The main idea of English medium instruction (EMI) is to combine the conventional instruction of content-area subjects with foreign language-learning. Using a foreign language is certainly a major obstacle in problem solving in mathematics since it involves abstract thinking and mastery of mathematical terminology which make a high demand on language proficiency. %U http://www.sciencedomain.org/abstract/11876
