The first part of the article describes the problems of teaching listening comprehension in foreign language classes. A trial experiment was conducted, aimed at determining the effectiveness of collaborative writing of transcripts for foreign-language professionally orientated videos. We compared the effectiveness of giving detailed answers to the questions about the content of the videos to the effectiveness of writing a transcript. We also established that doing listening comprehension assignments collaboratively was more effective than individual work. The experiment allowed us to make a conclusion that foreign language listening comprehension competence can be formed more efficiently via writing transcripts collaboratively. Higher results in the experimental group were achieved because the students got deeper insights into the video in the course of writing the transcripts. Due to involvement of each student in the collaborative work, the experimental groups made more progress in listening comprehension.
