Navigating the Classroom Challenge: How Language Variations Shape Learning Outcomes
In many parts of the world, students walk into classrooms carrying not just backpacks and textbooks but also a complex linguistic reality: diglossia. This term, coined by linguist Charles Ferguson in 1959, refers to a situation where two distinct varieties of a language coexist in a society. One is typically the “high” variety, used in formal settings like education, media, or government, while the “low” variety is reserved for casual, everyday communication. Think of Classical Arabic versus colloquial dialects in the Middle East, or Standard German juxtaposed with Swiss German in Switzerland. While diglossia reflects rich cultural heritage, its impact on school performance often sparks debate. How does this linguistic duality shape a child’s ability to learn, participate, and succeed academically? Let’s explore.
The Cognitive Hurdle: Switching Between Two Worlds
Imagine a child raised speaking a regional dialect at home—say, Egyptian Arabic—who suddenly encounters textbooks and lectures in Modern Standard Arabic (MSA). While both are forms of Arabic, they differ significantly in vocabulary, grammar, and pronunciation. For young learners, this isn’t just about translating words; it’s about rewiring their brains to process an entirely unfamiliar structure. Studies in countries like Egypt and Morocco reveal that students in diglossic environments often struggle with reading comprehension and writing fluency. Why?
The “high” language taught in schools is rarely spoken outside academic or official contexts. This creates a disconnect between classroom instruction and real-life communication. A student might excel in conversational Arabic but stumble over MSA verb conjugations during exams. The mental effort required to navigate both systems can slow down learning, especially in subjects like math or science, where precise terminology matters. Over time, this cognitive load may lead to frustration, disengagement, or even the perception that the “school language” is elitist or inaccessible.
Identity and Participation: Whose Language “Counts”?
Language isn’t just a tool for communication—it’s tied to identity, culture, and self-expression. In diglossic societies, the “high” variety often carries prestige, while the “low” variety is seen as informal or even inferior. When schools prioritize the formal language, students who grow up speaking the vernacular at home may feel their linguistic identity is undervalued. This subtle messaging can erode confidence.
For example, in Greece, the historical tension between Katharevousa (a formal, archaic variant) and Demotic Greek (the everyday language) once created classroom divides. Students from rural areas, more familiar with Demotic, often felt marginalized when teachers emphasized Katharevousa. Similar patterns emerge in Tamil-speaking regions of India, where literary Tamil dominates textbooks but differs sharply from spoken dialects. When children sense their home language isn’t “good enough” for academic success, they may withdraw from class discussions or avoid asking questions, fearing judgment.
Bridging the Gap: Teaching Strategies That Work
The challenges of diglossia aren’t insurmountable. Educators worldwide are experimenting with methods to ease the transition between language varieties while honoring cultural roots. One approach is translanguaging, where teachers intentionally blend both languages in lessons. A math teacher in Lebanon, for instance, might explain a concept in colloquial Lebanese Arabic first, then reinforce it using MSA terms. This validates the student’s native dialect while gradually building fluency in the formal register.
Another strategy involves adapting teaching materials. In Malta, where Maltese (the vernacular) and English (the formal language) coexist, schools use bilingual textbooks. Students learn science or history in English but discuss concepts in Maltese during group activities. This balances the need for global academic standards with the comfort of local expression.
Professional development also plays a role. Teachers trained to recognize diglossia-related struggles can adjust their pacing, offer targeted language support, and create inclusive environments. In Paraguay, where Spanish and Guarani are both official languages, workshops help educators integrate Guarani vocabulary into Spanish lessons, reducing the “us vs. them” dynamic between home and school languages.
Policy and Perception: Rethinking What “Success” Means
Beyond the classroom, systemic change is crucial. Policymakers must confront a critical question: Should schools prioritize fluency in the “high” language at all costs, or is there value in embracing linguistic diversity? Finland’s education system, renowned for its equity, offers a clue. While Finnish and Swedish are both national languages, schools in Swedish-speaking regions teach primarily in Swedish, ensuring students build literacy in their mother tongue before mastering Finnish. This approach correlates with Finland’s consistently high PISA scores.
Similarly, Singapore’s bilingual policy balances English (the lingua franca) with mother tongues like Mandarin or Tamil. By valuing both languages, schools reduce the stigma around the “low” variety and foster pride in multilingualism.
However, reforms face resistance in societies where the “high” language is deeply entrenched in tradition. In some Arab countries, for instance, proposals to teach early grades in colloquial dialects have sparked controversy, with critics fearing a loss of cultural unity. Yet research suggests that initial literacy in a familiar dialect can actually enhance later mastery of the formal language. It’s a reminder that flexibility, not rigidity, leads to better outcomes.
The Bigger Picture: Language as a Gateway, Not a Barrier
Diglossia’s impact on education isn’t inherently negative. When handled thoughtfully, linguistic diversity can sharpen cognitive flexibility and deepen cultural appreciation. Bilingual students often outperform monolingual peers in problem-solving and multitasking, skills amplified when navigating diglossia.
The key lies in reframing the narrative: Instead of viewing the “low” variety as a hurdle, educators can treat it as a bridge. By acknowledging the legitimacy of both languages, schools empower students to code-switch confidently—whether drafting an essay in the formal register or debating ideas in their home dialect. This balance not only improves academic performance but also nurtures well-rounded individuals proud of their heritage.
In the end, the goal isn’t to eliminate diglossia but to harness its potential. When classrooms become spaces where all languages are respected, students don’t just learn through language—they learn about language, developing skills that serve them far beyond report cards. After all, education isn’t just about mastering a curriculum; it’s about equipping young minds to thrive in a beautifully complex world.
