In this pilot project, nine pairs of Danish teenagers with different levels of English proficiency were observed and of these three pairs were studied in greater detail, as they worked on English writing assignments on a word processor. The approach used in gathering data was based on video recordings using a split-screen technique. Half the screen showed the progression of the written text, while the other half showed what the pair of students were saying and doing. Included are a table showing when each pair was observed, their grade and English proficiency level at the time of observation, a thorough description of each assignment, observation "notes" on the work done and the students' collaboration, the final texts produced by students, a summary of the students' work, and an analysis of the difficulties perceived by the students while formulating the written text in their collaborative processes.
