Introduction
Robert DeKeyser is a renowned professor of second language acquisition (SLA) and applied linguistics at the University of Southern California. His research and scholarship have significantly shaped our understanding of how people learn second languages.
Cognitive Foundations of SLA
DeKeyser's theoretical framework is based on cognitive science, which emphasizes the role of cognitive processes in language learning. According to DeKeyser, language acquisition involves the creation and modification of mental representations of language. These representations include phonological, lexical, syntactic, and pragmatic knowledge.
The Input Hypothesis
One of DeKeyser's most influential contributions to SLA is his work on the input hypothesis. This hypothesis states that learners acquire language by receiving comprehensible input that is slightly beyond their current level of proficiency. Comprehensible input provides learners with opportunities to notice and learn new linguistic forms and structures.
Processing Instruction
DeKeyser also emphasizes the importance of processing instruction in SLA. This approach to language teaching focuses on developing learners' language processing skills, such as reading comprehension, listening comprehension, and speech production. DeKeyser's research has shown that processing instruction can improve learners' overall language proficiency.
Individual Differences
DeKeyser recognizes that learners vary widely in their language learning abilities. He developed the Dynamic Model of SLA, which incorporates individual differences into the SLA process. The model suggests that learners' cognitive abilities, learning strategies, and other personal factors influence their language acquisition trajectory.
Implications for Language Teaching
DeKeyser's research has had profound implications for language teaching methodologies. His work has led to the development of teaching approaches that emphasize:
Table 1: Key Findings from DeKeyser's Research on SLA
Key Finding | Description |
---|---|
Input Hypothesis | Learners acquire language by receiving comprehensible input. |
Processing Instruction | Learners benefit from instruction that focuses on developing language processing skills. |
Individual Differences | Learners vary in their language learning abilities, and instruction should be tailored to their needs. |
Dynamic Model of SLA | SLA is a complex process that is influenced by cognitive, affective, and social factors. |
Stories and What We Learn
Story 1: A group of students taking a Spanish class initially struggled to understand spoken Spanish. However, after implementing DeKeyser's input-based approach, which focused on providing students with comprehensible input in the form of authentic videos and conversations, their comprehension skills improved significantly.
What We Learn: Comprehensible input is essential for language acquisition.
Story 2: A student taking a French class struggled to learn the correct pronunciation of French words. After participating in a pronunciation workshop that incorporated processing instruction techniques, such as practicing tongue twisters and engaging in structured pronunciation exercises, the student's pronunciation accuracy improved markedly.
What We Learn: Processing instruction can help learners improve their pronunciation skills.
Story 3: A language learner studying Mandarin Chinese became discouraged because of the challenges of learning a tonal language. However, after working with a language tutor who tailored instruction to the learner's specific learning needs, the learner's progress accelerated.
What We Learn: Individual learner differences should be considered in language teaching.
Effective Strategies for SLA

Learning a second language offers numerous benefits, including:
Conclusion
Robert DeKeyser is a leading authority on second language acquisition. His research and scholarship have provided valuable insights into the cognitive processes involved in language learning. By incorporating DeKeyser's principles into language teaching methodologies, educators can help learners achieve their language learning goals effectively.
Table 2: Benefits of Learning a Second Language
Benefit | Description |

Table 3: Effective Language Learning Strategies
Strategy | Description |
---|---|
Comprehensible Input | Learners need to be exposed to comprehensible input that is slightly beyond their current level of proficiency. |
Processing Instruction | Learners benefit from instruction that focuses on developing language processing skills, such as reading comprehension, listening comprehension, and speech production. |
Metacognitive Strategies | Learners should develop awareness of their own learning processes and employ strategies to improve their learning. |
Language Immersion | Immersive experiences, such as studying abroad or living in a foreign country, can accelerate language acquisition. |
Practice | Regular and consistent practice is essential for language learning. |
