This mixed methods study examines code switching to Darija among 45 Master 1 EFL students at Guelma University. Analyzing 150 minutes of audio recordings reveals 482 occurrences. The results clearly demonstrate that the primary trigger is lexical gaps when facing complex academic concepts (45.2%), closely followed by the need to reduce cognitive load (18.4%). Structurally, intrasentential switching strongly dominates (55%), indicating a sophisticated bilingual competence rather than a simple linguistic failure. Furthermore, quantitative data establish a direct correlation between topic complexity and switching frequency (16.1 occurrences versus 5.6). Finally, questionnaires highlight a psychological paradox: while students find this practice highly useful for learning (4.2 out of 5), they simultaneously experience strong feelings of embarrassment (3.8 out of 5). Thus, this phenomenon emerges as an effective compensatory strategy, not a linguistic deficit, which implies an urgent pedagogical adaptation to destigmatize this natural approach within the Algerian higher education English language system.
