Language learning is one of the most complex cognitive and social achievements that human beings are capable of — and one of the most imperfectly taught subjects in formal schooling. For most of the twentieth century, foreign language teaching in schools was organized around the Grammar-Translation Method (students study grammatical rules and translate texts between languages) and later the Audiolingual Method (students drill sentence patterns until they are automatic). Both approaches produce students who know considerable amounts about the target language but who cannot use it for genuine communication — who can conjugate verbs accurately but cannot order a meal, hold a conversation, or read authentic texts in the language.
The revolution in language teaching — precipitated by Stephen Krashen's Input Hypothesis in the 1970s-80s, Michael Canale and Merrill Swain's communicative competence framework, the ACTFL Standards movement, and more recently Michael Long's task-based language teaching and Bonny Norton's identity theory of language learning — has fundamentally shifted the understanding of what language teaching should accomplish and how. Language is not a system of rules to be memorized but a social practice to be engaged in; language learning is not a cognitive accumulation process but a social identity process; and language teaching is most effective when it creates conditions for genuine communicative engagement in meaningful contexts rather than drilling decontextualized forms.
Research Foundations of World Languages and Foreign Language Education
Stephen Krashen: The Five Hypotheses of Second Language Acquisition
Stephen Krashen (University of Southern California) developed the most influential theoretical framework in second language acquisition research — a set of five interrelated hypotheses that have shaped language teaching worldwide:
Hypothesis 1 — The Acquisition-Learning Hypothesis: Krashen distinguishes between two distinct processes: acquisition (the subconscious process through which we develop language competence, identical to the process children use to develop their first language — through meaningful exposure to language in communicative contexts) and learning (the conscious study of grammar rules and forms). Acquisition produces fluent, natural language use; learning produces knowledge about language that can be applied deliberately but slowly. Krashen's controversial (and still debated) claim is that learning does not become acquisition — knowing a grammar rule consciously does not produce the ability to use it automatically in speech.
Hypothesis 2 — The Monitor Hypothesis: The consciously learned system functions as a "monitor" — an editing device that speakers use to check and correct output when they have time to think, are focused on form, and know the relevant rule. The Monitor is useful in writing and formal spoken contexts where time permits deliberate editing; it is not useful in natural, spontaneous conversation where the pace of communication does not allow Monitor application.
Hypothesis 3 — The Natural Order Hypothesis: Grammatical structures are acquired in a predictable, roughly invariant order regardless of instruction or first language. The order of acquisition is not the same as the order in which structures are typically taught — teaching a structure before students are developmentally ready to acquire it produces the appearance of learning (students can perform the structure on a test) without genuine acquisition.
Hypothesis 4 — The Input Hypothesis: The most influential and most debated of Krashen's hypotheses. Acquisition occurs when acquirers understand input in the target language that is slightly beyond their current level of competence — "i+1" (comprehensible input at a level just above what they can currently produce). The implication is that comprehensible input (spoken or written language in the target language that students can understand) is both necessary and sufficient for language acquisition — if students receive enough comprehensible input, acquisition will occur naturally. Instruction that maximizes comprehensible input in meaningful contexts is more effective than instruction focused on grammar study and pattern drilling.
Hypothesis 5 — The Affective Filter Hypothesis: Acquisition requires not only comprehensible input but also low affective filter — the absence of anxiety, defensiveness, and self-consciousness that block the input from reaching the "language acquisition device." High anxiety (fear of being corrected, embarrassed, or judged for errors); low motivation; and low self-confidence all raise the affective filter and block acquisition, even when comprehensible input is available. The implication for language teaching is that creating psychologically safe, low-stress, meaning-focused classrooms is not merely nice — it is a condition for language acquisition.
Michael Canale and Merrill Swain: Communicative Competence
Michael Canale and Merrill Swain (Ontario Institute for Studies in Education), in their foundational 1980 paper "Theoretical Bases of Communicative Approaches to Second Language Teaching and Testing" (Applied Linguistics), developed the communicative competence framework that launched the communicative language teaching revolution:
The Four Components of Communicative Competence:
-
Grammatical Competence: Knowledge of the linguistic code — vocabulary; morphology; syntax; phonology; orthography. Grammatical competence is what traditional language teaching focused on almost exclusively, and it is genuinely important. But it is only one component of communicative competence.
