Cross-didactics is a new term introduced by Dr. Paschalis Chliaras in order to meet the needs of his research concerning the “Concurrent Teaching of Two Related Languages in the Same Classroom”. It is the theory and practical application of teaching two similar language systems concurrently, which interact and affect both the linguistic performance and the linguistic development of the individual concerned. This typically refers two similar languages, for example, the influence of Italian or an Italian native speaker who is learning Spanish, French, Portuguese, Romanian or even English.
The theory of Cross-didactic Learning method focuses on the baseline cross-linguistic knowledge students acquire and seeks to improve upon and convey this information. It also refers to the foundation or starting point in a lesson plan consisting of concurrent teaching of two related languages in the same classroom, where the overall objective is cross-linguistic and multicultural awareness. An appropriately educated teacher functions in this role as an authoritative figure, but also as both a guide and a resource for students.
