摘要：This study is aimed to identify the effect of outline planning in writing argumentative essay.Outlining is making a plan to map your writing,which shows the content and sequence of each paragraphin your writing.Task planning will give the students an opportunity to plan what to say and how to write their ideas in the task performance.Task planning can be in the form of cubing,clustering,mapping (Ojima,2006:566),and outlining (Kellog,1990: 328).The data source of this study is argumentative essay writing of 30 students.The data in this study was analysed both qualitatively and quantitatively,by comparing the results of pre-test and post-test in argumentative essays writing.Pre-test was conducted without outlining the writing,while post-test proceeded by outlining the writing.Based on the data analysis,there is a significant improvement in students writing after implementing outline planning.The improvement reflected from the reductionof the types and number of mistake made by the students in their writing.