-
Sociolinguistic Competence: Knowledge of the sociocultural rules for language use — knowing what language forms are appropriate in which social contexts; understanding how register, formality, and social relationships shape language choices; knowing the social meanings of language forms beyond their literal content. A grammatically perfect sentence can be sociolinguistically wrong (using informal register with a superior; being too direct in an indirect culture; failing to use appropriate politeness markers).
-
Discourse Competence: Ability to connect sentences into coherent spoken and written texts — understanding how conversations are organized (turn-taking; topic management; opening and closing sequences); how different text types are structured (narrative; argument; description); how cohesion devices (reference; substitution; ellipsis; connectives) maintain textual coherence.
-
Strategic Competence: Ability to compensate for imperfect knowledge through communication strategies — paraphrasing; circumlocution; asking for clarification; using non-verbal communication; appealing to shared knowledge. Strategic competence is what allows language learners to communicate effectively even before they have complete linguistic knowledge — and developing it is essential for genuine communicative confidence.
The Implication for Instruction: Canale and Swain established that language teaching must address all four competence components, not merely grammatical competence — that producing linguistically accurate but communicatively incompetent students is a failure of language education, however high their grammar test scores.
Michael Long: The Interaction Hypothesis and Task-Based Language Teaching
Michael Long (University of Maryland), in a series of landmark papers culminating in Second Language Acquisition and Task-Based Language Teaching (2015), developed two of the most influential theoretical and practical contributions to language teaching:
The Interaction Hypothesis: Long proposed that while Krashen's comprehensible input is necessary for acquisition, the negotiation of meaning that occurs in conversational interaction — when communication breaks down and interlocutors work to restore comprehension through repetition, modification, clarification requests, and confirmation checks — is particularly facilitative. In these moments of negotiated meaning, learners receive comprehensible input tailored to their individual comprehension difficulties, and their attention is drawn to the specific linguistic features that caused the communication breakdown. Interaction is not merely input delivery but a uniquely effective process of individualized input + feedback + noticing.
Task-Based Language Teaching (TBLT): Long's most practically influential contribution. Task-Based Language Teaching organizes instruction around communicative tasks — activities in which language is used as a means to accomplish a real communicative goal rather than as an object of study. TBLT tasks:
- Have a real communicative purpose (not language practice for its own sake)
- Require using language to accomplish a non-linguistic outcome
- Create genuine information gaps (one speaker has information the other needs)
- Involve meaning negotiation rather than form-focused exchange
Task Types: Long categorized tasks from real-world language use — what do people actually do with the target language? — and argued that instruction should prepare students for the specific tasks they will need to perform in the real world. Different learner groups need different task curricula: tourists need different tasks than business executives; heritage language learners need different tasks than academic language learners.
Form-Focused Instruction within TBLT: Long's research documents that pure meaning-focused instruction without any form attention leaves important linguistic features unacquired. His solution is "focus on form" — brief, reactive teacher attention to specific linguistic features that arise from communicative tasks, drawing learners' attention to form in the context of meaning rather than outside it.
Bonny Norton: Identity, Investment, and Imagined Communities
Bonny Norton (University of British Columbia), in Identity and Language Learning: Gender, Ethnicity and Educational Change (2000, second edition 2013) and numerous articles, developed the most influential social theory of language learning, arguing that investment — the social and identity-based dimension of motivation — is as important as cognitive capacity in determining language learning outcomes:
Identity in Language Learning: Norton argues that language learning is always also an identity construction process — learning a new language means constructing a new identity, positioning oneself in relation to new social communities, and negotiating who one is and who one might become in the target language. Language teachers who overlook the identity dimension of language learning miss one of the most powerful forces shaping their students' language development.
Investment vs Motivation: Norton distinguishes between motivation (a psychological construct concerned with learners' cognitive and affective orientations toward the learning task) and investment (a sociological construct concerned with learners' relationship to the social communities represented by the target language and with what they stand to gain or lose by identifying with those communities). A learner may be highly motivated to learn a language in the abstract but uninvested if they do not see themselves as belonging to or being accepted by the communities that use it.
Imagined Communities: Drawing on Benedict Anderson's concept, Norton argues that language learners invest in learning a language in relation to "imagined communities" — communities of users they imagine belonging to in the future. A student who imagines themselves as a future member of a global scientific community, or as someone who will work internationally, or who will be able to communicate with beloved family members in their heritage language, invests differently in language learning than a student who sees the target language as having no connection to their imagined future self.
