Examining the Non-Language Students’ Awareness, Use, and Challenges in EMI Courses in a Tertiary School

English as a medium of instruction (EMI) enables learners across the world while navigating the unique challenges in the online learning environment. The study was conducted at Sultan Kudarat State University (SKSU)-College of Teacher Education to shed light on the place and role of EMI through descriptive-correlational research design. The 122 BSED students served as respondents and were selected through the probability sampling method. A validated survey questionnaire was used to identify the level of students' awareness on Executive Order No. 210 Series of 2003 section 2, the extent of use of the English language as a teacher's medium of instruction, and the challenges that students faced in using the EMI in online teaching in referenced to grammar, punctuation, vocabulary, and motivation. Results showed that students were aware of Executive Order No. 210 s. 2003 and often used the EMI in online teaching and learning. English Grammar, pronunciation, motivation, and vocabulary sometimes posed challenges in online learning. It concluded that there was a significant positive relationship between the students' awareness of the EO and their use of EMI. Hence, the study recommends strengthening the use of EMI among students across programs in the institution.
