adjectival nouns from Sino-Japanese compounds.
