This study aims to understand the opinions of middle school and high school students about language learning and studying other content in an additional language in the school settings where English is used as the medium of instruction to teach more than 50% of the curriculum. For this end, 261 students from three different schools were administered a questionnaire. Results indicate students generally have very positive opinions about learning languages and studying content in their non-native language. There is no statistically significant difference between the students' opinion and their school level, and the years that they have been learning a language and studying content in an additional language. However, the students who have a negative opinion about the school have negative opinions about learning languages and studying content in an additional language. The possible reasons for these were evaluated from the perspective of language learning context but further study would be needed to establish causality.