Implications: Norton's framework implies that language education must attend to the identity investment dimension of language learning — creating conditions in which students can imagine themselves as legitimate members of target-language communities; addressing the social barriers (racism; discrimination; gatekeeping) that prevent learners from accessing target-language communities; and using pedagogical approaches that honor and build on learners' existing identities rather than requiring them to abandon their home identities to enter the target-language community.
Zoltan Dörnyei: The L2 Motivational Self System
Zoltan Dörnyei (University of Nottingham), in The Psychology of the Language Learner (2005) and Motivational Strategies in the Language Classroom (2001), developed the most comprehensive contemporary framework for understanding and developing language learning motivation:
The L2 Motivational Self System: Dörnyei's framework identifies three components of language learning motivation:
-
The Ideal L2 Self: The vision of oneself as a proficient user of the target language — who one imagines becoming in the language. The Ideal L2 Self is the most powerful motivational force in language learning: students who have a vivid, elaborate, and personally compelling vision of their future multilingual selves work harder, persist longer, and achieve more. The pedagogical implication is that language teaching should actively develop students' visions of their multilingual future selves.
-
The Ought-To L2 Self: The attributes one believes one should have as a language learner — driven by external obligations, social expectations, and the desire to avoid negative outcomes. Ought-To motivation produces language study behavior but does not generate the intrinsic engagement and creative risk-taking that Ideal L2 Self motivation does.
-
The L2 Learning Experience: The immediate motivational influences of the learning experience itself — the quality of teaching; the interest of the materials; the atmosphere of the classroom; the experience of success. L2 Learning Experience motivation explains why students who initially lack Ideal L2 Self motivation can develop it through positive classroom experiences.
Motivational Strategies: Dörnyei's extensive practical research on motivational strategies in the language classroom identifies specific teacher actions that develop motivation: creating a classroom climate of safety and acceptance; establishing student autonomy and choice; making language use feel meaningful; setting challenging but achievable goals; building students' self-confidence; and most powerfully, helping students develop their Ideal L2 Selves through guided imagery, future-self exercises, and role models of multilingual achievement.
Ofelia García: Translanguaging
Ofelia García (City University of New York), in Bilingual Education in the 21st Century: A Global Perspective (2009) and Translanguaging: Language, Bilingualism and Education (2014, with Li Wei), developed the translanguaging framework that has most significantly challenged traditional conceptions of multilingual education:
Translanguaging: The term translanguaging (originally coined by Cen Williams in Welsh; developed theoretically by García) refers to the flexible use of multilingual resources as a unified linguistic repertoire, rather than the switching between separate, fixed language systems. Translanguaging rejects the view that bilinguals and multilinguals have two or more separate languages (French; English; Spanish) that they switch between; instead, it proposes that multilingual speakers have a single, integrated linguistic repertoire that includes elements associated with different named languages, and that they deploy these resources fluidly in response to communicative needs.
Translanguaging Pedagogy: Translanguaging pedagogy deliberately leverages students' full linguistic repertoire — all the languages they know — as a resource for learning, rather than restricting instruction to the target language. In a translanguaging classroom: students are encouraged to use their home languages as cognitive resources when thinking through difficult concepts; multimodal resources in multiple languages are used as comprehension supports; students translate, compare, and make connections across languages as a learning strategy; and the additive goal (adding a new language to an already rich linguistic repertoire) is foregrounded rather than the subtractive goal (replacing home language with target language).

