Editorial.

This document is an editorial introducing the first special issue of Language, Context & Text. It includes a previously unknown paper on language education by Michael Halliday, introduced by Amy Tsui. The paper provides insights into Halliday's thoughts on the applicability of Systemic Functional Linguistics (SFL) to language education. Additionally, the editorial republishes an earlier paper by Halliday on the concept of "educational linguistics" from 16 years prior. The paper includes a response by Gunther Kress, which offers a valuable perspective on the development of multimodality theory and research. [Extracted from the article]
