Key Questions: How do children learn their first language(s)? What are the stages involved? What factors influence language development?  Theories of Language Acquisition 1. Behaviorist Theory Theory (B.F. Skinner) Key Idea: Language acquisition is a learned behavior through interaction with the environment. Operant Conditioning: Children imitate the language they hear and receive reinforcement for correct language use. Criticism: The theory doesn't account for how children produce novel sentences or understand complex grammatical rules not directly taught. 2. Nativist Theory (Noam Chomsky) Key Idea: Children are born with an innate ability to learn language. Language Acquisition Device (LAD): A hypothetical brain mechanism that enables children to rapidly learn the rules of language. Universal Grammar: All human languages share a universal set of grammatical structures. Criticism: The theory is criticized for lacking empirical evidence and not explaining how language develops in specific cultural contexts  Theories of Language Acquisition 3. Social Interactionist Theory (Lev Vygotsky) Key Idea: Language acquisition is a social process influenced by interactions with caregivers and others. Zone of Proximal Development (ZPD): Children learn best when they are guided by more knowledgeable individuals just beyond their current level of competence. Scaffolding: Caregivers provide temporary support that helps children acquire language skills. Criticism: The theory doesn't focus enough on the internal cognitive processes involved in language acquisition. 4. Connectionist Theory Key Idea: Language acquisition is a result of pattern recognition in the input children receive. Statistical Learning: Children detect regularities in speech patterns, such as word frequency and syllable structure, to learn language. Strengths: It explains how children can learn language without explicit teaching. Criticism: It may oversimplify the complexities of language acquisition, especially when it comes to syntax.  Theories of Language Acquisition 5. Cognitive Theory (Jean Piaget) Key Idea: Language acquisition is linked to cognitive development. Stages of Cognitive Development: Children’s ability to understand language follows cognitive stages, such as sensorimotor and preoperational stages. Egocentrism and Symbolic Thought: As children develop, they move from egocentric thinking to understanding language as a tool for communication. Criticism: The theory underemphasizes the role of social interaction in language learning.  Stages of language development He proposed several stages through which children progress: Sensorimotor Stage (Birth to 2 years): Language begins to emerge as children develop object permanence and begin to understand that words represent objects and actions. However, language is still tied to immediate experiences. Preoperational Stage (2 to 7 years): Children start to use symbols and language more extensively. They engage in egocentric thinking, meaning they have difficulty understanding perspectives other than their own. Language becomes more complex but is often used in a self-centered way. Concrete Operational Stage (7 to 11 years): Children can use logic to understand the relationships between words and concepts. They can grasp more complex language structures, but their thinking is still grounded in concrete experiences. Formal Operational Stage (11 years and beyond): Adolescents develop the ability to think abstractly, allowing them to understand and use language in more sophisticated, hypothetical, and logical ways. Piaget’s theory emphasizes the importance of cognitive development in language acquisition, suggesting that language grows as children’s thinking becomes more advanced.  Theories of Language Acquisition 6. Usage-Based Theory (Tomasello) Key Idea: Language is learned through usage and experience. Construction Grammar: Children learn language by associating words and phrases with specific meanings and contexts. Social Interaction and Cognitive Processing: Both are crucial in the learning process, as children learn language by engaging with others. Criticism: Some argue that this theory doesn't fully explain the rapid and universal nature of language acquisition  Comparison of Theories Theory Key Idea Strengths Criticism Innate ability to learn Explains universal Nativist Lacks empirical evidence language language patterns Language learned Focuses on the role of Doesn't explain novel Behaviorist through reinforcement environment sentence formation Language through social Emphasizes social Insufficient focus on Social Interactionist interaction context in learning cognitive processes Explains language Pattern recognition in Oversimplifies language Connectionist learning as a process of