In the past, some people thought that code switching, the “use of elements from two languages in the same utterance or in the same stretch of conversation” (Genesee, Paradis, & Crago, 2004, p. 91), was evidence of confusion or even disability. Now it is well documented that code switching is a reflection of cognitive and communicative competence (Genesee et al., 2004). This resource was created to help early childhood educators develop their knowledge about code switching and implement strategies for supporting young multilingual code switchers. It was designed as a workbook with exercises and sample answers to support learning and practice.
