This is true since in writing, the students have to consider many writing aspects, such as content, organization, language use, vocabulary and mechanics; content is referring to the substance of writing, organization is concerning with the logical organization of the content, language use is focusing on the use of correct grammatical, vocabulary is dealing with the selection of words in the content and mechanics is referring to the use of graphic conventions of the language. The students mostly complain that they do not know how to express their ideas into words and they also have difficulty in how to compose sentences. As a result, the students have no motivation to write, and it makes writing becomes boring and hard activity for them. Meanwhile, roundtable technique is one of cooperative learning model in where the students work in groups and sit around the table. The most convenient aspect is that students can cooperate through some procedures such as writing, editing, and rewriting that can help them overcome their writing difficulties. Dealing with the problems, this research aims to see whether roundtable technique can be applied to increase the students? writing ability in descriptive text at the first year of SMA Xaverius Pringsewu.
