Good grammar is one of the main requirements for descriptive writing. The use of digital platforms for learning can also support the development of learning in the 21st century. The aims of this research are to find out the challenges faced by students and to know how BBC Learning English improves students’ understanding and application of grammatical rules in descriptive writing. This research used classroom action research. The data was collected from observations, questionnaires, tests, and interviews. There were 35 participants and 6 interviewees at Sanata Dharma University.

The research results found that most students knew the basics of English for grammar and writing quite well. However, students still needed a lot of reading and writing practice. Besides, they had difficulties staying focused because they were distracted by cell phones and lacked time to complete assignments and tests. The researcher provided reading sessions and writing practice, analyzed grammatical errors in descriptive writing, and increased interaction with students to face these challenges. Students also agreed that there has been quite significant progress in learning grammar in descriptive writing using BBC Learning English.
