In the research on English writing, many scholars have conducted multi-angle investigations. For example, Nes discussed whether the explicit teaching method of critical thinking can improve the critical thinking ability of higher education English learners. Wei researched the application of cloud computing and speech recognition technology in English teaching. Rao took the primary schools in East Asia as the research object, studied the challenges faced by primary schools in the area, and proposed countermeasures to the challenges (Wang et al., 2017; Zhang et al., 2021; Nes et al., 2019). Explicit teaching is a vital teaching approach that includes a number of processes where the teacher defines the learning goals and performance criteria. It enables pupils to see the intentions and objectives. Explicit teaching separates learning into manageable pieces. It reduces a student's cognitive load, or the number of cognitive resources required to process data. Working memory is allowed when the cognitive burden is reduced. This is important because acquiring new skills requires a great deal of working memory. Therefore, relying on the background of “artificial intelligence + education”, this article explores the reform and innovation of English writing methods to promote the construction of English teaching informatization. The artificial intelligence will manage the good opportunities of language recognition for the teaching methods and the functions for the development of the teaching model for the background of the big data analytics for the traditional learning method here in this paper, both the online teaching and the traditional teaching methods are made to form in the artificial intelligence concept. The difference between the traditional teaching and online teaching method is that the traditional method is built on set schedules that require students and teachers to be present in the same geographical area at the same time. There are numerous ways to break this rigidity in online learning, including face-to-face online classes using virtual classrooms. The online teaching method will make good development in the network platform to produce the big data to manage the teaching effectiveness of the teacher and the listening power of the students here, the ability of the teacher and the students will be analyzed by the big data analysis method. Here, artificial intelligence makes the teaching reform for extensive data analysis.
