To know the students who did grammatical errors in Recount Text was done through an instruction of writing free recount text. From the students’
Recount Text grammatical errors, it was chosen the learners to be interviewed to find out the interlanguage processes happened in it in detail. The technique in
choosing the interviewee was done using purposive sampling technique. Purposive sampling is a technique in choosing the sample as the data
source with certain consideration. The students who became the Subject of interview were they who made more grammatical errors than other. The amount
of the students who became the Subject of interview was based on the need of the data. According to Nasution 1998 quoted by Sugiyono, 2010: 302, the amount
of the sample Subject of interview is regarded as enough if it has been on the redundancy level which means that by using other sources of data the writer will
not get new information.