Communicative Task Design and Comprehensible Input
"Design a complete Task-Based Language Teaching unit for Spanish Level 2 (Grades 8-10) — 'Living in the City: Real-World Tasks in an Urban Spanish-Speaking Context' — based on Long's TBLT framework, organized around target tasks that students actually need to perform and structured to create genuine communicative engagement at each stage. Target Task Selection: Identify the real-world tasks that Level 2 Spanish students are most likely to need in authentic Spanish-speaking contexts. For an urban, tourism, and social context: making and confirming restaurant reservations; giving and receiving directions in a city; describing symptoms and seeking medical assistance; discussing local events and making plans; narrating a past experience to a friend. Unit Focus: 'Making and Navigating Plans in a Spanish-Speaking City.' Pedagogical Tasks (building toward target task): Pedagogical Task 1 (Week 1): Role-play between friend groups — one group has tickets to a concert; they must invite others by text (written communication) specifying event, date, time, and location. Receiving friend must respond: accept and ask questions; or decline and explain why. Information gap: only the inviter knows the event details. Communicative pressure: must use future reference forms to talk about upcoming plans. Pedagogical Task 2 (Week 2): Scenario — a friend has been unavailable all week and you need to fill them in on what happened. Each student receives a card with what happened to them (had a great restaurant experience; attended a local festival; explored a new neighborhood). Partners share what happened using past narration; listener asks follow-up questions. Information gap: each student knows only their own experience. Communicative pressure: must use past tense forms to narrate completed events. Pedagogical Task 3 (Week 3): Collaborative city navigation. Pairs receive different maps with different landmarks marked. Partner A must get from point X to point Y using only spoken directions; Partner B must navigate using Partner A's directions alone (cannot look at A's map). Then reverse. Information gap: partners have different maps. Communicative pressure: must use spatial language (prepositions; directions; landmarks) accurately enough for actual navigation. Focus on Form throughout: when a specific form (subjunctive; past tense contrast) causes communication breakdown, teacher notes the form, provides brief explicit instruction and examples, students practice the specific form, then return to the task. Form is taught in the moment of genuine need rather than in isolation. Target Task Assessment (Week 4): Students engage with an unrehearsed target task scenario — they call (or role-play calling) a restaurant to make a reservation, giving specific details; they navigate a partner to a destination using spoken directions only; they describe a week's events to a native speaker or proficient classmate. Assessed on communicative success (did the task get accomplished?) and strategic competence (how well did they handle communication difficulties?). Full unit with: all pedagogical task designs; information gap activity materials; form-focused instruction notes for each task; target task assessment rubrics; authentic audio/video input materials."
"Design a complete comprehensible input curriculum framework for French Level 1 (Grades 6-9) — 'French Through Stories: Building Proficiency Through Compelling, Comprehensible Input' — grounded in Krashen's Input Hypothesis and the comprehensible input-based approaches developed by Blaine Ray (TPRS: Teaching Proficiency Through Reading and Storytelling) and Ben Slavic. The framework provides a full semester's curriculum organized around compelling, culturally rich narratives at appropriate input levels. Comprehensible Input Principles: Every text, activity, and interaction is designed to be understandable to students at their current level (i+1) — challenging but not incomprehensible. Comprehensibility is achieved through: repetition of new words within context (new vocabulary recycled dozens of times across the input rather than studied in isolation); visual and contextual support; simplified syntax; and teacher adjustment based on student comprehension signals. Affective Filter considerations: stories are engaging, funny, or emotionally resonant — never boring; classroom culture is acceptance-based (errors are natural; communication matters more than accuracy); no student is put on the spot in ways that raise anxiety. Curriculum Structure: Month 1 — Class-created stories: Teacher co-creates stories with the class in French, establishing a few high-frequency vocabulary items (wants; has; goes; is; likes) and building student familiarity with French sound-symbol correspondence through engaging, student-generated content. Students make real decisions about story content within structures the teacher provides: 'Il/Elle veut un/une ___' [He/She wants a ___] — students decide what. The resulting class story is read, discussed, illustrated, and recycled multiple times. Month 2 — Reader Stories: Class reads simple illustrated readers (e.g., TPRS Publishing or teacher-created level-appropriate texts) about French-speaking characters in culturally authentic contexts. Comprehension discussion in target language: 'Who is this person? Where are they? What do they want? What problem do they have? What happens?' Month 3 — Cultural Stories and Authentic Texts: Students engage with simplified authentic texts (simplified versions of real French legends; accounts of historical events; news summaries) with visual and vocabulary supports. Cultural integration: every story unit includes cultural content (French-speaking regions and cultures represented in the stories; music; food; cultural practices). Month 4 — Extended Reader: Class reads a longer extended reader (novel-length text written at appropriate input level with engaging story) over several weeks. Extended reading develops reading fluency, sustained comprehension, and deep vocabulary acquisition through massive exposure. Full framework with: lesson structures for each month; comprehension questions at multiple levels; discussion facilitation protocols; error response guidance (comprehension-focused, not accuracy-focused); assessment design (comprehension-based, not grammar test-based); family communication about the approach."
