本研究旨在探讨过程写作法在高中英语写作教学中的应用及其影响。研究对象为某高中二年级两个班的学生。在为期三个月的教学实践中,两个班均接受了相同的写作测试与问卷调查,但不同的是实验班采用了过程写作法,而控制班则使用了传统的成果写作法。研究通过SPSS软件对量化数据进行了统计分析,并对实验班的部分学生进行了访谈以收集质性数据。结果表明,过程写作法应用于高中英语写作教学不仅能有效转变学生对英语写作的态度,而且还能显著提高学生写作能力。This study aims to explore the application and impact of the process writing approach in senior high school English writing teaching. The research subjects were students from two classes in grade two of a senior high school. During the three-month teaching practice, both classes underwent the same writing tests and questionnaire surveys. However, the experimental class adopted the process writing approach, while the control class used the traditional product writing approach. Quantitative data were statistically analyzed using SPSS, and qualitative data were collected through interviews with some students from the experimental class. The results showed that the application of the process writing approach in senior high school English writing teaching can not only effectively change students’ attitude towards English writing, but also significantly improve students’ writing ability.