language input complexities exposure Language linked to Links cognitive growth Underemphasizes social Cognitive cognitive development with language interaction Language learned Accounts for linguistic Doesn't fully explain Usage-Based through use and flexibility rapid acquisition experience  Stages of Language Acquisition 1. Stage 1: Pre-linguistic or Pre-verbal (babbling) Stage (0-12 months) Characteristics: Cooing and Babbling: Early vocalizations that involve repeating consonant-vowel sounds. No real words yet but babies experiment with sounds. Examples: English: Babies may produce sounds like "ba-ba," "da-da," "ga-ga." Arabic: Babies may produce sounds like "ba-ba," "da-da," "ma-ma" (common across languages). Data: English Example: "Cooing" sounds emerge around 6 weeks, with babies making repetitive vowel sounds like "ahh," "ohh." Arabic Example: Similar to English, Arabic-speaking infants also engage in babbling like "da-da" or "ba- ba."  Stages of Language Acquisition 2. Stage 2: One-Word (Holophrastic) Stage (12-18 months) Characteristics: Single-word utterances used to convey entire meanings (holophrases). Vocabulary Development: Around 50 words, usually nouns. Examples: English: A child may say "milk" to mean "I want milk." Arabic: A child may say "baba" ( )‫بابا‬to mean "father" or "I want father." Data: English Example: At 12-18 months, children may use single words such as "dog," "eat," or "up." Arabic Example: Similar usage in Arabic-speaking children, e.g., "kita:b“ ‫ كتاب‬for "book."  Stages of Language Acquisition 3. Stage 3: Two-Word Stage (18-24 months) Characteristics: Simple Sentences: Two words used together to form basic sentences. Combination of Nouns and Verbs: Simple word combinations often reflect basic syntax. Examples: English: "Big truck," "Want cookie." Arabic: "Abi: mama" ‫ أريد ماما‬meaning "I want mama." Data: English Example: "More juice," "Daddy home." Arabic Example: "Ana raah" ‫ أنا راح‬meaning "I am going."  Stages of Language Acquisition 4. Stage 4: Early Multi-word Stage (24-30 months) Characteristics: Expanded Sentences: Three or more words used together to form basic statements, questions, and commands. Increased Vocabulary: The child begins to use adjectives, pronouns, and verbs more creatively. Examples: English: "I want to go home," "That’s my dog." Arabic: "Ana raah al madresa" ‫ أنا رايح المدرسة‬meaning "I’m going to school." Data: English Example: At around 2 years, children may form sentences like “Where is mommy?” or “Give me cookie.” Arabic Example: In Arabic, children might say “Fee al bait” ‫في البيت‬meaning “In the house.”  Stages of Language Acquisition 5. Stage 5: Later Multi-word Stage (30+ months) Characteristics: Complex Sentences: Use of longer, more complex sentences that show an understanding of grammatical rules. Questions and Negation: The child starts using more complex forms of negation and asking questions. Examples: English: "Why can’t we go outside?" "I don’t want that cookie." Arabic: "Leish ma raht mama?“ ‫ ليش ما راحت ماما؟‬meaning "Why didn’t mama go?" Data: English Example: "I don’t like broccoli," "Can I play with that?" Arabic Example: "Ana shuft al film" ‫ أنا شفت الفيلم‬meaning "I saw the movie."  Stages of Language Acquisition 6. Stage 6: Refining and Mastery of Grammar (3-7 years) Characteristics: Complex Sentence Structures: Children begin to use conjunctions and relative clauses. Grammatical Errors: Overgeneralization of rules (e.g., "goed" for "went"). Mastering Syntax and Morphology: Full understanding of sentence structure and grammatical rules. Examples: English: "I went to the park, and then we ate lunch." Arabic: “Ana ʕindi kita:b ʒadid“ ‫ أنا عندي كتاب جديد‬meaning "I have a new book." Data: English Example: By age 4, children can form complex sentences like "I don't want to go because it's raining." Arabic Example: In Arabic, sentences like "Al walad jaktub" ‫ الولد يكتب‬meaning "The boy is writing" reflect growing mastery.  Factors Influencing Language Acquisition Innate Biological Mechanisms (Nativist) Example: The human brain is equipped with structures (like the Language Acquisition Device) that make learning language possible. Environmental Input (Behaviorist) Example: Exposure to spoken language from caregivers and others helps children learn words and structures. Social Interaction (Interactionist) Example: Children learn language through interaction with caregivers, peers, and social contexts. Cognitive Development (Cognitive Theory) Example: As children’s cognitive abilities grow, they are able to understand and use more complex language.  