Language Identity and Motivational Development
"Design a complete L2 Motivational Self System development program for a Mandarin Chinese Level 3 class (Grades 10-11) — 'My Mandarin Future: Building the Vision That Drives Language Growth' — grounded in Dörnyei's Ideal L2 Self framework. The program runs as a parallel track alongside regular language instruction, developing students' motivational investment in Mandarin through identity, vision, and community connection activities. Program Philosophy: Research on language learning motivation consistently shows that students with a vivid, personally compelling vision of their future multilingual selves — who can clearly imagine and feel what it would be like to use the language competently in contexts that matter to them — work harder, persist longer, and achieve more. This program deliberately develops that vision. Component 1 — Vision Development (Month 1): Exercise 1: Multilingual Role Model Research. Students identify two or three people who use Mandarin in ways they find compelling or interesting — not necessarily celebrities; possibly a family member, community member, professional, or public figure. Students research and present on: How does this person use Mandarin? In what contexts? For what purposes? What has knowing Mandarin enabled for them? Exercise 2: Ideal L2 Self Guided Imagery. Using a relaxation induction and guided imagery script, students mentally travel five years into the future and observe themselves using Mandarin in a context that matters to them. The imagery is detailed: where are you? Who are you with? What are you doing? What are you saying? How does it feel? Students record the experience in writing. Exercise 3: Ideal L2 Self Portrait. Using any medium (art; writing; collage; multimedia), students create a portrait of their Mandarin-using future self. Students share with the class; teacher responds to each portrait with genuine engagement and elaboration. Component 2 — Community Connection (Month 2): Students connect with real Mandarin-using communities: language exchange partners (through the school district's connections or online platforms); Mandarin-speaking community organizations; local Chinese-heritage cultural events; online communities centered on topics students care about (gaming; art; music; film; sports) in which Mandarin is used. Reflection: how does contact with real Mandarin-speaking communities affect your vision of your Mandarin-using future self? Component 3 — Progress Visibility (Months 3-4): Students maintain a 'language growth record' — documenting evidence of growth in their ability to communicate in Mandarin. Growth is defined communicatively: 'I had a three-minute conversation with my language exchange partner about my favorite music' — not 'I got 90% on the vocabulary test.' Monthly comparison: what could I do last month that I couldn't do the month before? Celebration of genuine communicative growth. Component 4 — Capstone Vision Project (Final Month): Students produce a 'My Mandarin Future' multimedia presentation: who I am as a Mandarin learner; who I imagine myself becoming; how I will use Mandarin in my life; what my current growth trajectory suggests about my future; one concrete commitment to continuing Mandarin beyond this class. Presented to the class and (optionally) to a community audience of Mandarin-speaking community members. Full program with: all vision development exercise designs; role model research protocol; guided imagery script; community connection facilitation guide; growth record template; capstone project design; assessment framework (assessing vision and investment alongside language skills)."
Classroom Scenario: Nour's Language Education in Ramallah, Palestine
Nour Khalid Barakat teaches English as a foreign language and Arabic language arts at a secondary school in the Al-Bireh neighborhood of Ramallah — the de facto capital and largest city of the Palestinian Authority, located in the central West Bank hills. Palestine is an ancient land with one of the world's longest and most continuously inhabited cultural histories: the site of some of humanity's earliest urban settlements; the birthplace of three world religions; and a land whose people have maintained cultural identity and continuity through centuries of conquest, occupation, displacement, and extraordinary hardship. Contemporary Palestinian life is shaped by the ongoing conditions of the Israeli-Palestinian conflict: movement restrictions; economic constraints; interrupted education due to conflict or closures; and the profound psychological burden of living under occupation.
Palestine's Multilingual Context: Palestinian students in the West Bank navigate a complex multilingual reality: Arabic (Modern Standard Arabic for formal education and writing; Palestinian Arabic dialect for everyday life); English (taught from early grades as a foreign language and essential for higher education and international communication); Hebrew (increasingly important for economic and practical reasons in the West Bank context); and for some students, additional languages of diaspora connection (French; German; Swedish) through family members living abroad. Palestinian language education is thus not merely a school subject but a survival skill set with direct implications for economic opportunity, civic participation, and international connection.
