The help of W micro-ability points to teaching is mainly reflected in: 1. According to the actual situation and needs of teachers, organize all kinds of training at all levels to improve teachers' information technology application ability. Information technology training should be targeted and effective. On the one hand, it is necessary to carry out targeted training combining information technology with course teaching; On the other hand, it is necessary to make a feasible training plan according to the existing technical level of teachers and the actual needs in teaching. For example, basic training for some older teachers with poor foundation, focusing on the operation of office software and the production of PPT; For young teachers with good network information foundation, focus on in-depth application. At the same time, take the form of "going out+please come in", send backbone teachers out to participate in training, and invite excellent information technology teachers from surrounding schools to teach; Internally, we should lead the whole team with the backbone, and improve teachers' innovative ability in using computer-aided teaching through mutual observation and experience introduction. Second, strengthen the construction of school education information resource database to facilitate teachers to use educational information technology for daily teaching. On the one hand, schools should establish subject resources with teaching and research groups as units. For example, electronic lesson plans, courseware, homework, etc. Organize and upload to the school server after preparing lessons collectively. At the same time, schools can also cooperate with brother schools to build school-based resources. This can not only learn from each other's strengths, but also reduce the workload of teachers. On the other hand, schools should make full use of online free education and teaching resources, or buy some high-quality resources to supplement their own construction. Third, optimize teaching methods and use information technology flexibly in the teaching process. There are many kinds of teaching methods, and adopting appropriate teaching methods will get twice the result with half the effort. In this regard, teachers should analyze the current situation of students' quality, information technology foundation and teaching objectives, adopt appropriate teaching methods, and combine the cultivation of students' innovative ability to continuously improve teaching methods and teaching concepts. For example, teachers can use multimedia equipment to show the information technology operations they need to learn on the stage, and then choose a student to operate on the stage. Explaining the problems in operation in a targeted way will not only help students identify the key points and difficulties, but also provide a platform for students to learn and show, and arouse their learning enthusiasm. Generally speaking, there are many ways to optimize teaching methods. Teachers can combine group learning, task-based teaching method, achievement display method and other teaching forms to tap students' collective wisdom and bring students a sense of accomplishment in information technology teaching.
