Key Terms to Review (18)
Communicative language teaching: Communicative language teaching (CLT) is an approach to language instruction that emphasizes interaction as the primary means of learning a language. In this method, learners engage in meaningful communication through speaking, listening, reading, and writing activities, which reflect real-life situations. CLT focuses on developing communicative competence, which includes not only grammatical proficiency but also the ability to use language effectively in various contexts.
Critical Period Hypothesis: The Critical Period Hypothesis suggests that there is a specific window of time during which language acquisition occurs most easily and effectively, typically believed to be from early childhood until puberty. This idea connects to various aspects of language learning, including how age affects second language acquisition, the cognitive and biological foundations of language, and individual differences in language skills.
Cultural Immersion: Cultural immersion refers to the process of fully engaging with and experiencing a culture through direct interaction, participation, and exposure to its language, customs, and social norms. This deep involvement often enhances understanding and appreciation of the cultural context, which can significantly impact language learning and communication skills.
Formative Assessment: Formative assessment refers to a range of evaluation processes used to monitor student learning and provide ongoing feedback that can be used by instructors to improve their teaching and by students to enhance their learning. Unlike summative assessments, which evaluate student learning at the end of an instructional unit, formative assessments are typically conducted during the learning process and aim to identify areas where students may need additional support or intervention.
Fossilization: Fossilization is a concept in second language acquisition that refers to the phenomenon where incorrect language usage becomes a permanent part of a learner's linguistic repertoire. This occurs when certain errors are not corrected over time, leading to ingrained habits that are resistant to change. Fossilization highlights the challenges learners face in achieving native-like proficiency and suggests that some errors may persist despite exposure to the target language and attempts at correction.
Input Hypothesis: The Input Hypothesis is a theory in second language acquisition that suggests learners acquire language most effectively when they are exposed to input that is slightly beyond their current level of proficiency, often referred to as 'i+1'. This theory emphasizes the importance of comprehensible input, meaning that the language input should be understandable to the learner, yet still provide a challenge to promote growth. It highlights how interaction and exposure to natural language use play crucial roles in helping learners develop their language skills.
Interaction Hypothesis: The interaction hypothesis suggests that language acquisition is facilitated through meaningful interaction and communication between learners and proficient speakers. This theory emphasizes that negotiation of meaning during conversations helps learners understand language input better, ultimately leading to more effective second language acquisition and fluency.
Interlanguage: Interlanguage refers to the evolving linguistic system that a language learner creates as they progress in acquiring a second language. This system is characterized by elements of both the learner's native language and the target language, leading to unique grammatical structures and vocabulary usage that may not conform to either language. As learners gain more exposure and practice, their interlanguage becomes more refined and approaches native-like proficiency.
Intermediate Fluency: Intermediate fluency is the stage in second language acquisition where learners can communicate with some degree of proficiency and understand complex sentences, but may still struggle with certain nuances or idiomatic expressions. This phase marks a significant transition from basic conversational skills to a more refined ability to express thoughts and comprehend more challenging content. Learners at this stage can engage in discussions, read longer texts, and produce written language, albeit with occasional errors.
Jim Cummins: Jim Cummins is a prominent educational researcher known for his work on bilingualism and second language acquisition. His theories emphasize the importance of cognitive and academic language proficiency in learning, especially in contexts where students are acquiring a second language. Cummins introduced key concepts such as Basic Interpersonal Communicative Skills (BICS) and Cognitive Academic Language Proficiency (CALP), which are essential for understanding how language learners progress in their studies and integrate into bilingual education environments.
Language Learning Strategies: Language learning strategies refer to the specific methods and techniques that learners use to improve their proficiency in a second language. These strategies can be cognitive, metacognitive, social, or affective, and they play a crucial role in how individuals acquire a new language. By employing various strategies, learners can enhance their understanding, retention, and practical use of the language.
Pre-Production Stage: The pre-production stage is the initial phase in second language acquisition, where learners are exposed to the new language but are not yet able to communicate with it. During this period, individuals focus on listening and understanding language input, while their ability to produce spoken or written language is limited. This stage is crucial as it lays the groundwork for future language development by fostering comprehension and familiarity with phonetics, vocabulary, and grammar structures.
Social Identity: Social identity refers to the part of an individual's self-concept that is derived from their membership in social groups, including aspects like race, ethnicity, nationality, and affiliation with various communities. It influences how individuals perceive themselves and interact with others, shaping language use, communication styles, and the motivation behind learning a new language. Understanding social identity is crucial in examining how learners approach second language acquisition and how cultural backgrounds impact language learning experiences.
Stephen Krashen: Stephen Krashen is a prominent linguist and educational researcher known for his theories on second language acquisition. His work emphasizes the importance of comprehensible input and interaction in learning a new language, suggesting that language acquisition occurs when learners are exposed to language that is slightly above their current proficiency level. Krashen's ideas challenge traditional views of language instruction, focusing instead on the naturalistic acquisition process.
Summative Assessment: Summative assessment is a method of evaluating student learning at the end of an instructional unit by comparing it against a standard or benchmark. It is typically used to measure the effectiveness of educational programs and student achievement, often through tests, projects, or final exams. This type of assessment helps educators determine whether students have met the learning objectives and can inform future teaching strategies.
Task-based learning: Task-based learning is an instructional approach that focuses on the use of meaningful tasks as the central component of the learning process. This method emphasizes real-life communication and practical usage of a language rather than rote memorization or grammar drills. By engaging learners in tasks that mirror authentic language use, this approach supports second language acquisition through contextual practice and enhances motivation and interaction among learners.
Transfer: Transfer refers to the influence of a person's existing knowledge, skills, or experiences from one language or context onto another language they are learning. This can manifest as positive transfer, where similarities between languages enhance learning, or negative transfer, where differences lead to errors and misunderstandings. Understanding transfer is crucial for recognizing how a learner's first language can shape their acquisition of a second language.
Younger learners: Younger learners refer to children, typically in early childhood or primary education, who are in the process of acquiring a second language. This group is often characterized by their cognitive development stages, social-emotional needs, and distinctive learning styles that differ from older learners. Understanding how younger learners engage with language acquisition can help educators tailor effective instructional strategies that align with their natural curiosity and ability to absorb new languages.
