From past to present, there has been a wide array of arguments about the implicit and explicit knowledge from many aspects of language related fields. The three different articles from various perspectives will be examined and responded briefly by focusing on their points about two knowledge systems. Before getting into details, it should be declared that it is common idea that whereas the declarative knowledge, explicit one, is related with the question of knowing what, occur without awareness, and necessities the ability of verbalizing; procedural knowledge, implicit one, has features of knowing how, having intuition and the ability of using the knowledge.
Initially, the article of, Automatization, Skill Acquisition, and Practice in Second Language Acquisition, by Robert Dekeyser and Raquel Criado mainly focus on the systematic practice by getting into details about explicit and implicit knowledge, the process of automatization and showing how all these elements are associated in each other. Their fundamental point is that what should be concentrated on the language learning is to associate the forms and meanings. Thus, practicing should be maintained by focusing on the target skills. They emphasize the importance of explicit knowledge in terms of teaching it relevantly to the context of learning, goals, and age of learners. Although the automatization which is acquired by implicit knowledge takes a long time, learners should maintain to practice and make their explicit
