The study examined language features on discussion texts written by university students. The aim of this study is to explain what students language features used on discussion text are. The subject of this study is 28 students from third semester of English Education Department. This study is qualitative research. The procedure of data collections are from documentation of discussion texts written by 28 students who registered in Genre Based Writing course at UIN Walisongo. The researcher got the data from the lecturer. The advantages and disadvantages of this study was analyzed using Feez’s (1998) framework for discussion texts. The results showed that two students were unable to write discussion text correctly. Analysis of the language features in the student discussion texts revealed that students have variation in writing conditional clauses although they were seldom used to present hypothetical situations to move the arguments forward. On the other hand, connectors were frequently used, particularly “because”. More causal connectors were used than sequential connectors because of the need for reasoning in discussion texts. Shifts in arguments were signaled using adversative connectors but these were used less frequently than additive connectors for connecting similar ideas. The discussion texts were also characterized by the frequent use of modal verbs for hedging and boosting, mainly “can” and “will”. The study showed, while the students’ texts had the relevant language features of discussions, they sometimes lacked of comprehending the characteristic of word that they use to connect their sentence or arrange sentence particularly in writing conditional clause.
