22 of errors taxonomy by Krashen. In this research, the researcher uses Dulay, Burt,
and Krashen’s theory to classify and explain the errors.
B. Theoretical Framework
The research problems focus on the errors made by the seventh semester students of English Language Education Study Program of Sanata Dharma
University academic year 20072008 in writing Research Proposal of Thesis Writing Course. The researcher also intends to investigate the possible sources
underlying the errors. Dealing with those two problems, the researcher uses theory of errors
classification and possible sources of errors. For classifying the errors, this research uses one of the theories of errors taxonomy by Dulay, Burt, Krashen
1998 as cited by Ellis Barkhuizen 2005; they are linguistic taxonomy and surface structure taxonomy. This research uses surface structure taxonomy theory
to classify the errors. In discussing the possible sources underlying the errors, the researcher
focuses on the use of theory stated by Ellis Barkhuizen 2005 and Brown 2000. There are three types of errors sources; intralingual, interlingual, and
induced error or context of learning sources. Interlingual source is when the errors produced by the learners because of the experience in learning language
influenced by mother tongue. While, intralingual source shows that the learners are irrespective of their LI. In this second source, the learners are irrespective in
learning L2 also. The last is natural error or called induced error Ellis and

23 Barkhuizen: 2005. Brown 2000 calls it as context of learning. It occurs because
of the way the language is taught in the classroom. James’ theory of strategies in analyzing errors is used by the researcher to help in analyzing and finding the
possible sources. Since the research does not focus on specific error, the discussion concerns with some theories of grammar. The researcher does not
include those theories in this chapter because some various errors likely appear in the research that cannot be predicted by the researcher.
