Disciplinary knowledge aims at expertise while interdisciplinary education drives learners to brainstorm from multiple perspectives. In other words, interdisciplinary education reinforces the idea of salad bowl that preserves multiplicity of knowledge in a single pot. In Bangladesh, therefore, where learning English has an unparallel importance, exploring other branches of knowledge confronts the challenge of time and effort management at times. Learning English is essential to communicate with the world, but learning it combining with other disciplines can be more effective. To assess the practicality of implementing an interdisciplinary English language classroom, the study here has focused on Grammar Translation Method (GTM) and Communicative Language Teaching (CLT), mostly applied methods in Bangladesh's classrooms, among other methods and approaches of foreign language learning. The study, however, has tried to transform certain activities from above-mentioned methods and later combine them with questions from the discipline of History to observe whether such combination is possible or not. Resultantly, it appears that the selected activities can successfully be transformed into interdisciplinary format which compels the study to recommend adopting an interdisciplinary method in Bangladesh's English language classrooms on a short scale initially.