The Role of Parents and Caregivers Child-Directed Speech (CDS): Also known as "parentese," it involves exaggerated intonation, slower speech, and simple vocabulary to engage the child. Scaffolding: Caregivers provide support for language learning by adjusting their speech and interactions to match the child’s developmental stage. Example: Caregivers might say, "Look at the big red ball!" to highlight key elements of a sentence, reinforcing both vocabulary and sentence structure.  Milestones of Language Acquisition (Example Data) Age Language Milestone Example 0-6 months Cooing and Babbling "Ba-ba," "Da-da" 12-18 months First Word Production "Milk," "Dog" 18-24 months Two-word Combinations "Big truck," "Want cookie" 24-30 months Simple Sentences "I want cookie," "That’s my dog" 3-4 years Complex Sentences, Questions, Negation "I don't want that," "Where's daddy?" "I went to the park," "She is eating an 5-7 years Mastery of Grammar and Syntax apple."  Mistakes children make while learning a language Overgeneralization: Applying a grammatical rule too broadly. E.g., saying "goed" instead of "went." Morpheme errors: Misusing plural or tense markers. E.g., saying "mouses" instead of "mice" or "she runned" instead of "she ran." Omissions: Leaving out words or parts of sentences. E.g., saying "I go park" instead of "I go to the park." Overextension: Using a word too broadly. E.g., calling all four-legged animals "dog." Underextension: Using a word too narrowly. E.g., using "cat" only for the family pet, not for other cats. Word order errors: Mixing up the typical sentence structure. E.g., saying "Eat cake I" instead of "I eat cake."  The Critical Period Hypothesis (Eric Lenneberg, 1967) Core Idea: There is a sensitive period (usually early childhood) for acquiring language easily and naturally. Evidence: Children exposed to language before a certain age acquire it more easily. Late language learners (after the age of 7) often struggle with fluency and accent. Lateralization refers to the process by which certain functions, like language, become specialized in one hemisphere of the brain. In most people, language processing tends to be lateralized to the left hemisphere. The Critical Period Hypothesis and lateralization are connected because, after the critical period, the brain's ability to reorganize language functions (especially if one hemisphere is damaged) becomes less flexible, making language acquisition and recovery harder.  Bilingual and Multilingual Acquisition Key Concept: Children can acquire more than one language simultaneously. Factors Influencing Success: Amount and quality of exposure to each language. Age of acquisition. The environment and social context in which the languages are learned. Example: A child raised in a household where both English and Spanish are spoken might develop fluency in both languages by the age of 4 or 5.  Conclusion Language Acquisition is a Complex Process: It involves innate biological factors, environmental input, and social interaction. Children acquire language in stages, with their skills evolving from simple sounds to complex grammatical structures. Individual Variability: While there are common stages, individual children may progress at different rates depending on various factors like exposure, environment, and cognitive development.  Language Learning/Acquisition Course Code: 21 Instructor: Khalid Lahbibi Contact Information: [Email: [email protected]] Semester: Fall 2024 Class Schedule: Thursday/13h00-16h00 Location: Room..  Outline Introduction Language Acquisition Language Learning Key Differences Conclusion  Introduction Language learning and language acquisition are two distinct processes, each with its own characteristics and methods. Language learning and language acquisition are two terms that refer to the process of gaining language skills, but they differ in how they occur, their mechanisms, and the context in which they take place.  Language Acquisition Language acquisition refers to the natural, unconscious process by which humans learn their first language, typically during early childhood. It happens without formal instruction and is driven by interaction with the environment and caregivers. Key Characteristics: Unconscious Process: It occurs naturally and involuntarily, without explicit awareness or effort from the learner. Occurs in Early Childhood: Language acquisition generally happens during the first few years of life, Implicit Learning: The individual picks up language rules and structures naturally through exposure to spoken language in context. Social Interaction: It heavily relies on social interaction and communication with caregivers, family, and peers. Critical Period Hypothesis: The idea that there is a sensitive period (usually in early childhood) during which language acquisition occurs most easily. Example: A child learns to speak their native language (e.g., English, Spanish) by hearing it spoken around them and engaging in conversations, even without formal lessons.  