1. Research shows that young children can learn two languages simultaneously when exposed to both languages daily at home. The early childhood years from ages 3-7 provide an optimal period for second language acquisition. 2. For young children to best acquire a second language, the conditions should resemble a home environment where two languages are used daily, with a focus on social interaction. This allows children to develop language through physical interaction, as well as listening and responding to vocal tones and gestures. 3. Teachers can promote second language development in young children by using strategies intuitively used by parents, such as simplified speech, frequent repetition, expanding on the child's utterances, and creating a welcoming environment where children feel secure practicing the new language.
