This project develops an interactive mobile app entitled “Marine Biology (HKUST)”. Integrating augmented reality (AR) simulation aids with multi-modal learning resources, this educational app aims to enhance students’ learning and their engagement in different learning activities of a laboratory course, including the essential language skills for presenting lab reports in writing and presentations. The app includes a variety of user-friendly and key English learning materials to enhance students’ abilities in scientific writing and speaking: report writing skills, presentation tips, vocabulary quizzes, scientific writing samples, a glossary of vocabulary for describing marine species, and core grammar for report writing.