Language Learning Language learning, in contrast, usually refers to the more conscious and deliberate process of learning a second (or additional) language. It often involves formal instruction and structured activities. Key Characteristics: Conscious Process: The learner is typically aware of the language they are learning and actively works on mastering it. Occurs at Any Age: Language learning can happen at any age, but it is commonly associated with older children and adults. Explicit Learning: Involves memorizing rules, vocabulary, and grammar through explicit teaching methods, such as textbooks, lessons, or classroom instruction. Less Dependent on Social Interaction: While interaction still plays a role, language learners often use structured resources like classes, apps, or textbooks. Slower and More Effortful: The process of learning a new language is typically slower and requires more conscious effort compared to acquisition. Example: An adult learning French as a second language in a classroom setting, using a textbook to study grammar rules and vocabulary, is engaging in language learning.  Aspect Language Acquisition Language Learning Consciousness Unconscious, automatic Conscious, deliberate Age of Early childhood (birth to Can occur at any age Occurrence around age 7) Natural environment Formal or structured Key Context (home, family, social environment (classrooms, Differences interaction) courses) Implicit, through Explicit, through lessons, Method interaction and exposure practice, and study Fast, especially in early Slower, especially after Speed years childhood Often non-native Native-like fluency, proficiency, can be fluent Outcome intuitive understanding but may lack native-like intuition  Conclusion While language acquisition is a natural, passive process that occurs most effectively in early childhood, language learning involves more active, deliberate study and is typically associated with acquiring additional languages later in life. Both processes are essential to how people develop and expand their linguistic abilities, but they operate through different mechanisms.  Language Learning Course Code: 21 Instructor: Khalid Lahbibi Contact Information: [Email: [email protected]] Semester: Fall 2024 Class Schedule: Thursday/13h00-16h00 Location: Room..  Outline Introduction Second/Foreign Language LearningLanguage Learning Challenges in Second Language Learning Factors Influencing Second Language Learning Feedback and Error Correction Focus on Method Conclusion  Second/Foreign Language Learning A distinction is sometimes made between learning in a “foreign language” setting )learning a language that is not generally spoken in the surrounding community) and a “second language” setting (learning a language that is spoken in the surrounding community). That is, Japanese students in an English class in Japan are learning English as a foreign language (EFL) and, if those same students were in an English class in the USA, they would be learning English as a second language (ESL). In either case, they are simply trying to learn another language, so the expression second language learning is used more generally to describe both situations.  Challenges in Second Language Learning Language Transfer: Learners may transfer grammatical rules and pronunciation from their first language, which can lead to errors in the second language. For example, a Spanish speaker might say "She have a book" because of the structure in their native language. Pronunciation: Pronunciation in a second language can be difficult, especially for learners who are past the critical period of acquisition. Interlanguage: This is the transitional phase where a learner's language is neither that of their first language nor their second language but a mixture of both. This phase can involve simplifications or overgeneralizations of grammar.  Factors Influencing Second Language Learning Age: Critical Period Hypothesis: Younger learners tend to achieve more native-like pronunciation and fluency, particularly in their first language. Older learners may find it more challenging to master pronunciation but can excel in grammar and vocabulary. Motivation: Integrative Motivation: Desire to learn a language to connect with the culture and people (often leads to more success). Instrumental Motivation: Learning for practical reasons (e.g., career, travel), which can still be effective but may not foster deep cultural engagement. Learning Environment: An immersive environment, where learners are regularly exposed to the language through interaction with native speakers or cultural exposure, significantly aids learning. Classroom learning and structured lessons also provide essential support, but interaction with the language in real-world settings is often more effective. Input: Comprehensible Input: Learners need exposure to language that is just above their current proficiency level but still understandable (often referred to as "i+1"). Interactional Input: Interaction with speakers of the language allows for real-time practice, correction, and feedback, which is crucial for development.  