Insights to Improve Online Content and Language Integrated Learning (CLIL) Sessions on Biorefineries: A Case Study for University Students in Spain

The implementation of educational programs that tackle specific contents and promote English skills is convenient, especially in areas where English skills are not properly developed at universities, such as Spain. Indeed, some subjects are currently presented in English for this purpose. CLIL (Content and Language Integrated Learning), where students learn English as a part of specific subject goals of their degree, could be a suitable way to improve English skills while acquiring the corresponding competences. Moreover, online lessons are becoming important, especially during the COVID-19 outbreak, when it was an alternative for face-to-face teaching. The aim of this work was the implementation of an online CLIL course about biorefineries for chemistry, chemical engineering, and mechanical industrial engineering students. The course was a first approach presented as a specialization course that could be merged with related subjects in the future. The main objective of this session was the gradual introduction of English grammar and vocabulary (specific terms) and the promotion of students' participation on oral discussions. The results were successful, showing that the students got motivated and obtained good grades. As possible improvements, the introduction of terms should be less continuous, otherwise the students could lose track of the lesson.
