Which hypothesis states that languages are learned in a specific sequence?

The Natural Order Hypothesis posits that individuals acquire languages in a predictable sequence, regardless of the age at which they begin learning. This concept, developed by Stephen Krashen, suggests that there are stages in language acquisition that are universal to all learners. For instance, certain grammatical structures are typically mastered before others, and this sequence can be observed across different languages and learners.

Understanding this hypothesis is essential for educators, particularly in inclusive classrooms, as it informs instructional strategies. By recognizing that students may be at varying stages of language development, teachers can tailor their approaches to meet the individual needs of learners, ensuring they receive appropriate support and instruction based on their current proficiency level rather than treating language acquisition as a one-size-fits-all process. This insight is particularly relevant for teaching strategies that require an understanding of how students progress in their language skills over time.