Factors Influencing Second Language Learning Cognitive Factors: Learners' cognitive abilities, such as memory, attention, and processing speed, affect how quickly they can absorb new language. Language aptitude: Some individuals may have a natural ability for learning languages, making it easier for them to pick up new languages First Language Influence: Language Transfer: The influence of the first language can lead to errors in the second language, such as grammatical mistakes or pronunciation challenges. Positive transfer (similarities between languages) can aid learning, while negative transfer (differences) can cause difficulties. Social Factors: Learners’ social context—such as the presence of a supportive community, peer influence, and exposure to the language in social settings—can enhance motivation and practice opportunities. Attitudes towards the language: A positive attitude towards the target language and its speakers often contributes to better learning outcomes. Learning Strategies: Effective use of learning strategies, such as practice, repetition, and mnemonic devices, helps learners internalize language more efficiently. Self-regulation: Learners who are able to set goals, monitor progress, and adjust strategies are often more successful. Exposure and Practice: Frequent exposure and consistent practice are key to reinforcing new language skills, especially in terms of speaking and listening.  Feedback and Error Correction Positive Feedback: Reinforcing correct usage helps learners recognize and internalize correct language patterns. Negative Feedback: Correcting errors can be useful, but over-correction can impede progress. Learners often make mistakes in grammar, pronunciation, and usage, which can be a natural part of the learning process.  Focus on Method Despite all these barriers, the need for instruction in other languages has led to a variety of educational approaches and methods aimed at fostering L2 learning. More recent approaches designed to promote L2 learning have tended to reflect different theoretical views on how an L2 might best be learned.  Focus on Method 1. Grammar-Translation Method Focus: Learning grammar rules and vocabulary through translation exercises. Characteristics: Classes are conducted in the students’ native language, with little emphasis on speaking and listening. Activities: Translation of texts, memorization of grammar rules and vocabulary lists. 2. Direct Method Focus: Immersion in the target language without using the students’ native language. Characteristics: Emphasizes speaking and listening skills, with grammar taught inductively. Activities: Question-answer exercises, reading aloud, conversation practice. 3. Audio-Lingual Method Focus: Developing listening and speaking skills through repetition and drills. Characteristics: Uses pattern practice and mimicry to teach language structures. Activities: Repetition drills, dialogue memorization, role-playing. 4. Communicative Language Teaching (CLT) Focus: Real-life communication and interaction. Characteristics: Emphasizes fluency over accuracy, with a focus on meaning rather than form. Activities: Role plays, group discussions, problem-solving tasks.  Focus on Method 5. Total Physical Response (TPR) Focus: Learning language through physical movement. Characteristics: Combines language learning with physical actions to enhance memory and understanding. Activities: Commands that require physical responses, such as “stand up” or “pick up the book.” 6. Task-Based Language Teaching (TBLT) Focus: Completing meaningful tasks using the target language. Characteristics: Encourages active participation and practical use of language. Activities: Planning events, solving problems, creating presentations. 7. Natural Approach Focus: Emphasizing comprehension and communication. Characteristics: Learners are exposed to language in a natural, stress-free environment. Activities: Listening to stories, participating in conversations, using visual aids. 8. Suggestopedia Focus: Reducing learner anxiety to enhance learning. Characteristics: Uses music, relaxation techniques, and positive suggestion. Activities: Listening to music while learning, role-playing, dramatizations.  Conclusion Each method has its own strengths and can be effective depending on the learners’ needs and contexts