Nour's Approach to Language Education: Nour has developed a language program that centers Palestinian students' multilingual reality and their imagined futures — explicitly using Dörnyei's L2 Motivational Self System to develop students' vision of themselves as English-using global citizens, while maintaining deep commitment to Arabic linguistic and cultural identity. She uses Norton's identity investment framework to connect English language learning to Palestinian students' aspirations for international connection, advocacy, and participation in global conversations about their own situation.
EduGenius for Palestinian Language Education: Nour uses EduGenius at edugenius.app to generate communicative task designs centered on authentic Palestinian English-use contexts (international advocacy; university application; professional communication); comprehensible input materials that include Palestinian voices and narratives in English; Ideal L2 Self vision development activities that help Palestinian students see themselves as English-using global voices; translanguaging frameworks that honor the full Palestinian multilingual repertoire; and Arabic language arts curriculum designs grounded in the richness of Classical and Modern Standard Arabic literary tradition.
Key Takeaways
- Krashen's five hypotheses — particularly the Input Hypothesis (acquisition requires comprehensible input at i+1) and the Affective Filter Hypothesis (anxiety and low confidence block acquisition even when input is available) — explain the fundamental failure of traditional grammar-translation and audiolingual methods: they provide insufficient comprehensible input and create high-anxiety environments that raise the affective filter, producing students who know about the language but cannot use it
- Canale and Swain's four-component communicative competence framework (grammatical; sociolinguistic; discourse; strategic) establishes that language teaching must develop all four competences — that grammatically accurate but communicatively incompetent students are not a success of language education, and that strategic competence (knowing how to communicate despite gaps in knowledge) is among the most practically important competences for real-world language use
- Long's Interaction Hypothesis and Task-Based Language Teaching provide the most evidence-based practical alternative to grammar-focused instruction: real communicative tasks with information gaps, genuine communicative purpose, and opportunities for negotiated meaning create the conditions for both input comprehension and attention to form that acquisition research supports
- Norton's identity-investment theory establishes the social and identity dimension of language motivation that purely cognitive theories miss: language learning is always also identity work, and students who do not see themselves as legitimate potential members of target-language communities — or who face social barriers to community membership — are systematically disadvantaged by language teaching approaches that ignore this dimension
- Dörnyei's L2 Motivational Self System identifies the most powerful motivational force in language learning: students' vivid, compelling, personally relevant vision of their future multilingual selves. Language programs that actively develop this vision through guided imagery, role models, community connection, and growth documentation produce stronger motivational investment than programs that rely only on external rewards and grades
- Nour's Ramallah classroom demonstrates that language education is inseparable from identity and aspiration: for Palestinian students navigating a complex multilingual reality, English language education is most powerful when it explicitly connects to their visions of global participation, international voice, and professional opportunity — an application of Dörnyei's Ideal L2 Self framework with urgent, real-world stakes
Frequently Asked Questions
How do I balance communicative fluency and grammatical accuracy in my language classroom — between students who can communicate freely but make many grammatical errors and students who are grammatically accurate but too afraid of error to actually communicate? This is the central tension in language teaching that every practitioner must navigate, and the research provides clear direction even if the classroom implementation requires constant judgment.
The research consensus is that for beginner and intermediate learners, communicative engagement and comprehensible input should take clear priority over accuracy — for the simple reason that you cannot correct someone's grammar if they are too anxious to speak, and that the massive exposure to comprehensible input needed for acquisition cannot happen if every utterance stops for correction. Error correction that interrupts communication raises the affective filter and prevents the very acquisition process it aims to improve.
However, the evidence also clearly shows that purely meaning-focused instruction without any attention to form produces "fossilized" errors — grammatical errors that become so entrenched that they resist later correction. Long's "focus on form" solution is the most evidence-supported approach: attend to form reactively (when communication breaks down because of a grammatical error or when a specific form is clearly needed for the task) rather than proactively (stopping communication to drill grammar rules). Brief, communicatively embedded corrections — recasting a student's error in the correct form as part of a natural response — are more effective than explicit corrections that interrupt communication.
For students who are fluent but inaccurate: provide more writing tasks (where the Monitor can function); use pushed output tasks that require specific forms; use focus on form rather than focus on forms; and address the role of accuracy in specific real-world contexts (job applications; academic writing; formal speech) rather than treating accuracy as an end in itself.
