Navigating the Classroom Divide: How Diglossia Shapes Learning Outcomes
In classrooms around the world, students bring not just their backpacks and notebooks but also their linguistic identities. For many, this means navigating diglossia—a sociolinguistic phenomenon where two distinct varieties of a language coexist, each serving different purposes. While this dual-language dynamic is culturally rich, its impact on school performance often sparks debate among educators, parents, and policymakers. Let’s explore how diglossia influences learning, the challenges it creates, and strategies to bridge gaps in academic achievement.
Understanding Diglossia: More Than Just Bilingualism
Diglossia isn’t simply about speaking two languages. It refers to situations where a “high” (H) language variety—used in formal settings like education, media, or government—exists alongside a “low” (L) variety for everyday conversation. For example:
– In Arabic-speaking countries, Modern Standard Arabic (H) is taught in schools, while regional dialects (L) dominate informal speech.
– In Switzerland, Swiss German (L) is spoken at home, but Standard German (H) is used in writing and formal communication.
This division creates a unique learning environment. Students often grow up fluent in the L variety but encounter the H variety only in academic contexts. The disconnect between their home language and the language of instruction can shape their educational journey in profound ways.
The Literacy Hurdle: When School Feels Like a Foreign Language
One of the most immediate challenges is literacy development. Imagine a child who speaks Egyptian Arabic at home but is suddenly taught to read and write in Modern Standard Arabic. The two varieties differ significantly in vocabulary, grammar, and pronunciation. Research in countries like Egypt and Morocco shows that students in diglossic environments often take longer to achieve reading fluency compared to peers in monolingual systems.
A study published in the Journal of Child Language found that Arabic-speaking children scored lower on phonological awareness tasks—a key predictor of reading success—when tested in the H variety. This isn’t due to lower intelligence but rather the cognitive load of deciphering a less familiar linguistic code.
Classroom Participation: Silence Isn’t Always Golden
Confidence plays a huge role in learning. Students who feel insecure about their command of the H variety may hesitate to participate in class discussions or ask questions. In a Jordanian study, teachers reported that students often reverted to their L dialect during group work, even when instructed to use the H variety. While this preserves cultural connection, it can limit practice opportunities for the academic language needed for exams and essays.
Furthermore, the emphasis on mastering the H variety may overshadow critical thinking. As one Lebanese educator put it, “We spend so much time correcting grammar that we forget to ask if students actually understand the ideas behind the text.”
The Standardized Testing Dilemma
Standardized tests, typically designed in the H variety, can disadvantage diglossic students. In Greece, where Katharevousa (a formal Greek variant) was historically used in education, students from rural areas—more exposed to the Demotic (L) variety—often underperformed in national exams. Even after reforms to adopt Demotic in schools, residual gaps persist due to uneven teacher training and resource distribution.
Similar patterns emerge in math and science. A 2020 UNESCO report highlighted that diglossic students in Yemen scored 15-20% lower on word problems than their monolingual peers in non-diglossic regions. The issue? Translating complex questions from H to L mentally adds an extra layer of problem-solving.
Teachers: The Unprepared Mediators
Educators themselves often grapple with diglossia. Many teachers in diglossic regions are native L speakers but were trained exclusively in the H variety. This creates a paradox: they’re expected to teach in a language they rarely use outside school. In rural Algeria, for instance, teachers frequently code-switch between Standard Arabic and colloquial Darija to explain concepts, leading to mixed messages about linguistic “correctness.”
Professional development programs rarely address this reality. A survey of Moroccan primary schools revealed that 68% of teachers felt unprepared to handle diglossia-related challenges, citing a lack of training in bilingual pedagogy.
Socioeconomic Factors: A Hidden Layer
Diglossia’s impact isn’t evenly distributed. Families with greater exposure to the H variety—through books, media, or private tutoring—often mitigate the school-performance gap. In contrast, students from low-income households rely heavily on schools to learn the H variety, placing them at a disadvantage if teaching methods are ineffective.
This socioeconomic divide is stark in countries like India, where diglossia exists in languages such as Tamil. Urban students with internet access engage with formal Tamil through online resources, while rural peers depend solely on overburdened classrooms.
Bridging the Gap: Strategies for Success
Addressing diglossia’s impact requires a mix of policy reform and classroom innovation:
1. Early Exposure to the H Variety: Introducing the formal variety through storytelling or songs in preschool can build familiarity before literacy demands escalate.
2. Biliteracy Approaches: Schools in Malta, where Maltese (L) and English (H) coexist, use “translanguaging” techniques. Students discuss concepts in their L variety first, then transition to writing in H, reducing cognitive strain.
3. Teacher Training: Programs in Tunisia now include modules on code-switching strategies, helping educators systematically blend L and H varieties without confusing students.
4. Curriculum Design: Textbooks that acknowledge diglossia, like Lebanon’s Arabic language series, include side-by-side comparisons of H and L phrases to demystify formal grammar.
5. Community Involvement: Engaging parents through workshops—like those piloted in Sudan—helps families support literacy without feeling their L variety is “inferior.”
Looking Ahead: Embracing Linguistic Diversity
The goal shouldn’t be to eliminate diglossia but to leverage it as a cultural asset. Finland’s approach to its Swedish-speaking minority offers a model: schools teach primarily in Swedish (H) but validate students’ Finnish (L) identities through multicultural projects.
By reframing diglossia as a resource rather than a deficit, schools can foster academic success while preserving linguistic heritage. After all, the ability to navigate multiple language varieties is a skill—one that, with the right support, can empower students to thrive in an increasingly interconnected world.
In the end, the conversation about diglossia and education isn’t just about language—it’s about equity, identity, and ensuring every child has the tools to unlock their potential.
