…………………………………………………………………………………………………….... Introduction:-Writing has been one of focus for Language Art education because the process of writing can cultivate students" various capabilities, including integration, expression, logic, organization, reflection, critical thinking, social cognitions, and appreciation. These capabilities not only contribute to personal daily life and academic performance, but also benefit the development of their careers in the future (Fitzgerald, 2013;). However, due to the complexity and difficulty of writing, many junior high students have negative feelings toward writing, even regard it as boring and stressful. Several studies conducted in Taiwan setting revealed that writing skills ought to be improved in secondary school level (Gao, 2006;Xu & Yang, 2010;Yang, 2006) such as purposive sampling, structure, organization, spelling, formatting, and punctuation. Many factors might contribute to the poor writing. One of them might be students themselves. According to Harris, Graham, and Adkins (2015), skilled writing is complex, requiring extensive self-regulation of a flexible, goal-directed, problem-solving activity. Knowledge about writing (including genre knowledge) and strategies for planning and text production are also critical . If students lack background knowledge about writing, interest, meta-cognition, and motivation, it is impossible to have good writing performance; another factor could come from teachers" teaching. If a teacher cannot apply the appropriate teaching model and strategies for writing, it might be impossible to deliver his/her teaching Corresponding Author:-Su-ching lin.
